Peace be upon you. I have a Chinese screen from the Teleizon company, 50 inches in size. The screen supports 4K with an LG operating system and has a built-in receiver. It comes with two remotes: one remote supports a mouse and a regular remote. Praise be to God, the screen has been with me for a year, and I have not complained about any hanging or maintenance, praise be to God, and it is guaranteed. 600﷼
