This monitor was replaced by the Samsung Odyssey Neo G9

The Samsung Odyssey G9 is a super ultrawide gaming monitor. It has a large 49-inch screen with a 32:9 aspect ratio and 5120x1440 resolution, which is the equivalent of placing two 27-inch, 1440p monitors next to each other. It also features an aggressive 1000R curved screen to bring the edges within your field of vision. It's designed for gaming with a fast 240Hz refresh rate, native FreeSync variable refresh rate (VRR) support, and G-SYNC compatibility to reduce screen tearing. It doesn't have Mini LED backlighting like the model that eventually replaced it, the Samsung Odyssey Neo G9, but it still features a VA panel with edge-lit local dimming.

Our Verdict

7.6 Mixed Usage

The Samsung Odyssey G9 is an overall good monitor. It has great gaming performance thanks to its low input lag, fast response time, and high refresh rate. Its large screen provides plenty of space to work comfortably, and it has a high pixel density to render text clearly. Unfortunately, it has narrow viewing angles, which isn't ideal for sharing content or playing co-op games. On the bright side, it can display a wide color gamut and gets bright enough to deliver a decent HDR experience.

Pros
  • Good reflection handling.
  • Decent contrast ratio.
  • Large screen size.
Cons
  • Terrible local dimming.
  • Sub-par viewing angles.
  • Aggressive 1000R curve.
7.6 Office

The Samsung Odyssey G9 is decent for office use. Its 49-inch screen allows you to have multiple windows opened side-by-side, and its high pixel density results in sharp images and text. Unfortunately, it has limited ergonomics and sub-par viewing angles, making it hard to adjust the screen to your optimal viewing position or share work with your coworkers.

Pros
  • Good reflection handling.
  • Large screen size.
Cons
  • Sub-par viewing angles.
  • Aggressive 1000R curve.
8.3 Gaming

The Samsung Odyssey G9 is great for gaming. It has low input lag, a fast response time, and a high refresh rate, resulting in a responsive and smooth gaming experience. It supports FreeSync to reduce screen tearing and is compatible with NVIDIA's G-SYNC. However, there are limitations regarding its 240Hz refresh rate, as it's only achievable with certain graphics cards that support compression. Also, it has bad black uniformity, so it isn't the best option for gaming in the dark.

Pros
  • Good response time.
  • High refresh rate.
  • Decent contrast ratio.
  • Large screen size.
Cons
  • Poor black uniformity.
  • Terrible local dimming.
  • Aggressive 1000R curve.
7.2 Media Consumption

The Samsung Odyssey G9 is good for media consumption. It has a large screen and high resolution to deliver an immersive viewing experience. However, even though it has a decent native contrast, it has terrible local dimming, and it has bad black uniformity, making it less ideal for dark rooms. Additionally, it has sub-par viewing angles, so it isn't the best choice for sharing content.

Pros
  • Good reflection handling.
  • Decent contrast ratio.
  • Large screen size.
  • Outstanding gray uniformity.
Cons
  • Poor black uniformity.
  • Terrible local dimming.
  • Sub-par viewing angles.
  • Aggressive 1000R curve.
7.4 Media Creation

The Samsung Odyssey G9 is good for content creators. It has a large screen and high resolution, allowing you to work with multiple windows opened side-by-side to improve your workflow. It handles reflections well and gets bright enough to overcome glare. It isn't the best option for sharing your work, though, as it has narrow viewing angles. On the upside, it has near-full coverage of the sRGB color space and decent color accuracy before calibration.

Pros
  • Good reflection handling.
  • Decent contrast ratio.
  • Large screen size.
  • Outstanding gray uniformity.
Cons
  • Poor black uniformity.
  • Sub-par viewing angles.
  • Aggressive 1000R curve.
6.8 HDR

The Samsung Odyssey G9 is alright for HDR. It gets bright enough to make highlights pop and displays a wide range of colors in HDR. It has a decent native contrast ratio for deep blacks but has a terrible local dimming feature that causes a lot of blooming around bright objects.

Pros
  • Large screen size.
Cons
  • Terrible local dimming.
  • Aggressive 1000R curve.

Compared To Other Monitors

The Samsung G9 is a great super ultrawide gaming monitor that fills a need for a niche of gamers that want the large screen for immersive gaming instead of getting a few monitors in a multi-monitor setup. While it offers a great gaming performance, it was later replaced by the Samsung Odyssey Neo G9 which offers better picture quality with improved local dimming, so if you want an ultrawide monitor, the Neo G9 is the better choice.

You can also check out our recommendations for the best ultrawide gaming monitors, the best 34 inch + monitors, and the best 240Hz monitors.

Samsung C49RG9/CRG9

Overall, the Samsung Odyssey G9 is a bit better than the Samsung C49RG9/CRG9, mainly due to its higher refresh rate and lower input lag. However, the CRG9 has significantly less overshoot when running at its maximum refresh rate even though its response time is slightly slower, and it gets much brighter in SDR.

Dell Alienware AW3423DW

The Dell Alienware AW3423DW is better all-around than the Samsung Odyssey G9. The Dell delivers better picture quality because it uses a QD-OLED panel with deeper blacks, so if you want something for dark room gaming, you can't go wrong with it. The Samsung is a better choice if you want to play high-frame-rate games because it has a higher refresh rate, and the larger screen offers a more immersive experience.

LG 49WL95C-W

The LG 49WL95C-W and the Samsung Odyssey G9 are very different despite having the same size, resolution, and aspect ratio. The LG is a productivity monitor with a basic 60Hz refresh rate with no VRR support, while the Samsung is more gaming-focused, with a 240Hz refresh rate. The LG has an IPS panel with wider viewing angles, but it isn't as good for dark rooms as the Samsung because it has a low contrast ratio. The Samsung delivers a much better HDR experience because it has a wider color gamut and gets a lot brighter in HDR.

Samsung C49HG90/CHG90

The Samsung Odyssey G9 is a bit better than the Samsung C49HG90/CHG90. The G9 has a higher resolution, a higher refresh rate, and gets a lot brighter in SDR and HDR. However, the CHG90 has a higher contrast ratio to produce deeper blacks.

Samsung Odyssey Neo G9

The Samsung Odyssey Neo G9 replaces the Samsung Odyssey G9 and upgrades it 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.

Dell U4919DW

The Samsung Odyssey G9 and the Dell U4919DW have the same size, aspect ratio, and resolution; however, they're intended for different uses. The Samsung is a gaming monitor with faster response time, lower input lag, and a much higher refresh rate. On the other hand, the Dell is an office monitor with much wider viewing angles, better reflection handling, and better color accuracy out-of-the-box.

Dell Alienware AW3821DW

The Samsung Odyssey G9 and the Dell AW3821DW are two great gaming monitors, but with different features. The Dell has an IPS panel with wide viewing angles, making it easier to share your screen for co-op gaming. It also has native G-SYNC support and a quicker response time at its max refresh rate. The Samsung has a VA panel with a better contrast ratio, so it can display deeper blacks. It has a higher 240Hz refresh rate and native FreeSync support. Also, it has a much wider 49-inch screen and 5120x1440 resolution, making it a better choice for atmospheric gaming. Choosing one over the other really comes down to personal gaming preferences.

Samsung Odyssey G7 C32G75T

Overall, the Samsung Odyssey G7 C32G75T is better than the Samsung Odyssey G9. The G7 has a higher contrast ratio, significantly faster response time, and a black frame insertion feature to improve motion clarity. However, the G9 has a bigger screen and gets much brighter.

Samsung Odyssey Neo G8 S32BG85

The Samsung Odyssey Neo G8 S32BG85 and the Samsung Odyssey G9 are different types of monitors. The Neo G8 is a 4k display with a standard 16:9 aspect ratio, while the G9 is a super ultrawide monitor with a 32:9 aspect ratio, which is the equivalent of placing two standard monitors next to each other. The picture quality is much better on the Neo G8 because it has Mini LED backlighting which the G9 doesn't have, providing better control over its local dimming zones.

Samsung Odyssey Neo G7 S32BG75

The Samsung Odyssey G9 is a different monitor than the Samsung Odyssey Neo G7 S32BG75. While the G9 has a super ultrawide screen with a 32:9 aspect ratio, the G7 has a standard 16:9 screen with a higher 4k resolution. The G9 has a higher 240Hz refresh rate, but the motion handling is better on the G7. If you care about picture quality, the G7 is the better choice as it uses Mini LED backlighting to produce deeper blacks than the G9.

Gigabyte G34WQC

The Gigabyte G34WQC and the Samsung Odyssey G9 score similarly overall, but there are many differences between them. The Gigabyte has a 21:9 aspect ratio, whereas the Samsung has a 32:9, which is much wider. The Samsung has a higher refresh rate of 240Hz, significantly higher HDR peak brightness, and faster response time, although with more overshoot. The Gigabyte has a higher contrast ratio and a Black Frame Insertion feature.

LG 34GN850-B

The LG 34GN850-B is marginally better than the Samsung Odyssey G9. The LG has an IPS panel with much wider viewing angles, better color accuracy, and significantly faster response time when running at its maximum refresh rate. However, the Samsung has a bigger 32:9 screen, a better contrast ratio, and a higher refresh rate.

LG 38GN950-B

The LG 38GN950-B and the Samsung Odyssey G9 are both great ultrawide gaming monitors but also very different. The LG is a 38-inch IPS model with a 21:9 aspect ratio, while the Samsung is a 49-inch VA model with a 32:9 aspect ratio. This means that the Samsung has a wider format and is better suited for dark rooms, but its viewing angles are worse. The Samsung has a higher refresh rate of 240Hz compared to the LG's 160Hz; however, the LG has significantly better response times. The LG has a much wider color gamut, especially its DCI P3 coverage, and it gets brighter in HDR real scenes, though the Samsung can get brighter in some instances.

LG 38GL950G-B

The LG 38GL950G-B is better than the Samsung Odyssey G9 overall; however, they're very different monitors. The LG has an IPS panel with much wider viewing angles, better color accuracy, and significantly faster response time. The Samsung has a VA panel, gets a lot brighter, and has a higher refresh rate. The Samsung has native FreeSync support, while the LG is a G-SYNC monitor.

Acer Nitro XV340CK Pbmiipphzx

Overall, the Acer Nitro XV340CK Pbmiipphzx is a bit better than the Samsung Odyssey G9. The Acer has an IPS panel with much wider viewing angles, significantly faster response time, and a Black Frame Insertion feature to help reduce motion blur. However, the Samsung has a bigger screen for a more immersive gaming experience, a higher refresh rate, and it gets much brighter in both SDR and HDR.

Build Quality

The build quality is great. The body is made out of decent-quality plastic, and the stand is metal but covered with a plastic shell. This plastic shell and the headphone hook both feel flimsy, but this isn't an issue unless you're constantly playing around with them. There aren't any obvious issues with how it's put together, but it wobbles a lot, which is somewhat expected of a center-mounted super ultrawide monitor.

The ergonomics are alright. Despite its curved screen an super ultrawide display, you can still adjust it in a few different ranges, which is useful, but the tilt and swivel ranges are limited.

The back of the monitor has a gamer-oriented design with white plastic. There's some RGB lighting where the stand connects to the screen, and there's a small plastic hook near the top of the stand to hold your headphones. The stand's white plastic cover is removable, allowing you to hide the cables and route them to the bottom for cable management.

Contrast

Contrast With Local Dimming

The Samsung G9 has a VA panel, but its contrast ratio is only decent, so some blacks look gray in dark scenes. The local dimming doesn't seem to do much in SDR, as the contrast remains almost unchanged. Even when you enable it in HDR it causes large dimming zones to turn on, actually reducing the overall contrast with the checkerboard pattern, but blacks are deeper when the dimming zones are off.

Unfortunately, the local dimming is terrible. It has edge-lit local dimming and doesn't feature Mini LED backlighting like the Samsung Odyssey Neo G9. You can enable it in SDR, but it doesn't seem to do anything, and it only works properly in HDR. There are only 10 vertical lighting zones, so the entire column lights up if there's a small object anywhere on the screen. When lit, the black level rises significantly and there's distracting blooming, as there's a big difference between the zones that are lit and those that aren't. Zone transition seems to be faster in the middle than at the edges of the screen, so while the center zones react quickly to objects going in and out, the zones at the edges of the screen are almost always on. Overall, it looks better without local dimming in regular HDR content.

The color accuracy before calibration is mediocre. Even though it has an sRGB mode to lock the colors to the sRGB color space, some colors are still oversaturated. Also, the white balance is bad, especially with brighter whites and darker grays, and gamma doesn't follow the target curve at all, making most images appear too dark. The sRGB locks a few picture settings, including the Contrast, Color, and Black Level, but other modes have worse accuracy.

After calibration to the 6500K white point, the monitor has incredible color accuracy. The remaining inaccuracies shouldn't be visible to the naked eye, and the color temperature is almost right on the 6500K target. Gamma is significantly improved, but both dark and bright scenes are now slightly over-brightened. We encountered a bug during testing, causing our calibration settings to reset and return to the default values when changing the picture mode or other settings.

The monitor's variable refresh rate support only works over a DisplayPort connection and not at all over HDMI. There are also some minor issues of flickering with low frame rates in dark scenes with VRR enabled, which is typical of Samsung monitors like the Samsung Odyssey G7 C32G75T. Samsung has added a VRR Control setting to reduce the flicker through a firmware update. However, this also increases the input lag.

The Samsung Odyssey G9 has a good response time when running at its max refresh rate, resulting in only a short blur trail behind fast-moving objects. Enabling VRR locks you out of any of the overdrive settings, resulting in a ton of overshoot though. If you disable VRR, either 'Standard' or 'Faster' are good options as they have less overshoot.

The response time at 120Hz is great and there's actually less overshoot than at its max refresh rate. If you disable VRR and want to send a fix refresh rate, you need to also change the Refresh Rate in the on-screen display to 120Hz. In that case, the 'Standard' overdrive setting performs best because it has a quicker response time and less overshoot than 'Faster' and 'Fastest'.

The response time at 60Hz is decent, but there's more motion blur than with faster frame rates. If you disable VRR and set the OSD to 60Hz, the monitor seems to still work at 120Hz, so the 'Standard', 'Faster', and 'Fastest' results are all nearly the same as at 120Hz. Only if you send a 60Hz signal with VRR enabled does the screen refresh at a true 60Hz cycle.

PWM Dimming Frequency

The Samsung G9 uses pulse width modulation (PWM) to dim the backlight. It's flicker-free with the backlight set to anything above '0', and it flickers at over 2000Hz with the backlight at '0', which isn't noticeable.

Like other Samsung monitors, there are scanline issues that only affect certain content, and it isn't something you'll see during most usage. However, you can see an example of it here and it what it should normally look like here.

The Samsung Odyssey G9 has low input lag for a responsive feel, especially with high-frame-rate signals. However, if you have VRR disabled, you need to make sure the refresh rate in the on-screen display (OSD) matches the frame rate of the source; otherwise, the input lag increases. You can see the results with the different combination of settings, including enabling Adaptive Sync in the OSD below. The only exception is if you set the OSD to 240Hz and send a 60 fps fixed signal, you'll get lower input lag than if you were to set the OSD to 60Hz.

Additionally, enabling VRR Control causes the input lag to increase, from 2.8 ms to 10.7 ms with a 240Hz refresh rate.

The Samsung Odyssey G9 has a massive screen that's equivalent to two 27-inch, 16:9 screens placed side-by-side, delivering an immersive gaming experience, and providing plenty of space for multitasking. Note that not all games support a 32:9 aspect ratio, so you might get some black bars on the side, or the image might be stretched out to fill up the whole screen. If you find the 32:9 aspect ratio too big, then check out the Samsung Odyssey G5 C34G55T, which has a 21:9 aspect ratio.

The Samsung Odyssey G9 has limited compatibility with the PS5 as it doesn't support 120Hz games at all, and VRR doesn't work. Also, because the PS5 doesn't support ultrawide gaming, you'll see black bars on the sides.

Once again, the compatibility with the Xbox Series X is limited, but you can at least get a 1080p @ 120Hz signal by enabling the HDMI override. It accepts a 4k signal and downscales it, resulting in a sharper image than a native 1440p signal.

macOS Compatibility

The Samsung Odyssey G9 works well with macOS, but there are some limitations. It doesn't work with 240Hz signals unless you have your macOS updated to version 13.2, as you can see here, but the VRR works well regardless. The VRR always turns off when you close the lid, and the laptop going to sleep also sometimes disables HDR, so if that happens, you have to go back into the display settings to enable it again.
