I have bought it to use as a dumb TV, to be driven by Nvidia shield!
Surprisingly, the TV performs acceptable with its own software.
This is my 3rd Vu TV after 55", 43" and this 75"! (All of them are still working! as dumb displays)
About this model, The display, VRR, 4K 120 works without any issues, matching the top 3 brands.
Pros:
1. Really good display for bright viewing environments.
2. UI is responsive and nearly all the apps I tried work.
3. TV and remote build is excellent.
4. After sales support is good. (See below as well)
But this comes at corners cut! (I won't say this as Cons factoring the price I paid)
1. Local dimming zones are few! Dark room watching is certainly not recommended.
2. Software is not upto mark! Old android and No updates (Still none for my 55" which is 6 yrs old)
3. Sound system is nowhere close to the advertised values! Get a sound bar or HT.
4. VRR and local dimming doesnt work simulataneously!
5. After sales support is limited (Its awesome with what they can do! anything above results in 404!)
Best!
