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.

Our Verdict

7.5 Mixed Usage

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.

Pros
  • Large 34 inch screen and 3440x1440 resolution.
  • 165Hz refresh rate with native FreeSync support.
  • Quick response time.
  • High contrast ratio to display deep blacks.
Cons
  • Stand only allows for limited tilt adjustment.

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.

Pros
  • Large 34 inch screen and 3440x1440 resolution.
  • Decent SDR peak brightness and good reflection handling.
Cons
  • Narrow viewing angles.
  • Stand only allows for limited tilt adjustment.
7.1 HDR Gaming

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.

Pros
  • 165Hz refresh rate with native FreeSync support.
  • Low input lag.
  • Quick response time.
  • High contrast ratio to display deep blacks.
Cons
  • Bugs causes issues with input lag and VRR.
  • FreeSync doesn't work over HDMI.

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.

Build Quality

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:

  • Picture Mode: Custom
  • Brightness: 21
  • Contrast: 70
  • Sharpness: 60

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 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. If you want an ultrawide gaming monitor with a faster response time, check out the Dell S3422DWG.

Update 08/20/2021: We retook the response time measurements at 60Hz, as we noticed that there was a frame duplication issue with the data. This duplication was caused by sending a 60Hz signal with the Refresh Rate setting set to '165Hz' in the monitor's OSD. We took new measurements with the setting set to '60Hz'. The frame doubling issue appears to be an intermittent bug, as unplugging the PC and resetting the monitor eliminates the issue, and there's no frame doubling regardless of the setting used. Unfortunately, the response time performs significantly worse with this setting set to '60Hz' with a 60Hz source.

The response time at 60Hz of the Samsung G5 34 is decent. Unlike at the max refresh rate, we recommend the 'Standard' Overdrive setting. At 60Hz, the 'Faster' setting has much more noticeable overshoot. This is disappointing, as you'll need to remember to change the overdrive setting when changing refresh rates from the source, like if you start playing a game with a capped refresh rate.

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.

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.

The Samsung Odyssey G5 34 has extremely low input lag, and it only increases slightly with VRR enabled at max refresh rate, which is great. However, we encountered multiple issues when testing for 60Hz input lag, which are listed below:

  • Originally, we measured an input lag of 22.6 ms at 60Hz, which seems too high. The monitor's refresh rate in the OSD was set to 165Hz, while the PC's refresh rate was set to 60Hz, and VRR was disabled. We tried again by setting the monitor's refresh rate to 60Hz and obtained a result of 9.4 ms, which is more reasonable. However, we tried again with the monitor set to 100Hz and measured 26.8 ms. We also tried sending a 1080p @ 60Hz signal and measured 16.8 ms. So to get the lowest input lag at 60Hz, you need to set the monitor and the PC to 60Hz, and the resolution has to be 1440p.
  • As for the input lag at 165Hz, it can be inconsistent at times too. After measuring for 60Hz input lag and noticing its multiple issues, we retested the input lag at 165Hz, and initially got 8.7 ms, which is outside of the margin of error of the original 4.0 ms measurement. We changed the refresh rate in the OSD to 60Hz then back to 165Hz and got 7.9 ms. Only after resetting the monitor and the DisplayPort handshake, we achieved 4.1 ms, which is an acceptable result.
  • As mentioned in the Refresh Rate section, 60Hz VRR doesn't work properly, so we had issues measuring the input lag. With FreeSync disabled in the OSD and G-SYNC enabled in the NVIDIA Control Panel, we measured the 60Hz VRR input lag and got 10.8 ms. However, this bug isn't normal and we don't expect most people to have the same issue; we weren't able to recreate it once we enabled and disabled FreeSync again. We left 60Hz VRR input lag as N/A because we couldn't get FreeSync VRR to properly work and we don't expect most people to play around with the settings like this.
  • Lastly, we didn't measure the 10-bit HDR input lag because the max 10-bit refresh rate over HDMI is 100Hz. You can reach 120Hz over a DisplayPort connection, but we don't have the tools necessary to measure HDR input lag over DP.

Compared To Other Monitors

The Samsung Odyssey G5 34 is a great gaming monitor with a 165Hz refresh rate and native FreeSync support. However, we experienced too many bugs at the time of writing with its VRR support and with input lag increasing. There are other similarly-priced options that will save you some headaches, like the Gigabyte G34WQC. Also see our recommendations for the best ultrawide monitors, the best gaming monitors, and the best 1440p monitors.

Samsung Odyssey G7 LC32G75T

The Samsung Odyssey G7 LC32G75T is much better overall than the Samsung Odyssey G5 LC34G55T. The G7 is available in both 27 and 32 inches and has a 16:9 aspect ratio. It has a higher 240Hz refresh rate, a much faster response time, and its Black Frame Insertion feature flickers at a much wider range than on the G5. The G7 also has a local dimming feature, which the G5 doesn't have, but it doesn't add much because it performs terribly. On the other hand, the 34 inch G5 is larger and has a 21:9 aspect ratio, so there's more space to open multiple windows side-by-side.

Gigabyte M27Q

The Gigabyte M27Q and the Samsung Odyssey G5 LC34G55T are very different monitors. The Gigabyte has a 27 inch IPS panel with a 16:9 aspect ratio, while the Samsung has a 34 inch VA panel with a 21:9 aspect ratio. For the most part, the Gigabyte performs better. It has a faster response time that results in a clearer image with less smearing behind fast-moving objects. It also has wider viewing angles, gets brighter, and offers more features, like USB-C input. The Samsung is better for dark rooms because it can produce deeper blacks, and its wider format might feel more immersive for some people.

Gigabyte G34WQC

The Gigabyte G34WQC and the Samsung Odyssey G5 LC34G55T are two great gaming monitors. They both have a VA panel with a high contrast ratio but narrow viewing angles. The Samsung has a more aggressive curvature than the Gigabyte, but that comes down to personal preference. The Gigabyte is better for HDR content because it displays a wide color gamut and gets brighter. Also, it has a better stand as it allows for height adjustment. The Samsung has a higher 165Hz refresh compared to 144Hz on the Gigabyte, but overall, they deliver similar gaming performance.

ASUS TUF Gaming VG34VQL1B

The ASUS TUF Gaming VG34VQL1B and the Samsung Odyssey G5 LC34G55T are very similar as they're both 34 inch ultrawide monitors with a VA panel, a 3440 x 1440 resolution, and a 165Hz refresh rate. Gaming-wise, the ASUS performs better because it has significantly faster response times, and it isn't as buggy as the Samsung when it comes to VRR and input lag. Also, it has higher peak brightness in SDR and HDR, and its stand offers more ergonomic adjustments.

Dell S3422DWG

The Dell S3422DWG is better than the Samsung Odyssey G5 LC34G55T. The Dell has better ergonomics, slightly better viewing angles, and a much faster response time, despite the Samsung's higher refresh rate. The Samsung has better contrast, but the Dell has much better black uniformity. There's also a slight design difference, as the Samsung has a more pronounced curve, which might bother some people.

Gigabyte G32QC

The Gigabyte G32QC and the Samsung Odyssey G5 LC34G55T are very similar overall, with the main difference being that the Gigabyte is a 27 inch model with a 16:9 aspect ratio, while the Samsung is a 34 inch ultrawide with a 21:9 aspect ratio. The Samsung has a much better contrast ratio to produce deeper blacks, making it a better option for dark rooms, but the Gigabyte is better for well-lit rooms because it gets a lot brighter to combat glare. The Gigabyte is also better for viewing HDR content because it has a wider color gamut and higher peak brightness to make highlights stand out.

Samsung Odyssey G5 LC27G55T

The Samsung Odyssey G5 LC34G55T is a larger variant of the Samsung Odyssey G5 LC27G55T with a 34 inch screen and 21:9 aspect ratio. The 27 inch version is also available in a 32 inch size, and they each have a 16:9 aspect ratio. Each variant has mainly the same features and design, but the 34 inch variant has a DisplayPort 1.4 input, allowing it to produce a higher 165Hz refresh rate. We encountered a lot of bugs with VRR and input lag on the 34 inch model that we didn't see on the 27 inch model, but your experience may vary.

AOC CU34G2X

The Samsung Odyssey G5 LC34G55T and the AOC CU34G2X are both great gaming monitors. The Samsung has a higher 165Hz refresh rate compared to 144Hz on the AOC, and while the Samsung has native FreeSync support, which the AOC doesn't have, FreeSync still works on it. The Samsung is a bit better to use in a well-lit room because it has better reflection handling and gets a bit brighter. It also has a much higher contrast, but this can vary between units. On the other side, the AOC has many more ergonomics adjustments, as you can swivel it and adjust the height, which you can't do on the Samsung.

LG 34GN850-B

The LG 34GN850-B is better overall than the Samsung Odyssey G5 LC34G55T, but they have different panel types. The LG has an IPS panel with wide viewing angles, while the Samsung has a VA panel with a higher contrast ratio. The LG is a bit better for gaming because it has a much quicker response time that results in smoother motion, and it gets brighter overall than the Samsung, making it a better choice for HDR gaming.

Nixeus EDG 34

The Samsung Odyssey G5 LC34G55T is a better monitor overall than the Nixeus EDG 34. They each have a VA panel with a high contrast ratio, and each of their stands offer terrible ergonomics. They have similar gaming performance, but we experienced a lot of bugs with the Samsung that caused its input lag to increase and VRR to stop working. The Samsung also has a higher 165Hz refresh rate than the 144Hz on the Nixeus.
