My setup is currently a 1280x1024-1920x1080-1920x1080, the small monitor is an acer and the two big ones are both asus. So recently i have had the problem that the monitor on the far right keeps losing signal, it turns black for a few seconds, then it comes back on and the HDMI source logo thing comes up on the page. It happens a few times in a minute then it stops for a while then it usually comes back.
If there is anymore information i can provide then please say so. ASUS VS248H-P Black 24" 2ms HDMI LED Backlight Widescreen LCD Monitor 250 cd/m2 ASCR 50,000,000:1 - Newegg.ca
