GPU HDMI triple problem.

Describing an issue I've been having since forever with my current build.

Around a year ago I managed to put my first build together, it ran smooth then and so does now, but there's some problems which I believe are totally correlated to the GPU (Radeon RX480) and HDMI with it.

First problem: the PC loses signal with the monitor very easily. As in, unplugging the HDMI once and plugging it back in will cause, 99% of the times, the signal not coming back with me being greeted just by a black screen.
Fictional scenario: I have to plug in another device in my monitor's HDMI port. I unplug the PC's cable, fiddle with the other thing for a minute, then put the PC's cable back in... nothing happens and I have to restart the computer.
No matter the driver updates through time or the Radeon's port on which the cable is plugged in, the problem always persists.

Second problem: due to the above, if I try to restart the computer, I have to unplug all of the USB-connected devices, or else, it won't boot. AsRock motherboard screen, blue window logo and spinning circles, black, then only loading spinning circles and it stays like that forever. This is apparently a Windows 10 issue that has been going around for 2 years and that Microsoft still hasn't managed to fix.

Third problem: Unfortunately having spent all of the money on my build I had to buy a terrible Samsung monitor with just one HDMI port, and as I try to connect my PC and PS4/Raspberry Pi through the monitor with an HDMI switcher, it works painfully bad.
First off, if I try turning on the PC while it's connected to the HDMI switcher, it doesn't boot. Bad.
Turning the computer on, then connecting it to the switcher makes it work well with no input lag and good image quality. Unfortunately after about 5 minutes it loses the signal and even if I unplug the switcher and plug directly the HDMI cable back in (first problem comes back in), the signal is still missing. I have to crawl down the desk, take off all USBs devices like my NetGear key, the keyboad, the mouse, hard-turn off the PC by holding the power button for 10 seconds and then turn it back on, wait for it to load and plug everything back in.

Thanks in advance.

I've been having artifacting on my RX 480 XFX for a while now. Only seems to appear on YouTube. Once it was caused by a driver update, but rollback solved the issue, though pretty sure my problem isn't GPU related. However, on to your problems, do you have any other monitors lying around? Try it with the other ones, see if you get the same problems. If it works fine with other monitors, it's a monitor issue. Also try different HDMI cable with different monitor, and different cable with same monitor is my advice. It might be a bit overkill, but it'll help troubleshooting. If neither work, probably an OS problem.
