Electrohome ECP 4501
Video Projector
This is one of the finest video
projectors available. This
is a professional CRT projector. It has far better performance than LCD or DLP
projectors. It is amazingly bright, and is ideal for home theater or graphics
projection. It is fully HDTV compatible and accepts multiple aspect ratios.
Our unit was produced in 1996 and is
tested and functional. The ACOM worked perfectly, and the projector
produced a bright crisp image.
The ACOM automatically sets the
convergence eliminating time consuming manual setup and touch-up. Believe
me you will really appreciate this feature when you don’t have to climb the
ladder to adjust the convergence on your projector.
It is good cosmetic condition, and
includes both the wired and wireless remote controls. This unit is being sold as
is, so please bid accordingly.
This unit is very large and heavy, over
100 pounds. The buyer pays for all shipping expenses, which may be significant.
No exceptions.
