Umm ya, to me it just looks like non-strobing backlight mode versus strobing backlight mode. Not sure what is special about "DyAc"?

Only thing I can think of is maybe they put brighter LED's for the backlight so the screen can be brighter and/or make shorter pulses to make the motion clarity better...

I wonder if they simply made the monitor function like the XL2720Z did without VT tweaks?
But Crosstalk tests would really help too.

Luckbad said that it was strobing "in sync" at 91hz, 85hz and 75hz, but it didn't look smooth like 100hz did. But it wasn't stuttering.
This sounds like it is double strobing.

I'm still waiting for 60hz tests (single strobe=flicker city so it's obvious if it works), but on the older Pre-XL2730Z monitors, if "Single Strobe" is disabled, it will double strobe at every refresh rate lower than 97hz, that the scalar identifies correctly (60hz and 85hz are identified at native res, 75hz is identified at low resolution), and will "single strobe" at messed up fixed settings at refresh rates that are unidentifiable (like 91hz or 80hz), using a bizarre preset of Strobe duty 020 and Strobe phase 040, and would ignore changing the settings, until Single Strobe were turned on.

The XL2730Z, however, would still try to strobe with 120hz timings, causing everything except "60hz double strobe" to be completely out of sync.

I wonder if 50hz would double strobe also? Single strobe data is missing from the previous monitors, causing overcurrent protection to kick in if "single strobe" were enabled at 50hz.

Oh ya has Luckbad disappeared? I'd love to know how bright this monitor is while strobing.

Send him a PM if you can or post a followup in his monitor recommendation thread on General. He's extremely busy (he works for Blizzard).

He did tell me that this monitor is double strobing at 60hz, and at 85hz it seems to do a partial double strobe (long+short pulse I'm guessing) from the way he described it. I know what effect he's talking about. I can make the XL2720Z do this by tricking the monitor to make 100hz refresh rate show up as 144hz (changing the VT to 1098). Then again it could be double strobing at 85hz also (I'd have to see the length of the first UFO image).

Seems like Benq made the strobe capability act more like the original Z series, but didn't include "Single Strobe" override.
If Chief Blur Buster can't make them add Single Strobe back, I won't be buying this. 60 hz double strobe looks as bad as no blur reduction at all.

I'm not too terribly worried about sub 100 Hz strobing as the flicker would be too annoying for me anyway. I have this on order from ShopBLT. Really only interested in the 144 Hz and 120 Hz strobing modes. Most interested in how bright it can get whilst strobing, as ULMB mode is usually far too dim unless at night.

Hope you get a good one!
Are you willing to try Vertical Total tweaks to see if they affect the strobe crosstalk in any way? (the XL2730 did not respond to VT, up to VT 1849, no effect). VT range should go from 1449 to 1849 at 2560x1440.

Im asking because it "seems" like they reverted the strobe code similar back to how the XL2720Z handled it. The XL2730Z would strobe at 8.3ms pulses (120 hz timings) even at 100hz and 85hz and lower, causing sync stuttering. The XL2735 strobes correctly at 85hz "in sync" but seems to either double strobe or do a long+short strobe. This is how the XL2720Z handles it, unless you override it with single strobe switch. So I wonder if Vertical Total increasing will affect the crosstalk again.

Yes of course. I am really interested to see what BenQ did with this monitor.

Probably won't have it for a month though, that's what the BenQ store said expect it for NA.

No online shops I could find in Europe that have them in stock ship to the US.

as it says REALTEK support in the description.
I just wanted to confirm that the RT809F-programmer can read the firmware, of the BenQ XL2730Z at least - I don't have the XL2735. However, I did not manage to erase or write anything. Although the programmer seems to do the erase or write just fine, it fails when running the blank check (after erase) or the verify (after write). :(
Of course, given the sparse information on how to use the tool, it can well be that I was just doing something wrong.

Might have to buy that RT809F device and experiment on the XL2720Z, since I know the Mstar ISP device can recover from bricking (I intentionally flashed a XL2720Z firmware into a VG248QE to brick it then flashed the VG248QE backup I made, which restored the monitor but it had a XL2720Z DVI EDID on it (displayport was correct) until I unlocked the service menu to remove the Asus write protect, and flashed a backup EDID via Linux--a huge PITA), but just in case you don't have it, the newest software is here :

Looks like you first install the 03/29/2016 build then just overwrite it with 08/10/2016 build.

BTW Strobemaster: can the RT809F flash a monitor that does not have a VGA dsub port?
I see a HDMI connector on it...(monitors can be flashed through HDMI?--edit, probably me being dumb again..)

The Mstar ISP device has a DVI port, but the RT809F flasher does not...

Because the XL2735 doesn't have a VGA connector (at least not shown on Benq's page).

*edit*
Strobemaster, is this the package I should buy?

Yes, I think that is the version I used.

Yes, HDMI works as well (HDMI 1 or HDMI 2, doesn't matter), even with max. speed. For VGA I had to use medium speed to avoid read errors. I connected the monitor just to the programmer (i.e., no PC) and it didn't make a difference whether I activated the input port (via OSD) that I used for programming.

I think it doesn't really matter as you just need the programmer. I ordered this from AliExpress.
