Hi folks. I recently upgraded my monitors from 2 x samsung 19" syncmasters to 2 x LG 24MP55. One uses hdmi the other vga on a GeForce 210 1GB at 520mhz. My issue is that from time to time (once or twice a day) my monitors will loose the picture for a few seconds then when they come back on, either the windows that are open will seem to resize (sort of how things do when the resolution is changed) OR one monitor will totally disappear and I will have to reset the "connect to external display" settings to kick the second display back in to life. Would anyone think that is a monitor issue or an issue with the graphics card?. Monitors are running at 1920 x 1080. Cheers.
