Remember, they are trying to get rid of last years model.
And I would whole heartedly disagree after a side by side, almost setting by setting observation. I bought my 640 from Pauls for $1349, 1440 out the door. 73738 next to it. Yes the 738 had 2200 hrs as opposed to the 400 hrs on the 640. But I was hard pressed playing with the basic settings(brightness, contrast, tint, color) to see a difference in actual PQ. Not to mention they only took $50 off the floor model for a price of 1549 for the 738.
If you don't have the need for the internet apps, get the lesser expensive model, also has nice Advance Picture settings menu every little color calibration you would want. Only issue I had was in 3D, the DLP Link mode turned the screen a very distinct green, even with the glasses on blacks were still tinted green. Thanks to people in that thread, I will be getting an IR emitter and fully enjoying this tv soon. (3D was still awesome, just the Green tint was driving nuts.)
Menu button, 2-4-5-7 and you're in the screen position settings, that you adjust using the directional key. Hit 0 for Geometry Settings menu which worked great for getting the picture straight on all edges. The other settings I have no clue of yet, other than DBLK which is set from 0 or 1. It made blacks darker, but I am not sure that was its intention. Hopefully as more people buy this set we can get some other tweaks/calibration settings.
