    You could try uninstalling the native driver that the screen itself loads and load the old driver manually but you might lose out on the higher refresh function then if you are talking 120Hz panel as the upgrade being put in place of the stock panel... Maybe it is possible to merge two drivers into a single custom driver? This is definitely something I am interested in learning how to do but for now it is way above my head, lol.

    A 120Hz TN panel shouldn't be too hard to come by as @polihedron has shown. The IPS panels may be a bit harder to source... Depending on your gamut preferences. I would say there is a good chance that the panels that work in the 7567 will have a decent chance at working in our 7577 machines.

    I hear the TN panels are almost as good as IPS anyway so I don't see the need to go through the effort.

    How about this ebay link that sell Lenovo brand of 15.6" AHVA ips screen?

    https://www.ebay.com/itm/NEW-15-6-L...A-IPS-PLS-IBM-LENOVO-5D10G16541-/400991261360

    Will this match your theory if someone want to use this to replace inspiron 7577 regular ips screen to AHVA ips screen?

    Based on my personal theory and this practical example of trial and error:

    https://www.reddit.com/r/Monitors/comments/6ncfaz/is_there_a_standard_for_edp_connectors_on_screens/

    It would appear as though it's a pretty good chance it would work. Don't be pissed off w/me though just in case it doesn't lol.

    Also note: sometimes manufacturers use 40 pin cables without all of the pins populated. Cracking open your unit to count the number of pins on the mobo connection might help clarify some things as well.

    For example, even if you have a 30pin connector on your lcd screen end, you might have the 40 pin connector where it attaches to your mobo but with only 30 of the 40 pins populated. This keeps things simpler for the manufacturer in some cases and eliminates the need for different mobo part numbers and configurations and/or adapters on the mobo end.

    OTHER THINGS TO CONSIDER:

    How different is the power draw requirements from stock?

    How thick is the physical dimensions compared to stock screen thickness?

    How many mounting tabs does the screen have (if any) and are they in the same location as the stock screen mount bracket?

    Are in-house panel brands actually renamed/rebadged mainstream-producer panels? (That would be the better case.) Or are they actually being made by the same OEM that's producing the laptops the screens are meant to go into. (This could prove problematic in terms of compatibility and non-standard pinouts.) I mention this because the brand panel you linked to says Lenovo. I'm not exactly sure how many unique lcd screen manufacturers exist in the industry... I know LG, Phillips, Samsung, AUO are all commonly known manufacturers.

    Driver issues.

    Mobo and/or other hardware conflicts.

    [The bottom of this page has a nice little summary of various panel types and manufacturers.] https://www.pchardwarehelp.com/guides/s-ips-lcd-list.php

    I WOULD ALSO:

    Try emailing the UK eBay seller you linked to and ask them straight up about some of this stuff. Tell them what you are after and see if they have a specific recommendation for you. Make it clear you don't just want a stock replacement but a custom upgrade. You could even direct them to this thread and encourage them to make an account and post some info answering everybody's questions and reservations so it could be helpful to everyone who wants to go this route in the future and be forever searchable. This is a hot topic on the Dell Inspiron 15" laptops. Not to mention it might potentially drive them some business.

    These are the things I think about. My $0.02

    Okay so since we are on the topic of displays would anyone mins explaining to me what we'd be losing out on if we take a screen without gsync. Would it even be possible to find a 120hz IPS/high quality TN display that's gsync?

    SEE HERE:

    https://www.laptopscreen.com/blog/do-you-need-a-g-sync-screen-replacement/

    http://www.tomshardware.com/forum/id-3590217/upgrading-laptop-display-sync.html

    It sure sounds like a bunch of marketing wank to me... Maybe try googling and crosses referencing some more sources and/or forums to confirm the first link as well. You can try MyDigitalLife as well as the HardForum sites, they may know more details and specifics into the nuts and bolts of it all.

    READ THE LAST TWO PARAGRAPHS HERE:

    http://www.tomshardware.com/news/vesa-displayport-freesync-amd,28524.html

    It sounds like it's mostly a driver limitation more than anything according to that post.

    SOME NBR SEARCHES DATED 2015-01-01 AND NEWER:

    Posts #2 and #4:

    http://forum.notebookreview.com/threads/mobile-g-sync.776763/

    Gsync requirements ala NBR thread:

    http://forum.notebookreview.com/threads/g-sync-requirement.808948/

    This NBR thread brings us full circle back to custom BIOS flashing:
    http://forum.notebookreview.com/threads/g-sync-query.809526/

    FINAL THOUGHTS:
    Yes, it could technically be possible with a lot of deep knowledge in multiple areas of low level computing but on a mid-level machine like ours it wouldn't seem very worth the time, hassle, and risk. Unless you're into that sort of thing.

    It ultimately boils down to paying whatever premium the OEM and hardware manufacturers demand for the extra few lines of code in the driver and BIOS in addition to whatever it costs them to license the adaptive sync moniker from either AMD (FreeSync) or NVIDIA (Gsync). DRM bull_shit at its finest holding back better user experience and/or performance on the same exact hardware basically. All in the name of more profits for already insanely profitable companies... Murika!

    MyDigitalLife forums have tons of great BIOS modding resources if you spend the time to learn the trade.

    Try a request thread at www.bios-mods.com for custom bios instead of doing your own.
    There are experts and modding your own bios have chances of bricking if something goes wrong.
    Try there, guys there are best at custom bios.
