Matte screen (display)...
May you tell me please what iMac models or any , 2009 , 10, 11 got matte screen like 2006 model?
None. However displays have changed dramatically since 2006. Later models made after 2011 have much reduced glare comments regarding glare have all but disappeared on current model iMacs from end users. If you have not seen a current model iMac, go to your local Apple Store or reseller and look at the new displays. .
