I'm getting conflicting information about which chip is in the HL-R4667. Is it the HD2 Plus, thr HD3 or the newest one which some refer to as the HD4? Would I be better off with the HL-P4674?
It has the newest one, which some refer to as the HD4. It's actually an enhanced version of the .55 inch HD3 and performs mirror switching at more than twice the speed of the previous version. The higher contrast of the 67 is a result of the 5th generation light engine.
The 74 has the original HD2+ chip and a 4th gen light engine.
Each set has very different styling. Better off?......hard to say!
