I think there was one or two other folks doing Polarized/Dual Projectors-

Cypress is coming out with a 3D demultiplexer that will run around US$400. The set will split a 3D HDMI 1.4 signal into left and right HDMI 1.3 outputs at 1080p60Hz- just right for CRT. My understanding is that Optoma's 3D-XL unit will do the same thing at about twice the price. The Cypress CH-322 due in April, we'll see how it works.

My last communication with Lumagen indicated that it is very unlikely that they will be supporting dual output. The other option I see bandied about is decryption on an HTPC. Frankly I wouldn't want to be caught with software like that. The music industry had a lot of fun suing people for $$$, I wouldn't put it past the movie industry to try to do the same.

Thanks, Mark

Thanks for the answer Craig,

I understand that today 3D resolutions that are available on Lumagen firmware are using 720 active lines scanning only. This is still interesting to see the result in this 'low' HD resolution on the G90 in 3D. Once I'll get the BDP-93, I'll try it Cool

I see that the point is less ghosting as possible and for that goal : big V_Porch (blanck) settings are needed to let the green phorphore persistance enough time to decrease.

- For 2.35:1 3D material on the G90, we may be able to keep 1920 pixels H_active while using 817 lines V_active if we can ensure that we keep V_Porch blanking around 400 lines (so ~1200 lines V_total).

- For 1.78:1, I see that if we're trying to keep 1080 V_active lines (so 1500 lines V_Total), we have no other choice than reducing H_Pixels (active) but going lower than 1280 pixels is pointless for me since we already have 1280x720p96 3D resolution, yes ?

I think that keeping the H/V pixels/lines ratio close to 1.78 is important for the PQ, don't you ?

So, for 1.78:1 AR we may choose a 3D custom resolution with something V_Active around ((1080-720)/2)+720 = 900 lines. From this value, we should choose H_Active around 1600 pixels. Ending with a custom 3D res. of 1600x900p96 (with 1300 V_Total) which is still a better resolution than current 1280x720p96. Is this compromise makes sense ?

Later

John

Craig,

Is there a trick to getting the Samsung glasses to sync with Gen2 emitter ?

I am unable to get my brand new SG2100 glasses to work.

If I use them with a Samsung tv they work fine.

With the Gen2 emitter plugged in to the Lumagen dongle and set to orange led flashing. It's like the Glasses will not switch on at all.

If I change to orange solid mode my nvidia 3dvision glasses fire up immediately.

Could you give me a ballpark delay figure that gets your Samsung glasses running please.

regards

Alan
