VisionTek Radeon HD5450 PCIE512M , dual DVI outputs, one DP output
Dell Studio 540 Desktop
Windows 10 64bit
AMD Catalyst Control Center 2015.1104.1643.30033
2D Driver 8.01.01.1500
Dell U2515H, Displayport connected to miniDP of graphics card, 2560x1440@60p Hz
Dell U2515H, Displayport daisychained off first monitor (above), 2560x1440@60p Hz
I connected a second Dell monitor via the DisplayPort cable to the DP output of the first Dell monitor. I get identical output to both monitors.
I click on Detect in Display settings but it only lists one monitor as detected.
I click on Identify in Display settings and it shows a large '1' on both monitors.
I want to get both monitors detected, so that when I click on Identify a '2' appears on the second monitor.
I have tried with no success, the following:
-Enabling/Disabling the DP 1.2 setting on each monitor
-Dropping the resolution of both monitors to 1920x1080 to reduce the bandwidth in case DP 1.2 wasn't supported by the graphics card.
I suspect that the graphics card doesn't support daisychaining but if that was the case why does it show output on the second monitor?
Any help gratefully received.
