Odyssey g7 t1 faker edition3/19/2023 ![]() ![]() We noticed a flicker-like effect when displaying this GIF. There have been reports of flicker with certain games, so we decided to look into it. The Samsung Odyssey G7 is flicker-free at all backlight settings, which helps reduce eye strain. ![]() Unfortunately, this solution also results in a very soft and blurry image. ![]() Adjusting the Sharpness reduces the issue, and setting it to '45' or lower eliminates it on our unit. We can reproduce the issue by displaying a specific test pattern. Update : We looked into the pixel inversion issue reported below again. It appears to vary between units, as there are multiple other confirmations of units that don't flicker, but your results could vary. The Samsung was tested in SDR, HDR, and with different games, but despite actively trying, we couldn't reproduce the issue. 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 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 dimmed a bit. We received reports that the backlight flickers with VRR enabled. G-SYNC only works over a DisplayPort connection. The Samsung Odyssey G7 has native FreeSync VRR support, and it's certified by NVIDIA to be G-SYNC compatible. This only happened to us after firmware update 1009.3 when Samsung added the VRR Control setting let us know if you experience the same issue. Update : Unfortunately, VRR doesn't appear to be functioning correctly with the refresh rate set to 60Hz. As all of these tests are consistent, we're confident in our measurements. 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. ![]() We also tried adjusting different settings to see if that made a difference. We did it with different equipment and even with a different way to measure contrast, but we obtained very similar results. Since the contrast measurements are quite a bit higher than Samsung's specifications for this display, we remeasured the contrast ratio. 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. It has a local dimming feature, but it doesn't improve the contrast ratio because the checkerboard test pattern keeps all the dimming zones on. The Samsung Odyssey G7 has a great contrast ratio, so it displays deep blacks, which is normal from a VA panel. Retested brightness, HDR color gamut, and HDR color volume. We've retested the image flicker with the latest firmware version 1009.3. We can replicate it, but we're not sure what the cause is. There are reports of issues when displaying a specific pattern at 1080p. We also rechecked the pixel inversion issue. We measured the response time with the VRR Control setting on and off at both the max response time and 60Hz. Added tests for Console Compatibility and macOS compatibility and made minor changes to other tests, which you can see in our Changelog. Updated to Test Bench 1.2, resulting in changes to the results and scores with the Response Time and Input Lag. We tested the monitor with the PS5's new variable refresh rate feature and confirmed that it's not compatible, since the PS5 only supports HDMI Forum VRR. We tested the monitor to confirm that it works with the PS5's new 1440p support. ![]()
