I have a Dell Optiplex 7040 with dual R5 340x adapters. I can't get the resolution to 4096 x 3112. This resolution is not even an option. The max that is in the list is 1920 x 1080. I have a 4k TV and want to use it as a 4k monitor.
This question should be directed to Dell. This card is sold as an OEM model from Dell.
The Card itself can support 4k but Dell may be preventing it for some reason.
Requires 4K display and content. Supported resolution varies by GPU model and board design; confirm specifications with manufacturer before purchase
