For the last 6 months I've been trying to fix similar issue between my HTPC and my new LG 4K TV (65SK7900PVB). Every time i enable the HDR on my TV and Windows its working fine until i run or exit games...then TV start to lose signal randomly.
At the beginning i thought its a GPU card issue i upgraded my (RX580 8GB supports HDMI 2.0b) to GTX 1080) and that didn't fix the problem!
Then i followed most of the online threads advice's about changing the HDMI cable and replaced what i had with the famous Belkin Ultra High Speed HDMI Cable! and that didn't work either.
Now after you mission EDID it starts to make sense to me this could be the real problem.
Awesome, glad to have helped! LOL I created an AVS account specifically for this problem as well. If you do end up purchasing an EDID managing device (whether its from HD Fury or not), I have a few notes of advice.
- If you launch a brand new game for your first time, sometimes Windows will decide to display the game at a different resolution than your desktop (i.e. desktop was displaying at 4k, but game tries to display in 1080). If this happens, the HD fury device will either take much longer to recatch the signal or it will completely lose it. But once you change the in game settings to match your native resolution, this problem will never happen again (for this game). Most games however should automatically detect your native resolution though.
- If you are having trouble with the signal being lost alot on a particular game, you should try changing the in game settings display mode to borderless (default is usually full screen). Borderless allows the desktop to still technically run in the background, making it so your devices don't have to participate in an extra EDID handshake. In fact, you might want to try this on your current system before purchasing any EDID managers.
- More often than not, any problem you experience with loss of signal with an HTPC is going to be because of HDR. The HD fury device I bought will succeed in almost 100% of all changes that are made to the display that include changes to resolution and refresh rate. However, if you make a change in HDR settings, the chances of the HD Fury device successfuly completing the EDID handshake without your intervention (switching the inputs to regain the singal in my case) are now only 50%. Long story short, pay careful attention to what kind of HDR you are running.
- This device takes a little longer to capture the very first signal it detects. Meaning that unless you have a hard drive (slow boot time) your bios will finish loading before your TV displays the picture. I have an SSD, so the first thing I see when my TV displays the signal is my Windows login screen. This isn't that big of an issue for me however since I rarely need to actually go in the BIOS. And if you really needed to, you could always bypass the EDID manager (unplug it) and memorize the key you need to push to enter the BIOS settings. Then, even with the EDID manager plugged in, you could still access your BIOS by repeatedly pushing the key you memorized to access the BIOS. You don't need to see a picture to enter the BIOS, it's just nice if you can because you can see and be reminded of what each key does (i.e. F1 for safe mode, F9 to enter BIOS settings, etc.).
Final Note - I will still experience my display issue about 15% of the time, but it is usually resolved by resetting the HD Fury device (it has its own processor so treat it like any computer that will occasionally have a hiccup). And even in the rare scenarios I do have to cycle the input to regain my signal, its not very irritating because it happens so rarely. Without this device, I would lose the signal every single time. Main point is that this display issue can't exactly be permanently cured with this device (with the work I've done with it), but it can be make it work nearly perfectly and make its problems much easier to manage when they do arise.
