Weird display issue on my LG Ultrawide

[aarh195]

I know my monitor is a little overkill for Windows 7, but I decided to whip out my old W7 machine and reinstall Windows on it. The display is borked. It works, but it is in a very incorrect resolution and it looks like the display is cracked. I finished installing Windows and tried to change the resolution. It wouldn't let me change it past 640*400. My monitor displays with a displayport adaptor outputting with HDMI.

Could I have had a bad iso? I've tried three different ones and all have the same issue.

Have you installed any drivers for the LG display?

Without the LG drivers, the EDID may not read from the monitor correctly. That means Windows doesn't know what resolutions are available. Try installing the drivers as HAVOC suggested.

That sure looks like a cracked screen in the pictures though...
