Not sure where to post this but I hope a guru can help me with this.
My monitor's DE15 cable is in terrible shape and can't find any replacements that actually work, I've tried multiple cheap and expensive cables and some have terrible interference, others have no interference but only work when the resolution is 640x480 and others don't work at all.
It's a Viewsonic G225FB+ by the way, old school but experienced users must know it's a reliable one, I've got it for cents from a closing store a few years ago and fell in love with it. I know the monitor was originally shipped with a DB15 to 5BNC cable for Macs and also an adapter from DB15 to DE15 because it says so in the box but I don't have them, only the DE15 cable.
Thing is, there's also a 5BNC input available -I don't know if that even works as I've never used it, it should though- so I had the idea of converting HDMI to analog DVI first -my graphics card has no analog outputs- and then making my own cable to connect the monitor and converter.
I've looked up pinouts and found this for analog DVI and this came up.
(resized for convenience)
I can see RGB, H/VSYNC and GND at the left which would be the ones the 5BNC input requires, yet in the first picture it states more pins are required for an analog connector including data, clock, hot plug detect and a 5V line "power for monitor when in standby". Are those actually needed? Isn't the monitor self powered when in standby or is that pin simply for the graphics card to send the monitor a "go standby now instead of displaying a black screen" signal?
The only data I could find regarding to the BNC input is the following:
RGB Analog (0.7/1.0 Vp-p, 75 Ohms)
H: 30-130 kHz
V: 50-160 Hz
H/V Separated (TTL), Composite, Sync on Green (SOG).
That'd be enough to run it at native res of 2048x1536@85Hz I suppose. I know DVI-A only supports up to 60Hz in the books but technically I'd only be using the cable to adapt a physical interface while the converter does the rest of the job.
