Gary has a computer with a gaming video card to connect multiple monitors. Can he use three 4K monitors or a QuadHD monitor? Leo says it doesn't matter. Modern video cards can display 4k with no problems, even in HDMI. You can also add a monitor through the display port. What is dual-link DVI? Leo says that was something they came up with for the Display port to drive higher resolution monitors. But HDMI can handle 4K now, so that doesn't matter.
Henry built a new PC, and he's having problems with his AMD Formula 8 motherboard when he tries booting up. It looks to be an issue with his Display Port. Leo says the first thing to look at is the display port cable. If it's gone bad, that could cause problems. Leo also says that this is the problem with building your own PC. You are your own tech support, and every part manufacturer is going to pass the buck when you call them.
Paul was recently gifted an Apple Cinema Display. But it doesn't light up if he plugs it in. Leo says there's no on/off switch on that old ACD. You just have to plug it into a computer that has a display port to get it to turn on. You may need an adapter for Display Port to HDMI.
Paul wants to also know what's the best streaming box. Leo says that Roku seems to be the most compatible, but some ISPs have deals with other boxes like Apple which can give it better programming or preferred traffic. So Apple TV may also be a good choice depending on your ISP.
Mike wants to know if he can use more than one monitor on his computer. Leo says that most modern-day computers do support multiple monitors and both Windows and macOS support it natively. But the computer has to have more than one display port or HDMI port to do it. Most do out of the box these days.
