Could you install the softmccs application open it and screenshot it for me. My BenQ xl2411t does not show anythingin the "Manufacturer Specific" section. I assume this is because I have an AMD card.

Correct. It's turned on through the Nvidia Control Panel Steroscopic 3D section which requires an Nvidia card to enable the software and activate Nvidia 2 Light Boost feature which your monitor is capable of currently but unable to be utilized.

See Light Boost was created to enhance 3D Vision lighting when viewing 3D movies and 3D gaming. Nvidia has some great 3D Vision going on currently. This Light Boost feature inadvertently we've found has a dual purpose. thumb.gif

Nvidia Control Panel - 3D Steroscopic page.




Through 'Test Steroscopic 3D' one checks the option which enables Light Boost even when viewing movies, streaming. Gaming at 120 Hz with LB enabled even when not in 3D creates zero motion blur as per explanations provided in previous posts. biggrin.gif

And to make one small correction to OP title.....it's not Light Boost 2 it's Nvidia 2 3D Vision which is their second improvement of 3D that includes their first version of Light Boost. It's not a second version of Light Boost fyi.

Welcome! Glad to see a moderator join in the fun;

Yeah, I realized that sometime back around page #10 or so (several months ago); but I couldn't edit the thread topic anymore (I can edit posts but not topic threads after a time period). Since you're a mod, mind if you change "LightBoost2" to "LightBoost"?

Theoretically yes, but it's a software based trick necessary to make this work (blacking out every other refresh: Software-based black frame insertion) --

It has now been added to MAME (beta) and WinUAE (beta), the arcade emulator and the Amiga emulator, beta download links are found in Comments at www.blurbusters.com/mame

For a universal black frame insertion app at 60fps @ 120Hz that works with all software, someone needs to write a driver hack or a software-based "always-on-top" flickering window overlay (flickering 60 Hz) that is super-precisely synchronized to the refreshes, to do the equivalent of blacking out every other refresh at 120 Hz, to produce the necessary black frame insertion effect for 60fps material, so we can keep the LightBoost zero motion blur effect for 60fps stuff. It's technically doable, but requires someone to program some appropriate software to pull this off. I suspect it will be easier to do for windowed apps and simple maximized windows than for full screen Direct3D apps (which override other windows' ability to pop on top), but should be possible to program it to make it work for full screen apps.

This wouldn't be necessary if LightBoost could be hacked to operate at 60 Hz, but we're lucky we've discovered a way to make the zero motion blur effect happen for 60 fps applications while keeping 120 Hz refresh, simply by blacking out every other refresh (software-based black frame insertion).

I already know that and fully understand what Lightboost does. What I wanted was to see if the DDC/CI command is visible with an Nvidia GPU via SoftMCCS in the "Manufacturer Specific" section.

Yes if you hotplug from a Nvidia rig to an amd rig but directly NO.

You could buy some really cheap used NVIDIA card and plug it in to get your monitor to stick to LB really quick, then swap the monitor over to the AMD card.

Yep, a $50 nVidia card activates LightBoost for a $600 AMD card thumb.gif
