Turn off gaming mode permanently - Roku Community
I use an Onn QLED TV as the laptop's secondary monitor on native 4096 x 2160 resolution, note that is slightly higher than normal 4K which is 3840 x 2160. I have gaming mode turned off in Windows settings. I have the TV's HDMI mode set to "Auto", because turning it to compatibility disables HDR, and the therefore much better color range.

Onn roku tv turns on and off I have bought a onn roku tv from a local Walmart and after at least 2 weeks after buying, the red light goes dim turns on then turn right back off immediately then it does it again after about 2-5 seconds.
