Atlona DP-200 DOES NOT WORK with 27" iMac
I recently purchased the DP-200 from Atlona
http://www.atlona.com/Atlona-DVI-to-Mini-DisplayPort-Converter-p-17859.html for the purpose of using my 27" iMac in target display mode with my DVI equipped Mac Mini. After correctly hooking everything up I was frustrated to see that all I could get was a black screen on the iMac with would then revert back to the normal iMac display after a few seconds.
After calling Atlona tech support this morning I've learned that in fact the AT-DP200 DOES NOT WORK with the 27" iMac. Since I purchased the device Atlona has added this note to their product page:
"Note for iMac 27" users only: Even our box is capable of passing high resolutions up to 1920x1200, users of iMac 27" will only be able to get picture with resolutions up to 1280x720 (720P). The reason for it is that iMac 27" native resolutions are: 800x600, 1280x720 or 2560x1440 (since our box is limited to single link (1920x1200), and can't work with 2560x1440 it will take the next resolution down the list which is 720p. We are working on AT-DP400 which will allow dual link resolutions (such as 2560x1440) to pass though. For PS3 or Xbox users, you can use our converter without additional devices at only 720p resolution. Make sure to set 720p prior connecting it to the DP200."
Although this suggests the device will work at a resolution of 1280x720, Atlona tech support says it will not do so without a firmware update for the DP-200 which only they can perform in-house.
I was instructed to email their RMA department which I've done and am awaiting a reply from them as to my options. I can post the results of that communication if anyone is interested.
