Okey how big LCD TV you are talking about. Let me tell you what i did. I bought Toshiba projector which cost me like around $800 and 84" pull down screen like $200. I think this is much cheaper than the big LCD TV and all the hassle you will go while shipping it. On top of it since these items are considered as accessories for your laptop i was able to pass through custom without paying a penny. Isn't it cool deal. Well what worked for me doesn't meant it may worked with you too. At last aafno aafno choice ho.

P.S. U can even be more cheaper instead of buying screen here u can build white plywood board just like in your office and use it as screen.
