I own or have owned all the ones I linked below. I don't use my laptop as a desktop so it's not connected to any of my monitors. The reason I bought the stands is to house the laptop when not in used or when I connect it to my TV.

1. iQunix Vertical Laptop Stand: This laptop stand works well. The rubber padding is pretty thick so I didn't worry too much about possibly scratching it, especially around the opening edges. Also, the design of this stand allows good airflow if you want to have the fan vent pointing down.
2. Twelve South BookArc: This stand is probably one of the nicest stand I owned. It's everything above plus the leg slot that allows you to run your cable under if needed. If you're looking for a stand to display your laptop, I say this would be it. Also, because of the extra rubber padding around the opening of the stand, you can slide the laptop in with ease.
3. Jarlink Vertical Stand: This here is a decent stand that I liked because it's pretty minimal. It's smaller than the other two and has a nice weight to it. It's also adjustable so it should work with most laptops. However, it's kind of a PIA to adjust the thing to the right fitting if you have OCD like me. Oh, there are no slots on the bottom so ventilation isn't great depending on how you use it.
4. Seenda Vertical Stand: This is the stand that I use the most when I'm not using my desktop. It's adjustable to fit most laptop sizes and can be used as a height stand for a more comfortable typing position (I use the height stand a lot). It also has a 2nd slot where I place my iPad (this was a huge plus for me). There are no slots on the bottom so ventilation isn't great depending on how you use it. The biggest con to this stand is that there are no rubber padding around the top edges of the opening. So when you slide your laptop in, you want to be a little careful.
