    Hello, I have this old Asus Laptop, it's based on X55CR motherboard, the cpu is an i3 and is directly soldered to the MB, the GPU is Intel HD3000.
    The LCD panel is https://www.panelook.com/LTN156AT24-P01_Samsung_15.6_LCM_overview_15236.html
    I modded my bios to remove MSR lock (for MacOS) and unhide "chipset" menu.
    From within chipset menu I can access some LCD control submenus as follow in pictures.
    As far as I know the LVDS cable should be single channel at the moment. The screen is 40 pin.

    Somebody on a post on this forum mentioned the lanes on the motherboard, I don't know how to check how many are there, maybe someone can tel from the pics I posted.
    Question is, does anyone know what do I need to replace the screen with a FHD one?
    And is it even possible?
    Maybe with this cable https://www.waresphere.com/store/for-asus-n53-n53jg-n53sn-n53df-lcd-lvds-cable-14g22101620v-fhd.html
    and this screen https://www.laptopscreen.com/English/model/ASUS/N53S SERIES/?set_currency=EUR
    ?

    Here is a comparison between the original panel and the one on n53s which is samsung too.
    They seem pretty identical to me. Does anyone have an idea? Could this work?

    Anything is possible if you set your mind to it.

    They appear to be the same size and pins so it should be a simple swap. I was figuring they wouldn't be readily available but, it seems they are in the typical $80 range.

    There are many compatible models for the 1920x1080 listed under the https://www.panelook.com/modeldetail.php?id=15615 .. I found they are more or less 58 euros from UK. Anyway the problem here is understanding 1) is the the original LVDS cable 1 or 2 channels? 2) Can I swap it with the n53s series LVDS cable which is 2 channels? 3) Does the MB have sufficient lanes anyway?

    Google the CPU and look at the specs for displays. It will give you an idea on the resolutions and capabilities. W/O that info it's hard to tell you the answer to any of the questions regarding channels / etc. MOBO doesn't really dictate the lanes available it's based on the CPU/GPU though sometimes cheaper models don't provide the solder points to allow a higher capacity to be used.

    Since this is a 10 year old laptop.... it's a 60 euro experiment vs buying a new laptop. If you need to swap the LVDS cable it's another $20 typically.

    HD3000 is capable of FHD.
    The CPU is https://ark.intel.com/content/www/i...ore-i3-2370m-processor-3m-cache-2-40-ghz.html
    it lists gfx output as eDP/DP/HDMI/SDVO/CRT .. however the PC now uses LVDS so I don't really know what that information is good for.

    @Chriz74 if the laptop was available in configurations with FHD screens, FHD screen will work. Otherwise, tou need to find and study the motherboard schematics to determine the number of lanes, and LVDS cable pinout if there are indeed 2.

    Can’t it be checked some way in linux via software?

    With it's LVDS cable it doesn't turn on. With the laptop one it turns on but image is not crisp.
