@thx, can't help much .. but I believe you can diagnose further your problem .. Do you see the BIOS bootup screen on both monitors? Try disconnecting the two monitors and let only one monitor connected to the graphics card (the port that aren't recognised). Swap around with the other monitor and vice versa .. if both monitors and ports are okay, then I believe you need to go ahead with diagnosing the Lion problem .. or better still, are both monitors working okay on Windows?
Hi,
I have both win7 and lion ..
in win7 .. both monitors OK ...
what happen when i was using 10.7 .. during bootup, only one screen will show the process etc .. but when ready, both screen will display ..
i tried to power off that one monitor, leaving 2nd monitor (connected using displayport at my GC) .. nothing came oout ..
it happen when me upgrade to 10.7.2 .. using multibeast 4.0.2 ...
i suppose to click only audio part and migration extension .. but i selected eastbeast option also which i believe overide my previous setting ..
manage to recover my audio .. but not for dual view ..
