Projectors are a cool toy to show off, same for a projector as a monitor however even on lowest brightness and wattage a projector is a space heater with a quiet but still noisy fan.
The image of a $1100 short throw projector cannot even compare to a $600 75" tv from Walmart which would produce less heat and give you a far more true fake "e-ink" experience with real monochrome output.
