high transmittance glasses
Hi guys
I recently upgraded my projector dlp link glasses from viewsonic pgd-150 (30% transmittance) to pgd-250 (60% transmittance). The 3D vision brightness boost was perfect for pgd-150 but is way too much for my new set of glasses (darks are grey and and everything looks overexposed)..is there a way to adjust the brightness settings to compensate for the high transmittance?

Thanks in advance!

Hi there. I found that forcing the gamma to .75 instead of 1 in the nvidia control panel display settings was kind of offsetting the higher brightness in 3d vision mode in the most efficient way..can any techie out there confirm it is the best tweak he can think of ? Thk you

...been thinking about this, you are right about the gamma variation, it's inherent just like colorshift, but certainly not right about the 65% transmittance figure, I don't believe that, that stuff wouldn't even rely on polarization anymore.

i agree with you that this seems crazy as i cannot image how this could be more than 50%, but this is just what is written in the manual (60% not 65%) and all i can say is that they are significantly brighter than the other ones...maybe they found an active process to enhance brightness going through each lens when it's open...i really can't tell....thanx anyway to have confirmed that gamma is the parameter to play with!! /thumbup.gif' class='bbc_emoticon' alt=':thumbup:' />
