Rainbow/white affect on monitor screen

[Archer88]

 Hi. Does anyone know how to fix or what causes my screen to do the above(pics). I play my ps5 console on the monitor.  And after around 20-30mins of gaming my screen does this. If I shut everything down and wait a few hours the screen will work again but just for another 20-30mins again. I've tried HP and they said they can't do anything about it, other than myself buy a new monitor . The monitor is barely a year old so really disappointing that this has happened.  Any help will be appreciated, thanks

Hello
you need to check, if there is the same problem with a computer
If no matter what device you use, the screen is probably damaged.
But it may be quite complicated to identify the source.
You should therefore consult a professional, but the repair cost may be quite high, on that account in fact, it will be better to replace it.

Thanks for the reply. 

Amazon are going to take it back for repair,

Under warranty ?

Amazon had a two year warranty.  HP only one. If Amazon can't fix it they said they'll send me a new one.

It is probably this, two years legal guarantee

Consumer legal guarantee

I didn't know he was less than two years old, otherwise, I would have told you that right away!
And in general, without wanting to advertise, they are good in case of problem, we bought a printer, and suddenly we had problems with the scanner.
We asked for a simple support
And they told us to send the printer back, and to choose another one, replaced very quickly then!
