This TV supports most common resolutions. It can display proper chroma 4:4:4 in all resolutions except 1440p @120Hz. To display chroma 4:4:4, the input must be labeled PC, and for high bandwidth signals like 4k @60Hz + HDR, the Input Signal Plus setting must be enabled for the port in use. Game Motion Plus can’t be used when VRR is enabled.
While this TV is supposed to support 4k up to 120Hz, we weren’t able to display a signal higher than 4k @60Hz, even with the same computer and settings that we used to test the Q90R, which worked perfectly. We expect that it requires an HDMI 2.1 source, and since none are available at this time, we’ll retest it when we can and provide an update.
