GEforce and forum images.
 

I have got a laptop with A 765m in it.

I take the odd photo or two which most of the time look great when posted up on FB or the like.

Now I have a night pic of the northern lights which is showing up weird on my machine. Its fine during getting lightroom'd and viewing the export.

Just when you up load it the image takes on huge blocky lumps of colour shade without any progression between shades and sometimes jumps giving a checkered effect.

I have tried OEM drivers, the current drivers clearing browser changing browser etc.

Anyone got any more ideas to try?

Apparently others can see the image fine.

Is it limited to one filetype (eg .jpg)? Don't get excited, I'm just thinking out loud!

will try another one but only tried jepg so far.

I have had reports back that its happening to other people as well across a variety of os's including Mac. We all have Nividia cards.

There is also some debate about if Adobe colour space or RGB is making a difference. I haven't been able to get any colour gradient photo's to try this theory out yet.
