Not me but my son just bought an 85" Samsung 8K TV to use as a gaming monitor. He spent $3800 on the TV, $500 for a bigger desk and $32 for an analog to digital adapter to be able to connect the TV to his stereo. Damn thing weighs about 120 pounds so was a bear just to lift it to put it up on the desk!
Thats cool! - but at the same time, good luck with the 20fps. Assuming he is plugging a PC into it?
