Pixel doubling on 31khz monitors with custom drivers?
lettuce:
So in theory would this work for LCD screens??
So what setting would i need to add in for my Pentranic 29" Multi-sync monitor?? These are the only spec i could find in the pdf manual...
Or though it states 800x600 it actually does 1024x768
newmanfamilyvlogs:
So it will sync on 15-40kHz without any switches/jumpers on the board?
I'm gonna take a stab at suggesting this:
--- Quote ---monitor_specs_0 = "15000-40000, 47.00-90.00, 0.600, 2.500, 2.800, 0.032, 0.096, 0.448, 0, 0, 640, 768"
--- End quote ---
bitbytebit or calamity are going to have to weigh in on it though.. I'm not sure what would be appropriate for the various porch values.
Edit: Based on calamity's suggestion that these monitors are sensitive to wrong ranges, please don't use the above values until the porches can be verified.

But that's a CRT monitor isn't it?
I've read that Pentranic monitors are delicate and may even break with the wrong settings, so please BE CAREFUL. However, you shouldn't have problems if you respect the values in that chart. For the porch values, if that monitor has a decent EDID, you can use the MonInfo program (http://www.entechtaiwan.com/util/moninfo.shtm) to read EDID's info, you will retrieve one or more modelines written in its EDID, which your monitor will be confortable with. We can then use those values to cook a monitor_specs line that fits your monitor.

Hi, yeah it is a CTR monitor, i know the Pentranic monitor isnt the greatest, but was really the only option i had here in the UK...unless i wanted to pay over the odds for overseas shipping :(. Ok downloaded the moninfo prog you suggested. Not sure how to use it correctly just loaded the prog and said it was anaylsing. Heres the info it came back with (sorry about the length)

Calamity:
That log seems to come from an Acer 20" monitor, not from the Pentranic. Try to get the right one with your Pentranic monitor attached, notice the MonInfo program has a list on the left for available plug and play displays.
Don't get me wrong, I wish I had a multisync monitor around, it's only that I read a story of a Pentranic monitor broken for setting it to 1024x768, maybe a different model:
