Strange HDMI Issue on Onn TV

Got a new Onn 70" and just started to set up my ps5 when I ran into a strange problem. At first, I would get a black screen but got sound. Tried some of the various power cycling and cache reboot suggestions I've seen before. Eventually, I figured out that if I go into settings and selected compatibility mode instead of standard or auto for that connection then I could see an image. However, at this point, I do not have HDR support at all (my ps5 even says TV doesn't support it but I know it does). I can get 1080p on standard/auto and standard 4k but not full 4k HDR support. I can get 4k HDR on apps. I switched ports and still have the same issue. I have a ps4 that I tested and it got the same problem when standard/auto was on but not when compatibility was on. Even tried an Xbox 360 but it worked with no issues at all. I have contacted Onn Support and am waiting for a reply but thought I would try my luck here as well. 

Thanks for any help.
