When connecting Live Gamer Ultra (GC553) to my 4K TV with PS4 PRO input source I can’t select 2160p (4K) resolution at PS4 PRO settings, only 1080p available, what to do?
Please ensure that you connect the 4K60 Pro to GC553 and an HDMI 2.0 on the 4K TV.
Note that some TVs will need to adjust further settings:
Press the Menu button your TV remote.
Scroll down and choose options.
Select HDMI Input Mode.
Set the input mode to HDMI 2.0
