In our industry we are dealing with displays, and our goal is to ensure that the product we are working on is delivering the greatest on most arcuate picture possible. If you find any tips or tricks when it comes to calibrating please feel free to submit them to us and we can post them in this section! Here is an except from Jason Dustal about Calibration:
"In years past, there were only a handful of adjustments that we were concerned with. Getting to the adjustments was the hard part. Today, we can easily get to the adjustments, but there are many more adjustments. Let’s take a look at a recent system that I calibrated for a client.
He has a 65” LG E6 OLED in a room where the lighting is 100% under his control. Most of his content comes from either an Oppo HDR Bluray player or a cable box. Some material he watches is in standard definition, some is in 1080p high definition, some in UHD (4K HDR). His room can be as dark as a cave or as bright as a sunroom. When it’s movie time the room can be black, but during football on Sundays when his friends are over the room can be bright. He has three theater seats in the room. His seat is dead center to the screen, but the other two seats are at a slight angle. The TV has the ability for a “day” and a “night” picture mode. This allows for maximum performance regardless of the room lighting. TVs traditionally have two adjustments for white balance; this model has two AND 20. Most TVs have two adjustments for color; this model has two AND 18. In this situation, the TV has upwards of 80 possible adjustments. Luckily he doesn’t care about 3D or that would have been a couple dozen more adjustments!
That’s just one of the two (day/night) modes.
I also have to consider the viewing angles from the other two seats and all of the advanced settings in the Oppo Bluray player. Oh, and the cable box? That has settings too. Luckily in this case, the video was not passing through a receiver. If it had been, I would have had to calibrate the video portion of the receiver too!
That’s just SDR (standard dynamic range).
Now we are finally getting a handle on calibrating the HDR (high dynamic range) mode in the TV. This opens up a brand new can of worms. Once the TV receives an HDR signal, it has a completely different menu for picture settings. Yep, you guessed correctly, now there is an HDR “day” mode and an HDR “night” mode! By the time I was finally done, I had about 5 hours of work poured into his system.
On top of that, we are dealing with multiple types of HDR. For example, calibrating a Samsung in the HDR mode is very different than calibrating an LG in HDR mode. Just figuring out the TVs menu structure and what the manufacturer names all of the different settings can be a time consuming task.
Can we use our old calibration equipment to calibrate new TVs? NOPE! With the introduction of 4k resolution and HDR, all of the calibration equipment has to be updated. Will my UHD equipment last me the rest of my life? NOPE! It’s only a matter of time before we see displays with 8k resolution at 120hz. I will be upgrading equipment for the rest of my career!
One question still remains: why didn’t they optimize the TV’s picture at the factory? The answer is the same as it has always been. The manufacturers are very good at what they do, but they have no idea what room the TV will end up in, what components will be feeding the TV, where the end user will be sitting, or what they will be watching. Calibration has and always will be a custom service. In the 9 years that I have been calibrating, I have learned one very important lesson. Every system and client is different, but we all are trying to achieve the same thing: the most accurate image possible!"
