[NAME] Thanks for your advice and the deep insight into the indirect display tech. Pretty interesting but not an option for me. I finally found a solution. I was on the right way by trying to set a custom resolution in the Intel Display Settings Panel. I just had to tweak the settings a little bit (timing method). You'll find great instructions here: [URL] The instructions for Intel HD 4000 fixed the problem and I can finally use 2560x1440.
Hi, I'm trying to connect my Dell Inspiron 17R SE 7720 to an ASUS PA278QV monitor which is capable of 2560x1440. However, the Inspiron let me only choose 2048x1152 as the highest resolution.  Does anybody know if  a) the Inspiron HDMI supports 2560x1440 and b) if not: is there any other solution to get this resolution with this laptop? (only VGA and HDMI) I already tried the hack with that user-defined resolution in the Intel Graphic Panel (at 40Hz). Unfortunately, it did not work (monitor error message: Out of Range) Hope you can help me with this. Thanks,Elisabeth
