    Hey folks, have a Clevo P370EM that I just got working....(after EDID corruption fix, that was fun), and was wondering what all is needed to go to the 120hz display up and going. Currently have the 60Hz one - which I think is the matte LVDS one.

    If the motherboard has the eDP connection point, is it just a cable and 120Hz screen at that point? BIOS modifications from stock necessary? Would I have to solder or get a new mobo if it doesn't have the 30(?) pin eDP connection point?

    I think the discussions I had here might be helpful: http://forum.notebookreview.com/threads/laptop-screen-upgrades.816139/page-46
    If you have the eDP port, then you will need a new eDP cable, the part number is in the manual of your laptop.
    I couldn't find any 30 pin displays with 120Hz. I bought an eDP adapter from 30 pins to 40 pins and I hope to fit in a 2K , 120Hz display.
    However, the 30 pin connection is only 2 lanes DP 1.2, meaning my max is 2K @ 85Hz. We shall see.

    Hey Blacky!

    That adds to the slew of threads I've read at this point, haha. I took a gamble on this:
    http://forum.notebookreview.com/thr...e-for-clevo-p375sma-eurocom-x7e.797823/page-2
    @t456

    And ordered the parts lp173wf2-tpb1 and 6-43-P37E1-020-J. Next is exploring a 1070 in the machine....I saw BennyG tinkered with 1070s but there doesn't seem to be a whole lot on it even though Eurcom's site mentions 1070s working in the P370EM.

    Not enough bandwidth in single channel eDP for 120Hz.

    The P370EM3 used a 120 Hz eDP display. You can get that and the funky 30 to 50 pin eDP cable that came with it.

    There is another laptop that came with a 30 to 40 pin eDP cable. This is electrically incompatible with the P370EM, but it can be rewired to be compatible by pulling out and rearranging the contacts in the motherboard connector. This cable lets you use 40 pin 0.5mm eDP screens, which there are a lot of including many 4K screens.

    For both scenarios you should flash over to a P370EM3 bios.

    Just wanted to let you all know, the parts listed above finally came in. I was basically able to plug and play given my motherboard had an EDP port already soldered on. Lucky me!
    Also got a cheap 980m to go with it which was also plug and play. Pretty happy!

    No BIOS were modified, either MB or vBIOS.

    Good to hear. You are still running a P370EM BIOS? How well is brightness control working?

    Yeah, stock BIOS that was on it since I got it in like 2012 or so. No brightness control it seems. Changing does nothing even though you can see the Windows slider move.
    Almost want to try to see if I can get a 1070 mobile working in it now....

    A non-clevo 1070 will work fine as long as it physically fits and you do a driver .inf mod. MSI cards are the best, but are slightly oversized.

    Flashing to a P370EM3 BIOS should make brightness control work. Flashing downloads that you hope are what they say is always a brick risk though.

    The EM uses brightness control from the EC chip, while the EM3 uses brightness control from the GPU. Idk why Clevo made LVDS and eDP BIOS different in that regard. On the eDP cable the EC brightness and GPU brightness are on separate pins. The eDP cable is connected to the GPU eDP signal, which is disabled on the EM bios.

    The MSI cards do have some nice power circuitry on them.

    So a non-Clevo1070, any reason it has to be that way? Or will it just be an easier process overall if one goes non-Clevo? I will see if I can find something about the .inf mods.

    Guess I can always email Eurocom to see if they'd provide me with the BIOS as a first try.

    Clevo 1070s are much larger than normal and flat out don't fit. They also need a few additional wires soldered to the MXM slot to make work even if you do cut up your laptop to fit it.

    Standard cards stay the same width as the connector, that's the ideal shape for your machine.
