Post HDTV/Display Calibration thread
so over the weekend i got the Xrite Colormunki Display delivered. and to my surprise, or i should say i wasn't that surprised, the factory colors were pretty off on my HDTV.

but here's my review on the Xrite Colormunki Display i posted on amazon.

in case you're wondering, this really is a i1Display Pro meter in disguise. lets lay all the cards out on the table. it's exactly the same hardware as i1Display Pro. only difference is the firmware that's inside has a slower measuring time (to match the lower pricing), and the profiling software that comes with, is watered down. but if you're intended to use this with a 3rd party Calibration software, there really is no reason NOT to get the colormunki instead of the i1Display Pro, since all you need is the hardware, which is exactly the same. the measuring time isn't that much slower than the i1Display Pro. in fact, i was shocked how fast the readings took. i came from Spyder 2, Spyder 3, which took 5 times longer than what this thing takes for each luminance reading.

Pro:
it's fast, and "supposedly" accurate in measuring low luminance. Since i have no way of comparing it with a $28,000 CS-2000 Spectro meter; again, i did my research before purchase. and most tend to agree in its dark accuracy. in fact, i was able to get a reading of 0.013 cd/m2 (that's 0.0037 fL) out of my Samsung 60ES8000 in micro dimming mode in 0% IRE gray scale full field test, which dims the backlight to the minimum in dark areas. i don't know if it can read any lower than that. if i turn the backlight completely off, it wasn't able to take the reading. so i am not sure if it has any room between completely off vs what i got. maybe someone with a high end plasma can chime in and comment.

the meter is pretty consistent across the board. the resulting delta E is very consistent. you might get a bigger variation due to screen uniformity rather than meter reading. i used it on one high end Samsung HDTV 60ES8000 (the highest consumer model in 2012), one 27" Apple Cinema Display monitor, and a macbook pro. for both the 27" monitor, and the laptop i used the included Xrite profiling software, which is easy to use and quick. the whole process took 5 mins.

Speed. the measuring speed is fast. i believe the 0% IRE black took about 6 seconds max, while the rest of the 10~100% IRE gray scale took anywhere between less than 1 second to 2 second each. so it's surprisingly fast. due to this, i was able to do real-time calibration with ease by taking real-time readings in HCFR and adjust the white balance and CMS accordingly to get to the reference target point on the CIE chart for my Samsung HDTV.

the meter is supported by quite a few 3rd party calibration softwares such as HCFR, and it needs no additional HCFR meter driver. it works right out of the box with HCFR with the provided Xrite driver. make sure you disable Xrite system tray icon, otherwise HCFR won't recognize the meter.

Display type supported. the Colormunki Display supports most of the display technology out there, CRT, CCFL LCD, White LED, RGB LED, wide gamma, and projectors. this is very important. i came from Spyder 3, which supposedly supports White LED, but the result was poor.

Con:
the supplied Xrite profiling software does not include a ICC profile manager that allows you to instantly load, and change different profiles like Datacolor does. so you'll have to go into windows "color management" yourself and do it from there. make sure that you go into Advanced panel, and "change system default", load up the profile of your choice, "set to default" AND click on "advance", and MAKE SURE you enable "Use Windows Display Calibration". this last step will tell windows to use your choice of profile and load it up in the LUT everytime you enter windows. without this last step, your profile won't load.

Additional Comment:
i see some negative reviews on this product from users who got very brown/yellow looking results. let me just say this. if your equipment (monitor/TV) is already subpar. a colormeter won't be able to change that. as most laptops come in cheap TN panels with very poor color representation, my Macbook Pro (cheap TN panel) also came out brown and yellow, and there's nothing you can do. a colormeter is suppose to improve your panel to get it to near perfect, but if the panel is already bad to begin with, which most laptop panels are. you're not going to get the result of a perfect color by using a cheap subpar panel. my HDTV (S-PVA panel) came out great after the calibration, and so did my 27" Cinema Display (S-IPS, which was already quite accurate right out of the factory, that produced a pre-calibrated reading of less than 3 delta E already. after the calibration, i was able to get the delta E down to 0.38. so bare this in mind when shopping. my advice is, if you're going to be using this on a cheap TN panel, don't get your hopes up too high, you might be better off saving the money for a better panel instead of putting your money in a Colormeter.

Closing Comments:
if budget is of concern, get the Xrite Colormunki Display. if not, get the i1Display Pro, which has a even wider range of 3rd party software support, and a more advanced factory profiling software. but i would definitely NOT go any lower than this Colormunki Display, and stay away from most of the Spyder from DataColor. you'll save a few bucks, but the result will be lesser than what the colormunki/i1Display Pro can produce.


and here are the results in graphs. i should mention that pre-calibration, the delta E on my Samsung 60ES8000 was some 20, and temperature was up to 9000K, with gamma down to 1.7. needless to say, it was pretty well "off" the reference. but as you can see, after calibration, i was able to achieve a gray scale delta E value of 2.66 (anything less than 3 is pretty damn good and almost indistinguishable to the naked eye), color delta E of 1.8, and temperature of 6500K.

I have a Spyder4 Pro, it works pretty good in my mind as well. Works fine with HCFR too but the lack of settings on my TV didn't really help me get anywhere. Granted the settings I had on my TV were already pretty close to 6500k and 2.2 gamma as it was taken from some other forum members who spent all the time tinkering with the few options available and a colorimeter.

One thing to note with the Windows ICC profile management, I find some games have a tendency to "reset" that and thus the profile never reapplies unless you do so manually or reboot your PC. At least with the Spyder, it's always running in the background and re-applies the profile as needed.

You are correct though, shitty panel = shitty calibration. Nothing I do can fix the horrendous screen on my Samsung laptop (never buying a Samsung laptop again for various reasons).

Post Re: HDTV/Display Calibration thread
i find Crysis series tend to reset all the profiles. other than Crysis, i haven't noticed any of my other games do it.

i am sure Spyder 4 is better than the 3. i went straight from Spyder 3 to the i1 Colormunki Display (AKA i1D3) and noticed the previous calibrated profile using Spyder 3 actually did more harm than good. i got offered a discounted upgrade plan from Datacolor to upgrade to Spyder 4, i almost pulled the trigger, but bit the bullet on the more expensive i1 because all the colormeter/spetro meter reviews i read comparing all the popular colormeters in sub $1000 all unanimously preferred the i1's accuracy. so i bit the bullet. in fact, most pros who have limited budget all agree that the i1Display Pro + i1Pro combo is the minimum requirement. but the trouble is, the i1Pro is $1200. and since i1Display Pro shares the same hardware as i1 Colormunki Display, i decided just go with that. again, since i have no way of measuring against a benchmark, since i don't have a $28,000 Minolta CS-2000 that the Cnet guys use, not even a $1200 i1Pro. i can only take the Pro's words for it.

Ah yes Crysis must of been the one. I couldn't recall what game did it, just know I noticed it before.

These days though, most popular TVs and Monitors have threads upon threads of settings and profiles you can use instead. Usually it gets you "close enough" for those that don't want to invest in buying a colorimeter.

And I only got the Spyder because it was readily available locally. I couldn't find any stores that had the Colormunki stuff.

Post Re: HDTV/Display Calibration thread
i actually have a different point of view on those settings. those settings shared by users are just settings that you can plug in. but from the TV's and Monitors have owned and calibrated before, i've learned that panels can vary greatly even within the same size and model. even for the same size and model different review sites came out with vastly different pre-calibration results. the only way you're going to get a consistent result across the board is if two person bought the same tv from the same batch, same month, and same factory. even then every user will be outputing from a different source and equipment that all have different video characteristics. i have been an active member of the ES8000 thread on the AVS forum, and have tried various settings that others provided base on other's calibration, but without actually calibrating your own, they're just settings for you to plug in, and it's a crap shoot. a good example is someone setting from the same size from the same model can yield the same results as factory setting, or worse. i think some of the best results i got from other's settings were somewhere in the delta E 20, which is on par with the results i got out of the factory setting, but the same settings were within 3 delta E for the author.

i really really really discourage people from pluggin in other people's settings, you're actually far better off leaving it at factory setting than trying other people's settings.

Post Re: HDTV/Display Calibration thread
Samsung has always been known for "panel lottery" though. Not sure if they've resolved that recently or not. The settings I got off AVSForums for my Sony R550 looked noticeably better and when I put the Spyder4 on it with HFCR, I couldn't get it any closer.

Likewise, I've found TFT Central to be pretty close as well with my Dell IPS monitors, but self-calibration did make it a bit better.

So I guess it's hit-and-miss. I've had success, you haven't. 50/50 so far then :P

Post Re: HDTV/Display Calibration thread
monitors in general are easier to get a consistent result, because you're not dealing with all the added features of what modern tv's come with, not to mention when you get into large panel size over 40", the quality control becomes extremely difficult to produce consistent panels across the board.

you might have had a pretty good result plugging in other people's setting, but it's still a crap shoot.

would be interesting to see what your current readings are in HCFR. after all, that's what this thread is for ain't it.

i ran a full saturation sweep last night and found 75% and 50% and below were off, despite 100% primary and secondary were spot on. i did a bit more fine tuning in CMS and was able to get most of them line up pretty well within 2 dE. all except for green, which was pretty difficult, was only able to get roughly 3dE.

was able to fine tune it more last night and bring the dE from less than 3, down to less than 2 dE.

I can't even find enough time or patience to tweak settings to this extent :P

that's because i am starting to get on my wife's nerves. last night i had to wait until she went to bed and quietly did the calibration, took me two hours, didn't hit the sack until 1:30am.

that's when you know you're a tech junky, you have to sneak stumble around in the dark at night behind your wife's back.
