Hi All,
I'm having some fun and games with my Q90R having connected it up to my Windows 10 desktop PC (via NVIDIA 1080GTX HDMI 2.0 port). I'm currently trying to get HDR working from the PC on this screen at any resolution 1080p 30Hz/60Hz, 4K 60Hz, but there seems to be what I can only describe as some sort of handshake type issue between the TV and the PC because as soon as I enable "Input Signal Plus" on the HDMI port at the TV, the TV loses signal and my primary monitor flickers continously as it detects the TV and then drops connection. This problem also persists whilst using only the Samsung Q90R too. As soon as "Input Signal Plus" is turned off, it all works just fine, only I cannot enable HDR at all. It works flawlessly at 4k 60Hz, 1080P 120Hz but this is baffling m.
I've tried a variety of short HDMI 2.0 cables which I know work from my PS4 Pro and XBOX One X (1.5m - 2m length), and have tried using all of the HDMI ports from the One Connect box, but the problem persists. I do have a HW-Q70R soundbar also connected to the One Connect box with ARC enabled, and will look at eliminating that shortly.
If anyone else has had a similar problem and found a way to get HDR working via Input Signal Plus without the Windows PC having a total head-fit and found a solution they could share, I'd be most appreciative. I've had a search on the forum and spent a couple hours on google but didn't turn up a whole lot.
Kind regards.
