The Samsung Odyssey G7 is a versatile monitor with amazing gaming performance that's available either in a 27 or 32 inch size. It has a fast 240Hz refresh rate and an outstanding response time, resulting in exceptionally clear motion. It supports FreeSync variable refresh rate (VRR) technology and it's certified by NVIDIA to be G-SYNC compatible too. Its picture quality is very good as it has a great contrast ratio, good out-of-the-box color accuracy, and an outstanding color gamut. Sadly, it has narrow viewing angles because of its VA panel, so you quickly lose image accuracy when viewing from the side. Also, it's a well-built monitor, but its aggressive 1000R curve might not be to everyone's liking. Additionally, it's packed with extra features like a Picture-in-Picture/Picture-by-Picture mode and RGB illumination.

Our Verdict

8.1 Mixed Usage

The Samsung Odyssey G7 is a great overall monitor. It has amazing gaming performance because of its 240Hz refresh rate, outstanding response time, and it has FreeSync support too. It's a good choice for content creators or for watching movies as it's able to display deep blacks. Unfortunately, it's not ideal for sharing your screen with coworkers due to its narrow viewing angles.

Pros
  • Outstanding response time.
  • Native FreeSync support and it's G-SYNC compatible.
  • Great contrast ratio.
  • Exceptional gradient handling.
Cons
  • Doesn't get very bright in HDR.
  • Narrow viewing angles.
  • Limited swivel and tilt range.
7.7 Office

The Samsung Odyssey G7 is good for office use. It has a large, 32 inch screen with a 1440p resolution, giving you enough screen space to multitask. Sadly, because of its VA panel, it has narrow viewing angles, which isn't ideal for sharing your screen with others. On the upside, it gets bright enough to combat glare and it has very good reflection handling.

Pros
  • Very good reflection handling.
  • Exceptional gradient handling.
  • Great text clarity.
Cons
  • Narrow viewing angles.
  • Limited swivel and tilt range.
8.8 Gaming

The Samsung Odyssey G7 is amazing for gaming. It has a native 240Hz refresh rate, FreeSync support, and it's compatible with NVIDIA's G-SYNC. The response time at its max refresh rate and at 60Hz are both outstanding, resulting in minimal blur. Its narrow viewing angles make it less ideal for co-op gaming, but luckily, it displays deep blacks if you want to game in the dark. We received reports of the backlight flickering with VRR enabled, but we didn't notice any flicker; rather the screen dims when a certain image is displayed full-screen.

Pros
  • Outstanding response time.
  • Native FreeSync support and it's G-SYNC compatible.
  • Great contrast ratio.
  • Incredibly low input lag.
Cons
  • Narrow viewing angles.
7.9 Multimedia

Very good for multimedia consumption. The Samsung Odyssey G7 has a big 32 inch screen and it has a high 1440p resolution. Unfortunately, you won't be able to watch the latest videos with a big group of friends since it has narrow viewing angles. However, it's a great choice for watching movies in a dark room because it displays deep blacks thanks to its VA panel.

Pros
  • Great contrast ratio.
  • Impressive coverage of the Adobe RGB color space.
  • Exceptional gradient handling.
Cons
  • Narrow viewing angles.
  • Limited swivel and tilt range.
8.0 Media Creation

The Samsung Odyssey G7 is great for media creation. Its 32-inch screen allows you to open multiple windows at once without having to scroll too much. However, the screen's aggressive curve may not be to everyone's liking while photo editing. Fortunately, it has impressive coverage of the Adobe RGB color space.

Pros
  • Great contrast ratio.
  • Impressive coverage of the Adobe RGB color space.
  • Exceptional gradient handling.
Cons
  • Narrow viewing angles.
  • Limited swivel and tilt range.
7.8 HDR Gaming

The Samsung Odyssey G7 is good for HDR gaming, mainly due to its amazing gaming performance. It has a 240Hz refresh rate, FreeSync support, an outstanding response time, and incredibly low input lag. Sadly, HDR content doesn't look all that different from SDR because it doesn't get bright enough in HDR to truly bring out highlights.

Pros
  • Outstanding response time.
  • Native FreeSync support and it's G-SYNC compatible.
  • Great contrast ratio.
  • Incredibly low input lag.
Cons
  • Doesn't get very bright in HDR.
  • Narrow viewing angles.

The back of the Samsung Odyssey G7 27 inch monitor has a textured plastic on it and there's RGB lighting on a ring where the stand is attached to the back. There's a headphone hook and the monitor can be VESA-mounted too. Cable management is serviced through the stand. The plastic cover comes off so you can place the cables through the stand, keeping your setup clean.

Build Quality

The Samsung Odyssey G7 has a great build quality. It's made out of good quality plastic that feels solid. The curve doesn't appear uniform throughout as it seems more curved in the center than at the sides, but overall, there aren't any obvious issues with this monitor.

Contrast
Native Contrast
3912 : 1
Contrast With Local Dimming
3913 : 1

Update 08/06/2020: As our contrast measurements are quite a bit higher than other reviewers have found, and even Samsung's specifications for this display, we remeasured the contrast ratio. We remeasured the contrast with different equipment, and even with a different way to measure contrast, but we obtained very similar results.

We also tried adjusting different settings to see if that made a difference. With 'Black Equalizer' at 10, we measured a contrast ratio of 3922:1, at 13 it was 3935:1, and at 20 it was 3892:1, so it's not much different from our original numbers. As all of these tests are consistent, we're confident in our measurements. Given that other reviews have found much lower contrast, there seems to be a significant variance in contrast between different units.

The Samsung Odyssey G7 has a great contrast ratio, so it displays deep blacks, which is expected from a VA panel. It has a local dimming feature, but it doesn't improve the contrast ratio at all because the checkerboard test pattern keeps all the dimming zones on. Note that this contrast ratio is much higher than Samsung's advertised 2500:1 contrast, and there appears to be significant variance in contrast between units.

There's a local dimming feature, but like most monitors, it's not very effective. There are only a handful of vertical dimming zones and the zone transitions are very visible when each zone lights up. This causes uniformity issues, especially in the test pattern, but it isn't as distracting in real content because the algorithm doesn't seem as aggressive as the one on the Samsung CHG70.

Update 08/17/2020: There was a mistake in our original testing and we retested SDR peak brightness with local dimming on to remain consistent with all monitors. We also retested 7 other monitors, and some results changed.

The Samsung Odyssey G7 has great SDR peak brightness, similar to the Samsung CHG70. It gets bright enough to combat glare, but it's not very consistent with varied content, so large, bright areas of the screen don't get very bright. We tested the peak brightness after calibration with local dimming on and brightness set to its max, and we were able to get the brightest image possible with these settings, as seen in the 2% peak window test.

08/06/2020: Retested the peak brightness with local dimming on. We also tested the peak brightness according to VESA's standards, and we were able to get a peak brightness of 558 nits in the 10% peak window test, which is close to the advertised 600 nits. However, it quickly dropped to 484 nits. The values and text have been updated to reflect these changes. We also retested 7 other monitors, and some results changed.

Just okay HDR peak brightness for the Samsung Odyssey G7. Small highlights are bright enough to stand out a bit, but most scenes aren't bright enough for most HDR content.

The Samsung Odyssey G7 has an outstanding response time at its max refresh rate of 240Hz. Motion looks exceptionally smooth and there's almost no blur. The recommended overdrive setting is 'Faster' because it has less overshoot than the 'Fastest' setting. Also, it has a slow response time in dark scenes, as seen in the 0-20% total response time, which causes some artifacts. This monitor's response time is almost as good as some other 240Hz monitors with an IPS panel, like the Dell Alienware AW2720HF.

Update 08/06/2020: We noticed a flicker-like effect when displaying this GIF. It changes the brightness of the screen and causes horizontal lines to appear, and when we close the GIF, this effect stops and the screen returns to normal. We weren't able to replicate the flicker some people have experienced in games (see Refresh Rate) without knowing the exact game and settings used that caused this flicker-like effect. However, we did notice this effect with Local Dimming on, as it seems the backlight turns itself on and off a few times. We also noticed the dimming zones flicker a bit during our Brightness tests. If you experience this issue, let us know in the comments below.

The Samsung Odyssey G7 is flicker-free at all backlight settings, which helps reduce eye strain. There have been reports of flicker with certain games, but we haven't been able to reproduce this issue the way some people have seen it.

The Samsung Odyssey G7 has an outstanding refresh rate. It has native FreeSync VRR support and it's certified by NVIDIA to be G-SYNC compatible. G-SYNC only works over a DisplayPort connection and the refresh rate over HDMI is limited to 144Hz.

We received reports that the backlight flickers with VRR enabled. We displayed a test photo that reportedly causes this flicker with VRR enabled, and when the image was displayed full-screen, the brightness of the screen dims a bit. It did the same thing without VRR enabled, and when the image was at any other size than 100% scaling, the brightness went back up. We tested this in SDR, HDR, and with different games, but despite actively trying, we weren't able to reproduce the issue. This appears to vary between units, as there are multiple other confirmations of units that don't flicker, but your results could vary.
