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).

I did that test and didn't notice any frameskipping, it's all smooth. I don't really know how to explain this, at VT 1502 and with blur reduction ON, the image looks so clear that you can actually see the individual pixels and the lines they are in, i play CS:GO and it's easy to notice when you look at a smoke grenade or looking at a piece of skin in movies, i think it's related to the pixel clock, because when it goes down it seems to disappear, but the brightness also goes down so i'm not really sure. *thinking about it, it looks like when you go near the tv and see all the pixels crammed in there* I sit at 3 to 4 inches from the screen and it's clearly visible when watching movies or playing CS. More ↑↑↑ HT, Less ↓↓↓ effect. My settings on the monitor:

Blur reduction(ON) - Strobe Duty: 15 (Max is 25/ 0~25)
Strobe Phase: 0 (I can reach 49 before the monitor blacks out)
Black eQualizer: 0
Color Vibrance: 9
Low Blue Light: 0
Instant Mode: On
Auto game mode: Off
-----------------------------
Picture Mode: Standard
Brightness: 100
Contrast: 52
Sharpness: 5
Gamma: 5
Color temp: R:98 / G:100 / B:99
AMA: High

Like i said, using 2080 i notice it very easily and the more i go up in the HT the less i can see. If you know anything about it, let me know! Thanks for all the help!

Hi,
You sort of contradicted yourself in your last post. First you said "the higher the pixel clock, the more "pixels" you can see on the screen (is this true?).

Then you said "More HT, less effect". I don't understand what this means. This sounds like you just said the exact opposite of what I wrote in the above sentence.

When you use the VT tweak, look on windows at a GREY background. Aida64 has a grey background image on its monitor test but the free version has an annoying watermark. You can try using the GREEN test on Eizomonitor test.....

When you increase the HT do you notice a scanlines type effect on the all green background in the eizo test? Is this what you are describing?

Are you saying you LIKE having a high HT over a 2080 HT, with a VT 1502??

I never noticed any sort of...um....."seeing pixels clearer" like you said. I only know that if the pixel clock gets too high, you get image corruption (shimmering/flickering pixels).

is *THIS* the effect you are seeing?


(this is 125hz, VT 1497, pixel clock 389.22 (displayport).
you can see a scanlines effect. Notice every few horizontal rows, a line of pixels is brighter than the ones around it?)

Here is 120hz (120.5hz actually, default VT (1144)).
Notice everything looks more even and any scanlines effect of alternating lighter pixel rows is almost completely gone?
