The card: XFX Radeon HD 5550 The screen: LG Flatron E2240S 21,5" The results: The system have a nice boot but seems that you work today show some different results from yesterday: * Vivid colors :P * The Resolution seems correct (1920x1080), but have dozens of buzzy horizontal scanlines (like a TV channel out-of-sync), So, nothing is readable.. For me, the best option is use 1280x960 failsafe mode for now I'm looking forward for your greate progress here :) Thank you! Michael
