      Great Price for quality and brand

      I totally love my upgrade on tv. I went for almost 10 years with a SONY BRAVIA 42inch regular definition. TV is still working but It was time to upgrade to HD and even better 4K. I love this SONY 55inch TV. Put it together on my own and I am not a computer or tech geek. Picture quality so far after a week has met my expectations. I have yet to try something on 4K. so with HD and normal definition of 1080resolution on this tv I am speechless. Picture, tones and colors are amazing. I have been using PS3 for NETFLIX AND HULU and a Sony Blu Ray normal player. Nothing fancy or HD/4K on these and I have to say that I totally love the image. SONY has always been a leader on electronics and I would pay a bit more for something that I know will last and won't disappoint me and this totally exceeded my expectations so far. I will continue playing with it and try to find more higher resolutions movies and find 4K movies to see how much better those would be. But I know that I will not be disappointed. I paired this TV with a SONY Sound bar of 300Watts and surround sound with this bar is beyond amazing. I don't want to leave my bed (TV is in the comfort of my bedroom). TOTALLY RECOMMEND THIS TV AND IF YOU HAVE TIPS FOR ME I WILL TOTALLY APPRECIATE IT. I want to try to add on SLING TV service to see more movies and shows.

      Good Tv


      Pros Pic quality 4k hdr. Nice colors and a lot of settings. The blacks here are not so bad. sound is good upscaling decent motion great size big enough prize not too expensive and finance options cons: 1- aps. You better get a Roku streamer. This tv has a few apps, and not so good. 2- You can't play 4k hdr at 60 fps using any capable device. Let's say you have a roku streamer ultra, but the tv won't support the highest picture quality level of 4k hdr at 60 fps. It would play at 30 or 4k*without HDR* at 60. If you open Netflix from the tv app, you will have bad experiences in rapid scenes. You will have some pixels freeze all the time. It is not the wi-fi antena. The tv is just incapable of providing a smooth streaming experience at the highest picture quality. I may return it. 3- Can't pause live tv, nor record on USB. This is disappointing from Sony, since any roku TV can do it. I hope they enable this feature soon. 4-Stand looks weak.

      Really Nice TV For Gaming

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      I recently purchased this tv as I felt it was finally time to upgrade to 4K having recently purchased a PS4 Pro and owning a gaming PC. The TV is nicely designed and the stand that it comes with looks great. The interface is pretty good and has a fast response time, certainly a big improvement over my old 43 Vizio D series. However one thing to be aware of is that if you are a hulu live TV subscriber then as far as I can see the smart function of this tv will not allow you to use that service. To expand on this further there is no problem viewing normal Hulu however during the World Cup I was forced to use my PC as a primary player for the games I watched through Hulu live tv until I upgraded to a fire stick. For my PS4 and gaming PC I think the TV does a great job and for the price I am really happy, obviously compared with the technology that is available for $1200-3000 this tv does not hold up, but for anyone looking for a moderately priced 4K TV with a nice design and good picture this is a sound choice.

      Great Value for an Astonishing Picture

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      After doing extensive research, I purchased the 55" Sony x720e. This television met my expectations and exceeded them tenfold. First and foremost, the picture quality is absolutely stunning. The black levels are not that as an OLED, but are amazing for the price point. Color accuracy is on point and true 4K HDR content is absolutely breathtaking. Additionally, the motion is natural and extremely lifelike. I am still amazed seeing how natural fast moving videos flow flawlessly in a lifelike manor. Lastly, the smart platform on this television is top-notch. I have it hard-wired to my AC1900 router and the integrated Opera TV software keeps up with my operation pace. In conclusion, amazing picture and motion quality, 0% smart platform lag, and amazing input upcoversion make this an attractive and smart choice for a budget smart 4K HDR television. This set will leave you grinning from ear to ear. Worth every penny.

      Really incredible


      I purchased a TCL 55p605 last Saturday and the picture quality for 4K was unbelievable. I found regular tv viewing excellent as well. Where the TCL disappointed me was viewing sports. I attempted every tweak during calibration and between motion blur and the way the Fenway Park outfield appeared, it was returned today. I purchased the 55” Sony x720E and it’s just amazing. I don’t see any motion blur during sports at all and the color looks lifelike and realistic. I can’t vouch for user interface as I am using my Roku unit. There was very little tweaking of the settings during the set up. The TCL would be more geared to gamers and slower moving shows. The Sony is more versatile for my needs. Also if you haven’t experienced seeing nature videos via You Tube in 4K, your really missing something special. This Sony shines in everything it does.

      Great TV, bad stand design

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      TV is great, great picture, great quality overall wonderful. The only complaint is the TV itself has about a 4 inch back-and-forth give when on the stand. It does lean back slightly. It doesn't seem like the stand is big enough or sturdy enough for the size of the TV. Have read several complaints regarding this; it was a bad design on Sony's part. We even took the stand apart and reattached it, same problem. It just seems somewhat loose and leans back slightly. Two small rubber furniture cups on the back 2 feet seem to keep the TV level and propped where it is supposed to be. Shouldn't have to do that for an $800 television but it is a good quality TV otherwise.

      Excellent Quality for a Fair Price

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      When purchasing this Sony TV, it was between this or similar Samsung and LG 55" 4K TVs. Ultimately, I went with the Sony and I am very happy with my choice. The color, contrast, and sharpness of the image are all excellent. The colors on Samsungs are often so vibrant that it makes images look fake, and LG doesn't seem to match Samsung or Sony quality unless you buy the OLED models. My one note would be to not use Cinema or Gaming mode because it gives the picture a yellow tint that I personally am not a fan of, so I often leave the image settings on General for the best overall look. but if input lag is important for you, then Gaming mode may be necessary as I have found it to be in a few games that require precision timing.

      Disappointing Features

      • Verified PurchaserVerified Purchase

      My salesman turned out to be unknowledgeable about some of the features of the TV. My specific question regarding adding Apps to the TV was answered as 'yes, it can do that'. As the Geek Squad informed me, after taking time to call up an expert, Sony tells you what apps are going to be available and they will add them when they feel like it. I don't know that I would have purchased this TV had I known this. I went into the store looking for a Vizio that was on sale. I let myself be talked into this Sony one, only because I thought the sales guy knew his products. Well, this one didn't. I do have a Roku device which does fit in nicely and so I can access any app I want.
