So, i want to render at a higher resolution than what my monitor is able to do (Samsung SMBX2235 1080p) and i don't really understand how to do it. I start CRU, it already has a detailed res defined (native one i suppose) so i add a new one. I use the auto standar LCD timing and a ****x**** res that is higher than 1920x1080 (and is 16:9). No matter what res i setup there, after restart i still can't see it / use it. What am i doing wrong?

CRU is not meant for that:

• This program adds monitor resolutions, not scaled resolutions. Lower resolutions will be scaled up if GPU scaling is enabled, but higher resolutions won't be scaled down by the GPU. Higher resolutions will only work if the monitor can handle them.
  

Assuming the monitor can handle it, you'd have to patch the driver:

• Single-link DVI and HDMI are limited to 165 MHz pixel clock unless the video driver is patched:
  • AMD/ATI Pixel Clock Patcher
  • NVIDIA Pixel Clock Patcher
    

Even with the patch, you'll have limited success because single-link DVI and HDMI are not meant for high resolutions.
