23" vs 24" same res, any difference in sharpness?

[Hornet]

I'm trying to decide between Samsung 2350 23" and 2450 24", both having res of 1920x1080

I'm wondering if there's a difference in the image quality between them. My main concern here is will displaying that same resolution on a larger screen area makes the image less sharp?

Other than that, the spec are pretty much the same except that the 2450 have 70000 dynamic contrast ratio as opposed to 2350's 50000

Thank you in advance for any input on this

I think you may have answered your own question. The Larger monitor had more contrast but it is a "Dynamic" ratio which is suspect. I've always thought that 23 inch displays were really 24's with too many dead pixels at the edges so they just make a fatter bezel but that's just me...

Wiki says this about it...

A notable recent development in the LCD technology is the so-called "dynamic contrast" (DC). When there is a need to display a dark image, the display would underpower the backlight lamp (or decrease the aperture of the projector's lens using an iris), but will proportionately amplify the transmission through the LCD panel. This gives the benefit of realizing the potential static contrast ratio of the LCD panel in dark scenes when the image is watched in a dark room. The drawback is that if a dark scene does contain small areas of superbright light, image quality may be over exposed.

The trick for the display is to determine how much of the highlights may be unnoticeably blown out in a given image under the given ambient lighting conditions.

Brightness, as it is most often used in marketing literature, refers to the emitted luminous intensity on screen measured in candela per square metre (cd/m2). The higher the number, the brighter the screen.

It is also common to market only the dynamic contrast ratio capability of a display (when it is better than its static contrast ratio), which should not be directly compared to the static contrast ratio. A plasma display with a static 5000:1 contrast ratio will show superior contrast to an LCD with 5000:1 dynamic and 1000:1 static contrast ratio when the input signal contains a full range of brightnesses from 0 to 100% simultaneously. They will, however, be on-par when input signal ranges only from 0 to 20% brightness.

The same resolution at a bigger size will not look quite as good. You've got the same number of pixels spread out over more area. To do that, they either need to make each pixel bigger or have more blank space between the pixels. Bigger pixels will make each pixel more evident. This is also why 720p might look ok on a 32" TV, but doesn't look nearly as good on a 50" TV.

For example, here's the 16x16 Miranda status icon that I based my avatar on.

Here's the same image resized to 32x32.

And at 64x64.

The original doesn't look too bad. But as you get bigger, you can see each pixel and it becomes blockier. Keep in mind though that this is an extreme example with a very low-res image and a major increase in size (256 pixels increased 100% and 300%). In your case, you're talking about 2,073,600 pixels and a size increase of about 2%.

While the smaller panel is technically slightly more dense with the pixels, I doubt you'll be able to tell.

If the 24" display is actually 24" (and not e.g. 23,6" like some are), then the difference in pixel size is 0.011 mm.

You can calculate it with this: http://axofiber.org.ru/inside/pixel.size.en.htm

Try calculating your current monitor's pixel size for reference so you might get a better idea.

I'm looking for buying a 23" screen with 1920x1080 (not the same one you're looking for though) and I am actually worried texts might feel too small for my taste in a longer run...
