Broadcast Monitor Color Calibration

Hey everyone,

Do any of you have any advice on calibrating broadcast monitors other than calling in a technician? I've been trying to research for a lower cost solution, but I can't seem to find anything. Any product suggestions / general information would be greatly appreciated.

I also wanted to ask about calibration equipment. Does anyone have any recommendations on probes or calibration software?

Thanks,
Aaron

Well this prompts the question of what monitor?

I have a JVC DT-V24G1Z that I'm coloring on and a Panasonic TH-50BT300U as a client monitor.

I recently got my JVC, similar model, calibrated by a professional for a small fraction of what I was able to determine were "acceptable" calibration tools. Even if you do both monitors, I would suspect your time and money are better spent having someone who knows what they are doing provide this service.

Isn't that why your clients go to you?

There are a few issues to consider.
Firstly monitors change as they age. So you need to regularly re-calibrate to ensure they are accurate.
We have a Sony Grade 1 HD CRT and that is calibrated before each serious grading session and also every few weeks as a regular check. (CRTs need more frequent calibration)
We use a Sony probe that connects to the monitor and runs it's own calibration process but you still need to set a number of other variables manually. And ultimately it's an engineers eye that does the final tweaks to ensure it's right. This is because the space the grading is done in will affect the "look" of the display. So even with a correctly setup grading room there will be some inherent display offset needed.
As you can see from above this isn't an easy or cheap process but then spending a lot of time and cost grading to an incorrect reference is a waste of time and money so it depends how important your time and work is.

If all you are trying to do is white balance the cuts and gains, select the right gamma and color temp, you can easily do this yourself (affordably) and maintain these two monitors on an ongoing basis or before color critical work as Pat Horridge suggested.

Hi, has anyone knows the problem with the Hp Dreamcolor? I bought a year ago the new hp dreamcolor calibration System that replaced the old one that looks like a white mouse.

I was able to calibrate the monitor two times. And I don't know if this is has something to do with it, but I updated the OSX ML to 1.8.5 and now the calibration software doesnt recognize the monitor via USB. I updated the software's driver but nothing came up. The last actualization is for 1.8.2

anyne with the same trouble? Any suggestions.. there;s no way to camunicate this to HP

Best regards.

Did you try connecting the computer to the monitor via USB and then connect the calibrator to the monitor via USB? You can't connect the calibrator directly to the computer.

Thanks for your response. An yes, I always did it that way.. Monitor to computer USB , calibrator to monitor USB. AS the manual says..

any other trick?

Lightspace CMS and the best probe you can afford would be my advice.

I originally bought Chromapure to calibrate my projector (which has it's own CMS) but I had to bend the curves pretty far out of shape to get close to calibrated. I had it calibrated by a pro (using chromapure) and he did a lot better than me but in the end felt that it wasn't close enough.

After using Lightspace I feel confident that we have a truly calibrated system (there is also a FSI monitor in the room calibrated by Lightspace and they look identical) which is what were after.

I have recently calibrated my 46 inch LG plasma TV which acts as the client monitor in my Da Vinci Resolve suite. I have used Spyder4TV for calibrating, with good results. The primary grading monitor of my system Dell UltraSharp and its calibrated with Spyder4Elite. I could never eye match the client monitor till I went for TV calibration with the Spyder4 designed for TV.
Now, here is a small catch. The Spyder4TV calibrator works with the Spyder probe measuring colour, etc, from a dvd which needs to be run from an external dvd player. However, the calibration that it provides, did not match with the Resolve output (through my Intensity Pro card). Probably the Intensity Pro card has different colour rendering than a normal DVD player. So I had to resort to some tweaking. I grabbed the pictures from the DVD provided by Spyder, placed those pictures on a Resolve timeline. Then followed the calibration procedure of Spyder. And Voila, my grading monitor and the client monitor looks the same now!
