This shows the problem that you will encounter with this kind of conversion. (uses a USB connection to supply power to the adapter)Īre you certain that you only have a DVI video output on the PC? Are there ANY other choices? Is there HDMI, for example? There's more choices then. It is more than a simple adapter, requires connection to power, and is more expensive. However, Winston- in post above suggested an active adapter, which SHOULD work.
As I understand it, DVI does NOT transmit DisplayPort - so the simple adapter that you linked would not do the job you want (which is transmit a displayport signal to the external iMac) That being my opinion, I could be wrong, as there seem to be a number of sites that suggest that it can work, as long as you have a DisplayPort signal to use. You need a native output with mDP hardware. I am pretty sure that won't work with a DVI to mini DisplayPort adapter. Your 2010 27-inch iMac can use Target Display mode with a mini DisplayPort to mini DisplayPort cable.Īnd, you need a Mac with a native Mini DisplayPort output. I have tried switching HDMI cables, also, to no avail.You need two things to connect to an iMac that has Target Display mode: I should note that when it is working, it seems to be shoddy, with audio blips and visual distortion sometimes. I know it has succeeded because I see the displays icon in the toolbar and I am able to choose display mirroring, etc. Basically if the computer has been on for a while I have no chance of getting it to work, but after resetting and whatnot it finally will work seemingly by chance after a handful of tries. I have tried resetting my PRAM and it seems to allow me to get it to work after unplugging and replugging like 3 or 4 times. I plug it into the computer and the screen turns blue as if it has detected the TV, yet when it comes back to normal, nothing happens either on the TV or the Macbook.
I recently purchased a Mini DisplayPort to HDMI (with audio) adapter from Monoprice for my mid-2010 Macbook Pro and I am having issues.īasically everything was working fine a month or two ago but just recently I have been having problems getting my Macbook to detect the HD TV.
