I've looked at an LCD table for the last couple of years, I've hit the following issues:
- Cost
- Resolution vs. Size
- View Angle
- Heat
I wanted to try it with my two 30" 2560x1600 HPs, but each generates a scarry amount of heat (draws ~175W when in operation). Those are also my main displays and not exactly cheap. So I looked at an affordable 4 monitor setup with a high resolution and small bevels, you could get some interesting monitors for decent prices, but all had the crappy TN displays (doable when setup in front of you, not when laying down). Some of the older refurbished models were decently priced, but again you had a lot of power usage and thus heat. For now I've scrapped the idea for now, I might revisit it in the future (tech always advances).
