Hi, I have "PE4C-EC060A V3.0" with "Dell D220P AC adapter". It works properly with my "Radeon HD6770" on my laptop "Dell latitude E5540" (Windows 10). I've changed the GPU to Nvidia Geforce 660 and windows detected it and installed the drivers, but is not working. If I plug and unplug the HDMI wire I can see that the monitor detect the HDMI connection but in the end is not showing anything and the monitor turns off. I checked the compatibility tables and I think that it should work: http://www.bplus.com.tw/Adapter/PE4C V3.0.html Any ideas? Thanks in advance.
