Issues getting DVI monitor running on new PC
I'm knee deep in the standard parental support duty.
The PC is based around a Haswell mainboard - Asus Z87-K. HE does a chunk of photography work and has a high res screen, and I figured the extra oomph in the 4600 couldn't hurt, allowing him not to need discrete graphics.
However I'm struggling. His monitor is a Hazro HZ27WC. This has only DVI, and when I hook it up, its not giving me a picture. However the power light goes solid and I'm seeing the backlight come on, so it does seem to be detecting a signal. If I then connect a standard monitor via analogue VGA, that comes up immediately and the power light on the Hazro starts flashing.
If I then go into the display config screen in W7, its showing both screens, but the options on the "Digital" display are all greyed out.
I tried swapping across the GPU from his old PC, but I'm having no luck there either.
I am sometimes seeing the W7 boot "progress bar" come up, but nothing more.
Now I know the Hazro lacks a scaler, so I'm not sure how well it plays at other resolutions outside native. However as I can't seem to change the settings in dual screen mode, I'm a bit stuck.
Its been a few years since I did serious PC Support, but I like to think I can work through most issues, but this one has me really stumped...
Anything obvious I'm doing wrong?
