I've had both. I slightly prefer the PA27 but both are good units. The 30 and 27 have the same width but different aspect ratio. The 30 is huge! It also appears to have run warmer which is to be expected. Advantage of the PA is you can use MutliProfiler and/or SpectraView. If you got a great deal on the 30, go for it.
Well I finally bit the bullet on the PA 271W - purchased from Image Science in Melbourne - I paid a bit extra to avoid the "virtual" experience of the online alternatives.
In the end I appreciated the advice I received and the piece of mind that if I need assistance it's there.
I decided the PA271W was the best compromise for size/image quality and price.
All working and Wow what a difference! I discovered half the colour spectrum has been missing!
Also bought the i1Pro calibrator - but the monitor was well adjusted from the factor. It seems to work well with the Spectra view software.
Couldn't be happier........
Thanks to everyone for assistance
