    I cant go past 150hz effectively with my 30-pin EDP panel, but I would be curious if anyone with a 144hz 40pin edp panel has been able to hit like say 165 or higher effectively, given that you have 10 more connections.

    Can you break your panel? I have never seen any evidence to suggest that, as it either does or doesnt register the frequency. This is so far the most I have heard done: https://www.blurbusters.com/successful-60hz-180hz-overclock-of-stock-laptop-lcd/

    on a side note, I asked on there if there was an easy way to mess with firmware and have better response times, and the owner says thats doable, but would require alot of work on his part, and he usually only does that for companies with custom equipment.

    My LVDS panel on most of my laptops would hit 90hz+ topping around 110hz.

    My eDP 40pin wouldn't overclock at all. Might be different on my next panel the n173hhe-g32 but who knows.

    My best overclock is a 1920x1200 CCFL at 185Hz:

    Think it did so well because it was the first FHD(+) panel in a laptop and therefor might've been over-designed to be on the safe side. Also quite expensive at the time, so a bit more effort spent on the product probably didn't really matter as much.
    If you'd want to edit the edid only then you could stick with CRU (or flash it with software on older systems).

    But this is only the bit in the firmware that stores the display's parameters. Have read out the complete firmware from a few lcds and there were always two copies of the edid, so perhaps you might change both of them with a hardware programmer. But that didn't help much with my IPS though; 65 was still the maximum it could do. For overclocking a TN works much, much better.
    Yes, people have killed panels by overclocking. Just use small steps and make sure to drop some 5 or 10 Hz below the artifact level.

    I cant find where you edit in cru to somehow lower the response time. Currently my panel is 16.6ms, which is fine for 60hz, but to high for 150hz. How would I flash firmware on it??

    My panel pretty much refuses to be OCed. As soon as I attempt a change, it goes blank and stays black until 15 seconds are up. Also after I tried to OC, my display is now unknown in HWINFO and I cannot see my OC profiles anymore
