[QUOTE="Slurm, post: 327383, member: 27798"] My previous LCD (Toshiba 32WL56) had the same problem: I was only able to get 60Hz or 85Hz via D-Sub (75Hz gave me a totally shifted picture which even Powerstrip couldn't correct). HDMI and YUV was also possible and here I was able to switch to 50Hz but the picture was blurry and no fun to view. I finally sold it and bought me a new one that's able to view all needed RRs. And here I found a list of VGA Signal Timings [URL="http://www.tinyvga.com/vga-timing"]http://www.tinyvga.com/vga-timing[/URL]: As you can see for 1368x768 (the recommended resolution for 1366x768 displays) there's only 60Hz possible (of course a LCD could do more but that's not standard). SEALen uses D-sub where 1366x768 (at least with nvidia) is not possible. He's limited to 1360x768 or 1368x768 (the value has to be a multiple of 8). And his LCD doesn't support 50Hz over D-sub.
