I'll do a 60 hz test for you real quick and edit this post once it's done. Here you go, terrible as predicted
Yep, thought so. Sadly.
Black frame insertion probably looks good, creating 60Hz single-strobe -- see second UFO at

VT1350? How quaint; that's XL2411 specific.
Try VT
5500 for Quick Frame Transport 60Hz on 240Hz BenQs. The electronics might not support it, but it hopefully should (as long as Horizontal Scan Rate and Pixel Clock is identical to original 240Hz timings).
Mathematically, quarter-refresh-rate is capable of quadruple-vertical-total, on some panels.
So if 240Hz was VT1125, just double it for half Hz (120Hz) and quadruple it for quarter Hz (60Hz).
Combined with RTSS Scanline Sync with end-of-VBI frame presentation, you can reduce the input lag of 60Hz VSYNC ON by 3/4ths of a refresh cycle (12ms less latency).

Sorry Chief. i didn't mean to cause trouble. I Just want to make sure before I buy a very expensive monitor. I'm a disabled person living on SSI and section 8 so I'm trying to be careful with my money. I'm sorry.
Oh no, you didn't cause trouble -- just wanted to warn you in advance that all 60 Hz double-strobe is all equally bad.
I'm just about to give into buying it soon because the 240hz strobing and RTA artifacts are extremely good and the 100 and 120hz are acceptable and it seems that the monitor responds to the old VT tweaks that reduce crosstalk also. Just haven't made up my mind because I need an oscilloscope also...

No amount of tweaking can fix that mess.
Thank you!
Actually your video was FAR more helpful than I even anticipated.
The inverse (or lack of it) ghosting (Overdrive artifacts) on your 60hz are MUCH MUCH better than on my XL2720Z at 60hz when I enable double strobing (I just checked)
Mine just has a purple corona behind the double images, and if I toggle AMA to reduce the overdrive, then I get positive ghosting.
Yours barely has any at all!
This would be the best monitor Benq ever made--ever--if they just allowed single strobe (or if I could hack it in by using a strange horizontal total).

I tried very high VT with 60 Hz but unfortunately it wouldn't work despite it having a low pixel clock. I don't know why this is the case as higher refresh rates let me push the VT much higher.

Was Horizontal Refresh Rate
and Pixel Clock, exactly identical to default 240 Hz?
Usually, the best way to do maximum-compatibility large-VT experimentation is to lock those numbers while increasing Vertical Total
to decrease the refresh rate until the target refresh rate ...
Basically all CRU numbers are unchanged (Relative to 240Hz) except for Vertical Total and Vertical Refresh Rate. (They interact, so change only Vertical Total, keep increasing until the target refresh rate is reached).
That said, perhaps 60 Hz operation is a special-case within the monitor -- that would be weird.

Yup they were locked and the only thing I altered was the vertical total.

If i’m looking for a monitor for pure gaming. Would the Zowie S series be better than a VG279QM?
I just got the VG279QM yesterday, and to be honest, it’s pretty damn good and responsive. It replaced a PG258Q, and it’s both faster and the colors are much better!
But, i tried the ELMB, and my aim/shots were a lot better than ELMB off. But i cant play with a brightness that low.
My question is, would the DYAC+ be the right choice? I really dont care too much about colors, i just want the most responsive monitor for pure gaming. That’s it!

My 2546s will be arriving tomorrow, and my first "premium" monitor, so I want to get the best out of it.
I will have access to a x-rite i5 pro colorimeter towards the start of next week, is there any stats I can get that might help people, I am a total novice, but if you point me the in the right direction I could possibly help.

I have an order on both amazon UK and FR, only the UK seems to have received their inventories... Which is fine because the price was crazily good (379 pounds)

Me, Chief and Masterotaku found something like this on XL2411Z's and XL2720z's at 60hz. VT would only go up to 1350. VT 1500 was "Out of range" at 60hz. Yet for some really weird reason, 61hz worked at VT 1500. 76hz also didn't like anything. Go figure that one out
(Chief do you remember this stuff? I know it was some time ago....)
However a VERY high HT worked at 60hz. I think Masterotaku did HT 2816, VT 1350 at 60hz (to be honest, this was to work around an issue regarding patched dvi single link rates crossing into dual link rates, and was not necessary on displayport, but the first XL2411Z did not have DP).
I wonder if some weird setting of VT 1350 + a very high HT, (or even VT 1500 at 61hz) can trick the monitor into single strobing at 60hz...
I'd order this right now on the spot if it did....
