    Now that more people starting to notice, I bring up again this issue.

    Some people migt still be thinking buying a Pascal laptop, so here is a list to help decide.

    Here is a list of laptops and panels which I personally checked and confirmed:

    Affected by the issue:

    Clevo P775DM3-G - LGLP173WF4-SPF1 75 hz Only G-Sync+dx12
    Acer Predator G5-793 - LP173WF4-SPF1 75 hz Only G-Sync+dx12
    Asus GL702VS - AUO B173HAN01.1 (AUO119D) 120 hz Only G-Sync+dx12
    Asus G701VIK - AUO B173HAN01.1 (AUO119D) 120 hz Only G-Sync+dx12
    Asus GL702VI - AUO B173HAN01.1 (AUO119D) 120 hz Only G-Sync+dx12
    Asus GL703GS - AUO B173HAN03.2 (AUO329D) 144 hz Every situation

    Laptops that are NOT affected:
    Asus G703VI - AUO B173HAN03.0 (AUO309D) 144 hz
    Asus G752VM - LG LP173WF4-SPF3 75 hz
    Acer Predator Helios 500 - AUO B173HAN03 144 hz
    MSI GT73VR - Chi Mei N173HHE-G32 (CMN1747) 120 hz
    MSI GT75VR - Chi Mei N173HHE-G32 (CMN1747) 120 hz
    Clevo P775TM-G - AUO B173HAN03 144 hz

    Changing hardware (screen/vga) did not fix it. Maybe other laptops are affected however I only tested these. The GL703GS was the worst.

    For laptops with B173HAN01.1 the solution to fix the issue is use driver 376.06! This 1 driver can fix it. Available on the Asus website. May need inf modding for some laptops to allow install.
    For other panels I did not find a fix yet.

    More on the issue with examples:

    I really hope the new RTX laptops will mot be affected..

    Confirmed on ASUS GL703GS with AUO B173HAN03.2.
    Should we ask ASUS a free repair fix for re-tuning overdrive? Or maybe a replacement with B173HAN04?

    This is interesting (inverse ghosting issue with previous GL703GS): new Armoury for GL704 includes a mod-switch to conrol Overdrive!

    Is it a response time issue? Could an aggressive custom resolution with specific timings help?

    That is a very good question.
    Would be nice to compare the timings between 2 panels 1 which have this issue and the other which does not...expesially if both are the same panel just different laptop brand.

    I also wonder why does the problem only appear when dx12 is enabled on some panels...does dx12 API somehow affect GSync+panel timings ?

    I asked the same to CRU's author and he said can't help in our case… Requires an overdrive fine-tuning, or it's a Nvidia driver issue for someone .
