If the laptop is capable of 4 lanes but the panel only has 2 lanes, then it can only transmit 2 lanes.

Ok thank you, this makes perfect sense now

edit: Btw i am able to set the gpu in bios to discrete only, so that only the nvidia gpu is used. Would i be able to patch the pixel clock then and overdrive the 2 lanes available, or it won't work?

edit2: Well i've tested it, set discrete graphics only, adding the resolutions via CRU wouldn't appear, had to set them through custom resolutions in the nvidia control panel, and any resolution above 240mhz pixel clock will freeze the pc with black screen after hitting the test button. Worth noting a couple of point though:
-After successfully testing a custom resolution in the nvidia control panel will increase the pixel clock calculation. So for the same timings, while with CRU i can get to 103hz, with nvidia i can only get to 101/102hz. Weird.
-With the intel graphics any overclocked resolution will report 6-bit colour in the windows display settings, while with nvidia will report 8-bit colour in the windows display settings, but in the nvidia control panel will say 6-bit under the "use nvidia colour settings" but 32 bit in the custom resolutions menu..go figure..

Afterall i guess i should be happy with 60->105hz XD
