I have a work laptop and it only has a vga port so I have to use a monitor with a vga port. The monitor has 2 hdmi ports as well, so could I use a hdmi to vga adapter to connect it to my tower. My tower needs a vga port but the laptop requires that. I want to be able to use the monitor for both but I don't know if I can. Also since the laptop only has a vga port I am using my 1080p monitor with the right port but I am wondering if I can use a 4k monitor to connect it to my laptop using some other adapter. Btw I am sorry if this is a dumb question, I don't know really anything about this type of stuff.
