There is a gap between the black frame and the LCD screen of the display. It is about 1MM or so. There is no fully contact with the LCD screen. Is it normal?
Normal that monitor belongs to second line product commonly, use at ease
What brand do you want to see?. Second line brands can be accepted. A line of brands is unlikely to happen
No problem. This is called the art line. The second line brand art line is around 2MM
