Smeared colors on OLED

Hi

 

I have a project where i use the AD9398 in combination with a DAC to show a PC screen on a small OLED. My problem is that powerful colors smears or creeps vertically on the display. If I, for example, have a black background with yellow and blue obstacles/icons, the blue, especially, gets smeared and continues all the way to the bottom and top of the screen and that way interferes with the other pixels, in other words, the powerful colors continues upwords and downwords on the screen when they shouldn't. Any idea why this happens, the display itself is OK, since it works fine on a totally different graphics card, a reference card using different HDMI receiver.

Thomas
