I have an older Dell 24" monitor (model 2407-WFP HC) manufactured in Nov 2007. I have it connected to the UD-3000 via VGA to HDMI adapter. My laptop is an Acer Aspire S7 (model 391) running Windows 8.1. The monitor is connected through the UD-3000 to my laptop and I am experiencing constant screen “blinking” issues when the lid to my laptop is closed, and less frequent (but still intermittent) blinking when the lid is open. Display is set for “duplicate” and power option is set for “do nothing when lid is closed and plugged in” (that is, do not turn off, sleep, or hibernate).
Previously, I had the monitor connected directly to the laptop via VGA to HDMI-micro adapter. My display & power settings allowed me to view the external monitor when the lid of my laptop is closed as well as when it is open in the same settings noted above. I have downloaded the most recent driver and rebooted the laptop. Suggestions on how to fix? Or is it simply old monitor compatibility issues?
