Hey guys I just wanted to share my solution for a credible - yet relatively low cost set up.
It consists of 2-32" LED TVs for forward view, 2-24" LCDs for the panel and a 19" LCD for the GPS (5 screens in total running in ATI eyefinity).
This setup was a lot of fun to fly by itself, the huge improvement came however once I had the idea to apply a corrugated plastic printed panel - with a real cockpit photo over the whole thing. The difference and immersion is enormous, as the upper panel extends beyond your field of view, when you look forward you feel you're really inside a cockpit . I am installing switches and LED lights a bit at a time to make it look even more realistic. The width is 90% of the real thing (747-400).
I will post more pics as I get the time.
