Limited Viewing Angles and a Pain to setup HDR for Xbox One S

Pros: Picture quality was great for the price, and right amount of HDMI ports, and Roku is a great interface (despite the spotify app being garbage) Cons: Audio hiss if you use headphone out (powered on or off and using a decent cable), I used optical instead and sounds fine. Viewing angles are kind of poor, with about 100 degree sweet spot. Other: Advertised as HDR and worked fine for netflix, when booting up XBOX one S it does not recognize HDR unless you go into the tv, settings then select the input your xbox is on and manually select HDMI 2.0 instead of Auto, there is no where online that tells you to do this but with some tinkering I figured it out. Rebooted tv and xbox and works like a charm and looks decent too

So Bestbuy advertised this as an HDR TV, but it does NOT support this whatsoever. Do not buy this just to play HDR games with your Xbox One X. Check the TV's manual first, don't rely on BestBuy's description. I'm going to return mine as soon as I can, and spend money on a better TV.

Amazing tv for the price

Its worth it

  • from Montreal, QC

Very good TV, nothing to complain about

This TV is exactly as described. Most importantly, everything works as expected. Roku is also pretty nice.

Good value

For the sale price it's good enough value. Picture quality is great straight on not so much at angles more than 45'. Also no matter which picture size I choose it doesn't include writing at the very bottom ie the news channel! It's my first Sharp purchase - I rate it a strong average!!

Felt like I needed to wear glasses while watching tv. Even the menus were blurry. Do not recommend. Returned and went with a 4K LG and it's MUCH better.

Double Duty Display

Works great as a combination small TV and big computer monitor. No complaints with the picture quality. Roku is solid. Love the minimal controller. For the nerds: -x264 mkv works -x265 mkv works

4K and HDR is nice, but off axis viewing is poor

First impressions were positive (except the TV requires a PC and internet connection to setup your Roku account) 4K resolution is nice, and HDR does work. Confirmed with YouTube HDR and PS4 HDR settings. TV switches to HDR mode and acknowledges HDR signal with a badge in upper right for 1 second. Roku interface is quick enough and loading app performance is good. My issue with this TV is the off axis horizontal viewing. It is a VA panel, which does give good contrast and colours when viewed STRAIGHT ON, but move more than 30 degrees off center and the picture gets noticeably washed out and it's a noticbly worse experience than my old 1080p IPS panel TV. If you are watching in a straight on it's an impressive TV for the price, but the off angle wash out may cause me to return this.

So far I've very pleased

Given the sale price. I cant fault it in any way and I find the operation as TV or computer display working great. No issues.

Great Value, when on sale!

This is my 2nd 4K HDR TV set which made me very particular in what I picked up for the bedroom having a SONY XBR 4k HDR 55in as a reference point in the main living area. The key to finding out if you have a great set or not is going through a calibration and having good source material to use. Having 4K HDR blurays, XBOX one S and a PS4 Pro as well as my gaming PC as my source really helped me put this set through its paces. Going through several movies, games and several days of having it in the living whilst I tested for colour accuracy, clarity, and response times. I have to say that I really became impressed with the clarity and colour of this display. I was skeptical being an exclusive with the partnership (more on that later). Everytime I loaded a game or a movie I was excited as I saw how the TV would display my content. The picture was bright, it showed great detail, great response time for a TV if your a gamer (16ms@4k). What was lacking was the accuracy with HDR content. This isn't a surprise as HDR is still new technology and the higher end sets tend to be the ones accurately reproducing a scene. Gaming HDR content was accurate with this said. When I would pull up Ratchet and Clank, the Last of US, Horizon Zero Dawn. The picture would have me sitting back being impressed. When you would put in a 4K bluray or Stream Netflix. I was left looking disappointed as the wide colour gamut, difference in contrast with the light and dark areas of the set didn't have the pop I was used to. Being a Best Buy/Sharp partnership with Sharp overseeing Best Buy produce and manufacture the set. Sharp licensed its name to Best Buy to produce this TV's over the last few years. My reservations were set as I wasn't planning on keeping the TV if it didn't meet my expectations. At this price point I wasn't expecting much. Considering it ended up exceeding my expectations for what my intended usage is going to be, which is being in the bedroom I am very pleased. This is a great TV to pick up when it's on sale. Would I have picked this up if it wasn't at the regular price? Very unlikely as TV's priced more than this would be a better choice as a primary set. In closing this Sharp TV being a non Aquos not being a Sharp produced unit offers great value, great picture quality and good for gamers. Pro's - Great Value on Sale - Bright Picture - Good as a 2nd gaming set - Roku which makes app switching quick! - Good colour accuracy - App control iOS and Android - Design. Con's - HDR accuracy was spotty depending on source . Gaming sources were great, Netflix wasn't so great.

Very nice TV at great price

Purchased at Boxing day sales and very pleased. Excellent picture. Hooked up well. Roku is interesting to explore. Size was just right for the location. Five stars!

  • from Brossard , QC

It was the 3rd model I tried, and the best.

Tried three different models, this is the one that gave me the best picture and also ease of use as a computer monitor, extremely satisfied with the picture quality.

  • from Brampton, ON

I purchased this TV on Labor day sale and have to say it works great. Good for the price considering 4k and Roku is fun to use. I high recommend this!

  • from Red Deer, AB

The TV exceeded my expectations. Roku smart feature is user friendly. For 449 dollars, this is one good deal.
