Will I be able to run my 21.5" iMac as a monitor using the Thunderbolt cable" I don't want a 27" monitor.

I have been able to do this in my testing previously, as long as you have an iMac that supports this.

As long as your iMac will support being a host monitor yes it will work just fine.

YUP, you just need to remove the normal iMac stand and get the VESA mount kit from Apple. It's like $100. I actually have my Thunderbolt display on it.

I think it should, both are 1333MHz. They have been working great for over a year in my 13" MBP 2011. Here is an install guide: for the 27" http://www.ifixit.com/Guide/iMac+Intel+27-Inch+EMC+2429+RAM+Replacement/7570 for the 21": http://www.ifixit.com/Guide/iMac+Intel+21.5-Inch+EMC+2428+RAM+Replacement/5660

First off - I would recommend getting a better Asus monitor like the 246 or 248 - the one with LED. I sold this one already. Answer to your question is yes. You can connect macbooks to any monitory but you need the display port converter (for hdmi/dvi). As for mac tower, if they take display port, it should not be a problem. Check at the apple store.

Yes. Many people in my office have been using this with both a laptop and a 24" monitor so a 27" iMac safely.

The laptop should be ok for a while, since if it draws too much it can draw the rest of the power from it's internal battery. You would have to look at the power requirements for your iMac to see whether a little under 300 watts will be enough to power it, but my guess would be that with the 27" screen there won't be enough power.

No. According to Apple, the post-2011 iMac supports only *other Macs* using *Thunderbolt* cables.

It should work. Simply launch your older iMac in target display mode while it is connected with this cable. I did this with my Laptop and the same year iMac before purchasing a thunderbolt display.

Although I have no idea how heavy your 21.5 is, I have a 2011 iMac 27 and I'm certain this arm cannot hold it up. In the short term "maybe" it could, but I wouldn't trust it to carry the load over the long term. Additionally, I don't see how this arm could interface with the back of the iMac, which is designed to stand on it's own mount precisely because it is a bit on the heavy side, as well a bit off balance without the stand attached. I'm sorry I can't be more helpful. MIKE

Yes, I use this display at full resolution with my MacBooks. I'm using this cable: "Cable Matters Gold Plated Mini DisplayPort (Thunderbolt™ Port Compatible) to DisplayPort Cable" for my Macs, and this cable "Cables To Go 26911 DVI-D Male/Male Dual Link Digital Video Cable" for my Windows workstation.

Yes, but I'm waiting for Apple to upgrade this monitor to the new flat one like in the iMac - and, perhaps Retina. Don't know why they don't do that. Probably don't sell enough of them "stand-alone" like they do the iMac. I had this one at work and it's very nice. Display is just remarkable - even non-Retina. Considering how much time you spend looking at a monitor - do your eyes a favor and get the best!

The thunderbolt cable only works with the Apple thunderbolt monitor. You can get a thunderbolt adapter that will change it to DVI/VGA/HDMI fairly cheap

I have a 27" iMac on the stand and I have noticed that it has "swayed" about 3/16" in the center. If you plan on two 24" monitors, they will probably be set close to the sides instead of in the middle which should be ok.

I have a 2011 27" iMac and it has 2 thunderbolt 10 gb connectors on the back of it. Purchase a thunderbolt cable and you will have a far better experience than using one of the usb 2 ports.

I would suggest looking at the back of the iMac, if it has a VESA mount or if you see 4 mounting points within 4 inches of each other and the center of the back of the monitor, then it should be possible. If you do not have the VESA mount, then it probably would not work for you.

You should be able to hook into whatever monitor you have so long as you have the correct cable and adapter. THere are a variety of adapters that can fit into the Thunderbolt port which supports video

From the reviews I've read - yes. However I've had no experience in that arena since I am iMac based. Sorry I can't be of more help.
