I've been using this as a monitor / TV combo. It works great as both. Remember WebTV of old? This is the new version. Ha. Except the Web part is via PC and HDMI. The PC can also act as the TV software source (for example, Spectrum TV streaming via the browser). I also use it for other PC work and Tidal streaming.
The TV includes its own set of apps as well, some paid, some free. So overall it has been great for binge-watching during the pandemic.
The software could perhaps be a little more user friendly and snappy, but hopefully with future updates improvements will be made. The included remote is decent quality and does its job also.
The picture / video quality is fine, although I did adjust each source according to my preferences. Keep in mind the only way you'll see the kind of quality demoed in store is if you watch 4k video with a lot of colors. Don't expect every show to be broadcast with that kind of eye popping resolution. The 4k screen will reveal flaws in lower quality video similar to the way high quality speakers reveal flaws in music sources.
I have the TV connected to an amp/speaker setup via the optical connector as the internal speaker is basically good enough for speech, but not so much fornsound effects and music. It's enough for you to listen to the dialog as expected.
Bought it a month ago. I like the quality and all the features. The Watch Free that comes with the TV is a pleasant surprise being able to watch oldies and newly released. At this point I can’t even remember what cable is... Con: it delays when update is needed and there is no alert letting you know. You just figure it out when you are wanting to watch your favorite TV show. It also cuts the sound out sometimes or delay the volume when trying to stream through fire stick (not a huge concern for me to give it a poor rating) I love my TV
