Notebooks now have 2 videocards and one can switch between them on the fly.
How can I do it on my PC-box at home? I want to switch between video cores in processor and discrete video. My monitor should be plugged into only one place (discrete videocard or motherboard).
Is this possible, or can it only be done by plugging monitor cable either to videocard or motherboard?
There is some additional infrastructure to support the switching, along with some shared infrastructure.
Clearly there is only one output, so that is shared, but there is also some ACPI extensions that allows the switching to happen, and some userland software so that windows can deal with the transition to a different card.
If you want silence, but power, then there are few fanless but still relatively powerful graphics cards out there: SPARKLE SXS4501024D5SNP
Gigabyte do a fanless series too.
The notebooks that support switching from one graphic card (GPU) to another one usually use Nvidia Optimus technology (I don't know if there a similar technology) which is only available for notebooks running Windows 7.
monitor should be plugged into only on place (discrete videocard or motherboard). Is this possible now?
This is just extremely alogical. How to get data from disconnected input? Two cards - two inputs into one monitor or two monitor. Period
