Got this monitor yesterday to replace the good old HP LP2065. The first impressions are very positive. Going from a 20" (1600x1200) to 24" (1920x1200) it's a bigger improvement than I expected.
As I mentioned in the post above yours, yes HP still ship LP2065 with S-IPS panel. At the time I posted there were about 80 GSM002 (S-IPS version) boxes sitting in a warehouse where mine came from.
No, the sku # EF227A... is not indicative of a particular panel. There have been reports of MVA...
I found this thread just before I placed my order and it really helped me. I contacted my reseller here in Ottawa and he was able to confirm with his supplier that all the LP2065 in the warehouse were GSM002 so I went ahead and ordered one.
I got it today and sure enough it was a GSM002...
