Multiple monitor resolution calculator
The integrated GPU was disabled automatically, but let a system support up to four displays once activated.
All of this is on top of PCI Express's ability to support multiple graphics cards, even from a 1x lane connector.ĭon't become obsessed with add-in cards though - integrated graphics on recent motherboard chipsets will happily work alongside these.īack in 2007, the AMD 690/780 chipsets that offered SurroundView often had to be enabled within the BIOS.
Interestingly AMD also offers the rather rarer Radeon HD 5870 Eyefinity 6, which has six physical DisplayPort outputs. The latest high-end Nvidia 500 series and AMD 7/6000 range can drive four physical connections. The majority of cards still provide three, usually via DVI and either a DisplayPort or HDMI output.

These days life is easier, as the DAC element can be dumped and replaced with TMDS, which handles the job of encoding the digital display data into a robust digital serial signal fit for shooting along cheap DVI and HDMI cables.ĭespite the size of DVI connectors, the switch from analogue to digital has enabled card manufacturers to gradually increase the number of video outputs on a single card from two up to six.
Those were happy days - a RAMDAC generated the analogue VGA output, and multiple monitors could be supported by adding more. Now you know where the monitors will go, how will you connect them? Once upon a time, graphics cards could only drive a single display.
