  • Purchase on sale, older model
    Verified BuyerReviewed by User42069 - December 12, 2020

    Got it on sale runs 4K at 60 Hz no problem, great for next gen gaming. However, does not support HDMI 2.1. Therefore, does not run 4K at 120 Hz. Other than that, great tv. HDR picture mode dims the screen according to picture brightness/contrast when watching tv, so I use vivid. Also has a low-latency gaming mode. If you plug a cable box into an hdmi port while the tv isn’t on that input, you won’t be able to access the Home Screen. Unplugging the cable box from the tv solves that problem. Make sure to plug the cable box’s HDMI into the desired port while the tv is on the corresponding input. Also very easy to install onto a wall mount.

  • Decent for the price
    Verified BuyerReviewed by Benjaminstory94 - December 4, 2020

    This TV is decent. We’ve had it for about a month now. It regularly disconnects from our wifi, so we have to go into the settings and reconnect (the router is only 10 ft away so it isn’t a connection issue). Also, when using some streaming apps, the app will freeze up. You can’t even return to the Home Screen. The only way to get it back is to go to settings and force close the app. The picture is nice and crisp, but the screen is pretty reflective so we can’t have the lights on if the scenes are really dark. I didn’t pay much for the tv, so I’m not too upset, but if I were to do it again I’d probably spend a little more for a little higher quality

  • Great for the Price
    Reviewed by  - December 16, 2020

    I had bought the TV recently on sale for $399. It was a bug step up from a non smart tv to this. The TV itself has a great picture despite being so cheap. Obviously it's no QLED quality as it being an LCD screen but all in all, this is a great TV if you're on a budget. However I did run into a problem. There is no sound coming from the speakers when I'm on my bell box. It's pretty strange. I'm waiting on a adapter to use my surround sound, so it should be better (hopefully)

    Yes, I would recommend this to a friend.
