GV-R795WF3-3GD graphics card, Dell U2713U monitor at 2560 x 1440, whenever the graphics card GPU appears to be exercised, a good portion of the screen appears to have a blue tint to it. This can be reproduced using 3D Mask v 110 software. This occurs with 2 different brand new Dell U2713U monitors - so I don't think it is the monitor being the problem.
Blue tint does when using a smaller monitor on same computer system.
Blue tint also occurred with beta driver version 13.6 beta2.
3D Mark version 110 software - just "run all tests" and you can reproduce the issue.
