I was asked this at an interview. The said company wanted me to create a guide as to how six monitors could be connected to a laptop for their traders.
I suggested this after lot of digging around :
- DELL Vostro 7510 laptop [Intel® Core™ i7-11800H , 16GB RAM, 512GB NVMe SSD, 15.6-inch FHD display, NVIDIA® GeForce RTX™ 3050 , 1 X ThunderBolt™ 4 port ]
- 6 X Monitors capable of running at 1920 X 1080 resolution , where 5 X monitors have Displayport DP input while 1 X monitor has HDMI input
- Dell Thunderbolt Docking station – WD19TBS
- StarTech.com 4 X Port DisplayPort MST Hub
- Dell docking station is plugged into the mains. At the back, one of the DP ports is connected to a monitor while the HDMI port is connected to the monitor with the HDMI port. The Startech hub is connected to the other DP port and four monitors are connected to each DP port on the hub.
If budget was not an issue, I would have suggsted an external graphics card.
