Just got an HP EliteDesk 800 G4 DM 65W for Christmas, took it home to plug into my 4K TV, booted Stadia to check it out and it runs terribly. Choppy, stuttering almost constantly, running at a max of 1080p but dipping below fairly often, significant lag on everything, absolutely unplayable. I've used a Chromecast Ultra to play Stadia on this TV (and WiFi network) and it works perfectly, and I tried this PC out on another TV (albeit an HD TV and not a 4K TV) in another house with a slow connection speed before taking it home, and Stadia worked fine. The WiFi in our house is a gigabit per second, and I'm getting a solid four to five hundred Mbps from every speed test I've checked on the device, including the Stadia speed test. The PC has absolutely no issues running a 4K YouTube or anything else, and it's even powerful enough to run, say, The Stanley Parable or something similar at 4K (not at a high frame rate, but still)
The screen's a Vizio M-Series 58" 4K HDR Smart TV, if that means anything to anyone. Can't for the life of me figure out why it's running like this. Is there a hardware limitation that I'm not seeing here? I'll fiddle with whatever settings I need to.
