    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 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.

    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.

    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.

    Great purchase!

    • My Best Buy® Elite MemberElite Member

    We purchased this tv as an open box item with gift cards and reward dollars that were expiring soon, so we didn't do much research or overthink the purchase. We knew the basics that we wanted, had a budget, and the manager of the night was extremely helpful and helped us make a great purchase! Even as an open box the item was brand new and looked as if it had never been put together or used. Set up was very easy. The footstand is flimsy by itself, but once applied it is super sturdy. Set up with our cable was very easy. We followed the prompts and had no trouble. The remote could use a redesign as the Select button is small for larger hands. Otherwise, no issues. The hubby is happy and we didn't break the bank. Would definitely recommend.

    Awesome Picture & NO APPS (CR@P)

    • My Best Buy® Elite MemberElite Member

    ***** Picture, After several consideration I decided on another SONY Brand, I bleed SONY, however DID NOT expect in 2017 to have a TV with NO option to add my APPs of my choice. Me being overseas APPS are important, not the pre-loaded garbage others paid Sony for it. I would Fly back to New York and pay the extra $150.00 air transportation fee just to return this TV to the Best Buy store, I have older Sony models with ALL my APPS of MY CHOICE... GREAT PICTURE NO FLAWS, RECONSIDER IF APPS IS SOMETHING OF IMPORTANCE TO YOU.... :)

    Best reds and blacks for the money

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

    I bought this TV recently after looking at a comparable LG and Samsung. I spend the extra $80 due to the color. One thing I always look for is the reds and the blacks because those are the two hardest colors for a TV to produce. This "budget" Sony had way better red and black than the other two. The apps on this tv are lacking significantly vs. the LG and Samsung but it does have your main apps such as Youtube, Netflix and Aamazon so if that is all you need this TV will be fine. The sound is okay but it is a flat screen so a sound bar is needed if you care about sound whatsoever. Overall I am happy with the tv.

    Sharp picture, w/excellent contrast and color

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

    Easy, semi-automatic setup.Only has three HDMI inputs, and we had four devices w/HDMI output. Problem solved by getting a new A-V receiver. Sound from the built-in speakers is marginal; but was much improved with surround sound and Dolby 5.1 from the receiver, when the program source is available (broadcast TV / cable in our area is only stereo, not 5.1). But blue-ray discs and Netflix or Apple TV streaming sources are frequently in 5.1, and the sound is superb. Have not tried the "Smart TV" components, since they basically duplicate the streaming I get from Apple TV and the BlueRay player.
