need help displaying 2 2560x1400 monitors on tahiti 7870

i currently own a tahiti 7870 myst edition and just recently bought two shimian 2560x1400 monitors. i was wondering which is the best way to connect both to my 7870.

here are the options that i seem to have

1) buy a mini dp to dual link dvi adapter for $80

2) buy a second video card (radeon 5450) for $30 to run the second one.

3) upgrade to a nvidia card (dont really want to)

im leaning towards option 2. is there any disadvantage to this? the second monitor is only used to watch movies / second display for adobe photoshop / lightroom. ive heard people having issues with mini dp adapters .

  1. Your card should have come with a minidp to dp adapter. Buy a dp cable and use the adapter for one monitor. For the other use dl-dvi.
  2. I forgot to mention I have a 7870 and use a minidp to dp adapter with a dp cable to run an auria 2560x1440.
  3. Why not use one on DVI and one on HDMI? Chances are you already have the cables on hand? I currently run a Powercolor 7850 running 2 1920x1080. It works fine and I already had the cables so it was free.
  4. the shimian monitors are only DVI only. HDMI highest resolution is 1080P, wont work with 2560x1400 monitors
  5. HDMI won't do 2560x1440. I assumed your card had 1 dl-dvi, 1 hdmi, and 2 minidp ports. Am I wrong? If you had 2 dl-dvi it would be cheaper to use those.
  6. you are right wandere11

  7. I thought the hd6000s and hd7000s used a HDMI 1.4a Dual Link connection for a max res of 4096 × 2160p. A straight HDMI to dl-dvi adapter cable can be had for like $5 and should work. All my monitors are 1920x1080@60 so I have never tried it and can not confirm. Although the spec on the website for you card seems to confirm that the HDMI can go to 2560x1600.

    About option 2:
    A hd5450 for around $30 or a HD6450 for around $40. Would work perfectly for your needs. Keep in mind your mother board would have to have a second PCI-e slot.

    We used this option all the time in the office for the graphic designers, so they can do e-mail and stuff with out taking any resources from their workstation cards.
  8. Is this your card?

    http://www.powercolor.com/Global/products_features.asp?id=430

    3GHz HDMI 1.4a with Stereoscopic 3D Frame Packing Format, Deep Color, xvYCC wide gamut support, and high bit-rate audio Max resolution: 4096x2160

    Am I misunderstanding how this works?
  9. bucknutty hey thanks for your help and that is my card. for some reason I cannot find an hdmi to dual link adapter. seems like one doesn't exist? if there is one that would be excellent. but a second card would be nice to take the load off my 7870. I have 4 pcie slots on my mobo
