That said, I do not recommend mixing and matching LightBoost / non-LightBoost monitors in spanning mode.

You are the man!
When running them (a VG278HE for center and two GD245HQ's as sides) in non-light-boost mode, they did run in triple monitor no problems at all. Abit 120Hz (the Acers max frequency) BUT because they are both 24 inch and the center is 27 inch, and all 3 are running the same resolution, none of the spanning lined up.. For instance, a box that was 100mm square on the 27 inch, when panned across over the bezel to the 24 inch became 75mm (roughly). So it pretty much negates the want to span at all. It just doesn't all line up properly for the full effect. I ditched the whole idea. I'm waiting to pick up my VG278H and VG278HE to pair up with the HE I already have. Should get them tomorrow..

I haven't upgraded anything else and it only happenend when i played games such as cs:go or world of warcraft, but i don't think that my GTX580 is under high load with these games. Atleast i never had this problem with my old Monitor and the same gpu in these games.


I searched a litte bit in this thread and found this post, it looks like im not the only one with this problem:

but i found nothing that could fix the problem

Keep tracking that thread and the blur busters site: http://www.blurbusters.com/zero-motion-blur/lightboost/
its the monitor inf file in addition to the drivers that cause the problem.
Soon it will be fixed! thumb.gif

ToastyX Strobelight is much easier to use but may not accomodate all special use cases.

Thanks. I have some additional questions:

When I install the the new ToastyX Strobelight Beta utility, why do I need to add up to four resolutions? If I want to game in 3D, do I need to turn off the utility first?

If I set 121Hz then I press Ctrl+Alt+Minus, then it will just turn off Lightboost but will retain the refresh rate of the screen at 120Hz? 121Hz is just to let the display know that it is being set to a non-supported refresh rate, is this correct?

Also, let's say I can only get up to 80fps in a specific game would it be better to use 100Hz strobe instead of 120Hz since 80fps is closer to 100Hz?

Is using BFI (software strobing) to achieve 60Hz Lightboost effect bad for the display? Is this the reason why it is not recommended?

I finally used the UFO test and I am seeing a lot of framestutter up to about 40 and then it will be fine for a bit. FPS will drop from 120 to about 80 then back up to 120. Could this be an issue with running the monitor via HDMI at 120hz? I tried with the DP connection and it still gets a lot of framestutter.

Framestutter of this type is caused by the browser, not the monitor. Please try a different browser -- www.testufo.com/browser.html (e.g. Chrome vs Opera) and if using Chrome, make sure everything is enabled within chrome://gpu for full motion fluidity. You need a GPU-accelerated web browsers to run TestUFO smoothly, and some browsers still has bugs with these motion tests.

I did use chrome since IE doesn't support 120hz. Here is what chrome://gpu says:

raphics Feature Status
Canvas: Hardware accelerated
Compositing: Hardware accelerated on all pages and threaded
3D CSS: Hardware accelerated
CSS Animation: Accelerated and threaded
WebGL: Hardware accelerated
WebGL multisampling: Hardware accelerated
Flash 3D: Hardware accelerated

Rasterization: Software only. Hardware acceleration disabled.

Problems Detected
Enable panel fitting capability on ChromeOS only on IVB and SNB Graphics Controllers.
Panel fitting is unavailable, either disabled at the command line or not supported by the current system.
Accelerated rasterization has not been enabled or is not supported by the current system.

For perfect fluidity in www.testufo.com motion animations, try:
-- Make sure nothing is running in background (Task Manager 0%)
-- Make sure no other apps or browser tabs are running. Browser animations are very sensitive to other things running on the same system.
-- If you still have problems, you may need to run single monitor temporarily (as recommended by www.testufo.com/browser.html ...)
-- A fresh boot can help too.

TestUFO is undergoing beta testing, and only about 90-95% of gamer systems (with a GPU) seem to run it smoothly -- there is about 5% to 10% of users that seem unable to run TestUFO smoothly even in a browser.

Depends on VSYNC ON or Adaptive VSYNC.
VSYNC OFF -- try using highest refresh rate
Adaptive VSYNC -- try using framerate closer to average refresh rate

Adjusting to use FXAA instead of FSAA can also give you a big framerate boost. Changing certain settings like decreasing shader detail by one notch, and decreasing view distance by one notch, may give you what you need to run 100fps instead of 80fps, etc.

Do you mean VSYNC OFF or VSYNC ON? I don't understand, VSYNC only works if your fps exceeds your set refresh rate, right? So with my example of 80fps and my monitor set to 120hz, VSYNC ON would practically do nothing, right?

How about for my other questions especially those concerning BFI?
