Projector replacement

Hello!

I have an A320 cockpit and for a long time have been using two different projectors connected via the DualHead2Go. (resolution 2048x786 because of FSX - native: each 800x600)
The problem always has been the edge in the middle of the projection. The colours are not same, too - the right side projector has a light yellowness.
Now I am thinking about the option of buying a short distance 720p projector and replacing the two old ones.
My aims: To get rid of the edge in the middle and having a better screen resolution (via HDMI).
What do you think? Is this worth buying for?

Many thanks in advance for your help,
Christoph
