|
|
|
I just bought one of the 3D-Theatre boxes, and I want to run my Marquee 8500 at 60hz and then 120hz when playing 3D content to see if I notice a difference in quality. How do I change the PJ from 60hz to 120hz? I went through the menus but didn't see anywhere that listed options for the refresh rate.

Sorry man.....but I believe your source has to be the device to run at 120hz. But I would not go past 72.

You ned something that will scale to 720P 120hz You can not run full 1080P 120hz

Might be able to with unknown mods. Ha ha Eisermann claims this sh*t on his Barco mods.

I ran some test a long time ago with my Marquee at 120Hz and my HTPC, was a thread.
So can be done.

LOL.. Sure it can be done.. But you cant resolve that framerate.. You need a bit more bandwidth.. it will role of much to early.
Unless you run a low resolution like 720P and it still wont resolve it fully

Looked pretty good on screen with movies, no not as sharp as 75Hz and 72Hz,

Guys
96hz is widely used in computer-generated 3D; try that if the source can manage it. However, you may have lag issues on the green unless your green tube is P43

720p at 96hz refresh actually uses less bandwidth than does 1080p at 60hz. About 70% of the bandwidth, actually. So, Tim makes a really good point... If your source and 3D processor can take a 3D film source and output 720p/96, that could be a pretty good option for CRT.

I think the Marquee will do fine with 720P 120Hz, it will match the bandwidth of the machine.
720P 96 hz will maybe still be a bit high for the low bandwidth machines like Barco.
I dont know how 3D looks on a CRT, ill guess 96hz will flicker as crazy as 48hz 2D
60 hz is almost free of flicker.

You should have very badimpression on barcos... 
I show you how my NEC (marketed bandwidth is 100MHz) have done 720P-120Hz.

Its always nice when the bandwidth is better than promised..
But when the Barco 909 wont even resolve 1080P 60 Hz, around 150Mhz, i doubt it will do 720P 120Mhz, guess around 140Mhz
Try shoot a pic of the SMPTE pattern on HD Basic, with all 3 tubes in different resolutions and framerates, Would be fun to se how the NEC holds 1080P 60 hz.

What about a green shot with 1080P-60-75-85Hz?

Thats ok, but all colors shows better that it holds the bandwidth with no peaking or roleoff on all tubes, like they have different gain they will respond different if the bandwidth is not perfect.

I understand you, but on a NEC it's a bit hard to take fun pictures like this because if you send a new signal to it, it will load the convergence data from a default area, and in my case it loads a sh!t color balance with sh!t convergence
pictures are actual 1:1 cutouts (except info page)
