Great TV so far!

I've had this TV for a couple of weeks now. Seems to work well so far. I got it on sale for around half off and couldn't pass up the deal! Colors are great, picture is beautiful and very crisp at 4k. HDR works perfect on Xbox one X. Response time is very good too, with gamer mode on I was able to play SNES classic games like Super Mario world with no lag at all. Roku is a nice touch if you don't have a PC or gaming system to watch YouTube and Netflix, built in Wifi works great too! Nothing bad to say about it so far, hopefully it doesn't break down on me. Only thing I can think of that was a bit annoying was the learning curve on the menu and settings. It took me a little while to learn that you need to enable HDMI 2.0 on each individual input if you want them to use certain features like HDR etc. Menu not as user friendly as it could be, but I was able to figure everything out, so it's a minor complaint.

Great almost downgraded to good

I have to say almost great. Would have given 5 stars but the smart feature of roku is very limited. There are key features i have a hard time understading with this tv there is supposed to be motion control i have yet to see a setting to utilize this feature Also there is no bluetooth control. but the app for the phone is nice. Having some trouble using the screen mirroring. Cant seem to get it going on my compatible laptop. But overall the picture quality is great! the youtube streams in 4k a huge plus. And the connection runs on the 5Ghz range! that huge deal when it comes to connection for wifi for me. Although i wish roku had more selection for apps, its very limited.

Really Good Budget 4k Roku TV

I had to buy this quickly in November of 2017 after my 8 year old LG Smart TV started acting up. Found this on sale during Black Friday, ordered online, and had it the next day. The Roku Video app plays most of the content streamed to it from my PC, and it's really nice having Youtube on the TV. Picture quality is great - and the 4K sources I've tried look breathtaking. Warning - this TV doesn't have a very good field of view, and looks best if you are watching from directly in front of it. So after using it for nearly four months now I am very pleased.

Good for the money

This TV is pretty good if you're planning to sit right in front of it most of the time. I picked it up at a decent price on sale. The Roku interface is pretty good, runs smoothly. Good picture quality. I'm happy with it. If you're looking for a TV with wide viewing angles, skip this one. The colors and contrast will wash out as you move to the side.

Buy It, you won't regret it!

This Sharp tv is amazing, the resolution is amazing. The 4K is unbelievable especially noticeable with Netflix. You don't be disappointed with this tv, buy it now!

The resolution on this tv is amazing, very sharp! The Roku interface is great and easy to navigate. The NHL app comes with the tv so that’s great for me, I’m able to stream games with Rogers Live through the app. Everything was a breeze to setup, very straight forward. You won’t be disappointed with this tv!

great display and features for entry level 4k

PROS no dead pixels great smooth roku interface tested HDR working with full 4k resolution (you will see an HDR icon in the top right corner) decent speakers nice slim bezel has an RCA input for older devices, missing on many 4k displays CONS not compatible with dolby vision roku interface is great but webos (lg) and android tv (sony) are more useful volume on the SIDE of the remote control?? this is a sharp branded hisense display but that doesnt bother me. all that matters is the picture and this tv is GREAT for a non oled 4k uhd display 9/10

  • from North Bay, ON

Amazing quality half the price

This TV is amazing for movies or streaming online by far fastest TV for streaming and gaming had no problems best buy really gave me real facts and education things I didn't know about TVs in stead of selling me something that cost more this TV is amazing I would recommend it to any one who wants a TV with stunning technology and amazing quality for half the price all you need is a home theatre system and your set

Fabulous Value, Quality Product

Super great sale price, fast setup with very easily navigable menu system. Great to have Netflix button on remote (though it would be nice to be able to program the 4 content buttons), and lovely to have all of our devices (AppleTV, PS3 and PS4) so easy to access. Picture is BEAUTIFUL and has many customization settings to please everyone - and you can customize the settings per device, which is really smart.

sharp tv 50 inch Roku

Bought this tv in 2015. Its now 2017 and the tv is already not working. Tried troubleshooting with no success. Spent timeless hours on phone with Sharp Tv with no luck. Had cable guy come in twice because the wifi would not link to the tv. The tv shuts on and off while watching programs and no Netflix because the wifi wont connect to the smart tv. I didn't purchase warranty thinking the tv would last at least 5 years before seeing problems. Will never buy a sharp tv again!! Only good quality was the picture was nice

  • from Delta, BC

It broke down after 16 months.

After 16 months and watching it less than 10 times, it will no longer even find a network.. and I have 5 g wifi... and it restarts every 2 minutes reducing it to junk status. Best buy won't fix it and the tv repairman refused to fix it and said it was Sharps problem. I got burned period. I will never buy a sharp tv ever again.

Best Bang for the Buck

Note: Not mentioned in the product info is that this TV includes WiFi and an Ethernet connection. Either can be used. The picture quality is excellent for a TV in this price range and the ROKU platform is amazing and easy to set up and use. I recommend it....Great TV.
