A method for implementing edge blending between a first and second video frame to create a seamless multichannel display system. The method is implemented in a graphics computer system including a processor coupled to a memory via a bus. Within the computer system, a first video frame is rendered for display on a first video channel. A second video frame is rendered for display on a second channel. A first overlap region is rendered onto the first frame to obtain a first blended video frame. A second overlap region is blended onto the second frame to obtain a second blended video frame. The first blended video frame from the first channel and the second blended video frame from the second channel are then combined such that the first overlap region and the second overlap region correspond, thereby forming a seamless junction between the first blended frame and the second blended frame and implementing a high fidelity multichannel display.
