A:Answer Your receiver may be able to switch signals via HDMI up to high-definition resolution (1080p), and perhaps 3D, but unless you bought it very recently, it's not going to be able to switch 4K signals that it can pass through to the LG C7 OLED 4K HDR Smart TV - 65" Class (64.5" Diag), Model # OLED65C7P. The entire chain needs to be 4K compatible. So if you want to feed it 4K via HDMI sources, and want to switch those sources using an AV receiver (as opposed to the TV), you'll need to buy a new receiver that handles those 4K sources...^IFV
