did you see this quote on your link by 64dynamic :
Yes, I did.
That is one of the reasons why I pointed out the links ...
Any comment. the 2007 wide is only ~$340! Would you still say it shouldn't be used for critcal work?
If it can't be dimmed enough, it shouldn't be used for critical work. If it can be dimmed, it probably can be used, since the colour profile from calibration can be used to compensate for almost any other weaknesses in colour representation.
Kaelaria's post indicates that you have to dim it quite a lot in software, which really isn't a good thing for colour and brightness accuracy. He also appears to have a different idea of what "critical work" means than what's usually understood by the term.
This does not necessarily mean that you will experience problems with it, but it increases the likelyhood significantly.
I realise that this may not be the advice you want, but I really can't tell what you might find acceptable or not. But when colour management experts (and I'm not one of them) state quite clearly that LUT adjustments of brightness should be avoided, it's a good idea to pay attention.
