I think I may be in the same boat. I am not sure whether the PJ will have enough res to allow me to do my work. I am sure there must be a switchbox which will allow you to use 2 monitors for 1 pc... I know that there is a switch box to allow 2 computers to share a single monitor, maybe that might work
Hi, a switch box is one answer or alternatively put the money towards a dual head graphics card. If your graphics needs are modest then a Radeon 9000 dual head is around £50 and runs a projector and separate monitor no problem even at different resolutions if needed.
Dual head can be a bit tricky since you normally need a primary display and secondary running at the same time so that you know where your mouse is. The secondary usually has only basic features ie. crappy 3D, etc...
Yes, it can be a bit naff. I bought a dual head Radeon 7000 for this very reason, but the video overlay only works on the primary screen, so you end up having the main screen up on the PJ anyway. I've found I only use a monitor for tinkering sessions, so I do swap it with the PJ connection when I need it - other times it gets moved out of the way to keep the WAF up.
