got a LG ultrawide for my office computer, but i can't seem to get 21:9 resolutions. I've upgrade the cable already to a DVI-D. Thoughts?
Which resolution are you trying to use, and are you using a Dual Link DVI cable?
Yes, I replaced the single link with a dual link cable. I would like 2560x1080 preferably
Ideally you need to upgrade your graphics card as the HD 3400 series is legacy hardware (and unsupported by Windows 10)...Have you tried with the Windows default drivers?
Install this driver (32-bit | 64-bit) and show me your available resolutions list.
