Exceptional
It's impossible to go back to a normal screen once you've had a taste of 4K oled.
Response time is non-existent, which is quite exceptional for a television, so it can be used as a PC monitor.
What's more, the screen goes up to 120 Hz, in G-sync. It's royal.
The price is still quite high, but much lower than for competing PC oled screens with a smaller diagonal.
However, you'll need to stand back a little to avoid eyestrain.
Screen used for 800 hours so far, in HDR, on a PC, mixed use (office, web, films, games): no burn-in of the panel so far.
