The Samsung Odyssey G5 C34G55T is a very good gaming monitor. It's an ultrawide variant of the Samsung Odyssey G5 C27G55T with a 21:9 aspect ratio and 3440x1440 resolution. 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 and native FreeSync variable refresh rate (VRR) support. 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.

Popular Monitor Comparisons
The Samsung Odyssey G5 34 is a very good gaming monitor with a 165Hz refresh rate and native FreeSync support. However, there are too many bugs that cause an increase in input lag or its VRR to stop working. Its motion handling is also mediocre with fast-moving objects, as they look blurry. There are other similarly-priced options that will save you some headaches, like the Gigabyte G34WQC.
See our recommendations for the best ultrawide monitors, the best gaming monitors, and the best 1440p monitors.
The Gigabyte G34WQC and the Samsung Odyssey G55T C34G55T 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.
The ASUS TUF Gaming VG34VQL1B and the Samsung Odyssey G55T C34G55T are very similar as they're both 34-inch ultrawide monitors with a VA panel, a 3440x1440 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.
The Samsung Odyssey G55T C34G55T and the AOC CU34G2X are both great gaming monitors. The Samsung has a higher 165Hz refresh rate compared to 144Hz on the AOC. 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.
The Samsung Odyssey G55T C34G55T is a larger variant of the Samsung Odyssey G55T C27G55T 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.
We buy and test more than 30 monitors each year, all of which we purchase ourselves, without cherry-picked units or samples. We put a lot into each unbiased, straight-to-the-point review, and there's a whole process from purchasing to publishing, involving multiple teams and people. We do more than just use the monitor for a week; we use specialized, custom tools to measure various aspects and deliver objective, data-driven results. We also consider multiple factors before making any recommendations, including the monitor's cost, its performance compared to the competition, and whether it's easy to find.
