On my toshoba pc 17'' sreen I have black spot on the top corner and the bottom of my screen , is my screen diying oley one year old
There are two types of black spots.
The first, I call bruising. This is a dark area on the screen that can vary in size and still allows for proper viewing. The second is a black dot.
If it is a black dot about the size of the period in this sentence, it is a dead pixel. Most manufacturers allow for up to 5 dead pixels before they will treat it as a problem. In either case, dead pixels and bruising are more of an annoyance than anything. I have seen screens with both issues work for up to 5 years under these conditions. They will eventually fail but how long it takes it to fail, is anyone's guess. There are numerous outlets for new or used screens. If you plan on keeping this for a while, I would recommend contacting the manufacturer to see if they will do anything or pick up another screen and have it on hand to replace it if it should fail.
