Yes, and very nice controllers they are too.

The on-board video support is minimal. The CPU memory controller does
however provide a mechanism for loading the shift register of a bank
of video memories (VRAMs). A dumb frame buffer would require a modest
amount of timing logic (to tell the memory controller when to load the
VRAM shift register), a RAMDAC and the VRAMs themselves.
The other alternative is to plug in a PCI video card.
