Calibration with Spyder5 and HCFR gets far to reddish ?!?

I did the calibration with following setup:
HCFR running at a Windows Laptop with an "Spyder 5" and latest HCFR Software.
Sat-Receiver that can play images with grey scale images 0...100%).

I did the initial reference measure (see picture). Spyder tells me it is far to blue and to less red. Although I think it is not to far away from beeing neutral I know that eye is not a good instrument for color. So I adjusted the 90% as example to be neutral. But - suprise - the image at TV is reddish.

I have no idea what might go wrong. Is my colorimeter damaged? What chances I do have to debug this. White paper is not reflecting. Something else that I can take as reference to check the colorimeter?

In setup is a calibration of Colorimeter mentioned, but don't know how to do and where to get data from.

And, second issue: It seems that gamma is extremly low, can this be true?

Thanks, and especially for the developer and community for this great tool.

It may be the Spyder5. Every Spyder meter before the newest SpyderX is not recommended as many tend to not be very accurate.
Read our meter FAQ here: http://www.curtpalme.com/forum/viewtopic.php?t=11436

How old is your Spyder5? How was it stored? If it's old it may also have drifted.

It is from 03/2016 - so 3,5 years and has been already in its original package.
I can imagine a slight drift over the time, but such a massive one -so that it is visible? Strange.
If you have some experience - would it be typical that red fades and blue gets stronger...[

So, to summarize: You can't see that I am doing something wrong? That colorimeter gets some faked data?[/list]

5 years is pretty old. How these drift is anyone's guess - they do not drift in the same manner. I don't know what, if anything, you're doing wrong. Sorry!

OK, thanks anyhow. I just found the date on package, 03/2016 - so just 3,5 years old. Rather strange it should change so rapidly and fast. We use color sensor chips in our products and never heard the Bayer pattern would change so rapidly. These products are in use for more than 10 years and are in harder environments.
Ok, it doesn't help to blame on this.

I don't know if the issue is (a) due to drift or (b) the meter not being overly accurate to begin with, or (c) both, or (d) an issue with the software or how you're using it. I only point out drift as a possibility.

No, that's ok, you can't see it from distance Wink.
As I understand this, a calibration on Laptop's screen (which affects Laptop only) can not have an effect to the TV (which is not connected with laptop).
The only what might happen is (unlikely), that the PC knows it does some calibration and think it has to take this into account receiving data from Spyder. Software can't does spyder reads data from own (calibrated) laptop monitor or from external TV.
The other thing that comes to my mind is, that Spyder has to be loaded with some driver/init data which might fail. Not sure how installation of Datacolor's software, DisplayCal and HCFR and drivers interfere.

I used the same Spyder with DisplayCal, found the images are on the warm side, but the "white" was far away from being as reddish as if I try to get a neutral point here.

I'll try to organice a second colorimeter and will repeat that. But that can take a while. Thanks for your help!

Used a different Colorimeter from a friend, as Spyder3. Ok, not high end - I know.
But it ends up same.
I am doing the DVD manuell way and give the Spyder an Image created by Irfanview. There I can adjust the 3 color channels.
I achieve to get R G and B to same 100% level - but surprise - the image I created looks reddish. I mean not a "warm white" but a real rose.
So there is something wrong how I use Software - but there aren't so many things to adjust ?!?

So what I did: Say new, select manual DVD and Spyder3 instead of simulation. As I have no configuration file I skip it. Then I start continous measurement and adjust the image below the Spyder as described above.

It could be many different things.

You could be using the software incorrectly.
You could be adjusting the display incorrectly.
Your display could have a broken CMS (colour management system) - this is actually very common.
Your meter/software may not be profiled correctly for the display type you're using.

Think I found the issue:
Take a second laptop and the results seems to be ok (so no reddish for 100% at each channel). Than I connect Spyder to my laptop - same result. So it is not a installation/driver/spyder - issue.
Than I let the spyder look to my Laptop - same result as above.
So it seem that my Laptop screen is so strange that calibration fails (for some reason). Mh - ok it is a very bad screen, TNT. Of course results are very dependent on viewing angle. But ... I can rotate it to each position - it never happens that a sensor calibrated image (reddish) looks grey.

So, it keeps not understanded isse: Somehow spyder is not compatible to my laptop screen (technology).

So the last point I mentioned:

"Your meter/software may not be profiled correctly for the display type you're using."

CHeers!

Is it worth buying Spyder5 if it works so badly?

I don't recommend any Spyder before the SpyderX.
Read more as to why on our SpyderX PRO order page:

I have already calibrated several screens using Spyder5 and was satisfied. First, Spyder5PRO measures the ambient light in the room using its ambient light sensor on the top of the device. While Spyder5PRO creates settings, measuring the illumination in the studio or at the shooting location, do not move away. If you block the light, you need the sensor to fix it. You may not have honored some calibration steps, so it gives out redness in color. By the way, which version of Windows are you using? If the version is unlicensed, it can also negatively affect the program's operation. I advise you to purchase an official key because it provides all the features of Windows 10 Pro.

Quality of the results depends on what you're measuring and how your specific unit is in terms of accuracy.

For accuracy, unless you measure it against a known good meter, you don't know how accurate it is. Every unit will be different. In other words, if you measure one unit and it reads reasonably accurately, it doesn't mean all units will. They will not.

The other issues mentioned on the link I provided above is that it has poor low-light performance and is not ideal for projectors: The SpyderX is somewhat limited for those who have projectors. See here for complete details: http://www.curtpalme.com/ChromaPure_SpyderX.shtm

This is why our recommendation is if you never plan on calibrating projectors and want a slightly lower cost open to the Display 3 PRO, the SpyderX PRO is the meter for you. If you're a serious enthusiast or a professional, look at the Display 3 PRO as your entry level model for only a few dollars more: http://www.curtpalme.com/ChromaPure_SpyderX.shtm

Note that I'm talking about the SpyderX PRO, not the SpyderX. This is the more accurate model done through our profiling. Again, details here: http://www.curtpalme.com/ChromaPure_SpyderX.shtm

Cheers!


Kal
