Any major issues?
Make sure to put your TV in “gaming mode” or whatever it’s called in yours. Otherwise it’ll do some extra calculations to improve image quality which will cause noticable input lag. I’ve struggled with that issue for a while, thinking the Deck itself caused the input lag when displaying on an external display, but it actually was the TV which caused it. After setting that mode, together with FSR, it was basically the same performance as in handheld mode from what I can tell so far.

As long as you render the games at the Steam Deck native resolution (i.e. 1280x800) and use the FSR upscaling option this works perfectly. I do this to output to my 4K TV and the games run more or less the same as they would on the Deck itself with great visual quality.
