I have two manga screen 2(big one).

I have two manga screen 2(big one). Fancy item, very nice!! I guess the native setting of the fancy one is portrait. That’s my problem. I want to use the fancy one for commercial CCTV screen (HDMI output, 1920x1080). But I cannot rotate the screen because there is no menu for adjusting screen in CCTV. Is there any way to solve my problem ?

Hi… What operating system are you using ? Or is it straight out of the CCTV box ?

It’s straight out of CCTV box
