Hello,

When I switch the display to the projector, the image is split in two, with the left side appearing on the right and vice versa.

COMPUTER: Asus TUF, with NVIDIA GTX 1660Ti managing the HDMI

PROJECTOR: Acer

SEARCH:

When I set the display to 4K 30 Hz, it works fine. At 1080p, 60 Hz, it’s good. The problem arises at 4K 60 Hz and 50 Hz.

I have another computer, I tested it, and 4K 60 Hz displays correctly, so it's not the projector's fault.

I’ve done all the updates for the graphics card; it hasn’t changed anything.

Conversely, I uninstalled the graphics card driver, started from scratch, reinstalled the driver, and it didn’t change anything.

I’ve been searching for my problem online for several days, but I feel like I’m all alone.

If you have any ideas or leads, I would appreciate it.

Thank you, best regards.

    Hello, a first response but I’m stating the obvious: filming in 4K is often limited to 30Hz on a camera. I don’t know the source of your clips; I think the graphics card doesn't manage 4K.

      Hello. My other computer displays 4K 60Hz well with a small AMD card. So, does the GTX 1660 Ti not support 4K 60Hz?

    Hello, I would be very surprised, of course. I have no other leads other than to check with Asus support, sorry.

    Hello,

    So I found a solution by changing the color format.

    I had the problem in RGB. And by switching to YCbCr420, I no longer had it.

    Hello ???? thank you for the feedback, it has helped reduce the bandwidth in luminance of the color-related information, good catch
