On 2nd new Z2 now (first one had purple dots everywhere). This one seems seems perfect except for 1 errant pixel that shows up pale green but only on paler colours (invisible on white, black, pale grey and mid to dark colours). It's about 2/3 across, 2/3 down at the moment (but we'll be inverting the PJ when finally mounted, so it'll be top corner). It seems to be pretty much invisible from our viewing position, particularly since it's not permanently stuck. Is the quest for total perfection the way to madness? It it better to stick with the devil you know rather than risk a worse gremlin from yet another swapout? Will I forget about it the day I get the first dust blob anyway? If I try it sell it in a year or two, will the cry go up "misfiring green pixel!!! Unclean!!"?
