Apparently Nvidia has adopted stricter EDID rules and after Nvidia driver 512.95 the RTX 3000/4000 cards can no longer produce a working signal on my Sony X95K or any of the newer HDMI 2.1 and VRR capable sets. You only get a frozen garbled image on all the HDMI ports. Some users have reported making it work for a while but it is easily broken once the Graphics card and TV does a new handshake.

The only way to get a working signal form [PC RTX 3000/4000 -> TV HDMI] is to set the HDMI 2.1 port 3 or 4 to Enhanced VRR. Standard, Enhanced and DV does not work. As port 1 & 2 doesn’t have the VRR option so you can’t get a working image out of them at all.

This is a crippling problem as when the HDMI input is set to Enhance VRR it locks you into (VRR) Game mode and you aren’t able to change to other modes such as Cinema for Motion Smoothing when watching video or Clearness in regular Game mode for 120fps + Clearness (BFI) gaming because this requires input to be Enhanced only. Neither can you use Graphics mode for PC work and web browsing that uses a different Local Dimming algorithm that is suited for text and flat colored graphics.

The only working solution to change modes I’ve found is to use a Displayport > HDMI active dongle. Now you can set the TV’s HDMI input ports so Standar, Enhanced, DV and VRR. But VRR doesn’t work through DP to HDMI so you still have to physically change the HDMI cable to the GFX cards HDMI port when you want to use it and then back to the dongle for other tasks.

I’ve made a post on AVSForum about the issue with some pictures, This issue has been discussed a lot in the X90J and a bit in some others as well.https://www.avsforum.com/threads/hdmi-is-broken-on-newer-sony-tvs-with-nvidia-rtx-3000-4000-series-cards.3260397/

@Rtings, can you guys please make an issue out of this, maybe even an article? And please test and bring this up in all reviews for the newer Sony 2022 TVs and future ones as this severely debilitates the TVs usage as a PC Monitor.
