We used them all the time for work.

If you get the crap ones, they will look crap.

However any of the midrange ones will be brighter than the equivalent consumer (they have to operate in full sun 24/7)

You will not find an oled though, because they have yet to be full duty cycle (well I've not looked, but if they do exist, they will be many monies.)

Get yourself a nice NEC 4k, you'll be happy. unless you want 8k (good luck finding a source for the 8k) or you really like the motion smoothing of poorly setup consumer TVs.
