Cannot get monitor to display at native resolution

[cokewithvanilla]

Hello, i Have an LG E2340. I just removed this from someones computer to install 4 monitors. It was running at 1920x1080. I am running it as a fifth monitor on my computer. I have intel hd 4000 onboard graphics. I also have three displaylink usb > dvi.

if I plug this in as the ONLY monitor to my docking station under intel graphics, I can get 1920x920 by creating a custom resolution... any more says it exceeds the bandwidth.

If i plug it into the displaylink, i get 1680x1050.. which is the max resolution this thing can push.

So, displaylink adapter isnt an option. How do I get the intel hd to do what its supposed to??

Intel claims their HD 4000 can support 3 simultaneous outputs, that's only possible when using 2 pixel clocks. This is because they only included 2 pixel clocks in the chip-set. Display Port can support the sharing of pixel clocks, otherwise you're going to have to supply matching displays for the setup.

This happens with only one monitor connected

Try auto adjust on the monitor
