What to do when screen is cropped or colors look different for S8 Dex Mode
If you only see a part of the screen or different colors on your TV or monitor, go to the Settings menu of the relevant display, and try to resolve the issue to some degree via the Color/Resolution settings or Screen Size settings.
NOTE: Currently, Samsung DeX itself doesn‘t support a feature for changing the resolution. We will try to support this feature in the future.
1. Go to the Settings menu via the connected TV or monitor.
2-1. In the Screen settings, change the screen size or image size.
2-2. In the System settings, change the input method from HDMI mode (PC/AV) to PC.
1). The access to and name of the settings menu may vary depending on the TV or monitor.
2). Samsung DeX officially supports Full HD (16:9, HDMI supported) monitors. If your monitor only supports a resolution below Full HD or is defective, the Samsung DeX screen may appear blurry.
