[edit] Cable Info

How long can a VGA cable be? AndrewRH 19:31, 3 May 2007 (UTC)

As long as a piece of string ;) . Depends on the signal - according to http://www.scala.com/hardware/dvi-vga-cable.html - 10 meters for 1024 x 768 or better, if you using 640 x 480 - probably as much as 100 meters. Megapixie 03:13, 4 May 2007 (UTC)
The characteristics of the particular devices at both ends of the cable are likely to have some effect on the maximum usable length, as will the thickness of the wire and possibly how the ground conductors in the cable are configured, in addition to the resolution being a factor. Furthermore, there's going to be a range of the cable working well, then working poorly, then not working as you extend it. JNW2 (talk) 08:13, 1 January 2008 (UTC)

[edit] Signal Specification

Does anybody know the signal specification? It would be great if we could add a section like the one in Enhanced Graphics Adapter. — Mobius 22:19, 2 June 2006 (UTC)

There is no signal specification because unlike the EGA, the VGA connector is used by many different graphics cards besides the original VGA. Refer to the sentence in the VGA article itself:
It may also refer to the 15-pin D-subminiature VGA connector which is still widely used to carry analog video signals of all resolutions. (emphasis added by me)

Where might I find more information on the various types of signals used? 209.42.59.161 15:37, 1 November 2006 (UTC)

if pin 11 is snapped off the plug that goes from the monitor to the computer, is there any reason why it shouldnt work??? ive tried to read info on the pin config but i dont understand. some say GND, some say ID_1... it was working for ages without it, but suddenly everything looks purple... —Preceding unsigned comment added by 210.87.18.76 (talk • contribs)

Could be a problem with the display or the graphics card - is it a CRT ? Wouldn't be unheard of for the green gun to go bad - do the on screen displays look purple too ? or do they comeout okay Megapixie 06:53, 30 October 2006 (UTC)

[edit] Is VGA Hot Swap-able?

Is VGA -- officially, in practice without risk, in practice with risk -- hot swap-able? —Preceding unsigned comment added by 75.6.238.37 (talk • contribs)

I don't know the official answer. I do know that the DDC protocol supports it (the monitor grounds a pin so the card knows if it is present and will reinitialize) but electrically I am not sure if surge suppression is required. I do know that the card I worked on showed suppression diodes external to the VGA chip on the chip's datasheet so it is definitely recommended. And I know I've personally yanked out the cable at least a few hundred times in my lifetime. :) — RevRagnarok Talk Contrib 14:52, 4 November 2006 (UTC)

[edit] Connecting Computer to LCD TV

Both have female connectors. To make a lead is it a simple case of getting two male connectors and matching up the pins(name to name), are all fifteen required ? -Teeteetee 20:18, 17 March 2007 (UTC)

[edit] VGA-9 to VGA DB15

Can any one tell me if is it possible to adapt a modern monitor (VGA DB15 conector) to operate from an older computer using a VGA-9 connector, older computer is controler for CNC machine. OEM no longer in business updating computer not an option.--24.36.23.59 05:49, 27 April 2007 (UTC)

Are you sure it's even VGA? I thought 9 pin was only CGA or EGA. — RevRagnarok Talk Contrib 10:47, 27 April 2007 (UTC)
It may not be either, as 9-pin connectors were used for some of the old Atari-era multisync monitors (TV resolution); it may be that hooking it up to a SCART socket would work (with an appropriate TV set, obviously). If that's the case you'd need an upscan converter to run it with a standard VGA monitor (a device that converts TV-standard signals into VGA-compatible ones); having a quick Google for that will find you plenty of options.

The original monitor on this system was from a Commador? 64 with an 8pin DIN connector, the replacement is an old Tandy (RadioShack) multisync monitor, 9pin DBI. I will try the upscan converter, thanks for the info, David

[edit] Naming Semantics

I added a [citation needed] to the section which mentions that the connector is "is almost universally called 'HD-15'" as this is an obvious statement of opinion, and my vga extension cable packaging begs to differ... I've "almost universally" (what does that even mean?) heard it referred to as a DB-15 connector. 24.68.135.133 03:47, 30 June 2007 (UTC)

please tell me if you got any solution....i have IBM lenovo t60p —Preceding unsigned comment added by 122.169.131.81 (talk) 09:47, 7 October 2007 (UTC)

You'll need to buy a converter. -- Beland (talk) 22:22, 18 December 2007 (UTC)

[edit] Pin 9

 Please help improve this article or section by expanding it.
Further information might be found on the talk page or at requests for expansion. (December 2007)

I have seem some cables advertised as having pin 9 removed "for universal VGA compatibility". Are different pin configurations necessary for any of the VGA-related standards? -- Beland (talk) 22:29, 18 December 2007 (UTC)
