Okay. I'm ignorant but what is the purpose of an USB port on a monitor? Thanks.
Updated. Never mind. I looked it up. Yes, I can see that not having multiple USB ports for daisy chaining monitors is a big negative for many people.

erm no you do not use usb ports to daisy chain monitors. daisy chaining is done using display ports, provided the monitor supports them.

usb ports on monitors serve two or maybe three purposes depending on the type of usb input they use.

1. a monitor that has a usb connection to the pc can use it for firmware updates. monitors now are becoming more and more feature rich and complicated. we need firmware updates to fix bugs and maybe introduce new features that benefit us.

2. A usb hub. having a usb hub integrated into the monitor has many advantages. It saves desk space and reduces clutter. You can plug in your wireless keyboard and mouse dongles to bring it closer to your mouse and keyboard, reducing chance of inteference and signal loss compared to being plugged into the back of your pc especially when its on the floor under your desk. You can take advantage of the additional power the monitor provides to charge peripherals and phones faster, something most pcs and laptops usb ports dont do. With multiple inputs it can act as a integrated kvm switch, brininging you all the conveniences of one to switch between multiple pcs and laptops using one monitor/keyboard/mouse without taking up more of your deskspace.

3. Although not that common, mostly available on work monitors and less on gaming monitors, there are monitors that have usb c input(s). These monitors accept video and data input via these usb c input ports. Laptops (and some desktop motherboards) that can output video and data through their usb c port can reduce even more clutter by using only a single cable to plug in to the monitor to get a bigger display while expanding your amount of usb ports. Effectively some monitors even act as docks, since you already plug in your keyboard and mouse into the monitor, and some monitors even come with built in usb ethernet. And using that same usb c cable, you can also charge your laptop. This also works with smartphones btw.

Thanks for the information. While I might have been interested in the past, my days of bleeding edge and edgy things is gone. 40 years of always pushing the edges of what can be done has left me now enjoying the simpler content lifestyle. :)
