Hi guys, I have a laptop with NVIDIA GEFORCE GT 645M, I connect the hdmi port with a TV and VGA port with a Monitor. I realise that I'm unable to let my laptop screen work together (meaning i could only have 2 screen working at a time), can i know is there anyway i could do to let 3 screen (TV, Monitor, Laptop) work at the same time when using Extended Display. Thanks!
There is only 1 option left for you in this case, the USB to hdmi option, but its not guranteed to work.
I use a HP with a desktop dock, so that gives me 4 physical display ports, 2 hdmi, and 2 vga, but again maxes out at 2, just like yours.
It is likely your graphics card does not support it, so you might want to try the USB-HDMI option, but I personally have not tried it myself.
I see, is there anyway for me to check how many output could my graphic card support? Thanks!
