Samsung Odyssey G55T C27G55T  Monitor Review

The Samsung Odyssey G5 has a gamer-oriented design with an all-black body and a V-shaped stand. It has a ring in the back, but unlike other Samsung monitors, there isn't any RGB lighting. The curved screen is aggressive, and it's meant to bring the edges more within your field of vision.

This monitor's build quality is decent. It's entirely plastic, and it feels relatively sturdy overall. However, the screen seems too heavy for the stand as it tilts downwards at times, including when you VESA-mount it because the VESA screws aren't aligned with the center of the screen, causing it to tilt down. The stand feels cheap, and although it's easy to install, it's hard to remove.

Sadly, this monitor has terrible ergonomics. It only allows for a narrow tilt adjustment, so it's hard to place it in an ideal viewing position. If you want something with much better ergonomics, look into the Samsung Odyssey G3 F27G35T.

The back is made out of textured plastic. All the inputs are bottom-facing, and they're hard to reach with the screen mounted. There's a passthrough on the stand for cable management.

The stand's feet are wide-set, but they're relatively thin, leaving you a good amount of usable desk space. Unfortunately, it's a very basic stand made out of cheap plastic, and it wobbles quite a bit.

There's a single joystick located just below the Samsung branding at the center of the bottom bezel. It allows you to turn the monitor On/Off and navigate the monitor's on-screen menu.

This monitor has a good contrast ratio, so blacks look black next to bright highlights, but it doesn't have a local dimming feature to further improve it.

The Samsung G5 doesn't have a local dimming feature. We still film these videos on the monitor so you can compare the backlight performance with a monitor that has local dimming.

The Samsung G5 has decent SDR peak brightness. Except for the dimmer 2% window caused by frame dimming, brightness is very consistent across different scenes. However, it isn't bright enough to overcome intense glare, so it's better suited for a dark to moderately-lit room.

These results are from after calibration in the 'Custom' Picture Mode, with Brightness set to max.

This monitor has disappointing HDR peak brightness. It isn't bright enough to make highlights stand out in HDR content, and just like in SDR, the 2% window is dimmer, meaning small highlights don't stand out. Unfortunately, the EOTF doesn't follow the target PQ curve very well either, as most scenes are too dark until there's a sharp roll-off at the peak brightness, causing a loss of fine details.

These results are from the 'Custom' Picture Mode, with Brightness set to max.

The horizontal viewing angle is sub-par. The image looks inaccurate when viewed from the side, which isn't ideal for co-op gaming or sharing content. However, the curved screen helps bring the edges more within your field of vision, so the edges look the same as the rest of the screen.

Unfortunately, this monitor has a poor vertical viewing angle. This causes the screen to look washed out if you have the monitor mounted above or below eye level.

The Samsung Odyssey G5 27 has excellent gray uniformity. It's a little darker on the right edge of the screen, but thankfully, it isn't that noticeable, and there's almost no visible dirty screen effect.

Unfortunately, the black uniformity is bad. There's a lot of backlight bleed along the top and bottom edges of the screen, making the entire screen look gray.

This monitor has fantastic accuracy in SDR before calibration. Although it doesn't have an sRGB mode to clamp the colors to the sRGB color space, only a few colors are slightly oversaturated, which you might notice when browsing web content that uses the color space. The white balance is also great. Unfortunately, the color temperature is on the warm side, resulting in a red tint, and gamma doesn't follow the target curve well, meaning most scenes are too bright.

This monitor has exceptional accuracy after calibration to the 6500K white point. The white balance is nearly perfect, and gamma follows the sRGB target curve nearly perfectly. Most colors are accurate, and the color temperature is extremely close to the target.

The Samsung Odyssey G5 27 has a good SDR color gamut. It has great coverage of the sRGB color space used in most content but limited coverage of the Adobe RGB color space, which isn't ideal for professional content creators who require this color space.

This monitor has good SDR color volume. It can display dark colors relatively well, but it has trouble producing bright colors.

Although the monitor supports HDR, it can't display a wide color gamut. It has mediocre coverage of the commonly-used DCI-P3 color space and poor coverage of the wider Rec. 2020.

The HDR color volume is bad, mainly due to its limited color gamut and low brightness. It has difficulty displaying bright colors as well as very dark and saturated colors.

The reflection handling is very good. Its matte anti-reflective coating does a good job of diffusing bright reflections; however, visibility can still be an issue in well-lit environments due to the monitor's low brightness.

The text clarity is decent. Windows ClearType (top photo) helps with diagonal lines, like on the R and N, but it can make vertical lines look slightly thinner. The text clarity is likely worse on the 32-inch model due to its lower pixel density.

This monitor has superb gradient handling. There's a tiny amount of banding in the darker shades of gray, red, and green, but it isn't noticeable in most content.

Due to bandwidth limitations, the max refresh rate is limited when you send a 10-bit signal, so you need to send an 8-bit signal to get full use of this monitor, but that results in more banding. If you want something with a higher 165Hz refresh rate, check out the MSI Optix G27CQ4.

The Samsung G5 Odyssey supports FreeSync natively to reduce screen tearing. Although not officially certified by NVIDIA, it also works with their G-SYNC Compatible feature, but only over DisplayPort.

The response time at its max refresh rate is bad. Most transitions are slow, resulting in black smearing with fast-moving objects. When you enable the VRR feature, you can't use any of the Response Time settings. If you don't use FreeSync, 'Faster' has a quicker response time without introducing overshoot. If you want something similar with better motion handling, you can also check out the Samsung Odyssey G5/G51C S27CG51.

The response time at 120Hz is once again bad. Enabling FreeSync results in noticeable smearing with fast-moving objects, but if you disable it, the 'Faster' Response Time setting results in better motion.

The response time at 60Hz is terrible, and the smearing is even worse than with the higher refresh rates. If you want better motion handling, you'll have to disable the VRR and use the 'Faster' Response Time setting, which has faster overall transitions, but there's still motion blur.

The monitor has an optional backlight strobing feature, commonly called black frame insertion, to improve motion clarity. Because it only flickers at 144Hz, there's noticeable image duplication with lower frame rate signals. When enabled, the screen becomes noticeably darker, and it remains active as long as you don't adjust the screen's brightness. It sometimes causes the screen to dim so much that we can barely navigate the on-screen menu, and we could only get the brightness to return to normal after unplugging the monitor.

The backlight is flicker-free when the backlight is set above 0; however, there's a 144Hz flicker when the backlight is at 0, which matches the monitor's refresh rate. If flicker bothers you, the Dell S2722DGM is a similar monitor that's completely flicker-free. The replacement for this model, the Samsung Odyssey G5/G55A S27AG55, doesn't have this issue with flicker.

The monitor has very low input lag for a responsive feel. However, like other Samsung monitors, the input increases when you disable the VRR, and there's a mismatch between the refresh rate in the on-screen display and the input source's frame rate. Essentially, you just need to make sure to set the monitor's refresh rate to the same frame rate as your source if you aren't using VRR.

The 32-inch variant is better for multitasking if you prefer the larger screen but has lower pixel density. The 34-inch variant has a 21:9 aspect ratio and a 3440x1440 resolution for similar pixel density as this monitor.

The monitor works well with the PS5, but due to bandwidth limitations, it can't take full advantage of it for 4k @ 120Hz gaming. It downscales a 4k image, which results in a sharper image than a native 1440p signal too.

This monitor works well with the Xbox Series X for signals up to 4k @ 60Hz. It downscales a 4k image, but there are limitations as you have to disable VRR and the color temperature is different than when sending a 1440p signal.

For the most part, this monitor works well with MacBooks. There are no issues waking up from sleep, it responds quickly, and windows are restored to their original position. VRR doesn't work properly on the desktop, though, and in-game, it only works well if your computer can maintain a high frame rate. At low frame rates, it flickers considerably and doesn't look very good.

The monitor has only a few extra features. You can add a virtual crosshair, and there's an Eye Saver Mode to help reduce eye strain.
