I have a SwedX FHD or UHD or something screen, not 4K.
The remote is simple. The menus are simple. Turning it on could be quicker, but is not horrible. The sound is not great, but functional. It has digital audio out, so I use an external amp and speakers.
The price is quite nice. The lack of any "smart" features even nicer.
All of their screens come in a "TV version" with a tuner, and a "monitor version" without one, but are otherwise identical.
The speakers are pretty crappy, but that's to be expected.
(European company, so not sure where they ship to outside the EU)
