"Dying" monitor

Recently I always complained about my quite troublesome monitor here. So let me explain and show something.

So when I switched on the monitor, it becomes.....

Nothing but some "rainbow"??

So frustrating because I cannot use the PC, simply because of the MONITOR!!!

Trying everything to get it working and displaying! Arrgghhhh...!!!

But then, more funnily, the monitor can function properly ONLY AT.....

I HAVE TO TILT IT LIKE THIS, THEN IT CAN WORK!

No joke, I know it's seems upright, but it's real, I really need to tilt it! It simply doesn't make sense because it make me hard to read the screen!

LOL!

Anyhow, just hope can get a new one, AS SOON AS POSSIBLE!

God bless you all!
