Dark blobs have appeared on my laptop screen in two places, it looks like someones constantly pressing on the blobs with there fingers. Ive tried rubbing the screen to see if it'll sort it but had no luck. Anyone know a way of clearing them or is my screen [toon edit]f****d broken?

Uhm, yes I think your screen could be broken...
Try to check if there's some new electromagnetical device near your laptop, but if I understood exactly I had the same problem when my cat jumped over the screen and then happened the same boiling-blobs effect.

Anyway I'm not a hardware technician. Hope I'm wrong

If this is a laptop ur talkingabout mate then its probably a crack and its a leek...the blobs with time might like start branching out and it groes.

If Monitor for the pc, then i have no idea im sorry man
