Hello,

Thank you for contacting us here on the forum.

Based on your description I would recommend testing different resolution modes.

Mainly, please add 1360x786 first and then 1368x768 and test it on them. In order to do it, please take a look at this article. Article describes a general change for VGA.

In your case it should be probably:

DVI-I-1-1 (DVI- xxxx) and probably
gtf 1360 768 59.9, the rest accordingly.

Mode name should stay custom.

If you follow this link you may read more about this issue.

Thank you for your actions, in case of any questions please let me know.

Best regards,
Jakub
