Can someone link to any device that allows *extending to multiple monitors without actually install more display cards? I have a laptop that I want to use with 8 monitors and a desktop as well...Is there such a thing as a display switch that is external and connects to USB-C for example or even HDMI port and extends it (not looking for mirroring). Thanks,
If you want 8 monitors you wil need 8 monitor outputs. One USB-C connection can output to 2 monitors, HDMI to just one. There are no devices that magically increase the number of connections that your laptop/pc has, there are USB videocards but they have lagg.
USB Video Cards will be fine for Charts, too laggy for Gaming but charts not a huge issue, less data being sent, think you can get 4 outputs per device.
Go to a decent computer store and tell them what you want to do and some may even show you a real multiple monitor setup for you if you buy what they setup. Others will come to your home and configure it for you with no more than $100 extra dollar charge (e.g. Best Buy). Display Port (daisy chaining multiple monitors up to 4) @ https://multimonitorcomputer.com/solved/displayport-daisy-chaining-of-3-or-4-monitors-quick-guide.php I've seen 8 monitors before in a computer store (FutureShop before they went out of business many years ago) but I'm not sure how they set it up. Videotron had a 16 monitor setup but freaked out when I started asking questions about the hardware / configuration when I was returning new cable equipment that was defective. Yet, I did notice a display hub and whatever computer they had running all of it...very quiet. wrbtrader
Why don't you buy one or two huge 4K or Ultra Wide monitor and divide screen area into 4 or 8? You cannot avoid all the cable mess up with 8 monitors.
