More practically, when I am not using that, I just watch tv shows and such on my desktop computer running NixOS with a nice and modern (1440p 170Hz high quality but not highest possible end IPS) monitor over displayport.
Other options include a projector, buying a very large computer monitor marketed panel, or using something that is modern enough to be fine, but not so new that it has malware in it (like a friend who was moving gave me a very heavy but also very nice plasma tv, with zero malware on it).
Basically, anything except something marketed as a consumer grade TV. The last time that I had to displeasure of dealing with that it was when my parents bought one and asked me to set it up, and the built-in Roku software refusde to even display from an HDMI or DP input unless it was logged in and connected to WiFi! Alas, I was not able to convince them to return it, but I did decline to have anything to do with it.
