19" LCD looks garbage...

...well, the display seems fine. It's a Hanns-G 17" Widescreen LCD that I picked up for $137.99 from Canada Computers for my PowerMac Dual 800 Quicksilver. I have the stock 64MB nVidia card installed and the LCD plugged in using a VGA cable.

I'm at 1152 X 870 (75 HZ) and text is sometimes hard to read, images are washed out and stretched to fill the screen. I had a MacBook with a 13.3 widescreen and things were nice set to 1152 X 720, but I can't get this resolution on my LCD using the stock video card.

Would getting a ADC adapter and hooking this flat panel to the DVI port make images and text sharper? Can I use this LCD widescreen with my PowerMac?

Help!

The image is offset because 1152 X 870 is NOT the native resolution for the display in question. It isn't comparable to your MacBook as the screen sizes differ by 4 inches (and their native resolutions are also different). Change the resolution to its native resolution for best results of 1440x900, which will probably resolve your issue. If that resolution is too large for you, consider downsizing to a smaller LCD -- downsizing LCD panels in resolution (outside their native resolution) will result in poor image quality. Switching the panel to a digital (DVI) connection helps to some degree, but if you're not using the display's native resolution, switching to a digital connection will not fix all your complaints.
The native resolution for widescreen 19 inch monitors is 1440 x 900.
If your card can't achieve that, you may want to go to a 19 inch non-widescreen.
$137 for an LCD is cheap.

He has a 17-inch LCD, not a 19-inch. However, 1440 x 900 is still the native resolution for a 17-inch WS LCD. (And his video card does support that resolution.)
Ummm... look at the thread title. Is there such a thing as a 17 inch widescreen?
edit::baby: Why yes there is, I stand corrected.

"It's a Hanns-G 17" Widescreen LCD... Which seems to contradict the thread title. However, look up the model on CanadaComputers.com -- it is indeed a 17-inch widescreen. You should know that the 17-inch iMac is widescreen... so yes, they exist. ;)
Ok.

Switched to the LCD's native resolution of 1140 X 900 (75HZ) and here's what I get:

- much clearer screen with respects to the problems noted above
- no more stretched screen!

BAD:

the whole screen has shifted to the right. I can only move the H-position so far to the left leaving a 1/4 of the screen in black.

Ideas?

Restart the computer. Once you hear the chime, press and hold the following to reset the PRAM:

Command + Option + P + R -- until you hear 3 more chimes (display will stay black).

Let go on the 4th chime, and let the unit boot normally. See if it solves your issue. Also, before zapping the PRAM, turn the display off. Once the PRAM is zapped, turn it back on. Resetting the PRAM can often resolve scrambled video settings unless the LCD is at 100% fault and the fault has nothing to do with the unit it's plugged into (until you try, you can't say for sure).
I plugged the LCD into my Intel Mac Mini's DVI port and the machine instantly set the LCD to the native resolution of 1440 X 900 without a hitch! So, I guess that means a DVI adapter for my PowerMac or a video card with a proper DVI connection.

Will the ADC connection work? Is the ADC the same as a DVI port?

ADC carries the same kind of signal, yes, but of course you'll need an adapter. (ADC-to-DVI.)
