After the latest firmware update, all 4 hdmi ports are supposed to be hdmi 2.1 capable of 4k/120/hdr but I’ve noticed weird behavior with ports 3 and 4. I originally had my PS5 connected to port 3 but it wouldn’t sometimes give me any sound. After talking with Vizio support I was told to plug the PS5 into port 1 or 2. But since port 1 is EARC, I decided to use port 2. So far, no problems since. Now with my Xbox Series X, I have it connected to port 3. It works for 4k/120/hdr/VRR in theory, but it sometimes does this weird backlight flicker that gets annoying. Other times it will come through as a scrambled signal and I’ll have to turn the Xbox off, then on again for it to correct itself. This happened even when I tried ports 1 and 2 to test. Also, it appears when all gaming features are enabled on Xbox - 4k/120hz/hdr/VRR and you play a game like Black Ops Cold War at 120fps, the tv will skip frames at times. Really weird. I’m hoping Vizio releases another firmware update soon to correct this. But overall for the price, this is a really good gaming tv and movie watching tv with deep blacks and great hdr performance.
Sorry, there was a problem. Please try again later.Read my previous review. This tv has several issues with series x. No VRR, stuttering, dim and 120hz. I returned it HDMI 2.0 Full Bandwidth Yes (HDMI 1,2,3,4) HDMI 2.1 Class Bandwidth Yes (HDMI 3,4) EArc is hdmi 2
Sorry, there was a problem. Please try again later.As far as I can tell from the manual, all the hdmi ports support earc and hdmi 2.1 is supported on ports 3 and 4(on the side)
Sorry, there was a problem. Please try again later.HDMI 2.0 Full Bandwidth Yes (HDMI 1,2,3,4) HDMI 2.1 Class Bandwidth Yes (HDMI 3,4) If you are plugging a Series X. I recommend it on hdmi 3, this tv still does not suppoer VRR and will give you issues. I returned it because of that. Give it a try but eventually dimming becomes annoying....
