My laser projector is crystal clear, colorful, bright and the fan never kicks on. It can do 4K/60Hz or 1080p/240Hz. Highly recommend. I have a 120" gray screen a couple meters away and I code on it all the time.

Nowadays it's even easier with the wealth of ultra short throw projectors on the market, if you have the budget. Personally I got an open-box long-throw projector for half-off at $1500, plus a $500 mid-budget screen. Definitely worth the investment.
