I recently purchased 3 LG 25" ultrawide gaming monitors with 2xHDMI inputs only. I can get two of these monitors to run at the default resolution of 2560x1080 at 60hz using one HDMI to HDMI cable and one active displayport adapter to HDMI. The problem is that with my Radeon R370 video card the only choice I have left is the DVI ports. This card does not support the 2560x1080 resolution with a DVI-D dual link to HDMI adapter, it only allows 1920x1080 resolution. I have checked multiple forums on this issue and the only conclusion I have found is to replace my video cards (since I have two crossfire linked) and this is to costly at this point.
My question is can I use a 2 port displayport hub to connect two monitors using the displayport on the video card and then two adapters from the hub to HDMI and still get 2560x1080 resolution and have the third monitor with the default HDMI to HDMI?
Having read the product page it seems possible since it says I can use passive adapters to run multiple displays but it is the 2560x1080 at 60hz that I am concerned with, will the hub be able to power the two displays at the above res and refresh rate when converting to HDMI from the hub?
