I have a 24" monitor on 1920x1080 DVI, and I am considering to get a second one.

Then you're lucky, because all TVs I've used with hdmi have overscan,... usually about 40+ pixels top/bottom & 25 or so right/left.

If you have a TV with DVI,... sure. But I've never seen one in any store I've been in (granted, I don't even look at models that cost over $800). A true monitor is different, obviously,... But we were talking about TVs... All TVs I've seen have 1-4 HDMI connectors and maybe one VGA, if you're lucky. Manufacturers are moving away from VGA or DVI, because there's no DRM on either standard.

Anything under 40" is usually 1366x768 natural resolution (or less). HDMI might support a "virtual" 1080p, but it's dithered... At 40"+, it's hit and miss whether its 1080p or not. I've seen articles where people got burned,... finding out that their TV is really only 1366x768 natural resolution, when it said "HD." Problem is there is little in way of consumer regulation which defines "HD" (in the US, anyway).

omg!!!!

24" is fine so is 42", 19" It's really a matter of preference.
Somebody mark this solved!!

19" 1280x1024. Will have a second one as well as soon as I am able to convince my boss it's necessary :-)

Once you go big, trust me my friend, you will never go back.
I used to have a 15", upgraded to a 19" and wow it was awesome.
Of late i upgraded to an HD 23" Samsung & God, it feels like am in heaven-its great for anything.
So big is beautiful.

I don't watch movies or play games, but having multiple apps (usually terminals) open next to each other instead of on top if each other is soooo sweet.

Is 27" too big?

Back in my days with TVs, there was a set of guidelines about tv size. From a customer's address, we would have an idea of the room size, and could recommend a screen size accordingly. This acknowledged the viewer's maximum comfortable angle of vision. Acknowledge yours, and purchase as much as you are comfortable with.

If you will be recreating 'the back row of the movies' on your sofa, you can use a bigger screen than if you are going to be up in front of it always. 24" is a safe maximum.

iMac is 27".
I want to have such a big monitor. :D

You need to consider a few things,...
* Length of time you'll be at the monitor (longer = more eye strain)
* Size vs. location (how much of your visual field does it occupy, and whether you can work like that)
* Resolution & dot pitch (ideal = you see no pixels just the image they produce)
* What the interface is (VGA, DVI, HDMI, Display Port,... Overscan?! Underscan?!)
* What the graphics chipset can handle (resolutions, and outputs)

Put a big monitor too close, and you better be taking frequent breaks. Stare at it too long and you can get eye strain, especially without anything else in your visual field, or somewhere else you can glance.

It also depends on the work you'll be doing on it,... coding/reading, gaming, watching movies, etc.

When I have to detail work (configuration, etc.) on my HTPCs, I have to stand closer, sometime for protracted periods, leading to neck strain,...

So,... judge your situation accordingly.

why iMac comes with only 1 option, 27" monitor,
will it spoil your eyes?

How close you sittin'?
