Equium A100-147 - Native resolution on the external LCD display does not work

Hello

My Equium A100-147 has 1 VGA and 1 S-Video output, so I use the VGA output on an external LCD monitor with a native resolution of [email protected], but integrated graphics Intel 945 card doesn t give me the correct resolution to choose for this monitor, the closest is 1600 x 1200 and some weird widescreen resolutions other that make my monitor see the scaling an ugly picture.

So I tested another external monitor with a native resolution of 1920 x 1200 resolution closest gave me Intel drivers is 1920 x 1080, even the installation of two drivers of monitors, remove and reinstall the driver and same formatting the machine and reinstall everything from scratch gave no different results.

I have another laptop MSI Wind with the same graphic card built in and the same version of the pilot, and the laptop detects both the monitor and the good resolutions for them, this isn't a problem of Monitor driver.

Seems to me that is a problem with the S-video output, which makes this mess, but there is no way to disable it in the BIOS or any other place in Device Manager I still seem.

Can someone give me some advice for what can do?
Thank you!

Hello

You cannot choose the preferred resolution because the graphics chip does not support this external resolution or the installed graphics driver is not contained in this resolution. The two cases are possible.

If you want to know if your graphic chip supports this resolution and then take a look at the user manual and check it.

If the chip of the graphics card would support this resolution and you will not be able to choose, then that would mean that the graphics driver does not support this resolution.

But first he must find out what external resolutions are supported by the GPU.
