Problems with graphics driver - Intel 82845/G/GE/PE/GV

[Progress City]

I have a Pentium 4 motherboard with an onboard Intel 82845 graphics
chip set. I recently purchased a 20" LCD monitor that natively
supports 1680x1050.

Is there any way to get the 82845 chipset to support 1680x1050?

Buying a new graphics card is not an option right now. The motherboard
doesn't have an AGP slot, and I can't afford the cost of a new
motherboard at this time.

Does it have available PCI slots?
I don't think that video bios supports the given resolution...

I think these are supported:

- 1280x1024, 5:4 (1.25:1)

- 640x480, 4:3 (1.33:1)
- 800x600, 4:3 (1.33:1)
- 1024x768, 4:3 (1.33:1)
- 1152x864, 4:3 (1.33:1)
- 1280x960, 4:3 (1.33:1)
- 1400x1050, 4:3 (1.33:1)
- 1600x1200, 4:3 (1.33:1)
- 1792x1344, 4:3 (1.33:1)
- 1920x1440, 4:3 (1.33:1)
- 2048x1536, 4:3 (1.33:1)

- 1920x1200, 16:10 (1.60:1)

- 1280x768, 5:3 (1.67:1)

- 1280x720, 16:9 (1.78:1)
- 1600x900, 16:9 (1.78:1)
- 1920x1080, 16:9 (1.78:1)

- 1280x600, 17:8 (2.13:1)

Otherwise - you will need a different video card - and PCI video cards will
work well enough.

Thanks for your quick reply!

Yes, it appears that my chip set doesn't directly support 1680x1050,
however I found instructions for getting 1680x1050 to work with
another Intel chipset and was hoping someone would know how to do the
same with mine. (see below)

Thanks again!

-------

These instructions won't work with my card - does anyone know of a
similar trick for the Intel 8245?


1. Downloaded the newest drivers in zip format from intel's website
2. Edited the igxp32.inf file as follows:
a. Changed HKR,, TotalDTDCount, %REG_DWORD%, 0 to HKR,,
TotalDTDCount, %REG_DWORD%, 5
b. Changed HKR,, DTD_5,%REG_BINARY%,
00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00,00 ;Fifth DTD
to
HKR,, DTD_5,%REG_BINARY%, 79,39,90,40,62,1A,
25,40,68,B8,3,00,00,00,00,00,00,1C,37,01 ;Fifth DTD
3. Ran the setup.exe
4. Restarted the computer
5. changed the resolution to 1680x1050
6. Jumped for joy!

you will need to update the driver for your chipset. this should work..
go to this site for the driver..

altho, i woulod recommend getting a video card. both AGP and PCI cards are
cheap now a days..
