Video and data projection
too bright to read clearly on Sony VPL-SC50/XC50/SC60 projector
your data projection using your Sony VPL-SC50 or VPL-XC50 is much
too bright or intense to read clearly, please read on before you
try adjusting the brightness and contrast! If you already tried
the brightness and contrast, don't worry, you will just have to
adjust them again once you have properly solved the problem.
There is a poorly documented and poorly located (in our opinion)
switch on the bottom of these Sony projectors. The switch is marked
75ohm, ON/OFF, and is located just below the serial number plate.
Make sure this switch is in the "ON" position.
is a termination switch for the 15-pin RGB input. We feel this
is a poor location for the switch since it should be near the
connector it controls, plus it can inadvertently be switched into
the wrong position by sliding the projector across some types
this switch is in the "OFF" position, the input isn't
terminated. An un-terminated input will result in a higher level
signal than is correct and the overdriven circuitry will cause
your display to be too intensely bright. Now, normally in projection,
bright is good, but this will be so bright it will cause colors
and letters to bleed together and become unreadable.
you are even able to locate this switch in the operating instructions
for the projector, you will discover a poorly worded description
that tells you "Normally set to ON. Set it to OFF when the
projector is connected to a computer or monitor." We have
to assume this confusing phrase is the result of an incorrect
translation from Japanese to English. This incorrectly tells you
to put the switch to OFF when using a computer. Don't believe
