I want to achieve a resolution of 3840x2160 in games. I'm able to input this resolution in the CRU tool, but I've noticed (in the tool) that at this res, my pixel rate jumps up to over 500MHz.

This program is not intended for downscaling. The Samsung T260HD is a single-link DVI/HDMI monitor. 3840x2160 @ 60 Hz definitely won't work on it.

I run CRU and 2560x1440@59.950Hz (241.5 MHz) appears in Detailed resolutions. I untick Include extension block, and reboot, but I still can't select anything about 1920x1080 from either the Win7 select resolution or the NVidia control panel (which is version 2.6.650.10)

I've not updated the Nvidia drivers since getting the laptop a couple of years ago - not sure if that would help?

HDMI is limited to 165 MHz pixel clock. You might be able to get around that by adding a custom resolution using the NVIDIA control panel. If not, either the refresh rate has to be reduced to 40 Hz, or the driver has to be patched: https://www.monitortests.com/forum/Threa...ck-Patcher

That won't work at all if the laptop has NVIDIA Optimus switchable graphics (NVIDIA/Intel GPU switching). HDMI was not meant for 2560x1440 @ 60 Hz.
