The Samsung Odyssey Neo G9 is a super ultrawide gaming monitor with a 49 inch screen and 32:9 aspect ratio. It's an upgraded model of the Samsung Odyssey G9 that features Mini LED backlighting, allowing it to get brighter and have greater control over the local dimming. In fact, it has the best local dimming we've seen on any LED-backlit monitor as it rivals that of TVs and helps it display deep blacks. Since it's a gaming monitor, it has a high 240Hz refresh rate with native support for FreeSync variable refresh rate (VRR) technology and G-SYNC compatibility to reduce screen tearing. It's even future-proof as it has HDMI 2.1 inputs so you can take full advantage of the next-gen gaming consoles or graphics cards. It delivers stunning picture quality in SDR, and the HDR experience has drastically improved with the latest firmware update.
The Samsung Odyssey Neo G9 is great for most uses. The large, high-resolution screen provides enough space for multitasking and it gets bright enough to combat glare in a well-lit office space. It's great for content creators and media consumers because it displays deep blacks and has a good local dimming feature. It's also excellent for gaming as it has two HDMI 2.1 inputs with a high refresh rate, VRR support, low input lag, and a quick response time.
The Samsung Odyssey Neo G9 is good for office use. It has a large 49 inch screen with a 5120x1440 resolution, so you can easily open multiple windows side-by-side. Visibility shouldn't be an issue in most bright environments because it has fantastic peak brightness and decent reflection handling. Unfortunately, it has narrow viewing angles and an aggressive curvature so it's not ideal for sharing with a coworker or client.
The Samsung Odyssey Neo G9 is excellent for gaming. It has a 240Hz refresh rate with native FreeSync and G-SYNC compatibility, but there are some bugs with its VRR. It has low input lag and a quick response time, but its response time is slower than most 240Hz monitors. It also has HDMI 2.1 inputs for high frame rate gaming. It's fantastic for dark room gaming because it displays deep blacks and has a good local dimming feature.
The Samsung Odyssey Neo G9 is great for consuming multimedia content. The 32:9 aspect ratio and 49 inch screen allow you to watch your favorite shows while having other windows open next to it, but there will be black bars if you watch content in full-screen mode. It performs best in dark rooms because it has a high native contrast to display deep blacks, and even in bright rooms, it gets bright enough to fight glare.
The Samsung Odyssey Neo G9 is great for content creators. The super ultrawide screen provides enough space so you can see all your work in front of you without having to scroll. It displays a wide SDR color gamut with excellent coverage of the Adobe RGB color space. It also has fantastic brightness and decent reflection handling if you work in a well-lit office. Sadly, it has narrow viewing angles so it's not a good choice to share your screen with someone else. Also, its aggressive curve may not be ideal for photo editing with straight lines.
The Samsung Odyssey Neo G9 is an impressive monitor for HDR gaming. It has great contrast which is significantly improved by the Mini LED backlight, and black uniformity with local dimming is nearly perfect. It also has great peak brightness in HDR, and most of the initial issues we experienced with the monitor have been fixed with the latest firmware. Finally, it can display a wide color gamut, and it has two HDMI 2.1 ports for Xbox Series S|X and Sony PS5 gamers.
The Samsung Odyssey Neo G9 is a large monitor with an aggressive curve. It looks a lot like the Samsung Odyssey G9 with black borders on the front and a white panel in the back. The stand is also black but has a white panel cover for cable management. It's mainly plastic with a bit of chrome trim around.
The Samsung Odyssey Neo G9's stand is wide-set and takes up a lot of space, but the feet are spread apart, so you can still place stuff in front. The stand holds it well considering the size of the screen, but you may still notice some wobble, which is normal.
Due to the super ultrawide format, the Samsung Odyssey Neo G9 has somewhat limited ergonomics. You can adjust the height, tilt it, or swivel it a bit, but you obviously can't rotate it into portrait mode.
The back of the Samsung Odyssey Neo G9 is exactly like the Samsung Odyssey G9. It's mainly white with a bit of texture and black trim throughout. There's a ring that lights up in blue where the stand attaches to the screen. Cable management is done through the stand and there are covers on the stand and back panel to keep the setup clean.
Due to the Samsung Odyssey Neo G9's aggressive curve, the screen is very thick and takes up a ton of space. You need a big desk to place it on.
The Samsung Odyssey Neo G9 has great build quality. It's mainly made of plastic, but the stand is sturdy metal and supports the screen well considering its large size. The plastic on the back feels decent, but the cover for the inputs is flimsy. The height adjustment on the stand isn't the best as it doesn't stay in place when you set it to its lowest. Overall, besides these minors issues, it's a solid monitor, and there's nothing cheap about it.
The Samsung Odyssey Neo G9 has a great contrast ratio. The native contrast is very good, which is typical of VA panels, and the local dimming feature does an incredible job at improving the contrast. It displays deep blacks when viewed in the dark, and it's actually the best contrast with local dimming that we've seen on an LED-backlit monitor. Keep in mind that contrast can vary a bit between units.
The Samsung Odyssey Neo G9 has a good full-array local dimming feature. It's the first monitor we've tested with Mini LED backlighting, and it has 2048 zones. It does a fantastic job at improving the contrast to display really deep blacks, and even though it crushes some details in dark scenes, it's really not that bad. There's minimal blooming around bright objects if you're looking at it from directly in front, but it's more noticeable from the side due to the narrow viewing angles, which you can see with the video above. However, we don't recommend using the local dimming feature for productivity if you're using a browser in dark mode because the zones light up for small UI elements, which could get distracting.
We recommend setting Local Dimming to 'High' for gaming or for watching movies because that's where it performs best. Fast-moving objects transition between the zones well, but the local dimming struggles to keep up with very fast objects. There's minimal blooming around subtitles that you shouldn't notice with real content. Uniformity is very good and it even displays black bars well if you're watching content that isn't 32:9.
We tested the local dimming with Adaptive Sync and Low Input Lag enabled and there isn't much of a difference when using either of those modes.
Overall, the local dimming is better than any other monitor we've tested as it helps to improve the contrast and make highlights pop. It looks really good when viewing from the center, but there's more blooming when looking at it from the side. It's on par with some local dimming features on TVs, but don't compare the score with TVs. Instead, we took real content local dimming videos like we do with TVs so you can see how it looks:
The Samsung Odyssey Neo G9 has fantastic SDR peak brightness thanks to the Mini LED backlighting. It easily gets bright enough to fight glare in most rooms. Brightness varies between different scenes, particularly with larger areas of bright colors due to the aggressive Automatic Brightness Limiter. Samsung advertises a typical brightness of 420 cd/m², which we achieved by disabling local dimming in the 'sRGB' mode, so the brightness depends on which settings or modes you're using.
We tested it after calibration in the 'Custom' Picture Mode with Brightness at '100' and Local Dimming on 'High'.
Note: Our results may be brighter than other reviewers because we purchased a retail unit with firmware 1006.1. Other reviewers may be using pre-release firmware.
Update 10/19/2021: We retested the Neo G9 with the latest firmware (1007.3), and the backlight behavior has completely changed in HDR, and it's brighter overall, but small highlights aren't as bright.
The Samsung Neo G9 has excellent HDR peak brightness. It's bright enough for small highlights to really stand out, and it's one of the few monitors that delivers a true cinematic HDR experience.
We tested it in the HDR Dynamic mode with Brightness at '100' and Local Dimming on 'High'. Although not usually part of our testing for monitors, we also measured the EOTF to see how accurately the backlight follows the creator's intent, which is very important for a good HDR experience. Both HDR modes crush dark scenes a bit, and both over-brighten bright scenes, but Dynamic is even brighter in bright areas. We also tested it with HDR Standard, and you can see the results below:
The Samsung Odyssey Neo G9 has narrow horizontal viewing angles, which is expected from a VA panel. The image looks washed out if you view off-center. The edges of the screen may look inaccurate if you sit too close, but the curve is supposed to help with this. However, our testing doesn't take the curvature into account.
Once again, the vertical viewing angles are narrow on the Samsung Odyssey Neo G9. The image looks inaccurate if you mount it above eye level.
The Samsung Neo G9 has amazing gray uniformity. Despite the large size, the entire screen looks uniform. There's some backlight bleed in near-dark scenes, but it's not too distracting. Keep in mind that uniformity can vary between units, but it's rarely an issue on monitors.
There are reports of the backlight grid being visible on some units. It's not very noticeable on ours, but you can still see it if you look closely. Let us know if you see it on yours.
The Samsung Odyssey Neo G9 has poor black uniformity with local dimming disabled because there's a ton of backlight bleed and some blooming around the center cross, which explains why the overall uniformity score is low. However, the local dimming significantly improves the uniformity as the entire screen looks black and the uniformity is nearly perfect. Note that uniformity can vary a bit between units.
The Samsung Neo G9 has decent out-of-the-box accuracy. White balance is off, particularly with pure white, and most colors are a bit inaccurate. The color temperature is colder than the target, giving the image a blueish tint. Also, gamma seems to follow a flat 2.3 target instead of the sRGB curve so most scenes are darker than they should be.
The Samsung Neo G9 has fantastic accuracy after calibration. Any remaining inaccuracies with colors and the white balance are nearly impossible to spot. The color temperature is nearly spot-on with the 6500K target and gamma is improved, but some scenes are slightly over-brightened.
You can download our ICC profile calibration here. This is provided for reference only and shouldn't be used, as the calibration values vary per individual unit even for the same model due to manufacturing tolerances.
The Samsung Odyssey Neo G9 has an incredible SDR color gamut. It has perfect coverage of the commonly-used sRGB color space and excellent coverage of the Adobe RGB color space used in photo editing, which is an improvement over the Samsung Odyssey G9.
The Samsung Odyssey Neo G9 has outstanding color volume in SDR. Thanks to its high brightness, great contrast, and incredible color gamut, it displays colors at a wide range of shades and luminance levels.
Update 10/19/2021: We retested the HDR color gamut with the latest firmware. There's very little difference in the actual color gamut, but the tone mapping is a bit worse overall in DCI P3. We also measured the tone mapping in DCI P3 and Rec. 2020 in both 'Standard' and 'Dynamic' modes:
The Samsung Odyssey Neo G9's HDR color gamut is very good. It has fantastic coverage of the DCI P3 color space that's used in most HDR content, but it has more limited coverage of Rec. 2020. We tested it using the HDR Dynamic mode, and we also measured the color gamut with HDR Standard:
Coverage between both modes seems to be the same, but tone mapping is different as Standard seems to have more accurate colors. However, Standard is worse at displaying pure white than Dynamic, and since Dynamic gets brighter, it's a better choice to watch HDR content for most people.
Update 10/19/2021: We retested the HDR color volume with the latest firmware. There's very little difference in color volume.
The Samsung Neo G9 has good HDR color volume. It does a good job at displaying colors at a wide range of luminance levels. Once again we measured it with the HDR Dynamic mode, but also with HDR Standard:
Unfortunately, the Samsung Odyssey Neo G9 has some very minor signs of temporary image retention after displaying a high-contrast static image. It's not very noticeable and it disappears quickly. The retention after 4 minutes is due to a rounding error and isn't noticeable. Keep in mind that image retention can vary between units.
The Samsung Neo G9 has exceptional gradient handling. You shouldn't notice any banding.
There are no signs of color bleed on the Samsung Odyssey Neo G9, but this can vary between units.
The Samsung Odyssey Neo G9 has decent reflection handling. It scores a bit worse than the Samsung Odyssey G9, but they look the same and the differences are minimal. Combined with the fantastic peak brightness, visibility shouldn't be an issue in most rooms. Light reflects from the center of the screen due to the curvature.
The Samsung Neo G9 has good text clarity thanks to the high resolution. Enabling Windows ClearType (top photo) helps improve the appearance of diagonal lines as seen on R, N, G, and S.

The Samsung Odyssey Neo G9 has a good overall response time. It has the quickest rise/fall response time out of all 240Hz monitors we've tested, even faster than the Samsung Odyssey G9, but its total response time is one of the slowest. There's significant overshoot in all transitions, which is why we recommend using the 'Standard' setting which has the least amount. Enabling Adaptive Sync also locks you out of any overdrive settings, so we measured the response time in VRR too, and it performs similarly to the 'Standard' setting. We also didn't notice any black smearing, which is rare for a VA panel.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The response time at 60Hz is excellent. The Samsung Neo G9 shows the same behavior at 60Hz as at 240Hz because there's still overshoot in all overdrive settings, but there's the least with 'Standard'. This means you won't have to change the setting if the frame rate of your game drops. Once again, the response time is about the same in VRR as with the 'Standard' setting.
The Samsung Odyssey Neo G9 has a flicker-free backlight, which helps with eye strain. Unlike the Samsung Odyssey G9, it stays flicker-free with the backlight set at '0'. However, we noticed some flickering issues like the Odyssey G9 in VRR with lower-frame rate content (see Refresh Rate).
The Samsung Neo G9 has a backlight strobing feature, commonly known as black frame insertion. The feature only works between 120Hz and 240Hz because even if you set it to 60Hz it still flickers at 120Hz. This causes image duplication as you can see in this photo. You also can't use the BFI feature with Adaptive Sync enabled, so you'll need to disable it for the BFI feature to be available.
The Samsung Odyssey Neo G9 has a 240Hz refresh rate with native FreeSync support and G-SYNC compatibility to reduce screen tearing. You can achieve the full refresh rate with a DisplayPort connection, and we tested it with a PC using an RTX 3070 graphics card. Over HDMI, it supports both FreeSync and G-SYNC up to 144Hz, but you need an HDMI 2.1 source; we tested it with a Radeon RX 6800 graphics card. We didn't test to see if FreeSync works with an HDMI 2.0 source, but the max refresh rate over HDMI 2.0 should be 60Hz.
Like the Samsung Odyssey G9, the Neo G9 has flickering issues with lower-frame rate or dim content that could get distracting. The flicker is noticeable, with some scenes more than others. Samsung added a VRR Control setting to help reduce this issue by doubling the frames with lower-frame rate content, which helps improve it but also causes some stuttering.
The Samsung Neo G9 has incredibly low input lag for a responsive gaming experience. However, we ran into issues trying to measure the input lag at 60Hz, which are listed below:
|Monitor Refresh Rate||PC Refresh Rate||VRR||Input Lag||Notes|
|60Hz||60Hz||No||8.9 ms||Measured 60Hz Native Resolution input lag|
|120Hz or 240Hz||60Hz||No||21 ms||Inconsistent readings|
|120Hz or 240Hz||120Hz or 240Hz||Yes||-||Can't set monitor's refresh rate to 60Hz|
|120Hz or 240Hz||60Hz||Yes, but G-SYNC disabled||9.1 ms||G-SYNC doesn't work if enabled, so we can't use these results.|
Essentially, you need to make sure your PC and monitor are both set at the same refresh rate to achieve low input lag.
We couldn't measure the 10-bit HDR input lag either because we couldn't achieve the max refresh rate with a 10-bit signal using our tool, which uses HDMI 2.0. That said, we don't expect HDR to increase the input lag.
The Samsung Neo G9 has a large screen with a high resolution that's the equivalent of placing two 27 inch, 1440p monitors side-by-side.
The Samsung Neo G9 has two HDMI 2.1 inputs, whose bandwidth is 40 Gbps, which you can see here. You can achieve a max refresh rate of 144Hz with a 10-bit signal at 5120x1440 and with chroma 4:4:4 over HDMI. We also checked to see what resolutions it supports from the Xbox Series X and PS5. Keep in mind we didn't test the scaling performance from the consoles.
The Samsung Odyssey Neo G9 has a few extra features, including:
The Samsung Neo G9 also supports HDR10, and most of the issues we experienced with HDR have been fixed with the latest firmware.
There's a joystick and three buttons to control the on-screen display underneath the right side of the Samsung Neo G9.
We tested the 49 inch Samsung Odyssey Neo G9, which is the only variant available for the 2021 model in the AG900 lineup. It's an updated version of the Samsung Odyssey G9 from 2020 with Mini LED backlighting. It's part of Samsung's Odyssey Series, which includes the models listed below. The results for this monitor aren't valid for those.
|Size||Model Name||Short Model Code||Refresh Rate||Resolution||HDMI Type|
|27", 32"||Odyssey G7||LC27G75T/LC32G75T||240Hz||2560x1440||2.0|
|49"||Odyssey Neo G9||LS49AG952N||240Hz||5120x1440||2.1|
If someone comes across a different type of panel or if their Samsung Odyssey Neo G9 doesn't correspond to our review, let us know and we'll update the review. Note that some tests, like gray uniformity, may vary between units.
Our unit of the Neo G9 was manufactured in June 2021; you can see the label here.
The Samsung Odyssey Neo G9 is a great overall monitor with Mini LED backlighting. It has the best local dimming feature we've seen on any LED-backlit monitor and it gets very bright. It has HDMI 2.1 inputs, which is an advantage if have you the next-gen gaming consoles, but it doesn't offer anything different if you use a DisplayPort connection. The issues with HDR have been nearly completely fixed with the latest firmware.

The Samsung Odyssey Neo G9 replaces the Samsung Odyssey G9 and upgrades in a few ways. The major difference is that the Neo G9 has Mini LED backlighting, so it gets brighter and has much better local dimming. It also has HDMI 2.1 inputs, while the G9 has HDMI 2.0, so you can achieve a higher refresh rate over HDMI on the Neo G9. The G9 has slightly better response times, but it's not really a noticeable difference.
The Samsung Odyssey G7 LC32G75T and the Samsung Odyssey Neo G9 are both excellent gaming monitors with different screen sizes. The Neo G9 is a super ultrawide monitor with a 49 inch screen and 32:9 aspect ratio, while the G7 is available in 27 and 32 inch sizes with a 16:9 aspect ratio. The Neo G9 has Mini LED backlighting which provides better control over the local dimming, so it displays deeper and more uniform blacks. The Neo G9 also gets brighter. The G7 has better motion handling because it has quicker response times and less overshoot on the 'Standard' overdrive setting than the Neo G9.
The Gigabyte M27Q and the Samsung Odyssey Neo G9 are very different types of monitors. The Gigabyte is a 27 inch 1440p monitor, while the Samsung is a 49 inch, 5120x1440 display, which is the equivalent of placing two of the Gigabytes side-by-side. The Gigabyte also has an IPS panel with wider viewing angles, and the Samsung has a VA panel with much better contrast. The Samsung features Mini LED backlighting, meaning it gets much brighter, and it has a good full-array local dimming feature. However, motion looks much smoother on the Gigabyte because there's less overshoot.
The Samsung Odyssey Neo G9 is an overall improvement from the Samsung C49RG9/CRG9, which came out two years before the Neo G9. The Neo G9 has HDMI 2.1 inputs, meaning you can achieve a much higher refresh rate over HDMI, and it has a 240Hz max refresh rate compared to 120Hz on the CRG9. The Neo G9 also has better motion handling because it has a much quicker response time on the 'Standard' overdrive setting. The Neo G9 uses Mini LED backlighting, allowing it to get a bit brighter and have a much better local dimming feature, so there's less blooming.
The Samsung Odyssey Neo G9 is a different type of display than the LG 48 C1 OLED, even though they have similar screen sizes. The Samsung is a super ultrawide LED monitor with a 32:9 aspect ratio, and the LG is a TV that we tested as a monitor, so it has a more traditional 16:9 aspect ratio. The LG has an OLED panel, providing a near-infinite contrast ratio and perfect black uniformity, but the Samsung's LED panel gets significantly brighter. They each have HDMI 2.1 inputs, but the Samsung has a much higher 240Hz refresh rate, which you can achieve using a DisplayPort connection, compared to the LG's 120Hz. Despite the faster refresh rate, the LG has a near-instantaneous response time, so motion looks better. The main advantage of the LED panel over the OLED is that the Samsung won't suffer from the risk of burn-in.
The Samsung Odyssey Neo G9 and the LG 38GN950-B are both ultrawide gaming monitors with different panel types and screen sizes. The Samsung has a larger 49 inch screen with a 32:9 aspect ratio compared to the 38 inch screen and 21:9 aspect ratio on the LG. The Samsung also has a VA panel with a better contrast, but the LG's IPS panel has better viewing angles. Even though the Samsung has a higher 240Hz refresh rate, motion handling is better on the LG. They both have local dimming features, but it's much better on the Samsung thanks to the Mini LED backlighting.
The Samsung Odyssey Neo G9 and the LG 49WL95C-W are different types of super ultrawide monitors. The LG has a focus on productivity so it has a less aggressive curve, making it easier to share your screen with others, and it has wider viewing angles. The LG also has a better selection of inputs like a USB-C input. However, the Samsung is an ultrawide gaming monitor with a much higher 240Hz refresh rate and VRR support. Its VA panel has a better contrast ratio, and it has Mini LED backlighting, which allows it to get brighter and have good local dimming.
The Samsung Odyssey Neo G9 and the Gigabyte AORUS FO48U OLED use different panel technologies, each with strengths and weaknesses. The Samsung has an ultrawide VA panel, and it's significantly brighter than the Gigabyte. The Gigabyte, on the other hand, has an OLED panel, which delivers much deeper, inky blacks with perfect uniformity and no blooming around bright objects. Unfortunately, this OLED panel also comes with a risk of permanent burn-in.
