I had two monitors connected to my PC (dell T3500), I tried to upgrade the RAM, then after restarting the PC, the Acer 240 monitor start saying that the "input not supported" with an hdmi cable (PC output is display port). It only works with DVI cable. I tried the resolution, etc. Somehow Acer doesn't like HDMI connection. Any suggestion would be appreciated?
