Mitsubishi WD-XX735,736 and 835 Settings and Tweaks

After calibrating my WD-65736 I thought it would be a good idea to start a thread on calibrating the new Mitsubishi's. This way we could have a central place to share our ideas and settings. I initially used ColorHCFR to calibrate my TV but after experiencing freezing problems and inaccurate results I ended up using CalMAN to calibrate my TV.

Here is a little breakdown on what I used to calibrate my 736. First set the TV to Low color temp and then take a grayscale and primary and secondary colors reading and save it as your before settings. You can then refer back to this when you are finished to see how much your TV has improved after calibration.

To access the service menu, on the remote press Menu and then 2,4,5,7. This will bring up the service menu. The video button scrolls through each setting in the service menu. UP and Down changes each value, and pressing Enter (or OK) not sure what it is exactly on the remote since I do not have it in front of me, saves the changes.


Then I set my contrast and brightness in accordance with the "Calibration for Dummies Link" (see below). Next I calibrated my grayscale. G(RGB)L the first few settings, adjust the upper end of the grayscale, while BM(RGB) adjusts the low end. Once you get your grayscale correct, calibrate your primary colors, and then secondary colors.

Each color has the follwing in the service menu, with what I guess each could mean:

G(RGBCMY)L (Gain)
S(RGBCMY)L (Saturation)
H(RGBCMY)L (Hue)

Here is what you are going to try and calibrate each color to if you are using a high definition calibration disk:

Rec. 709 (High Definition)
--------------x-------y-------Y
Red----------0.640---0.330---0.2127
Green--------0.300---0.600---0.7151
Blue----------0.150---0.060---0.0722
Yellow--------0.419---0.505---0.9278
Cyan---------0.225---0.329---0.7873
Magenta------0.321---0.154---0.2849
White--------0.3127--0.329---1.0

Use these to dial in your colors. Once you have your colors correct, test your grayscale again and make adjustments if needed. Everything effects everything, if that makes any sense, so make sure you recheck your grayscale after making changes to your colors and vice-versa.

One more tip, make changes in the service menu and then exit out to take the readings. You will see why, the colors and brightness differ when you are in the service menu. Those of you with 835's might have an easier time than I did since you have perfect tint, which I don't, only perfect color. So I had to adjust the tint/hue, of each color in the service menu. I was able to get my primary and secondary colors except for Blue and Red close to perfect. Which after a many tries I believe is a limitation of this TV.

In case you don't already have it here are a couple of links, the first is the calibration for dummies guide, and the second is the calibration disk I used, AVS HD 709. The third is for CalMAN, the calibration software I used.

Here are my current settings. These might give you a good starting point, if not you can always reset your service menu back to defaults by pressing 0 while in the service menu, and selecting restore white balance, first option I think.

Good luck and be patient. It is very tedious, make small changes and take readings. It is worth it though once you have it calibrated. Let me know if you have any questions or problems. I've attached a pdf of my calibration report.

I had to recreate this thread due to the data loss that happened on the forum. I think I have started the original post as it was the first time the thread was started. However if you notice any info that is missing please let me know.

Yes, I am extremely happy with the colors now. It helped shadow detail as well. Cnet's review was accurate about the colors being off. Mine were actually further off than their's was. A professional calibration will definetely make a big difference. Have you thought about calibrating it yourself? It will cost you less money and it really isn't too difficult. You will also have the hardware to calibrate again every few months as the bulb ages.

Yes, I'm running my sources through an Onkyo 604 and do not have a problem with the settings not saving. That is stange that it is happening. Is it only happening to those of you with Denon's or other receivers as well?

My set had the exact same problem you are talking about when I calibrated with solely a calibration disk and color filters. No matter what I did I could not get it correct with Perfect Color. Are you calibrating with color filters as well or are you using a colorimeter and ColorHCFR? When I finally hooked up an i1 I found out how far Magenta was off and the only way I could correct it was with the service menu. You could try my service menu and perfect color settings for magenta. In the service menu Magenta has the following values to adjust:

GML
SML
HML

Write down your default settings so you can change them back if it does not work for you. Or, if you have an i1 you can post a calibration file and I'll check it out.

Seriously, it really is not that difficult at all to calibrate it yourself. Just follow my first post and look at the calibration for dummies link I have posted and you should be good to go. It just takes a little time. It will cost you $140 for the i1 LT, and the software program and calibration disk are both free (see my first post for links). The thing with bulb based dlp is that the picture changes over time as the bulb ages so if you owned the calibration equipment you could calibrate it any time you wanted or needed to.

Either way you go, a professional calbration or calibrating it yourself, you should see a big change in picture quality once it is calibrated.

No problem at all.

Do you happen to have a before calibration file? This will make it easier to give some advice.

sounds good. I noticed that you have notes that you have your color set to 41. This might be giving you the unnatural look you are talking about. Have you tried settings color to it's default and then individually calibrate each color with perfect color and the service menu?

I also checked your luminance for your primary colors and they all seem to be a little high. Try taking each down a notch or two in perfect color. I also updated my original post with the target values for primary and secondary colors when you are calibrating. I'd be interested in seeing a before calibration file to see if your gamma was a little more in line, because you are right it does have a definite dip in it after the calibration.

Also on your grayscale blue seems low on most ire values. Try bumping it up a few notches on both the low and high end.

Sorry, I have never seen the movie and do not have it to test it out. Do you see this on any other movie? What are you watching it on, blu-ray, hd-dvd, dvd?

Glad you got your gamma in line. Just a thought, have you tried lowering CM(RGB)? This might lower your luminance and also not sacrifice your ftl. You'd have to raise your contrast a few notches to compensate but it might bring your luminance curve in line. You might try lowering each 5-10 clicks to see what it does.

Also, I would worry too much about the 10 ire reading. As long as it looks good 30-100 you should be good to go.

I had to do the same thing with my set as well, raising CM(RGB) to calibrate the grayscale and bring my color values in line. I agree, it does seem to be a type of contrast but a different one than what you can adjust in the user menu. I glad to hear it all went good. It is a really great picture once it is fully calibrated. My wife still comments on how good it looks.
