I have another concern about the i1Display. I think the suction cups will damage my LCD screen, which has a coating on it to darken the blacks. It's an early generation Sharp Aquos ( that I love, dearly ). I might tape the suction cups up, that might harm the calibration result, so I'm beginning to feel that I bought the wrong calibrator. I should've gone with the i1 Pro, even if it costs more -- to protect my TV AND get better results.

I value my television. And I'm extremely happy with my DVE / color filter results. Maybe this whim to see how much better the picture can get might cost me more -- such as unremovable suction cup marks in the middle of the screen.

A few days ago, I asked you how to calculate the Y values for the secondary colors, but you and Tom said that it's probably unecessary. I'm going to give it a try if I keep the i1 Display. But I'll just use the same calculation process you used with the primary colors. For instance, for yellow, I'll match it's Y value to 92% of the white's Y value (I don't remember the reference chart numbers ). I hope that's okay. If it's not, please let me know.


You know, I'm very happy with my DVE / gel filter results. It's too risky to use the suction cups on my beloved LCD screen. I might just go ahead and change the order from an i1 Display to an i1 Pro. One professional isf calibration session is already about $200. Considering that you'd have to recalibrate your television almost yearly, the i1 Pro isn't that costlly. If you know a workaround for the suction cups without harming my television, please let me know. It would be cherished information.

And I appreciate the attention you've been giving me lately. I have been trying to get the perfect calibration for almost a decade now, finally deciding to own a colorimeter. I might've hit the perfect callibration sometime ago, but I never knew it. In the past, it was easier to calibrate a television. I'd just pick up a video game box, look at the screenshot in the back, and then pause the game screen at that same screen shot. From there, I'd adjust my colors until the picture looks identical to the game box screenshot. And then I'm happy. That was with the old CRT televisions. Now with the C.M.S menus, I'm getting maybe too obsessive about achieving accuracy, as the directors intended.

Hi,

I'm not sure the meter will cause damage. Seems unlikely but you never know. You can maybe get away with simply not pushing it on hard or pushing it on at all or tape/flatten/cut the suction cups. Keep all the other lights in the room off.

$200 for a calibration is pretty cheap if you ask me.

P.S. I've split this post into its own topic since it didn't really have anything to do with the original sticky thread of colour accuracy.

I'll test the cups on a computer LCD monitor. There should be marks though, because the white paper dust cover attached to the colorimeter during shipment has suction cup marks on it. X-rite probably coated the suction cups with oil to provide stronger suction, and that's probably what's causing the marks on the paper.

Right now, I'm considering these options for the suction cups:

1) Make a clear suction cup cover out of maybe syran wrap, static cling glare filters for smartphone touchscreens, or a black matte paper. But these materials might contaminate the colors entering the colorimeter.

2) Buy those greyish eraser gums. They're like playdough or putty for erasing pencial marks. Then, I'll stick one on each suction cup. But becuase they're pliable material, I think they might contain some water / moister, which would degrade the colorimeter.

3) Take a pin and poke a hole n each suction cup. Because suction cups need a vacuum seal to provide the suction, a small hole should prevent suction. Then, I should wash the cups from the oils that I'll assume X-rite adds to the cups to provide a better seal. But this method might contaminate the colorimeter with dusts and debris, since I would work on the colorimeter itself, rather than just sticking something onto it.



Maybe tomorrow, on the weekened, I'll start the calibration. We actually met decades ago, when I was searching for a television and found your greyscale guideline. Too bad it took me this long to finally give it a go. Let's see how the results turn out, if I can get myself to protect my TV from the suction cups. (The TV doesn't tilt upwards, so I can't use the gravity method).

Good luck! Let us know how it goes!
