Hi
I'm new here.
I just registered because I need to find a projector that can sync on a 22.15kHz signal (Hsync) over composite. I contacted NEC's technical support but they are unable to answer this question and I don't blame them at all, their representative was very competent and that question is kinda odd.
Basically, I'd like to hack an old computer of mine and here are the specs of whatever it'll be outputting on composite.
HSYNC-Frequency
22.25kHz, 45µs period, 18.45µs low
59% PWM duty cycle
VSYNC-Frequency (Refresh rate)
60.15Hz, 16700µs period, 180µs low
99% PWM duty cycle
Any help appreciated!
Thanks,
BGE
