Okay so I've had my 4850 running dual monitors since Lion GM days but oddly enough I can't any signal working when using two digital outputs (digita outputs being dvi and hdmi) but dual monitors works fine when using one digital (either hdmi or dvi) and the analog (the vga port). (On 10.7.2 currently) Just curious if anyone has dual digital output from their 4850. My 4850 is this variant

All outputs work when used by itself for a single monitor use but the dual monitors using only digital outputs causes a weird screen flicker. I'm currently using the default redeon framebuffer because other frame buffers seem to have my card running at fufll speed (this is found out because I notice a significant bump in temps in iStats).

Signals output for 22" 1080p monitor (via dvi or hdmi doesn't matter) and a 19" monitor (via vga)

Signal output for 22" 1080p (using vga) and 50" LG tv (via hdmi)

Just want to know if anyone has signal out via 2 x dvi or hdmi & dvi or if there's a possible way via a dsdt edit that it could be possible to use both digital outputs simultaneously.

Any input would be greatly appreciated =D
