Your LVDS display is connected to integrated graphics and Clarksfield CPU don't have integrated graphics. This one will not works.

You need a Arrandale cpu.

If your notebook have a nvidia optimus card you can try to connect a external display to hdmi port but internal display will not work

doesn't work even if I put a modded bios with a chance to select which graphic card use?

Internal display it's HARDWARE WIRED to CPU

Hi,
I installed an i7 740qm processor on my Acer 5742g model laptop, but it did not turn on.
Only the fan is running and there is no screen. I unlocked the bios, but I don't know what setting I should do.

Try before installing new CPU to change BIOS option Display Mode to Discrete Graphics.

There is that option but it is not editable
currently the display mode is Discrete Graphics
