Interesting.. so It'll be 'out of range' at 144hz if i choose to use a large VT.. like i am at 165hz, requiring the workarounds for the 165-240hz overclock tweaks. Thankfully my XL2720Z did come with an S-Switch, and I have successfully used it to avoid black screens when changing resolutions & refresh rates. I also installed the OOR-Buster 1.4 and have it setup with a proper delay so that it is almost always able to defeat the 'out of range' alert when I switch to my 165-240hz 1080p resolutions.Falkentyne wrote: ↑08 Dec 2020, 15:19144hz uses a reduced vertical total (VT), which I think is 1094 or something. You can increase the VT via a custom resolution but it will go out of range. You can try using the "S-switch" bypass, or the software tool black screen workaround (for the 165hz-240hz overclock tweaks) in the display overclocking thread, to force the monitor to try to display an image anyway. I would try using the VT range of 1350-1358.

The things to look out for, if you can get an image is:
1) if the monitor locks up and won't display an image after you do the bypass (if that happens it just isn't capable of it).
2) if the image is corrupted and unusable.
3) if the image appears but has micro-stuttering or frameskipping. You also need to see if it sometimes is smooth and sometimes frameskips, after a resolution change/reset.
If you are dealing with #3, try changing the vertical total up or down by 1. You can also try changing the horizontal total up or down 1 also. A small change in the pixel clock can get the monitor to work.
Thank you for the tip, why exactly is 1350-1358 a viable VT so often, and for so many refresh rates at 1080p on these BenQ's?, I noticed those VT's mentioned before.. is it just because those are VTs that are within the monitor's rated KHz, or because they produce the best effect of "reducing crosstalk"?
and what exactly causes a resolution to go "out of range" in these BenQ's is it the MHz of the custom resolution, or the KHz? and what's the limit to stay under to avoid "Out of Range"?
Thank you Chief, for he tutorial, I've skimmed through that 144hz BenQ OC thread.. I'll have to go through it again to see if there's anything I missed.. but that tutorial in your post above is REALLY helpful! Since my max stable OC that i tried and achieved was 240Hz at 1080p, my KHz were 262.560 (pixel clock of 520.92) .. so i've got a scan rate limit of 262560?.. so this means at 144hz i should be able to do 262560/144 = 1823.3 VT at 144hz? is that right??Chief Blur Buster wrote: ↑08 Dec 2020, 22:11Overclocked Vertical Total FAQ
You can use the 220 Hz overclock trick to get 144Hz+Large Vertical Total.
For more information about overclocking 144Hz 1080p BenQ ZOWIE monitors, see The Overclocking Thread For 144Hz 1080p BenQ ZOWIE Monitors.
This is much harder than a plain large vertical total, so this is for more advanced users.
So i jut have to ensure the OC doesnt break AMA overdrive.. and that i should check if AMA Premium looks better for 144hz with a VT?
Oh and a odd question i have: WHY is it that we can set almost EVERYTHING to the shortcut menu on the XL2720Z.. like "Contrast" "Input" and even "Black Equalizer" etc.. but WHY can't we have a shortcut for AMA? it's the MAIN setting i always have to dig into the menus for.. to enable the AMA Low tweak.. I wish it was just one click away lol
Also Chief, about the "1920x1079 Trick + OORBuster".. you can avoid this if you have NVIDIA. in the control panel there is a setting called "Preferred Refresh Rate" under 3D Settings.. - if put on "Highest Available" it will ALWAYS switch to the highest OCed refresh rate listed in the Control Panel (as long as you have the proper CRU resolution detected by NvCpl), this way i dont have to use a custom resolution to force my OCed refresh rate!.. Of course, the downside to this.. is that it really only works if you ALWAYS want to force your max OC refresh rate... if you have games where you want to use 60hz due to a 60fps in-engine FPS lock (for single strobe), then you have to change that setting back to "Application Controlled" and maybe use the 1920x1079 trick..
A question about the 1920x1079 trick btw: doesn't doing this cause the resolution to be scaled improperly on the monitor?
