Thread: 800x480 : Solution for Intel graphics

Does anyone has the DTD string for the Lilliput 629? I have upgrade my carpc to a Jetway J9F2-KHDE motherboard recently and now I can't use enable 800X480 anymore. I've looked into the DTD calculator approach, but I can't find the specs of the Lilliput 629 anywhere since I don't have the users guide and the Lilliput website doesn't provide the technical specification required by the DTD Calculator software to generate the new display resolution... hopefully someone with a similar setup can help!

Try the DTD string I posted above for the 619. The first two numbers are the refresh rate and you may have to mess with them. To figure out how to do that, read the Intel instructions linked in this thread.

Here's how it worked for me, for the 945 Intel mobile graphics and for a Lilliput 629 monitor.

- Install a display driver that does not already contain a 800x480 resolution. I just took the latest regular driver from the Intel site.

- Run DTD Calculator, and see if the two buttons in Registry Hack are active.

- In the Calculation tab, select the standard timing 720x480.

- In the Registry Hack tab, press More if needed, press Get Calculated, press Create Modeline, press write DTDs to registry. Reboot.

- Display properties, click to show all modes, select the 720x480 driver and see if it displays ok. You have now established the ability to add new resolutions with DTD Calculator.

- Run DTD Calculator again.

- Start with the 720x480 template in the Calculation tab, change the five most top left values to: 29.5 (MhZ), 800, 816, 880. 936. (It's everything 80 pixels more than before and a bit higher clock to get 60 Hz).

- Repeat the rest of the procedure with the new 800x480 resolution.

Thanks Geezer, I'll give this a try!

Thanks for the detaile explaination Geezer! I followed your procedure and was able to create and use a 840x480 display profile!!

But now I am facing two new problems:

1- Interestingly, the 800x480 display resolution does actually look less 'native' than the 800x600 that I was previously using. Actually, only the 640x480 seems to be giving me what I looks like a native display resolution without the usual font scaling artifacts experiences in the 800x480 and 800x600...

2- I set my display resolution setting to 800x480x32x60 in the RR Config utility (from Blue ZX3) and my RoadRunner Digital FX 2.5 skin is now cropping the bottom of the skin... does that mean that I now have to create a whole new sets of 800x480 skins for DigitalFX?

Thanks
Patrick

Set it to 800X480X32X75 instead. Lilli's run at 75Mhz best.

I use DigitalFx with 800X480 and I had to manually edit the RRconfig.ini. RRConfig.exe did not work right for me.

Is the aspect ratio correct? Is the "e" of the Internet Explorer Desktop icon a cirrcle or an ellipse? Should be a circle.

Assuming that the signal from the computer fills the screen and that no part of the signal is hidden:

On 800x600, you should get ellipses and vertical scaling artifacts.
On 800x480, you should get circles an no scaling artifacts. This is the case with my old non-LED 629. This is not the case with my new LED 629. It produces horizontal scaling artifacts. It's driving me nuts.

Darkman: Is your 629 the old one or the new one? The new one has the display area off-center so that the bezel is skinny on the left and fat on the right.

About the skinning issues, I don't know.

My 629 is display area is off center so it must be the new one.

BTW, I connected the 629 to an NVIDIA graphics card on my desktop system which offers multiple display resolution including 800x480 and I got the same results where only 640x480 looked like a native resolution... both the 800x480 and 800x600 resolutions had small (both annoying) scaling artifacts visible on text.
