I have the same question. I have a brand new MBP with Thunderbolt. Work just bout me a 27' Thunderbolt display. Great so far. I also have a high-end Dell laptop. I want to connect the DVI out on the Dell base station to my Thunderbolt display. I have a mini-display port to DVI adapted. Pluged that into my MBP Thunderbolt display and got the second monitor up on from my MBP. Now when the new Thunderbolt monitor gets here, I am really hoping that I will be able to reverse the flow and connect from the DVI out of my Dell base station, to the DVI-mini-diplayport and into the back Thunderbolt port and then display the image on the Thunderbolt display.
Can anyone confirm??
Also interested in this answer, because this would mean that the monitor (screen and audio only) should be able to connect to a MiniDisplay Port MacBook Pro from 2008-2010 via
Thunderbolt Screen - MiniDisplay Port to HDMI/DVI - HDMI/DVI cable - MiniDisplayport to HDMI/DVI - MacBook Pro with MiniDisplay Port.
No love, the system requirements for the TB display clearly require a TB equipped Mac.
Thunderbolt-enabled Mac computer, including MacBook Air, MacBook Pro, Mac mini, and iMac
OS X v10.6.8 or later
Also, Apple still has the 27" Cinema Display in the product line up and at the same price.
There are a whole bunch of Thumderbolt-HDMI adapters out there. Here's one of them that actually connects to both thunderbolt and MDP: https://www.google.com/shopping/product/1493876007597784992?q=thunderbolt%20to%2 0HDMI&hl=en&prmd=imvns&bav=on.2,or.r_gc.r_pw.r_cp.r_qf.&fp=2d96ede210ccce61&bpcl =36601534&biw=1600&bih=775&tch=1&ech=1&psi=0leQUOHqG6O-yQHCxICIBw.1351636946324. 3&sa=X&ei=5VeQUL-vCIb9ygHQt4HgBA&ved=0CGEQ8wIwAA
