I have 3 identical LG Monitors LED 21,5" IPS widescreen 22MP55HQ-B that support 1920x1080 @60Hz each, and a Graphics Card R9 270, working with Windows 10. This GC is supposed to support up to 3 monitors on eyefinity mode and 4 using the displayport, but I only can get 2 monitors working, even using an active displayport adapter. I use 2 DVI/HDMI cables, and a displayport with active adapter/DVI/HDMI. The computer "uderstands" there are three monitors plugged in but only two send image. I thought it was a problem with the active adapter but if I plug the displayport/adapter/DVI/HDMI to a LED TV I can get the 3 images working. What can I do to put this image to the monitor?
