Where do I find this extension block? I am using windows8.1 64 bit Now I am trying my last option, HDMI to DVI. So I tried a HDMI to DP to see if I can use the DP port, same problem and message. u2711 seems detects cable is plug in, but pop up a screen saying no signal from your computer blabla. Long story: For whatever reason, I always get no signal in u2711's HDMI port. My HDMI should output 1080p, I tested it on another full HD monitor and works using HDMI. Short story: using hdmi to dvi adaptor (I also have a hdmi to dvi cable, but it is single link), both only give me 1680x1650. Is there any other settings I might need to change? Or would it be helpful to post any other screenshots? I checked and I do have an HDMI data block in the extension block (screenshot: ), and so I installed the patch and then redid the custom resolution and restarted the drivers, but it's still not giving me a higher resolution.
