You are using the wrong timings.
You are using the 60hz timings for 100-130hz; this must not be done.
These timings may or will cause image corruption because the scaler is being pushed too hard when you are using VT tweaks. Its fine without VT tweak but you can check "LCD standard" first to see your porch, sync and HT are too high.

For 100hz and higher, change 88/4 to 48/3 for front porch.
Change 44/5 to 32/5 for sync width
change horizontal total to 2080.
Vertical total is fine if you want to use VT tweak.

LCD reduced is for refresh rates higher than 129hz if you get black screen out of range error, you must use VT 1098 from 130 hz - 145 hz. You can not use "VT tweak" at 130hz+. Firmware will not allow it.

Toastyx can explain why 100hz/120hz don't use 88,4 and 44,5 and 2200 HT. If you check in CRU with "LCD standard" and enter 60hz you will see the timings. If you change 60hz to 100hz, you will see porch, sync and HT values change to lower.

This will also lower the pixel clock too. 125hz with VT 1500 should be around 396 MHz pixel clock with (48,3) front porch, and (32,5) sync width and (2080) HT.

Don't worry about polarity and don't change kHz manually. this is set by combination of other values.

Yeah, i didn't notice that my timings were according to the LCD Native preset. About the HT, does 2160 give me any benefit over 2080? Like a little reduction in blur, or something like the VT tweak? Changed the timings and it looks almost fine. Using 2080 HT i can see horizontal lines on the screen, if i up it to 2160 it goes away, that's why i set it that way, even with the correct timings they appear... Any problem to keep it at 2160? I only notice artifacts at 2175+ so i bumped down to 2160 for safety, but i don't actually know if it's safe or not, thanks for the help!

Increasing the HT has NO benefit whatsoever except putting extra pressure on the scaler. I'm not sure if it will affect certain Vertical totals causing frameskipping or not; if you want I can test that for you. Usually if a certain vertical total causes frameskipping (you can see it EASILY with blur reduction on, in Test UFO->Alien invasion....if you see the image "jump" repeatedly or every several seconds its frameskipping), then try another VT in the range of 1497-1502.

I'm not sure if HT affects that or not. However raising the HT does raise the pixel clock so its not certain what's causing what. NO effect on blur reduction.
Usually there's no 'danger' as far as I know....if it has artifacts then its too high. But usually you should keep the HT at default, and lower it if you want a lower pixel clock.

The only thing that makes the "overdrive" better is by turning on blur reduction first and then setting "AMA" to high AFTER enabling blur reduction. On XL2411Z and XL2420Z (and MAYBE XL2430T, u can test for urself ok?), it lowers the overdrive inverse ghosting by about 10%. On XL2720Z, it lowers it by a drastic 50% (much better), but you have to drop the contrast lower to avoid too much normal ghosting.

*edit* ok changing HT does NOT affect frameskipping is a certain VT frameskips (e.g. VT 1502 at 85hz refresh rate, VT 1501 is perfect on XL2720Z).
