Thanks for that: since I will still have to control the Mac display by keyboard or mouse while photos etc are dispayed on the Sony TV, will I need to get a 2-way HDMI adaptor for the Dell monitor?
My MacPro is a quad-core Intel Xeon 2.66 GHz bought in 2007. This uses Xeon 5100 processors and DDR 5100 667MHz memory.
It would certainly be v. helpful if you can advise me on the exact adapter to get.
Many thanks – John
V. helpful reply – now just need to find a UK source for the adapter and discover if my PCI card has 2 output sockets.
