    Question DVI-D Dual Link to two Seporate DVI-D Single Link Moniter Adaptor AMD R9 270

    Stupid question on my part but for once my search engine skills are failing.

    Have a AMD R9 270 which I am sure the docs says support up to six monitors but only two work at a time. It probably requires an active display port connector for at least one but this setup is two dvi and one HDMI.

    I am thinking that because of the clocking signal it will need a DVI-D dual link to two DVI-D single link adaptor. I have seen this product before but can't seem to find it with search terms. Surely three monitors should not be this difficult and displayport monitors should not merit a 1/3d increase in price.

    Any help in sorting an easy solution greatly appreciated, I don't want to be recommending active displayport adaptors at $100+ if I don't have to.

    I take it you want to use extended desktop rather than duplicated screens. As far as I know this can't be done. Dual Link isn't the same as duel head. The extra pins provide double the data rate so that you can use a much higher resolution monitor. If you are happy with duplicated displays then just search for DVI-D Splitter. You need to use separate outputs to each monitor if you want to use extended desktop.

    Are you thinking of a DisplayPort MST Hub? e.g.


    As Pete said, you can't convert 1 x (DL) DVI into 2 x (SL) DVI.

    Hmm, must have been a special card I was dealing with, As it happens the user does want one DVI output mirrored onto HDMI but with audio etc. so that cold be interesting. I guess I'll keep playing with adaptors to find out what AMD are on about with 6 monitors, they probably mean 2 monitors duplicated three times with y adaptors :P

    You may need an active DisplayPort adapter perhaps?

    The DMS-59 connector sometimes gets confused for DVI.
