since my D450 met its demise and after a month of waiting for samsung to get their act together I have just recieved my brand new replacement tv, they upgraded me to a D490
this is my first 3d plasma, so im not sure about something and wanted anyone elses opinion on the matter.
When watching normal 2d, on bright scenes there is a definite difference between the bottom half of the screen and the top half, almost like a seperating line - the bottom half appears a tad dimmer than the top. It can only really be seen on bright whites, during "normal" viewing everything is perfect.
This occurs on all HDMI ports, VGA, Component and the built in freeview HD tuner. Switching between standard / movie mode and changing the brightness and contrast makes no difference to it.
Is this just a side effect of how the 3d panels are built or is this a defective panel? my D450 was perfectly uniform before the swap. The new TV is a brand new unit, not a refurb, manufacture date Feb 2012 so its very new indeed.
I still have 3.5 weeks of the 28 day swap out warranty before the usual "service technician" type of warranty care take place so want confirmation asap.
EDIT: forgot to mention that i have not watched anything other than fullscreen content since i got it, and have run the scrolling bars for over 24 hours without interruption to see if it goes away. the panel has nearly 50 hours on it now
firmware is the latest t-mst4deuc 1026.0 and full product code is PS51D495
