Either BenQ would have to implement this, or as Falentyne said, someone would have to implement it through DDI/CI (if it even allows it?). Honestly, I can't see why nVidia or Microsoft don't directly implement strobing into their drivers or into DirectX. nVidia started allowing graph based tweaking of voltage on their new GTX cards. It would be nice if you could just tweak the overdrive parameters like this. But if they are configured properly, I guess it wouldn't offer much.
You have to remember that G-Sync is a separate chip that does all of the magic. Benq isn't about to change/fix their overdrive any time soon, that would require real work being done.

Having a sort of control panel for your monitor would be pretty sweet but it would require some sort of standardization and again, that would require too much work :lol:

Most monitors don't support strobing unless it has a G-Sync module. Although someone has had both work at the same time, he's not sure how.

Actually, it seems maybe strobing the backlight is not that difficult. All you might need to do is insert a black frame at the proper intervals and that will reduce persistence. Example:

This does strobing via software. So technically, it should be possible to have G-SYNC on and then have the strobing done in software. This might add some overhead (not much, though). I was thinking that maybe Microsoft should just add something into DirectX that does the strobing. That way, anything with G-SYNC automatically works. Even 60hz @ 60fps could strobe, however there would be a perceptible loss in brightness and it would flicker. But alot of motion blur would be gone.

Oh, just black frame insertion? yea that would be pretty cool for playing 60fps console ports on a PC with 120hz monitor.

There are already a few emulators and DLL injector stuff that you can use to get that too work, but nothing that mainstream.

The problem with black frame insertion is you STILL need a strobed backlight to get smooth framerates at the FPS being "half" the monitor refresh rate. So a 60 FPS locked game at 120hz + Black frame insertion=smooth, but only on a currently strobed 120hz monitor (120hz ULMB in this case, or Lightboost/Benq BR).

So it's not exactly the same as 'strobing', as In addition, you have to deal with how long the frame is 'off' and 'on' as well (persistence). Would love to see more development in that, though.

But dynamic control of overdrive when there are three overdrive settings (Off, High, Premium) is 10 kinds of worthless.
