Not Running at Navite Resolution

1280x1024 is a 5:4 resolution and 1024x768 is 4:3, so unless your graphics driver or the monitor is able to maintain the correct aspect ratio, the image will be slightly stretched vertically.

The viewable area of the A90 is approximately 18", so the same resolution on a 19" LCD will appear slightly larger (less so if it is not stretched).

As for image quality due to scaling of the lower resolution, I think you would need to see this for yourself, but maybe someone with a 19" LCD can try it for you. You may find that 1152x864 on the LCD is OK.

BTW...
A 19" LCD at 1280x1024 has a pixel pitch of 0.294mm, one of the largest of any size LCD display. In comparison, 1024x768 on the A90 CRT gives a 'pixel pitch' of 0.351mm.

I presume you are aware that you can increase the displayed text size in Windows.

Hope that is some help.

Hi, gpro, thanks for the reply.

I've always had trouble understanding the conversion of going from variable pixel (CRT) to fixed pixel (LCD). I can do the math, but there's so much to consider, plus, I can never remember the aspect ratios.

Speaking of CRTs...

The card that I use on the A90 (I don't remember the brand/model) does have a setting for 1024x768, and the picture looks fine. It also has a setting for 1280x1024, which very, very nice.

I'm not sure I understand what you mean by "unless your graphics driver or the monitor is able to maintain the correct aspect ratio...", because my card also has other 'strange' resolution settings (I'm not sure if they are 'standard' aspect ratios, but when I try to run the A90 at some of these, they are stretched one way or the other. What I get from your statement (still speaking of CRTs), and from what I've experienced, is that even though one's card might handle many resolutions, they will only look right if your monitor can handle them, too. I assume this has to do with many factors of the CRT, such as the cathode ray gun, the coating, and the drivers within the CRT itself.

Speaking of LCDs...

I'm supposed to have a Dell E520 Core 2 Duo desktop delivered today. The E520 is no longer made, but I wanted the BTX case, so I ordered it from the Dell Outlet. It's pre-loaded with Vista Home Premium, and I'm not sure how this XP person will like it. If I don't, I'll get another hard drive and install XP. It has a 256MB nVidia Geforce 7300LE TurboCache video card. I don't know the specs of this card, but assume it handles many more resolutions that I'll ever use, including the 'standards' such as 1024x768 and 1280x1024.

Yesterday I bought an LG1933TR:

With some coaxing, I was able to get the salesman to hook it up to a digital output (rather than the analog, in-store display) so that I could see it work at it's maximum resolution. It looked pretty good, but we couldn't figure out how to use Vista to set it to 1024x768, so I figure I'll just try it at home when my new machine arrives.

One thing I did notice in the store was, and you may have some knowledge about this, is that most of the LCD monitors, including the LG1933TR, whether standard or widescreen, showed some bleeding of greens and purples, and usually when displaying certain letters (I guess because of how they are laid out against the LCD pixels). For instance, the lower case 's' always showed green flaring around it. I couldn't eliminate this when trying to adjust the LG, but I didn't spend that much time with it. Again, I'll mess with it at home.

re aspect ratios:
CRTs are 4:3,
17" & 19" LCD are an unusual 5:4
widescreen LCDs are 16:10.

Ideally you want your screen resolution to match you monitor aspect ratio, and with LCDs, its native resolution. The nVidia graphics driver has options to control how non-native resolutions are displayed (under Display > Change Flat Panel Scaling). You can also set custom resolutions. Hopefully you'll find a combination that works for you.

Many thanks.

My machine was delivered yesterday, and I should have time to 'play' tonight.
