They are all both 60hz or 120Hz depending on your language. These sets are all wobulated. That means that they shift over one pixel. They display 960x1080 or a half of the horizontal pixels in a 120th of a second. In the next 120th of a second they shiftover one pixel and display the 960x 1080 or other half of the pixels. So call it 120HZ yes, call it 60 HZ yes.
What they can't do is diplay a full 1920x1080 frame and all those pixels a 120 times a second none of them, no matter what they call them. In fact because they overscan you can never see all the pixels anyway. Aproximately 5% of the pixels are projected beyond the edge of the screen. Smooth motion and al that are hocus points has to do using what is essentially some kind of interpolation of the original 24fps or 30 fps or 60fps data sets during using these 120 hz half frame operations.
Understand DLP as it is implemented on a TV is a native 960 x1080 120 hz technology that when wobulated creates in your eyes/brain the same effect as seeing a 1920x1080 60 HZ display. That is a sufficiently high frame rate to reproduce all the traditional 2D formats. When 3d is done on a Wobulated 3D ready DLP the mirrors are flashed in each 960x1080 half frame in such a way that a 3d sterescopic effect is achieved. That format is called checkboard.
The procerssor and the memory is much faster than the mirrors on the chip and as result DLP can produce a vey high quality 3D stereoscopic image. There is perceived resolution and acutal resolution. If one technology produces an actual 3D resolution of 1920x1080 pixels 60 times a second per eye and another technology produces 960x1080 pixels 60 times a second per eye one might be tempted to automatically assume that the technology that produces the highest actual resolution will produce the highest perceived resolution... this would be true if everything else is always equally but we know that everything else is seldom if ever equal.
The proof is in the pudding. Yes, wobulated DLP can only produce the lower of the two actual resolutions described above. But for a number of reasons, the perceived 3D resolution with DLP is very high, many will say it produces the higher perceived resolution in 3D desptite, the lower specification. DLP properly implemented produces a very high quality stereoscopic effect. You really need to understand that we are dealing with an optical illusions when we watch content on display technologies, esecially when we get to stereoscopic 3d. It is the quality of the illusions that matters not necessarily the actual resoltuion.
It reminds of the commercial where the guy brags about his audiophile tube amp that reproduces frequencies that only dogs can hear. I think you should take off your "Justintoxicated hat" and try on the one labeled "thinking cap) for a little bit and go read about DLP instead of going on and on in these forums with the endless concerns you have.
Right now on consumer television no matter what brand or model, whether Panasonic, LG, Sony, and others may tell you otherwise... DLP is what's happening in 3D... check the 3D threads. The sets are big, 3D needs a big display to produce a reasonable stage for 3D. On DLP the pixels turn off and on the fastest, so you can less ghosting and other artifacts and less crosstalk.
You seem to be extremely focused on whether your set is 60hz or 120hz. If you will just understand that they are all the same regardless if it is a halo product like the 82838 and 75" LaserVue or your entry level 60638. They all use a wobulated DLP DMD chipset.. whether Mits makes available a gimmick like smooth 120HZ on the 638 models is meaningless, because it is a useless gimmick it will only make changes in the source that are most likely not inline with the director's intent and will negative and objectionable effects. Anyone with half an idea what they are doing will have that feature turned off on their sets if it is there.
I know nothing about the 638, but it entirely within the realm of possibility for Mits to not give access to 3D on the 638 if they so chose, if the sets did not have this 120HZ capability I have painstakingly described you could not 3D on your set. Based on my quick check is is listed as 3D ready just like all the other sets for the last several years. So what the heck is it that you still don't understand? You are spinning your brain in circles over nothing, there is some image processing crap that Mits usues to differentiate models at the different price points... most of this stuff is useles and acutally counterproductive whether it be deep field imager, 120HZ smooth motion or god knows what.
There a 3 things of note that really make a difference.
1) an iris found only on the 838 and early year equivalents
2) Perfect Color found on at least 738 and 838 and early year equivalents
3)Perfect Tint found on the 838 and LaserVue and early year eqivalents
4) One can debate the usefulness of the Advanced modes where ever they are found.
If you don't like your set and you don't like Mitsubishi and you don't like your dealer... go out and return it if you can, if you can't unload it, take the a couple hundred dollar loss and move on. Please I don't know about others but I am having a very hard time staying patient with what comes across to me at least as hopelessly uninformed whining.
