Not if the image is outputted at 1280x1024.
If you get a 1280x960 image and stretch it to fill the screen then it will obviously be distorted, but most things have the option for 1280x1024 which means images are correctly rendered.

Please explain in more detail.
Say you are playing a game. If the person who drew the image when creating the game meant to show a 4:3 aspect ratio, then the only way to show it with the correct aspect ratio on a screen with a 5:4 aspect ratio is to omit some portion of the image from the left or right, or to show black borders at the top and bottom. Or, if it shows everything that was in the original image, the aspect ratio will be wrong (circles will turn into ovals). Is that not right?

Yep. A 19" LCD has a 5:4 aspect ratio compared to 19" CRT with a 4:3 aspect ratio. A circle will look normal.
Most games written within the last decade or so support (at least somewhat) variable aspect ratios, and can render on demand to both 4:3 and 5:4 screens properly. Most recent games can also handle other ARs, like 16:9 and 16:10.
If you try to use a 4:3 resolution on a 5:4 display (or vice versa), obviously it will be distorted (or else not fill up the whole screen).
If the programmer used 'vectors', as they do, then a circle will be a circle on any computer, almost.

The image will be distorted if you have the monitor scale to a 4:3 screen resolution. Turning scaling off will produce black bars. That's why it's always best to play at the native screen res on a LCD.
Let me ask the question in a different way.
Is it possible to see the image on a 19" LCD and see all of it and have no black bars on the sides or the top or bottom and have no distortion (circles look like exact circles)?

It depends on the lcd. But typically as long as your running at the native res of the lcd then everything should be perfect. A square will be a square a circle will be a circle.
I'll use my monitor as an example since I know it off hand and it's really easy. It's a dell 2001 it's 16inchs wide and 12 inches tall lcd and runs at 1600x1200 resolution. Obviously at the native resolution everything is going to be perfectly square because it's 100 pixels per inch. Actually better than a monitor because there's no adjustments needed to set it correctly.
If your running at a different resolution and it's having to scale it up then it's possible things will look off.
The other possiblity was some older cheaper lcd weren't square so to speak. Thier pixel dimension didn't match thier physical dimensions. IE at 1600x1200 resolution but a panel that 16 inch by 10 inch. On that type of lcd things are pretty much never going to look right but you don't see that anymore even on cheap monitors.

Not outside its native screen resolution. But if you game a lot and play at a resolution at 1024x768 the distortion isn't really that noticeable if have it scale to full panel size.
I'm sorry but your monitor does not meet my concern! I was asking about a monitor whose native resolution was 1280x1024 (5x4 not 4x3 like yours).

Not if it's a premade video, but games simply render what is 'onscreen' out of a mappe physical world. If the 'onscreen portion' is 5:4, that's what will be rendered by the video card, and displayed on screen. I would guess this usually means showing more top and bottom rather than showing less side to side.
If you are running at a resolution that has the same AR as the display, yes. If not, no. This is true for ANY display ANY time the source and display do not have the same AR.
Almost every 3D game on the market can run at 1280x1024, except for some very old games that run at fixed resolutions.
Are you certain about that? A few things about 1280 X 1024 I never understood.
1) Why did move to a 5:4 aspect in the first place? 4:3 was already established.
2) Do programs really run 5:4 when that resolution is selected? Or is it perhaps so similar that no one really notices that it is slightly off? The difference is greater from 16:9 to 4:3 than 5:4 to 4:3.
I am not doubting you, but the difference between 5:4 and 4:3 is quite small as opposed to 16:9 to 4:3.
If you keep the 19" LCD at 1280x1024 you will not have any problems
I have a 19" Dell 1900FP next to my 18" Samsung 997DF CRT both running 1280x1024. A circle looks the same on each screen, the only difference is the circle is bigger on the 19".
If i am not mistaken CRT and LCDs are measured diag. so you should get just a circled scaled up or down depending what your reference was.
If you try to run 1280x960 on a native 1280x1024 scrren, it will either do one of the following:
1) display black bars where the missing 64 horzontial lines are suppose to be (this is good as you still get a circle, just less of view.
2) Scale the pixels so they use more than one pixel per dot vertically. So your circle will be scale on the y axis and not on the x, now you have an ellipse, so do not do this lol.
i hope this helps.

i have a question. my laptop plays unreal tournament a 1024x 768 and everything looks fine. then at 1280x800, the circles become ovals...is it just the game?
umm, no those are different aspect ratios
12x8 is 16:10 and 10x7 is 4:3. so you have to turn off scaling
BTW whats your native res?

For gaming not always. For F.E.A.R. I ran it at 1024x768 and it looked and played really nice. The distortion (if you let it scale) is so minimal that I doubt many people will notice it in GAMES. If you are worried about it than spend a little more money and get a 20" LCD.

No reason to get pissy here as he was just giving an exaple which you clearly missunderstood as he wasn't talking about 4:3 display but rather 16:10 one with non-squre pixels.
But as to your question, you have to be more specific. A circle on a webpage? Yeah, that will be round in just about any browser. A circle in a movie? That would depend on the program you use to view the movie in and unfortunatly many don't set the aspect ratio right for non-4:3 displays. A circle in a game? That just comes down to how the game works, some will set the aspect ratio proper for everything, some will squash the HUD but render the game right, and some squash everything.
So yeah, it isn't always going to be perfect, but for the most part you will be able to go without any aspect ratio issues. At worst, you'll just want to run 1280x960 with the tiny bit of letterboxing that comes with that for the few programs that don't work with 5:4 aspect ratios to your liking; but that should be rather rare. I use a 16:9 display which has far less support than a 5:4 display like you are considering and for the most part the stuff I use runs fullscreen on my display just fine.

I'd bet money that native res is 1200x800. Assuming that, obviously the reason he would say circles become ovals is becuase the game stretchs the HUD or maybe even the whole game at 1280x800, while 1024x768 runs in proper 4:3 pillarboxed on his display.
I was not getting ***** at all. I tried to explain that my concern was about the aspect ratio of the screen, which for the example he mentioned I thought did not stand since his example had the same aspect ratio as the standard 4:3. I am thankful to anyone who has contributed to this thread helping me to understand. I would not be surprised if I misunderstood something. I asked the question, right? That means to begin with, I accepted that I did not know something.
I am considering getting a 19" monitor. I intend to run everything at the native resolution. Since the aspect ratio of the 19" LCD screen (5:4) is different from the standard (4:3), I was asking if this could cause any problems (whether one can notice it or not easily) for anything. I have to spend money and want to know all the limitations before I do that. I am not trying to have a troll war here.
I was referring to this, which I did not have access to at the time of posting so I did not include it.
I'm not sure which thing you're questioning, but yes, I'm sure about what I posted.
If the AR of the image does not match the AR of the display, it will either be distorted (or partially cut off, as when 16:9 movies are pan-and-scanned to 4:3), or will not fill the entire screen.
I'm not really sure myself. You do get more surface area for a given diagonal at 5:4 (you'd get even more at a 1:1 AR), and maybe there were manufacturing-related reasons for it to be adopted as a standard LCD resolution (like maybe it makes the panels tile better for a given size glass substrate).
Yes, they really run 5:4 (at least, most of them do; it is up to the game engine to support the current aspect ratio). You can *clearly* tell the difference between 4:3 and 5:4; just try running 1024x768 on a 1280x1024 LCD, or running 1280x1024 on a 4:3 CRT and stretching it so it fills the whole screen. The vertical distortion is readily apparent.

If that is the case then, I can't imagine it would be any more work for a dev to include widescreen support. If you are already have an engine than can handle different aspect ratios, then adding 16:9 or 16:10 support should be quite simple, which gives the devs no excuse in my opinion. I have never been a fan of 5:4 to be honest.
