Why Projector lamp are expensive this is because the costs to develop and make projector lamps limits competition in the market,  so the projector bubs are costly. People often get a shock when they see price of new projector lamp, expecting it to cost similar amount to a fluorescent lamp. But, however, the technologies involved are different.

Projector lamps operate at extreme temperatures and pressures, and high-grade quartz is often used to make the bulbs to ensure resistance to these stresses is achieved whilst providing a very high-quality light output. The mercury used inside the bulb is also costly, and in addition, during the manufacture of discharge lamps the bulb may be hand-blown to ensure precision.

To get Audio from Laptop connected to projector with HDMI, you can disable the “High Definition Audio” from the “Playback devices”.

How do Projector Lamp work: They operate by sending an electrical current across pressurized ARC gap that is filled with ultra-high pressurized mercury vapor. The current lights the mercury vapor, and causes the lamp to produce an extremely bright light. The light is generated from the excitation of mercury atoms in an electrical discharge between two electrodes. This bright light is shone onto an LCD or DLP panel which in turn produces the amazing images on Screen.

Projector Lamp/ Projector Bulb is an Ultra-High Pressure Mercury Vapor ARC lamp. Projector lamps are categorized as either Metal Halide lamps or ultra-high pressure mercury vapor lamps. Philips has trademarked the name “UHP lamp” for their projector lamps.
