TV is great!

TV is perfect. Doesn't have any weird juttering like some of the more expensive 4k Tvs in the market. Also its has a smooth picture to pixelation.

You get what you pay for and I paid a good price

For what I paid (open box) I can't complain at all. No its not 10 or 12 bit color but picture is very nice. Up convert does well. I played true 4k from youtube and blew me away. Considering that a good 1080 tv costs more for intro to 4k you can't go wrong. No it's not perfect but it is stunning. Don't buy this and expect a 1000 plus comparison you will be disappointed but compare it same range it's as good or better.

  • from second ?? to the left and on till morning..


my last review I was happy with this TV... update... after sitting watching the TV progressively turn itself off and on more and more often I decided I'd rather get rid of this panel. the picture was great and I loved the Google cast function but Toshiba no longer mean quality. just wish I'd read the other reviews before buying it. avoid at all costs less you get the ?? I got.

Blurry screen

Tv screen become blurry after a week. Toshiba came to try fix it but the screen wasn't blurry at that point, obviously after the individual left it went blurry. Avoid at all costs.

Utter garbage

Tv became blurry after 2 weeks and then shut on and off, Best Buy replaced tv hassle free and the new tv had the same issues after 5 days. Tv goes blurry and unwatchable

Not Impressed

I've had a few issues with this tv. First is the screen, there is a noticeable line across the bottom of the screen. I've adjusted the settings and as long as it's not a dark background then you can't see it too much. Second is the sound, it's okay but it could be better. Some channnels sound fine but others are so quiet I have to turn up the tv and the PVR really high. Now the tv has started turning itself off and on and it's becoming more frequent. The screen is pretty good but you don't really notice the 4K too much.

Not worth the money

I bought this tv thinking I was getting a great deal. The reflection on the tv is very annoying. I've had to move all the furniture around and basically only have one lamp on because the glare is so strong. The description of the tv misleads you. It's doesn't have wifi built in. If you have a chromecast app then you can stream to the tv from a device. While it does connect fast to chromecast, the apps are very limited. There is also an annoying white line across the bottom of the screen. You can't see it when the screen has light colours but if it's a chalk screen then it's all you can see and focus on. This is a very entry level 4K and I haven't really noticed the difference.

Completely met expections

This TV has perfectly met our exceptions. Comes exactly as advertised, we are very happy with picture quality and the chromecast capabilities. Haven't tried it on any 4K material yet but just the quality itself when watching HD cable and Netflix is stunning enough.

  • from Edmonton


Don't buy!!! Image became blurry in 2months and was told it might take up to 60days to either fix or get a replacement!! Don't waste your money!! Toshiba is just crap

Good TV

It is a good TV, great picture, perfect size. However, it can't seem to find movies on the USB when inserted, when my Sony TV had no issues.

  • from paris, on


so far so good, picture is fantastic sound is pretty decent for a fat screen. only thing I might complain about is the different picture modes, I think the processing leave a slight delay between the sound and picture resulting an out of sync audio feed. easily sorted by changing to the PC or GAME mode ..
