I'm Happy With The 3D Performance On My XBR75 X940D
Other than for the fantastic picture and 4K capability, the main reason I bought the XBR X940D was for the 3D capability. Since TV manufactures seem to have decided to abandon those of us who enjoy 3D at home as a failed revenue stream, due to their own inept marketing, but that's another story, I wanted to replace my existing set with one that was 4K and 3D. Having had the set for a couple weeks and watching a lot of 3D Blu-rays to test out performance I have to say overall I'm very pleased with the 3D performance of this set even though there are the usual problems with crosstalk found on most LED sets with active glasses.
The picture on this set is undeniably gorgeous with deep blacks and superior up scaling and motion processing. This is the finest TV I have ever owned and I'm more than pleased with it. It handles the 3D image very well but crosstalk will raise it's ugly head in the usual problematic areas of very high contrast. For instance a black bow tie against a bright white shirt. With the amazing black levels of this set I guess it's to be expected as I have only seen 0 crosstalk on DLP units and none of these had the great black levels of this set. Having just seen Captain America: Civil War at the theater in 3D I was constantly reminded of the poor black levels on the theater screen and how great this is going to look on my X940D.
The 3D settings on the set give you a choice of 3D depth and glasses brightness. The 3D depth adjustment seemed to work best at the default 0 setting. This gave the least amount of crosstalk and the overall the depth and pop-out of the image seems to me to be what you would see at the theater. On the +1 setting crosstalk started to appear in the usual problem areas quite noticeably. The X940D uses Sony 3D glasses that connect via Bluetooth and I've had some problems getting these to connect to the set. Once connected they worked fine, although I've had to reconnect them on almost each session. Also, I had a problem when the Bluetooth transmitter in the set turned itself off and couldn't be turned on again. I had to re-boot the set back to it's original factory settings to be able to turn the Bluetooth back on. Overall I like the design of the Sony glasses as they are quite light and have a removable nosepiece that make wearing them over glasses more comfortable. As mentioned above the set also has a glasses brightness control that makes incremental changes in the amount of brightness that comes through the glasses. I've found the medium setting seems to present the best picture brightness to my eyes.
I tested the TV on a number of Blu-ray 3D discs that were somewhat problematic for crosstalk on my past 3D sets. (a Samsung and a Sharp Aquos) All looked amazingly better on this set as the added brightness and contrast made the pictures pop in a way, even with 3D glasses on, that they didn't on my other sets. Problem discs on my past sets such as How to Train Your Dragon, Disney's A Christmas Carol, Monsters vs Aliens and Polar Express, among others, all looked much improved. Films with little crosstalk problems such as Jurassic World, The Avengers films and Hobbit series all looked fantastic with added boosts to color and contrast to make them look great.
So, bottom line I recommend the X940D as a good choice to enjoy your 3D Blu-ray collection and take advantage of all the benefits of 4K and Sony's excellent color and motion processing. The large scree size also adds to the immersion while watching a film. It's not perfect but close enough for me to feel secure I will be able to enjoy my 3D library of Blu-ray's until the TV industry decides, if ever, to give home 3D another shot.
