La scheda in oggetto è di fatto una originale scheda 2nd analog input (R7621055) modificata in modo che non prenda più il segnale dal connettore DB9 presente sulla mobo del barco (ingresso 3), ma dall'entrata DVI-D del schedina con chip Silicone Image HDCP che Greg collega direttamente alla scheda stessa. Vengono poi fatte tutta una serie di altre modifiche per migliorare e semplificare il percorso del segnale.
Ovviamente in qualche modo dovrà arrivare il cavo DVI-D/HDMI all'interno dello chassis....e qui il DIY di ognuno si scatenerà!
Vi allego in inglese (in attesa di tradurla per bene..si accettano volontari) un post di Greg.
" While the 1208 and 1209 Barco Projectors are excellent units they suffer from input problems. With all the new Digital Content being released DVI or HDMI is a must with today theaters. Long analog cable runs blur 1080p signals and direct digital always gives a much better picture.
So far to date we have tested every external and direct connect box port 3 device and had problems getting a good picture. We are all familiar with transmission line loss especially at 1080p. The higher the frequency‘s the greater the loss of transmission lines. After carefully analysis we also noticed that the Silicone Image video processor chip on external boxes has transistor amps on the RGBVH output Lines to drive the long cable 75 ohm lengths thus lowering the BW of the image and adding noise to the signal. There really is no advantage of using an external DVI box on a high end projector because you will lose the advantage of a Direct Connection. Ring or Ghost was always present because of cable issues and the ports on the back of the unit not being balanced also Port 5 has to go through a extra set of circuits that lowers the BW and port 3 while sharper and able to resolve higher BW seems to always Ring or Ghost no matter how good the cable is. We were determined to get rid of this Ghost Effect and we engineered a direct DVI to Port 3 solution.
This solution takes advantage of balancing each color with removing all the external transmission line balancing resistors mounted on the port 3 card. This way the DVI video processor chip can send the signals right into port 3 without adding noise from RGB, Vertical and Horizontal amp transistors. We then upgrade all the band pass and filter video caps with high grade capacitors. The effect is simply amazing not only was the ghost not present the actual resolution improved almost 95%. The photos below are untouched very high resolution close up photos. Pictures taken with a 1208 unit results even more extreme on a 1209. People always want to upgrade there projectors from an 8 inch to a 9 inch unit. From a 1208 to a 1209 however without the correct inputs, adjustments, calibration and screens there will not be an improvement. With the DVI MOD we arrived at a sharper image than a 9 inch with a much less cost. This Mod with a 9 inch is even sharper.
* 1080p verified
* Official HDCP Licence
* HDMI and DVI
* Removes all connections from Barco Motherboard and Port 3 to make the image extra sharp.
* Special power supply filters, and high grade cap filters are added to the DVI processor board.
* Special tuning of the port 3 card to ensure the correct color balance, vertical and horz stability.
* Removal of all 75 transmission line resistors to allow video processor to drive port 3 directly without the aid of transmission line "
