Sure! It's the Beelink with the 5500u. I am using steam link and everything is wired. No resolution problems, but I do have about one stuttering issue a week for a second or two. At 4k I had alignment problems that didn't make sense (everything was shifted 3 inches to the left) but my eyes aren't great so 1080p fine for me. Moonlight would probably fix it but I'm lazy.
HoloISO has been great. I had a Bluetooth issue where it wouldn't come back from sleep, but there was a setting I added in desktop mode that took about 3 minutes that fixed it right up. I use Xbox clone controllers or my old stadia controllers that I've set up for Bluetooth depending on what's closest (did I mention I'm lazy?).
Ask questions and I'll answer. I like talking about my setup.
