3D with Lightboost at max brightness = 2D at half brightness
I never used 3D Vision 1, so I don't know how dim it is. I just got a 3D Vision 2 monitor (ASUS VG278H) and notices that 3D display with Lightboost at max is about as bright as 2D display with brightness set at 50-60 or so. Is that the way it's supposed to be? Or is my monitor's Lightboost not being as bright as it should be? I thought Lightboost would offer close to regular brightness.

Try turing up the brightness on the ingame settings too. Obviously its just a white balance type thing, but it helps.

But if you leave the in-game settings unchanged, is 3D with Lightboost at max brightness supposed to be only half as bright as 2D at max brightness? I just want to know if what I see is normal or not, so I know this is not due to a defective monitor.

I do not think lightboost is what we think it is. Nvidia 3D Vision1 glasses were closed most of the time, as in the cumalative time while in use. Samsung released 3D Monitors that used a new approach, their glasses were opened more over the cumalative time of use. They accomplished this by using a different switching mechanism where instead of a black frame being accomplished by having both lenses closed at the same time like the NV1 glasses, a black frame was inserted into the video frame sequence. At least that's the way I understand it. And, I think this is same technology that LightBoost is using.

That's why Passive 3D Displays are brighter. Both lenses are open all of the time. The light that is lost, is due to the FPR (Film-type Patterned Retarder) and the polarization filter lenses in the glasses. The inherent drawback with passive is that odd lines of resolution are displayed in one eye only and even in the other, which equals 1/2 resolution per eye. Athough the perceived image is close to full due to persistance in the eye/brain.

I remember the old, XP, drivers used to have a setting to up the brightness when 3D was enabled, if I remember right I used to set it around 1.2/1.3, the newer 3D Vision drivers don't have a setting like that anymore? Seems silly if it doesn't, it was a known problem 13/14 years ago. I don't really have this issue on my DLP, the TV handles that when in 3D mode pretty well.

The 3D Vision Blog covered this just a few days ago. Very enlightening: [url]http://3dvision-blog.com/8594-taking-advantage-of-the-lightboost-technology-for-2d-120hz-gaming/[/url] Basically Lightboost works by having the LCD's backlight go dark while the pixels are changing, and pulse brightly when the pixels have finished and the glasses' shutter is open. This allows both better brightness in 3D (by maximizing the backlight when the shutter is open) and less crosstalk/ghosting (by keeping dark while the pixels are changing). However, the article makes the point that the light output is reduced in 3D mode even with the glasses off, vs 2D mode with the backlight lit constantly. But, maximum brightness in 2D can be too much anyway. I would generally say I recommend against raising brightness levels in game options or in Windows unless you're sure it looks better. While it's called "brightness," really it's just raising the black level. Minimum brightness is increased, but not maximum brightness. Basically you can get an overall brighter image but at the cost of contrast.

It wasn't brightness, sorry, it was GAMMA, which increases the overall brightness not just the black level. :D [img]http://www.xvr3.com/msi/msi_install_11.gif[/img]
