in general, 2 moniks are really not enough. need 3rd, to drop a glass and a tape with a watchlist there, and on the other two in small cells already start up the charts.
my iron is a little old – 2x year ago. I don't want to update anything, because. just recently put the system cleaned and tuned.
3rd monitor connection options:
1. look for vidyuhu on PCI x1 and connect there (there is no second PCI x16 slot on the motherboard)
2. take usb monitor. Will the USB LG Flatron have the same matrix and the regular LG Flatron, 2x years ago? three different monitor manufacturers somehow do not want to.
3. look for a vidyuhu, which supports 3-4 Monitor (the most expensive option) , but they say, that vidyuhi are noisy and fry.
4. buy signal splitter matrixhead2go (not cheaper than the previous version)
5. самый low budget choice – find a motherboard for my atlon x2, which supports sli-mode and insert the second video card there (there is a card – lying in a box).. but then i get to reinstall the system :((
what i missed?
