800x480 on intel 945GM/GMA950 - is it possible?

**Giuliano** · 04-20-2007, 10:29 PM

Hithere:

That's good info.

Please attach the Xenarc and repeat, I'd like to see what it reports for that.

Try to attach it as a text file instead..

The "Modeline" entry actually tells me the parameters I'd need to drive your laptop LCD correctly:

Modeline................ "1680x1050" 119.230 1680 1728 1760 1840 1050 1052 1058 1080 -hsync -vsync

First number 1680x1050 is the horizontal and vertical active lines..

119.230 is the pixel clock in Mhz.. 10khz format for IEGD would be 11923 decimal.

The rest of the numbers are start and stop pixels for the other timing parameters.. it gets somewhat complicated.

Those details are also in the EDID Base hex numbers, but that's MUCH more difficult to decode.. some of the bits are mixed together.

I think we're getting much closer to a working IEGD driver build for laptop displays.. if you don't mind being a guinea pig..

Is your system a laptop?

Please describe it further..

Also, grab the Moninfo program from Entech Taiwan, and run it with your external display (Xenarc?) attached.

Attach the Report here as a text file (.txt).

It seems people are getting these errors when they have a configuration with display ports other than just Analog VGA, such as DVI, TV Out, or laptop LVDS LCD panels.

And yes, try the last [NonEDIDMode_AddSWSettings] parameters, using the standard Intel driver package from their web site.

The byte string is the one that starts with 96,96...

I think you may have a better chance of that working with your G965 chipset.

The NonEDID settings may only show up if you have a non-EDID (possibly?) monitor attached, such as the Xenarc.

i have no idea if there are similarities with the other intel chipsets, but it's worth asking right?

thanks for the good work

Certainly worth asking..

The 810 is an older chipset, and it's not included in the latest IEGD 6.1 package.. but I think it may be included in the older 5.1 package.

Let me look into it..

Edit: Looked into it.

The IEGD 5.1 driver package for the i815 chipset series also includes these i810's:

i810
i810DC
i810E

So it looks like you're in luck.

In the mean time, grab the Moninfo program from Entech Taiwan:
http://entechtaiwan.net/util/moninfo.shtm

Run it, save the Report as a text file (.txt), and post it here as an attachment.

Make sure that when you run it, you have the standard Intel drivers installed (or the Vendor's, such as Dell's), and have all the monitors you want to use attached to the system.

Also, I'll need details on your system..

Laptop / desktop, number of video ports.. which ports you want to use, etc.

My computer is not a laptop. It is based on a Gigabyte GA-965GM-S2 motherboard. Veiwsonic 19"crt hooked to it now, when installed in my truck it will have a Xenarc700tsv.

Find the file montor.txt from my computer with the Viewsonic attached.

Do you also need me to hook up the Xenarc and get the monitor info?

**koabi** · 04-20-2007, 11:20 PM

Mine's a desktop with one VGA output - it is currently hooked up to the Xenarc 700TSV and that will be the only screen it uses.

monman didn't really report that much information because the xenarc doesn't have PnP drivers (to my knowledge), but it's attached. Let me know if you need more info

Good - let me work on the older IEGD package, and I'll let you know in a few days..

**Giuliano** · 04-20-2007, 11:28 PM

Okay, I've confirmed that the Xenarc won't provide any EDID info, which is what I thought.

How many of you, when you were trying the IEGD driver packages or the standard Intel driver .INF modifications actually had the Xenarc attached to the VGA port?

What I suspect is that the 800x480 settings encoded in the NonEDID keys only show up when a monitor is attached that does NOT provide EDID info.

Most "normal" LCD displays these days provide the EDID timing info over the VGA cable, and hence override the NonEDID settings.

Felix509, please try the Intel driver .INF mod as listed in a few posts ago, the one starting with 96,96.

Before you install the drivers, attach the Xenarc instead of your Viewsonic LCD.

Hithere, I'll build a new driver package to account for the LCD panel soon.

**Felix509** · 04-21-2007, 06:17 PM

Good deal, i will try it as soon as i can, maybe tomorrow..

Will this mod make 800x480 the only resolution, or add 800x480 to the list of available??

Thanks

It should add 800x480 to the list of standard timings, such as 800x600, 1024x768, etc..

With a non-EDID monitor attached, 800 x 480 should show up in the list.

You may need to go into the Advanced section and pick the mode from the list.
