My Windows desktop has a LG 4K monitor and Radeon x570 graphics card. The latest drivers are installed for both devices. I have the latest build of TV 13 installed.
If I turn on my computer with the monitor off, the TV remote resolution is stuck at 640x480. There are no other resolutions offered. All I have to do is turn on my monitor and the remote resolution instantly changes to 3840x2160 (what I want).. The behavior occurs with my Windows laptop, iPad and iPhone.
Any idea why this is happening and how to fix it?
