I have a MAG254W1. In the inner portal, I have set the video output to be 1080p-60 and resolution to be 1920x1080. I clicked on OK to save/reboot. But after reboot, the resolution goes back to 1280x720. I have changed it in the BIOS at boot up to 1920x1080, saved and reboot, and still it reverts to 1280x720.
To try other things, I have changed the HDMI cable and even tried another HDMI port on my TV (Samsung 4K). There's no change.
Anyone know what can be the issue and/or what else I can try?
