Good.

That is what many listmembers here have found out.

Interesting indeed! Which goes to show there is a wide variability in those
monitors.

Way too cool for me too.

I work with a monitor calibrated to precisely 5000K. For a full scoop on
this you may want to obtain a copy of ISO-12646 Graphic technology
displays for colour proofing characteristics and viewing conditions. I am
not going to say more about this at the risk of unleashing another flame
war. If I were you I'd stick with 5300K.

Wow! So the two programs seems to agree on the measurement. That is one heck
of a good thing if you ask me.

Stick with 5300K. And yes, it is strange. I'd report that to GretagMacbeth
tech support.
