EDID Issue with my 4311
I'm having what I believe to be an EDID issue. My Denon AVR-4311 is giving me a black screen from my HTPC (Gigabyte Windforce NVIDIA Geforce GTX 1050TI 4GB OC Video Card/Windows 10). I've changed the resolution and refresh rate using both the Windows and the NVidia software to those that the Denon definitely supports. I've also changed settings such as UHD color on the Samsung TV. However, on my 4311 in the living room, I can only get a signal occasionally, but after a restart I get a black screen and then the Denon logo again. I have none of these issues when connecting the same HTPC to my Denon AVR-3311 in my bedroom. The 4311 has never had a problem with any other HDMI source though. I have a cable box, blu-ray player, Chromecast, etc... connected to it, and it works like a champ. The video card in the HTPC has three HDMI outputs and one Displayport output. I bought a cheap Displayport to HDMI adapter. Surprisingly, it helped a lot. I still have to occasionally restart the HTPC due to a black screen or wonky resolution issues, but I can live with it for now. I'm still getting DTS-HD and Tru-HD even with the adapter. I'm thinking of buying a device called an HDMI Detective Plus that supposedly helps with issues like I'm experiencing by storing the EDID info of the receiver and making it constantly available to the HTPC. A lot of people say it worked for them. A couple of the positive reviews on Amazon specifically mention Denon receivers. If I can get one used for $50 or less on ebay, I'm going to pick one up. I'll report back. If you have any other suggestions, I'd appreciate the help.
I'm extending the display of my HTPC. I'm running one HDMI cable directly to my 4K TV and a second HDMI cable (and Displayport Adapter at present) to my Denon. The Denon won't pass through 4K, and the Samsung TV won't pass through 7.1 audio. Both ARC and Optical are limited to 5.1. Extending the HTPC's display works perfectly, giving me the best of both worlds, a 4K HDR picture and 7.1 channel audio, using my 3311, but I've had problems with my 4311. I'm hoping the HDMI Detective works. I will eventually upgrade my receiver, but I'm still very satisfied with it other than this one issue. I have a 9.4 speaker system connected to the 4311 that sounds really good.
I've reset the 4311 (twice), I've reset the PC, I've restored the TV to factory settings, I've tried different HDMI inputs on the receiver and different HDMI outputs on the HTPC, I've tried various NVIDIA drivers, etc... but only the cheap Displayport adapter has made much difference so far.
