I recently upgraded to a Macbook Pro 15" with a mini displayport, and I decided I would share my LCD monitor with my windows box. The desktop box is connected with DVI and I have connected my Macbook through an HDMI adaptor from Moshi. Everything works very well, and I'm pleased with the quality of the output, but I'm having trouble with a screen flicker in full screen games. When I select full 1080p (1900x1080) in any full screen game, the screen "shudders." It does not occur on the OS X desktop, and I can only explain it as a shudder. Lines and text shift perceptively left and right, and the game is unplayable. I have experienced this problem in Starcraft 2, World of Warcraft, and Half Life: Episode 2 so far. Could the problem be with my monitor and the way it handles an HDMI signal? The Macbook is flawless otherwise, with no other issues of any kind. The "shudder" only occurs during full screen games set to 1900x1080. Lower resolutions are not effected and work fine... I'm stumped. Edit: I should add that I have no other 1080p capable devices to test the output with.
