Got my card to 800x480, but now the DSCustoms LCD wont show it correctly

**rally1** · 07-26-2003, 10:12 PM

I am very confused, so hopefully it is something simple i am missing.
I have spent too many hours on this myseft, so now I need some help!

I used powerstrip to tell my Dell Inspiron 5000e to output (through the port replicator) 800x480.

I look at the settings, and it is set to 800x480.

The 7" LCD syncs, and selects 640x480. So I can see the desktop, but only 640 of the 800 pixels, if I scroll across I see the other 160!

WinXP pro
ATI Rage 128 Mobility (lastest and only driver)
The adapter says 800x480
When i click onthe "display" tab, it says CRT resolution 640x480.

If the card is putting out 800x480, why is the LCD defaulting to 640x480?

I have tried the laptop in every mode, CRT output only, dual etc, even changed it in the BIOS to load using the external LCD while booting (ie the LD on the laptop never comes on)

I tried it without the port replicator, just to rule it out, and the problem still exists.

I can't imagine it's bad screen, it does all the following resolutions:
640x480
800x600
1024x768
1280x1024
Doesnt do 1600x1200 even though the manual claims it does)

Next step is to try it on another PC.

try changing resolution and then changing back again, or maybe turning the monitor off and back on ?

That's really strange, rally1. It must be your PC, try another one.

Is there a way to force the LCD into the right mode?

I have tried the turn on/off, and changing resolutions, to no avail.

I have since removed/reinstalled all adaptor and monitor drivers, and it still won't do it.

I have to put powerstrip on my other (compaq) laptop, and see what happens there.

Maybe the refresh rate is set incorrectly? Try changing it between 60, 70, or 72.

OK, it's been at 60, but i'll try that too!
Thanks.

-No joy.

It sounds like you don't really have an external resolution of 800x480. The resolution is 640x480 with a "virtual desktop" of 800x480.

I guess so, does that mean my card cant do, but powerstrip thinks it can?

I'll have to get a screen shot to show you how the two settings are different.

One time when starting up, the LCD screen said it was in 720x480 mode, but then went back to 1024x768.
