Bests & Worsts Reviews from Amazon

Purchased this at another retailer, but noticed some negative reviews here. I have a somewhat niche use-case, but it may apply to others. As a software developer, I was looking for a 4K monitor larger than 40". I was initially looking at an LG 43" but that still left text a little small on screen. As an alternative started looking at 4K UHD TV's to use instead. Started with reviews on RTINGS.com and this TV had the highest rating for TV's under 55" for use as a PC Monitor. Initially purchased a TCL P607 55" TV, but it was too large for me to use as a monitor, the pixels had strange dim spots between them, and being so large with a narrow viewing-angle, the edges of the screen were noticeably darker. Swapped that TV out for this one with a slightly smaller screen at 49", I don't need to move my head to see everything on the screen from about 3' away and the viewing angle is much larger with no dimming around the edges. The strange dim spots between pixels in the 55" TCL are not present in this TV. Up close use as a PC Monitor is excellent, as a TV I knew it wouldn't be the brightest or have great blacks, but as a 4K TV under 55" to use as a PC Monitor, this model is unmatched.
