Is it normal that when you connect a GPU to a motherboard, the video output from the motherboard connectors disappear, and only the GPU connectors give the video output?
This is relevant to me because my motherboard has a good old VGA connector whereas my GPU only has DVI/HDMI and modern stuff, and the cheap, cheap screen I bought only has a VGA connector. And GPU doesn't even ship with DVI-to-VGA adapter...
SPECS (although this might not be so relevant):
Motherboard: Gigabyte Z77-D3H
GPU: Sapphire Radeon HD 7950
Screen: SAMSUNG SyncMaster S22B150NS (which is quite -let's say- basic...)
