With your budget, take the 75U78N at Costco, 2yr warranty + you can extend to 6yr for 150$ I think.

Hisense especially the 78N (and 88N) have absolutely beautiful stunning picture, maybe one of the best for the buck, check the review www.rtings.com/tv/reviews/hisense/u7n-u7-u75n it handles DolbyVision, HDR, 144Hz, etc

It does not use a shitty OS like roku nor ads like Samsung. You may need to have it plugged on internet for 1st boot and FW update, but after this you can obviously disconnect it, plug your HDMI device and that’s it, it will act as a dumb monitor.
