For BenQ/ZOWIE 144Hz 1080P Monitors
200Hz+ Overclock Successes So Far
- XL2720 at 220Hz
- XL2720Z at 220Hz
- XL2420G at 220Hz
- XL2430T at 215Hz using S-Switch trick
- XL2411Z at 200Hz via DVI
- XL2411Z at 210Hz via DVI using ToastyX Pixel Patcher (uncap DVI)
No S-Switch Needed!
Credit to forum member loopy750 for discovering the S-Switch 220Hz Overclock Hack for BenQ 144Hz monitors!
However, it's possible to overclock without the S-Switch! You heard about this on Blur Busters first.
And, yes, it lowers lag to less than 144Hz
Potentially Supported Models
Most 144Hz 1080p BenQ / ZOWIE monitors with DisplayPort between 2013-2019.
XL2420, XL2420Z, XL2420G (Classic Engine), XL2420P, XL2411P, XL2430T
IMPORTANT: Older T-Series Will NOT work (all models older then XL2430T)
-- You need 144Hz and 1080p and DisplayPort in your BenQ/Zowie
-- Easiest with NVIDIA GPU
-- This won't work with 240Hz BenQs
-- This won't work with 1440p BenQs
-- Works with DisplayPort (~220Hz) and DVI (~200Hz). Try both ports, one may overclock higher than other.
-- IMPORTANT: For old XL2720Z (V2) do NOT combine blur reduction with overclock unless you know what you're doing (strobe backlight voltage boost bug in pre-2015 firmwares). If you dare try, set Persistence / Strobe Duty to 5 or less BEFORE you overclock.. This risk doesn't apply if you are not using motion blur reduction.
The "Out Of Range" Defeat Trick
- You need two monitors to make this easy.
- Set your BenQ/Zowie as primary.
- Download Entech Taiwan SoftMCCS
- Launch SoftMCCS onto 2nd monitor (the one you're not overclocking)
- Launch NVIDIA Control Panel onto 2nd monitor
- Select the 220 Hz custom mode in NVIDIA Control Panel (create it if not already created)
- Your BenQ will immediately go OUT OF RANGE
- Now in SoftMCCS (displayed on your 2nd monitor), click "OSD language - 0xCC" -> Activate
- Next, click "Display application - 0xDC" -> Activate.
- Doing both of the above will dismiss the OUT OF RANGE watchdog and your 220Hz will appear!
- In SoftMCCS, select "Movie" radio button (nothing will happen until step 3)
- Click "Display application - 0xDC" -> Activate.
- 220Hz becomes visible but sharpness will go out of whack. Slide "Sharpness" to "5"
- The picture looks much better color quality, and graident looks fully 8bit (via GPU soft-DRC)
You will have to repeat the important "OSD language" -> "0xCC" -> "Activate" in SoftMCCS steps every time you switch back into 220Hz. To prevent having to do this too many times repeatedly, make sure you have SoftMCCS running on your 2nd monitor and make sure your Desktop is 220Hz before you launch your game in 220Hz. Then Windows/Game is not doing any mode switches. Do not Alt+Enter / Alt+Tab. The single most important step is SoftMCCS window open on 2nd monitor, and ready to click "OSD language - 0xCC" -> Activate .... whenever you see an OUT OF RANGE message pop up on your monitor.
Disclaimer: Blur Busters disclaims responsibility for any damages. Do at own risk. It works on my BenQ XL2720Z, but your mileage will vary.
