From a google search that said "18GB splitter that works with PS4 pro" that took me to the Sony forums, all links from posts from that search.

​

Edit : There is no one solution. People are suggesting all kinds of different units. Probably difficult to get a general consensus on just "one" splitter that works perfectly above all others.

I have 3 HDMI 2.0 ports on my tv, with my Xbox One X on port 1, HDMI switch on port 2, and PS4 Pro on port 3.

I use this one and it works really well paired with my HTPC. My HTPC is on 24/7, but whenever I take my Switch out of sleep mode, it automatically switches to the Switch, and when I put it back to sleep, it automatically switches back to my HTPC, so I don't have to use any extra remotes or anything else. I'm really happy with it.

I would give this a go and have all the systems running through it before the AVR.

Worst case, if it doesn't work out, you could return it but the advantage of going this way over ARC is that you will retain lossless audio, which you would use going the ARC route.

These noname switches should work:

According to user reviews they all support 2160p60 4:4:4 (and HDR).

If you want a brand name you can get

Ligawo 3090063 HDMI Switch 3x1

Sewell SwitchDeck, 4K HDMI 2.0 Switch 3x1

They also have a 5x1 version if you have more than 3 sources.

I own the Ligawo 5x1 myself.

This one doesn’t seem to be bad.

Was in your same predicament with the same tv. Except I don’t use my gaming rig (have a monitor for that) and needed an Apple TV 4K input.

Here’s one with 3 ports that I know works well and supports HDR

ROOFULL 3x1 HDMI 2.0 Switch Switcher 4K HDR HDCP 2.2 with IR Remote, Support UHD 4K 60Hz (60 fps) 4:4:4 18Gbps / 3D / 1080P / Dolby / DTS 7.1/5.1 for HDTV, PS3/4 Pro, Xbox, Roku, Apple TV [3 In 1 Out] https://www.amazon.com/dp/B074Z6Z2NY?ref=yo_pop_ma_swf

I use it

Do a factory reset of the monitor via it's settings.

Verify that your cable is a "premium high speed" HDMI cable not "high speed", text should be written on it though crappy cables makers will fake it.

Set the monitor it it's own picture setting to black level = low

Set the PS4 to 2160p YUV output.

Now try turning on HDMI Ultra Deep Color.

If it still doesn't work that is a strange one, it's possible the monitor is faulty or the peculiar nature of Sony's PS4 HDMI handshaking which is known to glitch out on various displays is the culprit.

You could try a cheap 4K HDR switch to act as a handshaking buffer between the monitor and the PS4. The monitor will not see the PS4 only the switch, which will in turn pass the signal from PS4 to display.

I would recommend getting 2 certified premium high speed HDMI cables as well to rule out any cable issues.

It was actually given to me, but it appears to be this one: ROOFULL 4K HDMI 2.0 Switch 3 in 1 Out HDMI Switch 4K 60Hz HDR Dolby Vision HDCP 2.2 3D 1080P Switcher with IR Remote, Compatible for PS4 Pro, UHD TV, Xbox One/360, Apple TV (3 Ports) https://www.amazon.com/dp/B074Z6Z2NY/ref=cm_sw_r_cp_apa_i_j-MDCbH8H0010

4k, HDR, 60 FPS, 3 inputs.

It took me awhile to find one suitable, but I've been happy with this one
