Yeah i havent used mine in a while, generic CRT is still an option on the latest drivers, but it tries to drive a signal of around 240kHz to set the glasses up, ive never seen a CRT thatll go that high. With the GTX760 i cant use the 285 drivers, too old, so i resurected an older machine with the following specs:
Intel i7 950 LGA 1366 CPU
ASUS PT6 Deluxe x58 mobo
6 gigs or DDR3 in tripple channel
Nvidia 9800GT video card
I put Windows 8 on it because they were out of stock with Windows 7 PRO, and in all honesty once you have 8 set up, its hardly any different from 7 anyway. 3D working perfectly out the RGB socket and no issues playing 3D Blurays direct from the disc using PowerDVD 13 ULTRA and AnyDVD HD, the latter needed to spit out the HD and 3D signals from bought Blurays via RGB. It all works very easily without a hitch, perfectly smooth, very nice image. |
He I found an old x800gt. When I connect to the Barco I get the max resolution of 1700x1200 or something. Does this mean that this x800gt can not do 1080p or is it just drivers? Guess this x800 is a little to 'crappy'? |
It isn't cutting edge anymore that's for sure, it is about the same vintage as the GeForce 6 series, which I used with success for movies. Newer cards may consume less power or have better acceleration for movie streams, but that doesn't matter since any modern multicore CPUs are doing HD well without any GPU acceleration.
You have to check the 'override EDID information' (or something like that) in the Catalyst Control Center, then you can send out as high resolution as you want.

One full wave has an up and a down part. When you look at your monitor you see the up (white) and than the down (black). So one wave is two pixels. So if you express the frequency that is the number of waves per second you get 1/2 the pixel clock.
So if you look at specs of dac you will not see the pixel clock frequency but the wave frequency so if you see 90MHz dac flat you can be sure it resolves 180 MHz pixel clock. |
I doubt that ½ a wave frequence can be used to resolve a square signal, there must be some rise and fall time in play here.
Looking specs of different opamps dacs and stuff you would think its a piece of cake to do a 200Mhz pixel clock if the ½ analog bandwidth holds up.
I dont know any of the math involved here, im just wondering what kind of speed you need to define a pixel and get the right level/ amplitude on a 8 bit signal.

He you are right that you have not enough with 200MHz when you want 70MHz flat. What I read is that you need something like 800MHz for that but that is a wild number. The 1,4GHz opamps are only just flat enough to have 4 or 5 on a row and still resolve 1080p.
It is just that if you have a dac that says 90MHz it might actually be flat on 70MHz (1080p) because it is very very steep filtered. If you have a gaussian slope on an opamp we need to go much higher in frequency so you point is right. My point does not really add much to the discussion except to make the dac specs look less awfull.

I am sort of hoping that is has to little bandwidth flat because it looked worse than my ma vga adapter (1920x1200) did in the one on one patterns. I made an offer on a geforce 9800 gtx for 15 dollar(2048x1536)  Guess I can spend that on a gamble.

Why not just buy a new card that can go much higher if thats your goal? Im doing 3840x2160 out the display port with sending out 1920x1080 over HDMI, and can still send 2560x1600 out via the RGB.
Unless you want 3D with nvidia glasses, the the 9800 will be a good pick!

@Case: with the new htpc do you still use reclock and powerstrip or other tools? |
No, ive never used them. Nvidia has it in their drivers anyway if i really wanted to do something.

I have a small issue with the projector: some parts of the green image coming from the green tube move slightly left and right, it happened after a long play with the Xbox 360 at a resolution of 1680x1050p 60hz. Now it's always like that. I've thought that maybe the problem was the RGBHV-VGA cable or the video cable but after removing them the problem remain.
Could it be a problem due to some bad solder? Or maybe some capacitor that don't keep charge?

If it is a drift with temperature than it is probable a bad capacitor but than it would only go one way.

The problem is what capacitor is bad and effectively the dissipation fin of the main board (the one that you see just under the chassis) gets very hot, i can't keep my hand on it for long so i guess that it's more than 80° Celsius. Is it normal that it get that hot?

Its not capacitors.
Clean the yoke fittings where they connect to the DEF board. Its quite common, and no issue to be concerned about.
Yes that board gets hot. Its no big deal. Run it at 1920x1080i instead.

Yes, I have a very similar one. It works fine with CRT but since it is quite old equippment it has very limited compatibility with modern hardwares. To name few, the latest nVidia driver which supported this kind of 3D was the 162.50 driver (only for Win XP), and the latest compatible card was the G80 based GeForce 8800. The shutter glass definitely shifts the colors towards to the colder tones, all in all it's a good fun.

Is it possible to watch 3D Movies with it, at least at 1024x768 or with interlaced 3D? And have you got some tips for a cheap Nvidia graphic card? I have got only 2 old ATI and a Matrox at home. I searched a bit on Ebay and i've found some Nvidia MX440 that are very cheap, could they work with it?

Yes I was able to watch 3D movies at 1920x1080i 96Hz, with the so called stereoscopic player (set to nVidia 3D vision output). The geforce 4 MX440 is an AGP vga card, motherboards with AGP connectors are usually not able to handle modern CPU-s, without that, you are limited to 720P ripped movies at best, that is about the top what those computer can do. For HD movie playback you need a more powerfull computer with multiple cores and PCIe connector, anything from the Geforce 6-7 series would do this kind of 3D, those cards should be very cheap too.

Ok, thank you for help, gjaki, I've found this GeFORCE 6600 that seems very nice (with also a cool pic of Doom 3 on it) at less than 20 euros: http://www.ebay.it/itm/GeFORCE-6600GT-PCI-E-128-Mb-DDR3-/161421300653pt=Schede_video_per_PC_e_Server&hash=item25957593ad
I guess my Tower PC should works fine with it even if i don't know what is that connector on the up, I ask to the seller.
Do i need to use Powerstrip, or Custom Resolution Utility to get 1080i in 3D or i need to use other softwares beside the driver that comes with the glasses and the VGA dongle?

Look around if is there any local (to you) computer forums, the GF6600 cards are now rather considered to "give away" items, I wouldn't pay 20€ for one... You don't have to use any special programs for custom resolutions with nVidia cards, the driver has this feature built in.

I wouldnt pay a cent for a 6600GT, they are well over their time and they dont do 3D. Id aim for a 9800GT at the least. Its usually always a single slot card too, and very quiet.

Case, he is looking for a card to match to the linked 3D kit -which is essentially the same wired as mine.
