I've been using my Windows 10 media centre PC with my Onkyo TX-NR515 receiver and Samsung UE55ES7000 (1080p) TV for 10 years without problems.
This week I upgraded my TV to an LG OLED65C24LA (4K), and connected it up in exactly the same way. However the new TV will not display the video signal from the PC. Using VNC to access the PC I can see that the display resolution has been (correctly) set to 4K (3840 x 2160). I've tried other resolutions - including the 1080p setting that I was using with the old TV, but the new TV will not display it, no matter which resolution I choose.
If I bypass the Onkyo receiver, and connect the PC directly to the TV's HDMI port, it displays correctly straight away (at 3840 x 2160).
Any idea why the TV can't display the PC's video signal if it's routed via the Onkyo receiver?
