Hi everyone.
Thought I'd chirp in with my experience now that my monitors have arrived and things have been resolved to my satisfaction.
Ordered 2 Shimian's from green-sum

(top bloke) on Friday July 27th 3.00pm UK time.
They arrived Tue 31st @ 10.47am - wow! Fast!
Undid the packaging to discover I only had one power supply - damn!
Used that to check both monitors - no dead/stuck pixels and minimal back-light bleed.
Notified green-sum via email and asked for power supply to be sent.
Wed 1st Aug got reply asking for photo of items contained in the packaging - sent photo.
Thurs 2nd got confirmation that new power supply would be sent at no charge.
Fri 3rd Aug got tracking number for DHL - I expect power supply to arrive Mon/Tue.
I just wanted to share my experience.
I was gutted when I opened the packaging to find power supply missing and started worrying about shipping costs, etc., but mistakes happen.
What is far more important is how green-sum resolved the situation for me speedily and at no cost. I would definitely recommend.
Also if anyone in the UK is looking for replacement power supply for any of these IPS panels, I had a bit of a wild goose chase looking to cover my ass in case green-sum had'nt turned out to be so good.
There are compatible power supplies on ebay with the correct pin polarity, but the only one I could find was from a
US based seller and had the mickey-mouse adapter plug.
Far better for UK buyers, and with a decent kettle lead adapter like the Frontek I found this from
Hazro, although they don't appear to link to this page from their website! Hope this might help someone.
Mike
