This really makes me question the whole point of this monitor. If you could just get the XL2540 and have the option to enable/disable Blur Reduction then why would you get the XL2546 which forces you to have Blur Reduction (DyAc) on at all times? Obviously there must be a difference between Blur Reduction and DyAc. Still waiting for someone to investigate this... Btw it took them over half a year to make DyAc work on this 240Hz panel.
Also if this is the new top model of their 240Hz esports lineup then tournaments and pro players should be getting this monitor eventually. Many, if not almost all, pro players (at least in CSGO) always play with Blur Reduction disabled. I'm guessing that's because of the lower brightness, added input lag and the strobing potentially causing headaches and so on (I remember when they had pro players talk about how good the new flicker free monitors were a while back. Now they're forcing it back onto them?).
So basically all of these players will be forced to play with these things that they don't like?
I would really like to know the answers to these questions.
1. What is the difference between BenQ Blur Reduction (XL2540) and DyAc (XL2546)?
2. Is this difference worth the extra money and not being able to turn it off?
3. Is there any way to turn DyAc off via Software? And if so, would that just turn it into an XL2540 or is there any other difference between the two monitors?
4. Why does BenQ/Zowie not market Blur Reduction on the XL2540 but they market DyAc on the XL2546?
Edit: I'm stupid. The XL2540 doesn't have Blur Reduction. That pretty much answers half of my questions.
dyac can be disabled in the service menu. This goes for the XL2546, XL2540 and XL2735 as well.
On the XL2540 it's called "blur reduction."
To open the service menu you need to power on the monitor holding down button #4 then pressing the power button and releasing button #4 when you get a screen. then button #4 (or 5) enters the service menu.
The factory menu (with the overdrive gain) settings is button #3+#4 held down together while powering on. Then button 5 should enter the factory menu.
The XL2540 DOES have blur reduction but it's OFF by default, instead of on. Service menu lets you enable it.
What I *REALLY* need to know is, if you DISABLE DyAc in the service menu, does Freesync (or adaptive sync) become available in the AMD Radeon Settings panel....the scaler supports it.
