76997 2002-09-06 06:16:00 I'm searching for a driver (well a .inf actually) for a DEC VRC15-K4 15" monitor. I search www.driverguide.com and came up with nothing, and DEC doesn't exist anymore, so I can't go searching there. Any ideas? Or does anyone actually have one? (yeah right!) :D

76998 2002-09-06 06:24:00 It's a monitor which was used with Alpha Stations. About all I can find in a quick look is that it is SVGA NI. So a standard SVGA driver should do it.

Google finds a lot of people who want to sell them ... at avrious prices. It's also listed in a Compaq page of Alpha options.

76999 2002-09-06 08:14:00 You actually found mention of them? I did a search (admittedly on AltaVista rather than Google) and it didn't find anything. I did an FCC search and it told me that it was a Sampo, and Sampo don't have any old drivers on their site. I don't know what model Sampo it is either.
I have it running fine, but am desiring to do some "testing" on it, so want to use the specific driver, which admittedly I used to have, but happened to "lose" it when I formatted my computer about a year ago :8}.

Since you seem to know a little ;) can you tell me what the small plug (slightly smaller than a cdrom audio plug that plugs into your sound card) is that's just next to the VGA input plug on the back of the monitor?

77000 2002-09-06 09:06:00 I came up with this specification:
VRC15-K4 15"(13.9"VIEWABLE IMAGE SIZE) HIGH-RESOLUTION COLOR MONITOR FLAT SQUARE INVAR CRT, 0.28MM DOT PITCH, VGA TO 1024X768 @75HZ, MPRII, ENERGY STAR, HD15 MALE TO MALE VIDEO CABLE, SOUTHERN HEMISPHERE OPERATION, LIGHT GRAY ENCLOSURE

from this site (www.compaq.com)

Havent found a driver yet though. If the monitor has digital controls, it's just possible that the connector at the back next to the VGA socket is for plugging in a "black box" to adjust some settings digitally that cant be set manually via the buttons.
One of the Compaq monitors had this feature for adjusting pin-cushion, there being no internal trim pot, or user control, the model FS150 I think from memory.

77001 2002-09-06 09:33:00 Wow where are you finding all this stuff? My searches came up blank. Maybe I should start using Google :)

Sounds like that's what the plug probably does - I didn't think it could have been used for actual picture, so it'd have had to have been some kind of control thing

77002 2002-09-07 03:58:00 My search on google was for "vrc15". It's odd that Alta Vista didn't find anything: that search engine was a Digital ("DEC" -- Digital Equipment Corporation) product. Google is brilliant.

I sort of know DEC type device names, but never worked with anything "that" modern. I have managed to connect a 5.25" floppy to my microVax, though.

77003 2002-09-07 08:08:00 If only a more complete spec for the monitor could be found including horizontal frequency, ICMProfile and whether DPMS is supported then it would be easy to write your own driver file .
Here is one based on some guesswork of specs, copy and paste to a text editor and call it DEC . inf Put it in c:\windows\inf
Inf is a hidden file . When you call up a list of hardware in the change monitor settings, DEC will appear .

77004 2002-09-07 10:00:00 Hey well that might work :) I never thought about writing my own if I could find specs... maybe I should start doing that - give me something new to learn.

<copies and pastes> I'll see if this works :)

77005 2002-09-07 10:05:00 hmmm... Win XP didn't really like that, although it didn't make the screen not work :)

77006 2002-09-07 10:51:00 Oh, Win XP? Maybe that has a different format, I'll try and find out. MS should have some info on .inf files.
I tried it with Win98SE and my monitor which has a higher spec, and it was ok.
Really all these inf files do is to specify the frequencies and max resolution so that they are not exceeded.
Thats why a MS generic driver is usually ok.

You could try lowering the ICMProfile to 7 instead of 9.
HKR.. ICMProfile,1,7
But I havent found out yet what those parameters actually do, except associated somehow with colour.
