Hi Guys!
I'm posting this thread in hopes of solving, for me and possibly for other forum members, what has become a serious concern:
How to keep from frying my CRT projector by throwing too much at it?
While it might not be directly related to running his projector at too high a refresh rate, Paul had a problem with his projector which is described here:
http://www.avsforum.com/avs-vb/showt...threadid=89786
Paul's plight brought to my attention what could be an important issue for anyone who has invested both time and money into a home theater CRT: preserving the lifespan of his/her projector and still getting the best possible performance out of it.
I previously experimented with relatively high scan rates, but the resolutions were "card limited" due to the GeForceII 3Mb MX graphics card I was using, which didn't output at the same time the highest resolutions at the highest refresh rates that my projector's specs would apparently handle. Now it is a different story because with a Radeon 64DDR, Powerstrip will allow me to define without any fuss resolutions and refresh rates both in excess of my projector's capabilities.
To make my question simple, here goes:
- the Sony VPH-1292Q can accept 2000x1600 lines
- it is rated for 135kHz and 150Hz with a 120MHz bandwith
So my foolhardy questions are:
1. Can it run at 2000x1600 at 150Hz? (max of all specs at once)
2. As most likely not, what formula is used to calculate the maximum refresh rate at each given resolution?
3. Does one have to factor in the combined frequencies of vertical and horizontal rates in the calculation, or are they determined independently of one another?
Apologies if my ignorance of the technical aspects of these parameters and their interactions shocks the CRT geniuses present - just trying to become a power user without blowing up the machine in the process.
Thanks in advance for your helpful advice.
Cheers,
