![]() ![]() ![]() We experienced the problem with our NVIDIA RTX 3070 and AMD RX 6800 graphics cards.Īdditionally, it stretches images very slightly horizontally, as square images are about 2.5% wider horizontally. This problem is only noticeable with high-frame-rate signals like 4k 144Hz 10-bit RGB that use DSC, and not at lower signals that don't require compression, as you can see here, but we can't be sure it's DSC causing the issue. We noticed a similar thing with the Gigabyte AORUS FV43U, although it's less visible on the M28U and not as consistent as sometimes it would be normal. We noticed a pixel inversion issue with pattern #3, which caused stripes to appear, almost in the same spot as the video. We couldn't replicate the issue with real content, so we tried to see if certain test patterns behaved the same. You can see in this video that there are color glitches with certain content. We received user reports about pixel inversion and color discoloration issues with high-frame-rate signals using Display Stream Compression (DSC). While running Windows ClearType can help improve text clarity a bit (top photo), it's not necessary, as text looks good even without it (bottom photo). The Gigabyte M28U has outstanding text clarity thanks to the high-resolution screen and high pixel density. We confirmed that the HDMI 2.1 ports are limited to 24Gbps. Updated the firmware and remeasured the input lag. We rechecked the black uniformity, reflections, and screen dimensions. We corrected a mistake in the Additional Features section. Looked into issues with Display Stream Compression. Retested the peak brightness and color volume after updating the firmware to F07. 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 working properly. We corrected a typo in the measured brightness after calibration. Updated the monitor to firmware F10, which changed the results in SDR Brightness and HDR Color Gamut as the peak brightness is lower and the tone mapping is worse now. Also confirmed that 1440p works with the PS5. Added that the MSI Optix G321CU has higher HDMI bandwidth in Video and Audio Ports.Īdded that the newly-tested Gigabyte M27U gets brighter in SDR.Īdded a note in Text Clarity to say that square images are slightly stretched horizontally, although it isn't a major concern.
