    Calling all IT pro's.

    I just bought the DELL S2440L 24" monitor but facing some issues.

    If I go to max resolution 1920x1080 the screen has black lines flashing on it and every few minutes the screen goes black for a couple of seconds then comes back.

    I found if I lower the resolution to 1280x720 there is no problem.

    I am connecting via HDMI because my monitor only has VGA which my graphic card has only DVI which is a ATI Radeon HD 5700 series.

    Here is the video

    Any help appreciated!
