I thought I would conclude this thread with one helpful product in the event someone is in the same position I am. My Kensington dock came in and it works great, but only for my specific need. This dock is the SD4700P and I think it came out in 2018. It does not support 4K, only 2K on a single monitor, but this is all I have so it was perfect. It does have DisplayPort and HDMI, but if you choose to use 2 monitors then the resolution drops to 2048 x 1152. So not great for dual-display. Also, let me mention that in my testing, HDMI only works for dual-display. If you want a single display, you are forced to use DisplayPort, which is fine for me.
This dock did fit a niche I needed. As I said, I only have one 2K monitor and I wanted a dock that would work with any laptop and be able to charge them at the same time. This dock accomplishes that perfectly. For my Surface Laptop 3 I simply use USB-C (the dock does come with its own robust power supply). Then when I switch to my older model Acer laptop, I connect via USB 3.0 (the USB-C cable has a special adapter for it, pretty slick) and then I also connect power via a $5.00 add-on component you can get for this dock on Amazon.com. The model number for this add-on component is K38310NA and it has plugs to power a ton of different laptops. An incredible deal for $5.00.
Additionally, the overall deal gets better. This SD4700P dock sells on Amazon for $200. I checked eBay just to see and there is someone selling the exact same dock for $30.00 delivered! So the dock I wanted that can handle all my laptops and charge them as well only cost me $35.00. I'm in no way affiliated with this seller so buyer beware, but here is the link to the dock being sold right now in case anyone finds this of interest.

For some reason the box did come with Chinese lettering on the outside, but inside it is the exact same U.S. version of the SD4700P and mine was clearly brand-new. As I said, it is working perfectly for me at the moment and hopefully gives me good use down the road.
Thanks again for all the help. Things are good now.
