The highly anticipated face-off between the flagship TVs from LG, Panasonic, Samsung, and Sony is now complete, and the winner is...

After five voting sessions and 77 valid ballots over the course of two days at the CE Week trade show, the results of the 2015 Value Electronics Flat-Panel Shootout are in. The four UHD/4K contestants were the LG 65EG9600 curved OLED ($8999 MSRP), Panasonic TC-65CX850C flat LED-LCD ($3499 UPP), Samsung UN78JS9600 curved LED-LCD ($9999 UPP), and Sony XBR-75X940C flat LED-LCD ($7999 UPP). (UPP stands for Unilateral Price Program, which is the lowest advertised and selling price authorized by the manufacturers; MSRP is the older Manufacturer's Suggested Retail Price.) All three LCD TVs employ full-array LED backlighting with local dimming and VA (vertical alignment) LCD panels for better on-axis blacks, though this compromises their off-axis performance
 compared with IPS (in-plane switching) LCD panels.

And the winner is...

The LG 65EG9600 OLED!

But as you can see in the results from non-experts below, it was a very close race between the LG, Samsung, and  Sony .

There were 72 valid ballots from non-experts; six ballots were discarded because they were not properly filled out. As you can see, the LG OLED won in five of the seven voting categories: black quality, perceived contrast, color accuracy, off-axis performance, and motion clarity. The Samsung took the top spot in screen uniformity and day mode (viewing with the lights on).
As you might expect, the LG OLED easily won the black quality, perceived contrast, and off-axis performance categories, but the others (except screen uniformity) were quite close. And the combined totals were very close as well, with the Samsung edging out the  Sony  for second place.

The overall ranking was the same for the five ballots submitted by experts (professional calibrators and TV reviewers), but not in all the individual category results:

Among the experts in the audience, the LG OLED won the black performance, perceived contrast, and off-axis categories, while the Samsung took the top spot for color accuracy and screen uniformity, and the  Sony  won for motion clarity. In the overall rankings, it was another tight race between the LG, Samsung, and  Sony , with the Samsung taking second place.
I've reserved the first few comments in this thread to add the calibration results for each TV, a description of the balloting and tabulation process, some of the comments written on the ballots, and more detailed comments about the TVs' performance from my perspective. But for now, I wanted to post the voting results ASAP.

Congratulations to the LG 65EG9600, and thanks to all four companies for their excellent entries in the 2015 Value Electronics Flat-Panel Shootout! Also, many thanks to Robert Zohn, president of Value Electronics, his wife Wendy, his daughters Lianne and Katie, and his support team, Lisandro and Rogelio Maldonado, for organizing, schlepping and setting up all the equipment, and presenting the entire event at CE Week; I was amazed at how much work went into it, and I'm honored to have been part of it this year.
