Hi,
Ok another problem with the new PC. 780 graphics card and iiyama 27 inch display. tried both the DVI outputs but on both outputs when i set the native resolution (2560x1440) i get a very poor image, text is unreadable and looks missing! although at this res games play perfectly. when i down the res to 2048 x1152 image is great.
First shot at native res, unreadable, second shot lower res clear pic
see screen shots
