The finalists by price:
$389.99 Black Friday from Nov. 18-28th at Costco and Costco.com with free shipping: http://www.costco.com/LG-49%22-Class...100301368.html
strengths: Direct backlight; Picture quality remains when viewed at an angle; Smart platform is featured and intuitive; Upscaling of low quality content is good
weaknesses: Uses less accurate RGBW pixel structure; Uniformity is below average; Blacks appear gray in dark rooms; This is one of the worst TVs we have tested for the black uniformity yet in 2016
For the price I cannot beat this deal. It looks like a winner, and I do not have to stand in line for days. I am a little concerned about its black level though.
So it has great contrast but in a dark room where that helps, the fixed backlight is too bright? Seems that negates the usefulness of that good contrast ratio.
This is the one that seems like the best overall given his tendency to prefer torch mode anyway, and the price is good, but I am a little concerned about Panasonic's reliability and service given their TV business seems to be winding down.
The peak white level in the contrast measurement by Reviewed.com is 209.8 and the reviewer complained that he could not calibrate the luminosity
because the backlight is not adjustable. The RTNGS review shows the peak white level nearer 100 in the RTNGS contrast measurements. I wonder if the 'deep contrast' reported for this Panasonic is real, or just an artifact of its hard-wired torch mode backlight.

Dave, are you sure about this comparison? The review of the LG UH5500 said the picture was dim. Is that just a relative quality of VA compared to IPS, or does UH5500 have some sort of design flaw? A dim TV with high input lag that we cannot return is a non-starter.
Peak 2% Window: 294 cd/m2
Sustained 100% Window: 294 cd/m2
compared to the other LG with IPS:
Peak 2% Window: 404 cd/m2
Sustained 100% Window: 398 cd/m2
That is a 25% difference in measurement. Seems yuuuuge. One of the prime attractions of the 4K televisions is the pop of the brightness IMO.
I found one last contender -
Dave, Does this Samsung really do HDR?
Peak 2% Window: 425 cd/m2
Sustained 100% Window: 430 cd/m2
That is only ~7% higher brightness measurement than the LG IPS panel at the top of my list. They still get 24fps wrong? Any TV with notably bad glare seems like something we want to avoid.
The whole point of going with 4K was my assumption that the newer panel technology is inherently superior, based on the brighter and sharper appearance of the UHD televisions in the stores. Also, I was wanting to avoid TV from an obsolete HD product line that might not be maintained by the manufacturer. Did I get this assumption wrong?
Candidate 1: faked UHD, bad blacks.
Candidate 2: no backlight adjustment, too bright for theater viewing, maybe faked contrast.
Candidate 3: poor brightness.
Candidate 4: maybe fake HDR, high glare, judder at 24fps regardless of selected playback mode.
If the only advantage of 4K in a 50" is the higher resolution at close distance for computer monitor/gaming, then the LG IPS (cadidate 1) is the only panel that makes sense to buy because it is the only one with viewing angle wide enough to sit close, and its 'fake 4K' compromises the resolution even at close distance anyway plus its contrast is poor. But at least it will have a bright picture in a daylit room and the picture will still look OK from just about any vantage point in the room.
Lacking a comparable review spec on the Panasonic, it is difficult to compare its brightness to the other three, but without a backlight adjustment that information seems moot anyway.
Tough choice. Should I start over my shopping with HD? Given the compromised performance of all these models I am tempted to just pay as little as possible or junk the whole UHD concept in this price range.
