BenQ UNIVERSAL 144Hz->220Hz OVERCLOCK for 1080p 144 Hz

[arebx]

hi, i wanted to overclock my XL2411Z but for some reason every custom resolution or hz that i set in CRU doesn't appear in windows settings and if I try to overclock my monitor from the AMD software it says that custom resolution aren't compatible with my screen. What can I do?

[Rayback]

Hello.

I tried to overclock my screen. Benq xl2411. He is not listed in the first post.

I have dvid hdmi and vga on the screen.

I just tried with dvid.

Uncap blackscreen. Work with 2 step. One for black screen. One for hud error" out of range"

205 hertz black screen
200 hertz give me flick white pixel in somes zone.
195 hertz. Same but not really visible.
190 hertz. Seems to be ok. With test ufo.

With blur reduction. I can t pass 170 hertz with really dark sceeen.

Thank you for the tips!

Can i optimise something?

How difficult would it be to make OorBuster work on Linux? I've been using Manjaro for about three years now and I have been missing getting 165Hz out of my monitor as I used to on Windows.

If you already know DDC commands you can create a script instead using the Linux DDC command utility based on the findings of the first ten pages of this thread about the magic DDC commands to dismiss the “Out Of Range” popup.

I'm not familiar with DDC commands, but I'll do some research and hopefully get a script working. Thanks Chief

Update:
So I have managed to get a script working to dismiss the "Out of Range" message. I am now however facing an issue where I am getting severe artifacting as can be seen in the video below.

Does anyone have some advice for me to solve the artifacting?

hi, i wanted to overclock my XL2411Z but for some reason every custom resolution or hz that i set in CRU doesn't appear in windows settings and if I try to overclock my monitor from the AMD software it says that custom resolution aren't compatible with my screen. What can I do?

I am having the same issue did you find a fix?

[Chief Blur Buster]

You could convert the ToastyX numbers earlier in this thread, to proper ModeLines.

There's a formula to convert a ToastyX GUI into one text line (called a "ModeLine")

Did you try this, and did it work?

Also, this is too low:
HorizSync 30.0 - 200.0

Remember HorizSync is number of pixel rows per second, as screen refresh top to bottom -- www.blurbusters.com/scanout !!! -- Assuming a typical 1080p refresh cycle is 1125 pixels tall (HDTV standard size; 1080 visible plus 45 VBI (vertical blanking interval) being used as spacer between refresh cycles). Now if you're needing overclock headroom to 240....

1125 pixel rows x 240 refresh cycles per second
1125 x 240 = 270000
Scan rate = 270000 pixel rows per second = 270.0 KHz

In this case, one pixel row is transmitted out of the GPU output in 1/270000sec, during a VT1125 240Hz signal, spewing out all those pixel rows, as a defacto serialization of 2D image into a 1D cable.

So whomever told you to use 200.00 totally screwed up, and since I know one person overclocked to 265 Hz successfully, so let's round up to 300.00 KHz or 350.00 KHz to give you enough optional overclock room. Remember, these are not guaranteed to work, but you don't want to limit your own horizontal scan rate.

Corrected numbers:
HorizSync 30.0 - 300.0

As a rule of thumb, multiply your vertical resolution by approximately 1.05 (common VBI size is ~5% of vertical resolution, this varies a lot), then by refresh rate, then divide by 1000, add a safety margin, and that's the upper-bound number you should use for HorizSync So napkin math (1080p x 1.05 x 265 Hz) is about 300000. This is a mostly futureproof formula, for any future vertical resolution that's not a big VBI (e.g. Large Vertical Total, Quick Frame Transport, etc). Large vertical totals can reduce strobe crosstalk if you use motion blur reduction, but this is not as important if you're not using strobing.

On the GPU, refresh cycles are into a stream of pixels when pushed out of (VGA|DVI|DP|HDMI|tincans|whatever), raster-style (like reading a book or calender), beginning with the upper-left pixel, left-to-right, top-to-bottom, serializing 2D into 1D. The blanking intervals are the (porches + sync) combined. And you've got both a horizontal blanking interval and a vertical blanking interval.

Figuratively, by only using "200.0", somebody is trying to fly an airplane without learning to fly an airplane first. If you can create bash scripts and compile a Linux kernel, then this stuff is dirt-easy to learn. This might not be enough, you may need to learn how to convert ToastyX numbers to Linux ModeLine numbers.
Please study Custom Resolution Utility Glossary

A video signal is mapped out like this, this will help you understand how to convert ToastyX numbers to ModeLines:


P.S. Most Linux users have tended to be advanced users/programmers. I welcome such readers to read do some advanced reading of refresh cycle science & physics, www.blurbusters.com/area51 -- not relevant to the above, but these are textbook reads by less experienced engineers at monitor manufacturers. Some people do buy 240 Hz and 360 Hz monitors just for better web browser scrolling and improved desktop experience (240Hz has 1/4th the scrolling motion blur of 60Hz, and 360Hz has 1/6th the scrolling motion blur of 60Hz), as high Hz is not just for esports anymore.

This is outdated or really a not properly written tutorial, if its even meant to be one.
There is no "movie" radio button in softMCCS btw.

Deets please. What model?

The SoftMCCS settings appear/disappear for different BenQ monitors, apparently. SoftMCCS reads what settings are available in the monitor, and makes settings appear/disappear in SoftMCCS depending on what the monitor supports.

This is an unofficial guide in a forum, actually.

There are too many things going on at Blur Busters to create an official main-website guide on this item at the moment -- since I don't have access to all models of BenQ monitors. You, users, need to help with this Forum thread -- if a specific model of a BenQ monitor doesn't have a Movie setting, please collaborate in this discussion forum thread .... So everyone can improve this unofficial guide (and maybe eventually be rewritten to an official guide). Thank you!

I have the xl2430t model. There is a problem when it passes 165 hz. It does not work above 165 hz. Is it because gtx 550ti old video card?
connected with dvi
The bidet says out of range when I turn it on and off on every monitor, the screen comes up when you press the control button of the monitor, how can I fix it
thanks in advance
