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.

Thanks for the reply. Yep, its got the switchable graphics. Does that mean I'm totally borked? I tried a 40Hz refresh and that's not helped...not tried the patch yet. The intel utility sees only the internal settings, won't let me select external monitor or add a higher resolution, so I'm guessing that its not involved when I've got the switch on "Speed"
