Does the Geforce2MX do Twinview???

[dentar]

I have this card:

01:00.0 VGA compatible controller: nVidia Corporation NV11 (rev b2)

Model: GeForce2 MX/MX 400
IRQ: 9
Video BIOS: 03.11.01.24.40
Card Type: AGP

I have been all over this forum like hair on a gorilla but every thing I have read says that the GeForce2 MX/MX 400 cards -should- support twinview with both monitors at the same time, but I keep getting this:

(WW) NVIDIA(0): 2 display devices connected, but only 1 supported;
(WW) NVIDIA(0): adjusting...

I have a Syncmaster 700p on the 15 pin port and a TV on the SVIDEO port.

I can get them to work one at a time, which proves the ports work, but not both at the same time, which is un-cool.

So what's the deal with it?

I've been successful getting TwinView to work with two CRT's but I've never tried with TV. Post your XF86Config.

Here is the XF86Config for twin view.

Please note that I have tried many combinations and I keep getting the same message...

Some GeForce2 cards support TwinView and some do not support TwinView, depending on how the OEM manufacturer implements the DACs. All GeForce2 class GPUs have two DACs, DAC A and DAC B. Each DAC can drive one analog display. TwinView requires one display on DAC A and one display on DAC B.

A TV port is supported only on DACB for all NVIDIA GPUs. If an OEM puts an SVideo, RCA, or VIVO connector on a card, it is invariably on DAC B.

A VGA port is supported on both DAC A and DAC B. If the manufacturer provides a VGA port on DAC A, then TwinView is available using <VGA> on DAC A with <TV or VGA> on DAC B.

If the manufacturer puts a VGA port on DAC B and also a TV connector on DAC B, then output is possible for only one display at a time. This is likely how your hardware is manufactured. No driver can make DAC B drive two displays with different images.

One way to verify whether your card has both TV and VGA ports on DAC B is to check it out on the Windows Display control Panel. If the Advanced control panel for your device has "Device Selection" instead of "TwinView " then both ports are using DAC B.

Don't shoot the messenger.

EDIT: this material may qualify for a useful sticky.

At last! thank you!

USEFUL AND WELL-EXPLAINED INFORMATION!

I will check that out and find out of my card sucks or not. If only DAC B, then, well, Heck.

Again, thanks!
