After using DTD calculator in windows 7 when i set my timing to the page 1 timings and use the video circuit to convert H + V sinc. Im not getting good video. a bunch of colors scrolling across and it always has large black vertical bars on the sides.
Maybe i need your Driver. But i am able to write the DTDs to the intel registry. I notices in your 2 modelines the 17th bits are different. Ive tried both with no luck.
I'm sorry for the delay mate, we had heavy snowing and had to deal with it in some nasty ways :p
You can follow this : http://software.intel.com/en-us/arti...ntel-graphics/ to build the "custom" intel driver. Just delete all the custom modelines as examples from the .inf file and replace those with 800x480 and 854x480 I wrote at 1st post. Don't forget to enable them as it says so in that article.
You might need to uninstall and reinstall the driver (not just reinstall over). Play with it.
If you still can't work it out, PM me and we can solve this over teamviewer maybe.
A bunch of colors scrolling through your screen means wrong timings so you're not using the DTD. I never actually got to use DTD Calculator in win7. It simply won't work. You might want to delete first the DTDs wrote by DTD Calculator.
Okay, I have editing the intel DTD driver using your custom timings. but still get scrolling colors. So no matter what i have black bars on the sides, do you think since i have US version maybe its a different resolution. like 640x480?

I just am thinking that because of the black bars.
how did you determine the timing for your monitor?
also do you have power on the pin for pal / ntsc switch, its labeled a NORM?
At this point I'd use an intel gfx laptop or something with XP installed and step by step tinker with the old Powerstrip and DTD calculator. I wrote about how to use those together somewhere here.
The main problem with Powerstrip and intel gfx cards is that it cannot actually set the resolution but only the timings. So you set the resolution roughly with DTD Calculator and then tinker the timings with Powerstrip. When you get a clean image you take note of the powerstrip timings and convert them (you'll figure it out, its just deltas)
You can only run powerstrip on xp unfortunately.
The NORM pin leave it alone, it would set PAL mode if supplied with a 5k6 resistor to 12V.
The default mode is NTSC, which I used.
Also you might want to check the two vga pins for the sync (H & V) and also the C sync that comes out of the module.
If you have an oscilloscope check the output signal.
I checked the signals with a scope. My Horizontal pulse looks good but my Vertical is off. It is very low compared to the vertical sync which is throwing off my composite sync.
my Horizontal is around 5v while vertical is low...
The horizontal pulse is always blue. The first picture the red is Vertical, the second picture the red is composite.

After redoing the circuit. I have new results. Same Circuit Design, just a new plug.
I have ~5v on the Horizontal Sync and ~5v on the Vertical Sync. When i use the HV to C sync converter on page 1 it cuts the composite sync to ~.7v. Im not sure what the voltage should be?
I also pressed the dimming display and it seemed to Zoom the image. So by default i have black bars on the image, but when i press that button it fills out the monitor.

Thanks in advance
