The other annoyance/problem with DOG's must be the danger of screen burn. Having still got a good old CRT set, I don't have that problem


Screen burn generally affects CRTs much worse than any other (commonly used) screen technology
Weren't early plasmas particularly susceptible? There's one in the BBC Club, no less, which still has a very visible News 24 tower.


Yep - and they still have image retention issues (though only in extreme cases are they permanent). LCDs can suffer burn in as well in very extreme cases. (I've used PC LCD monitors with burned in IE logos and Windows minimise/maximise/close buttons)

My dad's 37" Panasonic plasma has a very visible BBC NEWS logo from the BBC News channel dog/ticker combo burned into his.


I've only seen a couple of Plasma TVs with permenant burned in graphics, but lots of CRTs with it permenantly burned in, some which you can see when the screen is powered off. Sheffield rail station used to have a spectacular example in the ticket office, which was so burnt in you couldn't read any of the times, destinations or platform numbers, they were all just a grey mush, I've never seen a plasma damaged to that degree.

I didn't realise that CRT's were so susceptible to screen burn (me not teccy Laughing ). Currently, I don't watch a vast amount of progs with DOGs at the moment.

But the BBC One HD DOG is in the very top left corner, fairly difficult to notice, and will probably only be a nuisance if you look for it.


Well if it's difficult to notice, surely it is doing no good by being there and should be removed. Smile
