The Samsung Odyssey G5 LC34G55T is a great gaming monitor. It's an ultrawide variant of the Samsung Odyssey G5 LC27G55T with a 21:9 aspect ratio and 3440x1440 resolution for a more immersive gaming experience. It's a great choice for dark room gaming thanks to its high contrast ratio, allowing it to display deep blacks. It has a 165Hz refresh rate, native FreeSync variable refresh rate (VRR) support, and quick response time. Input lag is extremely low, but unfortunately, there are a ton of bugs that cause the input lag to increase and VRR to stop working. Also, it's not good for sharing your screen with others as it has narrow viewing angles, and the stand only allows for limited tilt adjustments. It supports HDR10 but doesn't deliver a true HDR experience due to its low HDR peak brightness and lack of a wide color gamut.
The Samsung Odyssey G5 34 is good for mixed usage. It's great for gaming because it has a high 165Hz refresh rate with a quick response time. Input lag is low, but some bugs cause it to increase. Its 34 inch screen and 1440p resolution make it decent for office use, but it has terrible ergonomics and narrow viewing angles. Sadly, HDR content doesn't look anything special as it can't display a wide color gamut and has mediocre HDR peak brightness.
The Samsung Odyssey G5 34 is decent for office use. The 34 inch screen and 1440p resolution allow you to open multiple windows side-by-side and deliver clear images. It also has decent peak brightness and good reflection handling. Sadly, it has terrible ergonomics and narrow viewing angles, making it less-than-ideal for sharing your screen with others around you.
The Samsung Odyssey G5 34 is great for gaming. It has a high 165Hz refresh rate with a quick response time that results in smooth motion with fast-moving content. It has low input lag, but there are a ton of bugs with the monitor that cause the input lag to increase and VRR to stop working. On the upside, it has an excellent native contrast ratio to display deep blacks, great for dark room gaming.
The Samsung Odyssey G5 34 is good for consuming media. The large screen and high resolution help deliver an immersive viewing experience. It also has an excellent native contrast ratio, which is great for watching movies in the dark. Sadly, it has narrow viewing angles, so the image looks inaccurate when viewing from the side.
The Samsung Odyssey G5 34 is decent for content creators. Its 34 inch screen allows you to see more of your work, like your video timeline, and it has a high 1440p resolution. Unfortunately, it's a bit difficult to share your screen with coworkers and clients as it has terrible ergonomics and narrow viewing angles.
The Samsung Odyssey G5 34 is decent for HDR gaming. Its high 165Hz refresh rate, quick response time, and low input lag help deliver a great gaming experience. Despite having an excellent native contrast ratio, it fails to deliver a true HDR experience as it has low HDR peak brightness and can't display a wide color gamut.
The Samsung Odyssey G5 34 looks exactly like the Samsung Odyssey G5 LC27G55T, just in an ultrawide format. It has an all-black body made with basic plastic. It doesn't look as premium as the Samsung Odyssey G7 as it comes with a different, less-ergonomic stand. Although it's a gaming monitor, it shouldn't stand out in an office environment.
The V-shaped stand is wide enough to leave room so you can still place stuff in front of it. The plastic stand feels cheap and attaches to the monitor with basic clips.
Sadly, the Samsung G5 34's ergonomics are terrible. It only allows for limited tilt adjustment, and even at that, it's difficult to tilt the screen upwards. If you want an ultrawide monitor with better ergonomics, check out the Dell UltraSharp U4021QW.
Due to the aggressive curve of the screen, the Samsung Odyssey G5 34 is thicker than most monitors, so you need a deep desk to place it on.
The Samsung C34G55T has okay build quality. It's made of basic-feeling plastic, and the stand feels cheaply-made. VESA holes are visible on the back and they aren't centered. You also need a lot of force to tilt the screen upwards. Overall, even though there's nothing wrong with it and nothing is falling off, there isn't anything premium about it either.
The Samsung G5 Odyssey 34 has an excellent native contrast ratio. It displays deep blacks when viewed in the dark, which is expected from a VA panel. It's much higher than the Samsung Odyssey G5 LC27G55T, but this is something that varies between units. We also noticed the Samsung Odyssey G7 has a higher contrast than advertised, but again, this can vary from unit to unit.
The contrast is much higher than the advertised 2500:1, but we verified that this is correct. While we first measured it with our regular checkboard pattern method, we also measured it with full black and full white screens and received similar results. We then repeated the tests with different test equipment, and again got similar numbers. We measured the contrast of the monitor after calibration using the following settings:
If you have this monitor and notice a lower contrast ratio, let us know.
The Samsung G5 34 doesn't have a local dimming feature. The video above is provided for reference only.
The Samsung Odyssey G5 34 has decent SDR peak brightness. It's a bit higher than the advertised 250 cd/m², and it remains extremely consistent across different content. Although it may not be enough to combat glare in a very well-lit room, it should be good enough for moderately-lit or dim rooms. We tested the SDR peak brightness after calibration in the 'Custom' Picture Mode. If you need a similar monitor that gets brighter, check out the ASUS TUF Gaming VG34VQL1B.
The Samsung G5 34's HDR peak brightness is mediocre. It gets a bit brighter than in SDR, but it's not enough to truly make highlights stand out the way the creator intended. Unlike the Samsung Odyssey G5 LC27G55T, small highlights don't get dimmer as brightness remains consistent with different content. When you enable the HDR setting, it locks you out of any picture mode settings.
The horizontal viewing angle is disappointing, which is expected from a VA panel. The image looks inaccurate when viewing from the side, so it's not the best for co-op gaming.
Like with the horizontal viewing angle, the Samsung G5 34's vertical viewing angle is disappointing. You lose image accuracy if you mount the screen above eye-level.
The Samsung C34G55T's gray uniformity is excellent. There aren't any signs of dirty screen effect in the center and uniformity is even better in near-dark scenes. Keep in mind that gray uniformity may vary between units.
The Samsung G5 34 has okay black uniformity. There's noticeable backlight bleed along the top and bottom edges. It's hard to tell in the cropped picture, but the backlight bleed is more noticeable on the left side, as you can see in the local dimming video.
Our Samsung G5 34 has amazing out-of-the-box accuracy, but this can vary from unit to unit. Any white balance and color inaccuracies are hard to spot. Gamma follows the sRGB curve fairly well, but bright scenes are brighter than they should be. The color temperature is colder than our 6500K target, resulting in a blue tint.
After calibration, the Samsung G5 34's accuracy is remarkable. There are even fewer color and white balance inaccuracies. Gamma improved, but some really bright scenes are still too bright. Fortunately, the color temperature is extremely close to the target.
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 G5 34's SDR color gamut is excellent. It has near-perfect coverage of the commonly-used sRGB color space. It also has good coverage of the Adobe RGB color space used in photo editing.
The SDR color volume is fantastic. It displays colors at a wide range of luminance levels, but it still has some trouble with really bright colors.
The Samsung Odyssey G5 34 has an okay HDR color gamut, but it's not considered a wide color gamut for HDR content. It has good coverage of the DCI P3 color space used in most content, but its coverage of the wider Rec. 2020 is disappointing.
The Samsung G5 Odyssey 34 has a disappointing HDR color volume, mainly limited by its lack of a wide color gamut. It has trouble displaying really bright colors.
Our unit of the Samsung Odyssey G5 34 shows no signs of temporary image retention, but this can vary between units.
The Samsung G5 34 has remarkable gradient handling. You shouldn't notice any banding in most content.
There are no visible signs of color bleed on the Samsung Odyssey G5 34.
The Samsung C34G55T has good reflection handling. It shouldn't be an issue if there's a moderate amount of light on the screen, but it struggles in really bright rooms as the reflections are stretched across the screen.
Text clarity on the Samsung G5 Odyssey 34 is good. Enabling Windows ClearType (top photo) slightly improves the appearance of diagonal lines, like on R and G, but makes straight lines a bit thinner.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The Samsung G5 34 has a very good response time at its max refresh rate of 165Hz. Its total response time is on the slower side, especially in dark transitions, so you may notice motion smear in dark scenes. The recommended overdrive setting is 'Fastest' because it has the quickest response time, but as you can see in the photo above, there's still some motion blur trail.
|Overdrive Setting||Response Time Chart||Response Time Tables||Motion Blur Photo|
The response time at 60Hz of the Samsung G5 34 is great, even better than the Samsung Odyssey G5 LC27G55T. It has a quicker total response time than the other settings, but once again, the response time in dark transitions is slow. Like with its response time at 165Hz, the recommended overdrive setting is 'Fastest'. Also, there's the most overshoot with this setting, so you still may notice motion blur.
The Samsung Odyssey G5 34 has a flicker-free backlight, which helps reduce eye strain, and helps eliminate image duplication in fast-moving content.
The Samsung G5 Odyssey 34 has a Black Frame Insertion feature, but it only flickers at 165Hz, no matter what the refresh rate is set at. If you set the refresh rate in the monitor's on-screen display (OSD) to anything other than 165Hz, it completely disables the BFI setting. If you change the refresh rate through your PC's settings instead, you can enable the BFI setting, but it only flickers at 165Hz. Note that the BFI score is based on the range at which the BFI works, and not its actual performance.
The Samsung G5 34 has a high 165Hz refresh rate with native FreeSync support, and it's also G-SYNC compatible. However, we ran into some issues with the refresh rate and VRR. If you set your PC's refresh rate to 60Hz and enable FreeSync in the monitor's OSD, VRR doesn't work properly and there's screen tearing throughout. However, if you set both the monitor's and PC's settings to 165Hz, there aren't any VRR issues throughout the entire refresh rate range.
Also, if you set the monitor's refresh rate to 120Hz, there aren't any issues with VRR. However, if you set it to 100Hz, VRR only works between 60-100Hz. The max refresh rate over HDMI is 100Hz, and FreeSync doesn't work at all over HDMI; we confirmed with our Xbox Series X and it showed VRR as incompatible with the monitor.
Another anomaly that we encountered is when turning off FreeSync in the OSD, G-SYNC was still enabled in the NVIDIA Control Panel. Normally, if FreeSync is enabled in the OSD, we don't have access to the response time and refresh rate settings on the monitor, but with G-SYNC enabled in the Control Panel, we had access to those settings on the monitor. We also confirmed that G-SYNC works properly, but once we enabled FreeSync and disabled it again, G-SYNC was also disabled in the Control Panel.
Essentially, if you plan on using VRR, make sure your refresh rate setting on the monitor is 120 or 165Hz; otherwise, it won't work properly. If you have this monitor and experience the same issues, let us know.
