First off, this TV is a great value given the ~50% price drop from the launch MSRP. The shift in the television marketplace from 2016 to 2017 onward seems to be towards less features for more money. For example, this is one of the last native 3D ready TVs on the marketplace. If you're interested in 3D, even in passing, this TV is your last chance. From 2017 onward ALL television manufacturers decided to drop the 3D feature as well as native 120hz refresh rates at this price point. Don't be fooled, most TVs under $2,000 in the 2017 line of televisions have 60hz native refresh rates with image processing that they use to claim 120hz or higher effective refresh rates (some will claim as high as 900hz). You can still get higher native refresh rate TVs, but they start getting pricey for no apparent reason other than manufacturers trying maximize profit by locking away better image quality at higher price points than prior years.The XBR55X930D arrived impressively packaged and was fairly easy to remove from the packaging. You'll need two people to carry it as it is very thin and heavy. Be especially mindful of the top of the TV as it is as thin as a Starburst candy. The stand looks sophisticated, but I felt a clean wall mount makes the most of the aesthetics that Sony put into the design of the device. Mounted against the wall the TV looks posh but not out of place. It's not just a TV it's home decor, on or off.Powering on the TV for first use has you sprint through a gauntlet of questions and Google account login credentials. Folks who have purchased brand new Android phones are keenly familiar with this process. Prepare to devote 30 minutes navigating all the set up menus and waiting for your TV to update its Android TV OS software to the latest version. Get familiar with the accompanying TV remote because you'll need to master it in short order. Once updated, you'll be presented with the Android TV menu.Android TV is the operating system that manages all aspects of the XBR55X930D's functionality. It has a lot of useful features if you take the time to get the most out of it. For starters, get familiar with the accompanying TV remote. Learn to use the, microphone, input, navigation arrows, enter, back, and home buttons on the remote control. You'll be using them A LOT and you'll want to be able to locate them by touch. When I mentioned in the title that you will need patience to get the most out of the TV... playing around with Android TV will take some getting used to. I highly recommend you first go into the Picture Settings menu and turn off MotionFlow as it creates the dreaded "Soap Opera" effect. Which in my opinion hurts the image quality despite Sony marketing it as an improvement. Initially I had difficulty activating the 3D functionality over various content sources and syncing the 3D glasses (sold separately). I also had trouble finding the right media player to play content streamed off my home network (I found that Kodi is a decent media player but needs configuring). Again, you'll need to learn how to navigate all the functionality of the device and various quirks. One of the quirks that I've noticed on both the Android phones and now Android TV is that the devices function best if you restart them (as opposed to sleep mode) every few days to clean up memory leaks that might slow down the OS. Nothing huge, but just an FYI.Once you've gotten the TV set up the way you want and the content available for viewing then the fun really begins. The image quality is simply gorgeous. 4K (2160p) videos in particular look amazing. 1080p and 720p videos look great also despite the fact that the TV is made for 4K native output. Even 480i videos look no worse than they did on native SDTVs despite being blown up to a significantly larger size than their native resolutions. I initially experienced "jitter" with 4K video over my laptop that was advertised as supporting 4K, but resolved this by connecting a more powerful computer to the TV. 4K on the Youtube app plays flawlessly if you want a free app based source for 4k video content. The TV's sound output is what you would expect from a TV as thin as a piece of candy, nothing spectacular... but Sony showed effort. I purchased a $130 sound bar / subwoofer combo and connected it through the HDMI 4 ARC (audio return channel) port. This special HDMI port allows you to control connected devices (the volume of the sound bar for example) through the TV remote, effectively turning the TV remote into a universal remote control. I would recommend a sound bar to get the most out of your audio experience with this TV. I wouldn't spend more than $200 at the most for a sound bar as sound quality DOES NOT scale with price in that market.As of writing this review, I've owned my XBR55X930D for about 2 weeks. I think 5/5 stars is a fair score for this device. It's a thoroughly impressive TV...full stop...from industrial design and physical aesthetics to image quality and feature set, Sony went all out. It took more of a time investment to learn how to get the most out of TV than I was initially expecting. However, I've gotten over the learning curve and I am enjoying 4K video, 3D gaming and movies, seamlessly casting content from my phone directly to the TV, and music via Spotify with no problems. For those looking for more than just any TV to watch prime time TV shows on before bed, this TV delivers. It's the perfect TV to couple with a gaming rig, a NAS holding your media collection, or simply use the suite of Android TV apps for all your content sourcing. It took me a few months to finally pull the trigger on a new TV, but this has been one of the best electronics purchases I have ever made.
