Hi guys, I recently bought a new TV after our old hand-me-down finally crapped out. The old TV was a Samsung LN52A650 - a pretty beastly LCD from 2008. The TV looked great when it worked, and I don't recall noticing any discoloration or clouding on it. The new TV is a TCL 55S405. Granted it's a much cheaper set than the old Samsung was in 2008, but seeing as it's 2017 I figured the technology had just improved and gotten cheaper. I really like the TCL - viewing angle isn't as good as the old Samsung, but the picture is nice, at least once calibrated a bit. For $370 at Costco I couldn't pass it up. However there is one issue - during letterboxed movies and dark scenes in TV shows, I notice "clouding" or what is sometimes called "torchlighting" in the corners. It's not SUPER noticeable, but when the TV is completely black, I can clearly see 4 lights in the corners shining into the center of the screen, with a sort of dark circle halfway to the center. I've read that light bleed and clouding/torchlighting is a common issue with newer LED TV's. What I'm trying to figure out is - have I bought a lemon and is it worth exchanging, or is this an acceptable amount of clouding? I've uploaded a picture. The overall picture brightness is set to normal (separate setting from black level/brightness) and the backlight is set to 85 here. Thank you to everyone in advance for your advice.
