Thank you philjohn for the answer...
Actually I didn't used that "secret cleartype settings" from HardForum, I think I'll replace it as soon as I have the right to do so, as dead pixel concern! Can I do a replacement at any time, or do I have a days limit to do it?
I've made a search to the the link you refer about the HP policy, but I didn't found it... are you sure it was in this thread?
Thanks once more time m8!
Any one more info about the "secret cleartype settings"? My text looks fine after a bit of tinkering.
