Hi I just bought my first custom built machine.

I have seen discussions related with displaying using dedicated GPU. I am considering that my VGA might be incompatible with my motherboard. Since the VGA is not being detected within the Device Manager's Display Adapter.

Motherboard: Asus H81M-D H81 LGA1150 DDR3
VGA: Sapphire R7-240 1gb DDR5 128bit

When a PC has a grpahics card plugged in, the onboard graphics of the CPU is disabled. Your graphics card should have an option for VGA, HDMI or DVI. :plug the monitor cord into 1 of those on the graphics card, it will be towards the bottom of your case on the back.

I am using a VGA cable to attach on my plugged in graphics card. It only shows a blank screen.

When I remove the cable from my graphics card and transfer it to my motherboards VGA output, my screen shows the right image.

I agree, this is a common issue. There are a lot of resources for this, I tried some of them but it didn't work.

I tried disabling the intel driver from the device manager and rebooting, but the screen is still blank when connected with dedicated GPU. Connecting the VGA cable shows the screen again.

I tried reinstalling my OS, and reinstalling the chipset driver, same issue. Blank screen and defaults on onboard GPU

I tried installing the Catalyst Software suite but it doesn't pass the Install Manager. I'm not sure if this affect anything, but the graphics card is not seen in Device Manager -> Display Adapters. I'm afraid the either the PCIE is dead or the Graphics is dead.
