Help, 2nd Monitor detected but no signal
Hi I bought an Asus PA238q (1920x1080), and while the monitor is detected by Windows it just keeps saying that no signal is detected.
I've used HDMI through the motherboard, changed the source in put to HDMI but no signal is detected. The HDMI on the motherboard to my primary monitor works completely fine even with the GPU installed. I've also connected the Asus monitor to a Lenovo Flex 14 but again while detected there is no signal detected on the monitor.
I disconnected my primary monitor through DVI and connected that cable to the ASUS monitor - on the DVI input no signal is detected thus no display (GPU is GTX 580 1.5gb Palit Reference).
I've tried VGA with another laptop, and that works perfectly fine.
The only port I haven't tried is Displayport
Note: All ports work fine on my primary monitor and I haven't had both monitors running through the GPU and the "extend desktop option" is also chosen.
I don't think the monitor is broken, it's detected by the OS and VGA works. It's just the on other inputs the monitor doesn't detect a signal. Does anyone know what I can do?
