I have an annoying problem. I problem on my old notebook I had a HDMI and VGA port however I could only extend my desktop to one additional screen. I sold that notebook and purchased a new notebook with a DisplayPort 1.2 (Tunderbolt) and miniHDMI.
I purchased this because I was told by Lenovo community that you can have 2 external screens with this notebook.
I purchased: Lenovo ThinkPad S430
- CPU: Intel i5 Quad @ 2.5 Ghz
- RAM: 8GB DDR3
- GPU: Intel HD4000 with nVidia GeForce 620M (Optimus)
- Output: 1x miniHDMI, 1x miniDP (1.2 Tunderbolt)
I plug one screen via HDMI and one via DP to HDMI cable. However I can only extend to one screen at a time. I have all software up to date but cannot extend to 2 additional screens. I went to Intel support page and it shows that the GPU supports desktop extended to 3 screens.
What am I doing wrong here ?
I know that my option is to buy a MST (Multi Stream Hub) that plugs in to DP port and from that I can connect up to 6 screens or something like that but I'm worried now If I order this 200$ very expansive MST Hub if I will be actually able to extend my screen to 2 additional monitors. So Notebooks screen + 2 external screens.
