i have three sreens in 1920×1080( 24′) and one screen in 2560×1440( 27′) .
I have two screens connected like DVI>>DVI and the other two (including the 27′ in2560x1440) are connected to a clubic3D MST HUB display port: DVI >>> DP for the two screen. But I only get 1920×1200 maximum resolution instead of 2560×1440 for the screen 27′ 2560×1440 . I don’t understand why … Is it a problem of card ( gygabite AMD radeon R7260x 2gb ) or a problem of software ( eyfinity) or a problem of cable ???
My card’s seller (LDLC.com) said to me : “The problem you encounter here certainly due to the limited horizontal resolution possible via AMD Eyefinity technology. Indeed, the maximum resolution is 8192 pixels wide. With three screens in 1920 over the screen in 2560, it reached 8320 pixels … that the card can not handle, therefore the fourth display switches to 1920 * 1200, which drops the total display width to 7680 pixels. There will not simply a hardware problem with the screen, wiring or the graphics card, but rather a software limitation…. , See if it is possible to create an “eyfinity group” for your first 3 HD screens, then position the fourth screen above independently. This should allow you to display the correct resolution on your new screen.” Is my card’s seller right ? Is that the problem? Or is it another problem ?
I understand the solution proposed by my card vendor but I have the feeling that the solution might be here with a magic cable clubic ^^ what do you think ??
Anyway I don’t know how to use eyfinity so I don’t know how make one group with 3 screen and a second group with the last screen in 2560×1440 …
So i need a solution with a magic cable ^^ Maybe a DisplayPort to DVI-D Dual Link Active Adapter Cable connected to the hub to the screen 2560×1440????
Best regards !!!!
