I found this when calibrating two session, I got two identical color checker reports - 100% identical data (I mean data sheet) which I believe is impossible. Seems like *.xls are locked and filled with your session data....

Also, I started new session, I have deleted checker.csv and without any measure I run checker report from CP. I got report filled with the same values as above...
This problem occurs if you run the report with Excel already open. Just make sure that Excel is closed when the report is run and the data will properly update.

well, I asked this same question in the official madVR thread on the Doom9s community and there I was told that WTW and BTB SHOULD clip

You have basically three options:

1) Set madvr to pc levels, set gpu to pc levels, set TV to pc levels (0-255). This means, that BTB and WTW will be clipped, it also means that there is expansion involved, which might lead to banding. madvr dithering does a good job of eliminating that.

2) Set madvr to TV levels, set GPU to pc levels, set TV to TV levels. This means there will be neither clipping nor expanding.

3) If your TV doesn't have settings to change black levels and is fixed to TV levels.: Set madvr to PC, GPU to TV. BTB and WTW will be clipped, and there is double processions going on (expansion by madvr -> reduction by gpu).

The second option is the best quality wise, because there is no processing of the levels involved, and therefore no banding introduced. The problem is that if you use your PC for anything but viewing through madvr, your levels will be messed up.

For that reason madshi recommends using PC levels throughout if you do anything other than watching videos, and the second option if all you do goes through madvr.

see monvo's nice summary above and use option 2 (madVR = (16-235) TV levels) if your display is used solely for video.

There is also a 4th option if you want both limited(video) and full-range(pc applications) to display properly. If you can adjust input mapping on your display (usually low or limited vs. normal or full) then use option 2 and switch display input to normal when displaying desktop applications.

Lumagen Radiance XE/XE+/XE3D/XE/XE+/XE3D/Mini-3D/XD/XD3D + Radiance 20XX Series (2021, 2022, 2041, 2042) New 102913 Firmware Update

Release Notes

Added 2 APL patterns to the Gray Window pattern group.

Added a custom window size and a custom window size + APL pattern to the User Color window pattern group.

The 2 new patterns added to the User group use the RGB level that are settable in the first 3 patterns.

The custom sizing allows setting the window size in .1% steps.

The custom size + APL pattern allows setting both the window size and an APL.

As you vary the size of the window the background level is adjusted to give the desired APL.

If it can't meet the requested APL, a greater-than or less-than sign is displayed next to APL to indicate this (.ie setting RGB=240,240,240, the custom size to 90.0% and the APL to 30% would give the greater-than sign next to APL).

Added rs232 access to the new patterns.

The rs232 format for the new User size pattern is "ZY7TsSSSRRRGGGBBB" with SSS being 3 digits (000-999) for 0-99.9% area of screen.

The rs232 format for the user defined size + APL pattern is "ZY7TsSSSAAARRRGGGBBB" with AAA being 3 digits to be set to 000-100 for 0-100% APL.

Just a thought...
If would be very nice indeed if we could get APL patterns support in the built-in pattern generator in Chromapure as well. I can't see that being too hard to do as it is all generated images via software.

In this Day and Age it's almost impossible to buy any electronics that work as advertised. I will have to give Tom a pat on the back. I purchased Software and a Accupel DVG 5000 from Tom, and for the first time in a long time I felt like I got exactly what I paid for and then some. I do like to make purchases from individuals and companies that support our forum and as we all know Tom goes way out of His way to Help us.
I just wanted to take a moment and say Thank You for the product you sell and the continued support you give to this Forum.

Question about laptops to use with Chromapure:

I only have Macs in the house for work and family. However, as we know the Chromapure software is made for PCs/windows. I was thinking first of buying some software to get my mac to run PC/windows programs to use the Chromapure. But now I'm considering biting the bullet and just picking up a cheap PC laptop.

So my question is: Are there any particular technical requirements I need to look for in a laptop? Will the Chromapure calibration (and I intend to use autocalibration when possible with my new Lumagen) go any faster or slower depending on what laptop I buy?

I'm looking to spend as little as possible on a laptop, as long as it has the sufficient specs for Chromapure.

Thanks...

Hi, I am in the same position - would love a Mac version but it doesn't look like one is due soon.

One option I have been looking at is CrossOver where you can run certain applications which have been ported over by the developers (they then run under a virtual OS - you do not need Windows installed) . It seems you can either pay them to do this or they do it if sufficient people vote for the application to be included. Chromapure is on the site so if you have CrossOver (I think the trial version gives you a vote) it may be worth taking a look and placing a vote! The link to the product page is here.

You can try an installation using CrossOver but it wanted .net frameworks and got quite complicated so I gave up for now. May be some others out there who know more on this than me though as to whether it is an option worth pursuing.

Users report excellent results running CP on Macs using Parallels or Fusion.

You can get a good PC laptop for about $500. I'd try to get a dual-core processor and 4GB of RAM.

ChromaPure requires .Net to run, so this is expected.

Yes, I have had good luck with Fusion.
post #4846 of 5348
And I've had good luck with Parallels. And I have not had to boot up in Windows.....Chromapure runs fine using parallels (under Mac OS X) with no communication problems for the i1D3 or the Lumagen Radiance.

I would suggest trying out VirtualBox as well. It is free and has been around for many years. Have no idea if there are any problems with Chromapure, but since it is free just download and try it out. I've been using it on my windows dev computer to create virtual instances of both linux and other windows for test purposes. Works great.

post #4849 of 5348
I just found a decent deal on an Acer laptop. Specs listed as: AMD A10-5757/ 500GB HDD/ 8GB RAM/ Windows 8. Should be fine I expect.

Though, I have to say, even though it was a good deal I had something of a "heavy heart" pulling the trigger on buying it. For a long time I've resisted this level of calibrating my displays myself because of, for lack of better word, the "technology fatigue" I've developed after years of this hobby. When I first got my plasma years ago I spent way to much time looking at "how it looked" and tweaking it instead of actually enjoying movies. Then my home theater build was 3 years of techno-hell. I finally got down to just forgetting the technology and just enjoying movies on my system over the last few years. Watching the threads on calibration...the enormous learning curve and the sheer amount of time and energy it seems to take seemed about the last direction I wanted to go. But...I also want to have my projectors properly calibrated; I'm used to a calibrated image.

I started down the road to doing my own calibration mostly on the grounds that it was such an expense to have my projector calibrated each time I bought one, and that, not having been able to find a reputable calibrator here in Toronto, I was driving the darn things across the border for calibration. So I bought the Chromapure package (seemed most user friendly) and a Lumagen (hopes of auto-calibration to reduce time spent calibrating)...and now a laptop to run the program.

But then I recently bumped into a very experienced calibrator who works in Toronto. I was doing the math in my head as I was paying for my laptop today, and I realized that the amount I've spent just on getting set up to do my own calibrations would have paid for around 7 years of professional calibration (once a year) for my gear, or if I followed the same pattern of calibrating only upon buying my projector (once every 2 years), 14 years of calibration! By someone with more accurate gear and who knows much better what he's doing.

I'm not sure, yet, I've come out ahead on this or made the right move.
post #4850 of 5348
It never is about coming out ahead. I have never come out ahead Finacially chasing the Holy Grail of Video Bliss. It's about just what you described in you post. I don't have any Calibrators in my area and If I did I'm sure they wouldn't go to the length's that I go to, for the Video perfomance and Sheer Anal attempts of trying to make it better. Hell even some of the greatest Calibrators on this forum continue to Say if it's below 3 error it not human perceivable. One of them even told me what is it about beyond Human limits that you don't understand.
It's all about some of us like for our Displays to operate the best they can. I figure if I can get it below Human limits that just cancels out some of the error's in my Equipment. All I can do is Hope those error's are in my Favor.
This is a great hobby once you get the hang of it, and once you do, All that buyers remorse will just be Joy.

Hello, Check this example, dE 1-3 differencies are easily visible, it has to do with the color, but think that your are measuring only 6 colors of the 10 Million possible colors.

Lumagen Radiance XE/XE+/XE3D/XE/XE+/XE3D/Mini-3D/XD/XD3D + Radiance 20XX Series (2021, 2022, 2041, 2042) New 112513 Firmware Update

Release Notes

Fixes audio issues seen that could give noise or no audio with some equipment.

Added a shorter option for audio mute length under Input: Audio Setup: Mute Control. The default is mute length is "Long" but options include Short, Medium, and Long. Previously, the options were only Short and Long which have now become the Medium and Long values.

Several small menu improvements and fixes.

Small improvement in input switching speed.

Is there much significance to the contrast ratio figures that appear at the bottom of the calibration report? I ran a fresh calibration yesterday and my contrast before was about 14,000 and after 2900. The picture looks good to me and as I manually calibrated the greyscale/gamma I know I've not done anything that would raise the black floor (the peak white readings were very similar pre and post calibration).

I've already attached the report to the X35 thread today, so don't think I can attach it again.

Release Notes

Fixed up an older bug (recently made worse in 112513) which depending on equipment and settings could intermittently (or regularly) result in delaying turn-on of video output. Could be double normal output turn-on time and feasibly even longer.

Bugfix for issue created in 112513 release causing an output to not turn on if only one output is connected.

Thanks Tom...nothing wrong with the result that I can tell, I just wondered at what point it does the contrast measurement and whether it's even significant anyway?

post #4859 of 5348
Checked it again last night: I think it's down to meter sensitivity measuring the very low black levels off the screen: It was very variable when measured off the screen (possibly due to my laptop screen effecting the reading) so I measured from the projector instead. This gave a contrast on/off result of 31,000:1 with the X35 iris at -6, Isco lens in place set up and calibrated for 2.35:1. This seems a pretty realistic value for an X35 so I'm happy with that. I've confirmed that 0% and my projector set to 'hide' show no visible difference in black level, so I'm also happy that nothing has raised the black level in terms of settings in the Lumagen CMS as I had initially suspected might be the case.

I also took the time to recheck the 15,10 & 5% greyscale/gamma points as it was much easier to take readings of these with the sensor facing the screen. I may be fortunate with my screen as there seemed to be very little difference in the white balance reading (other than light level of course) between reading off the screen and reading directly from the projector at the screen when measuring 100%. This also helped to take away a reddish tinge to the darker greyscale patterns that was visible by eye but the 'from screen' measurement did not confirm, so I feel that dark areas are more accurately adjusted now. A side benefit being that the readings were much quicker too, so there wasn't that delay in making adjustments, to then seeing the results (and then watching them overshoot the target).

I may revisit the calibration and set up a reference/field meter to get it 100% accurate measuring from the projector rather than off screen. In this case would I leave the setting for the sensor at 'Front projector from screen' for both field and reference meters? Is it even possible to change this setting when configuring for a field meter?

I tested this last night thinking it was a bug in the software, but I couldn't reproduce the problem. You can take reference readings from the screen and then field readings from the lens. The diffuser in the D3 is quite neutral so you can get excellent readings without this, except of course you lose whatever screen effect might exist. For neutral screens (StudioTek, e.g.) this doesn't matter.
