Last night I, for the first time, carried my tower, key, mouse and yoke across the house to use my 55" OLED TV as monitor (my monitor is a simple 27" Dell 1080p monitor). Let's say that I really, really liked the experience (both for the 4K, even with a scale rendering of 70, and the real estate). 

As everyone knows, large computer monitors are way more expensive than similar-sized TV. I understand why a FPS gamer would be ready to invest a lot of money in order to get super super refresh rates and response times, but for flight simming... Yet before I more seriously shop around for a 50" 4K budget TV (e.g. TCL and Hisense), I want to know whether I'm missing something fundamental here.

Thanks!

@Turpentine, you have to be careful in your choice of TV. For sharp Windows text (use Explorer) the TV has to be capable of supporting chroma 4:4:4. It's doubtful a budget OLED TV would do that and as a result, standard Windows tasks would be hard on the eyes.

The other consideration is burn-in on an OLED. They are more suceptible to it than standard LCD displays. Sure, the size make it an impressive experience but you need to take those factors into consideration.

Thanks! I knew about burn-in, which is why I was thinking of going with a budget LED instead of OLED (at the cost of sacrificing great contrast). I didn't know about chroma 4:4:4 and Windows text, though to be honest I had forgotten to turn on that feature on my TV last night and it still looked great.

I probably should just eventually buy a budget TV, bring it home, see how it looks and return if I don't like!
