Right now, Sony has some good price drops on a couple of their well-appointed, 4K televisions.
For the 2017 model year, they have a couple of TV 'families' that are really nice. The 800E and 900E models offer a lot of excellent features and excellent picture quality while not literally requiring a second mortgage on your home to buy. They have also instituted some price drops that make these particular sets really good values for what you get.
The 800E family offers 4K, HDR, Edge lit LED with Frame Dimming and Sony's Tri-Luminous Display processing. The picture quality on these sets is really nice - I have one.
The 900E family offers everything that the 800E family has except that it's a direct lit FALD set (Full Array, Local Dimming) which gives the best backlighting and overall PQ. It also has the X1 processor (which means it -may- qualify to get the Dolby Vision update). Picture quality on these sets is excellent - I have one.
Current pricing on the 55" model in both families makes them excellent overall values with the 800E being $800 and the 900E being $1000.
While these prices will be a bit shocking to some, and understandably so, they are some of the best prices I've seen on sets with really high quality 4K / HDR panels. And if you want a much larger screen, the 65" or 75" 900E would give my 940D a run for the money, and their prices are considerably less than I paid for the 940D.
Anyway... If you're in the market for a really nice TV that's a bit on the larger side, check out these 55" models before Sony pulls the sale prices.
