We have a north facing lounge with an extension, so doesn't get much sunlight and tend to just have a lamp on at night. Looking at screens in the showroom some look really good as brigher and colour great, but apparently are better for brighter rooms. 4K UHD apparently is good for darker rooms, looked a bit dull.
If you've got a dark room, what tv screen have you got? Also, do you think the blacks stand out enough and are you happy with what you've got.
Ideally we'd be looking at QLED, or LG do nanocell and QNED. We haven't got the budget for OLED.
