That is an HDCP issue triggered when using Chrome:

I think it's an NVIDIA driver bug because I've only seen NVIDIA users report this so far. The EDID override used to install the refresh rates should not cause HDCP issues, and people with 144 Hz monitors have reported this happening even without Strobelight.

Supposedly it only triggers with Chrome, so you can try Netflix with Firefox instead, or ask Netflix if you can use Silverlight instead of HTML5.

Ah I see - thanks for the quick reply! I think I'll just stick with LB on, it's too good to turn off haha

I really wish the colour on this monitor was better though...

All the more frustrating since apparently LB isn't working. Any other suggestions ?

I got my BenQXL2411Z yesterday. I took 144HZ on windows and AMD Driver on. Downlaoded Strobelight and did this http://i.gyazo.com/2198b334050430a2d0ed132776f99a4d.png
Rebooted, started Strobelight.exe...and after 15 minutes the .exe was still "initializing display"...what am I doing wrong?

Strobelight is not compatible with the BenQ Z-series monitors, but they have a strobing feature that can be adjusted using this: http://www.blurbusters.com/benq/strobe-utility/

It's not working even with SLI disabled and GeForce Experience/Samsung Magician removed? I'm not aware of any other issues that would prevent it from working.

Chief's working on a new beta which should work with the 2420G (in classic scaler Z mode), and which will hopefully work on the 2430T.

The T is a problem because while the 2420G uses the exact same firmware values as the 2420Z (if run in Z mode), the 2430T has some differences in both non strobe settings and an inverted strobe duty with a lower range values (intensity (duty)=1=brightest screen, least blur reduction, intensity 25 -dimmest screen/most blur reduction), but we don't know what the persistence ranges start (or end) at the moment.

For those with a 2430T or 2420G, you can still adjust all strobe settings through the OSD or service menu (2430T) or service menu only (2420G) if the beta utility version isn't working for you yet.

BTW a little (very old) trick:

If you have an Nvidia laptop that supports 3d vision, but without a DVI or DP connector (all Fermi mobile chips do, 400/500m series, unknown if "8800" class chips do or not, you can use the 3d vision emulator (emulator requires drivers OLDER than 311.xx)+ inf override, or even both (to turn the benq into an asus 120hz 3d lcd)+ DVI to HDMI adapter+either a custom resolution (MUST be custom; hdmi won't let you use >60hz at 1920x1080, but your monitor is actually connected through DVI, so it can accept the signal if you override the 60hz, but will obviously report a "incorrect cable" error), you can try 1920x1080, 48/3 front porch 32/5 sync width, 1138 vertical total/100hz, or 1149 VT @ 120hz, whichever one will display an image without an out of range error. Then run the 3d vision setup test with either the 3d vision discover (emulator) selected or the 120hz "Asus" (benq with override) selected. The benq screen will be wildly stretched out with strange colors and a cable error on the OSD, but the green lightboost light should light up (even with the cable error appearing). Then without ever unplugging the monitor, you can use strobelight to set up the resolutions on your AMD card.

Plus if you ever unplug the monitor from AC, just putting it in into the laptop will instantly recall the previous mode and unlock lightboost again without even needing to run the 3d vision setup (as long as you have the box selected to keep lightboost active in 2D). And you can keep using the laptop normally since it will use the regular settings if the Benq isn't plugged in.

This was the original way to get lightboost on the VG248QE for AMD users, before toastyX found the handshake for it (desktop Nvidia cards didn't require a dvi to hdmi adapter)

There are some (mostly 2d) games where Lightboost will look better than benq blur reduction, especially those which area pure 2d sidescroller based, and sharp contrast transitions; the per-line overdrive of Nvidia lightboost will make the ghosting/image overall look much better than benq blur reduction mode's much better colors (BBR lacks per-line overdrive, so even if you drop contrast to 0, you're either going to have regular ghosting (lessened at contrast 0) or inverse ghosting.

though in most 3D games, you'd use Benq blur reduction with a VT 1500 tweak, which in most cases will be better than Lightboost mode.

Lack of Lightboost mode is why Masterotaku on blur busters' forum won't ever consider buying a XL2430T (since 3d vision 2 was removed).

Hello thank you for a great program its nice to know i am getting the most out of my monitor

I have a few questions

I have a BenQ XL2720T

When i use strobing mode my 3d light on my monitor lights up, this is normal right and shows the program is working as intended.

However to get light boost to work i need to run games in windowed mode. Is this normal. The only game i can get working so far on full screen is tf2 but then i get a nasty flicking effect.

Normally when i launch games it will just turn its self off unless the game is running in window mode

If i turn the strobing off via the program am i still getting the benefits of reduced blur and stuff.

It would be nice if i could have the lightboost on all the time so i can get my color settings right

If any one has got any ideas if i am doing something wrong or got it set up wrong

Some extra info i use sli could this be a issue and also 120hz mode

Check the NVIDIA control panel under "Manage 3D settings" and make sure "Preferred refresh rate" is set to "Application-controlled" and not "Highest available" for your monitor.

If you install only 120 Hz, then strobing should be on all the time, but some games won't work properly without 60 Hz available.
