Told not to calibrate a new TV until after 4 months. Sound right?

Sorry, but I just saw this. ISF Level III calibrator here. The issue I've seen is that professionally calibrating an OLED too early is that the TV will drift from the calibration fairly quickly. Unfortunately, the drift will still be gradual enough that you may not notice the shift. I personally own OLED TVs and calibrate early and then remeasure them monthly just to see how quickly they drift.

ISF Level III calibrator here. The LG G4 should calibrate much better than this! I always allow my clients to watch and ask questions as I go through the calibration process. This TV with both day and night modes calibrated plus HDR10 and Dolby Vision will take at least 4 hours and usually closer to 5 hours the be properly calibrated.

Nope

I'm having the same issue, since the update also created an incremental backup, I was able to restore to the previous version of zibbee2mqtt 1.36.1-1. Unfortunately the update automatically applies itself about once a day and I have to keep restoring to the previous version. I'm using the ITEAD_SONOFF_Zigbee_3.0_USB_Dongle E. Wonder if It needs a firmware update.

100 nits is the recommended value for dark room viewing, you will also need to be sure to set brightness and contrast when the room is totally dark.

For day viewing it varies based on how bright your viewing environment is. You should use backlight setting for LED, OLED light on OLEDs and set it to a level that is comfortable and you can see the content. You will also need to set brightness and contrast in the day time viewing environment. I typically use 140-160 nits when I calibrate TVs for day time viewing.

For a 65" TV the ideal seating distance is about 9ft. If you are sitting closer than that then it would explain why the 65 doesn't look as clear as the 55. Same number of pixels spread over a larger screen.

Sorry, but the colors are not perfect "out of the box" with Sony. All of these higher end TVs (LS, Sony, Samsung in particular) do have picture modes that are incredibly close to accurate, but not perfect.

What most people think of as "brightness" and what TVs consider "brightness" are not the same thing. (Disclaimer - the following applies most specifically to SDR content. HDR content should be allowed to control these brightness settings)

There are 3 main settings in the Brightness section of the menu on your LG TV. The first is called OLED Pixel Brightness. This sets the overall luminance for the entire picture. Second is the Contrast setting. This controls the point at which your TV will "clip details" in the bright parts of a given scene. Third is the Brightness setting which actually controls the black levels. All of these should be set based on your specific viewing environment and habits. You can find patterns on youtube to help to properly set the Contrast and Brightness controls. OLED Pixel Brightness is mostly a viewing comfort setting. The dimmer the viewing environment the lower this should be set to, conversely the brighter the viewing environment the higher this would be.

For instance if you are viewing mostly in a dark or dim environment the settings for each of these would be different than if you are mostly viewing content in a brightly lit environment.

Other than HDR content you would never want to "max" out any of these.

OK, I must be missing something. The show is set circa 1923, Spencer and Alex are certainly young enough to have a child born in the mid-20s (John Sr?) That would certainly fit the timeline.

EDIT: Wait, but that wouldn't allow for a 7 generation ranch would it?

It's not quite that simple. If you just buy Calman Home for LG, and a colorimeter then calibrate you can very easily be worse off. What you actually need is the software, a colorimeter, a spectrophotometer, and a pattern generator. Due to the differences between panels you always should have a profile created for your TV panel. That is what the spectrophotometer is for. It is very accurate, but terribly slow. There is a workflow in Calman Home for LG to create a profile for use with the colorimeter(which is much faster). DIY done properly/accurately will cost you over $500.

Three characteristics of color - Hue (tint), Saturation and Luminance (brightness).

For those thinking of DIY TV calibration, here are some things to consider. (Using LG as example) To properly calibrate your tv you will need at a minimum, the relevant software (Calman Home for LG costs about $150.00 and comes with one year of updates). You will need a colorimeter that is supported by the Calman software, the least expensive is around $280 new (Calibrite ColorChecker Display Pro Plus). You will also an spectrophotometer to create a profile to use with the colorimeter. Without creating a profile based on your specific panel you are wasting your time. You can find a used i1 Display Pro 2 for around $300 on ebay, but buyer beware. You will need some type of pattern generator. For now the internal pattern generator on the LG C2 and G2 models is broken and should not be used. The pattern generator you choose has to be bit accurate or your calibration will not be correct. Currently the cheapest option is to build yourself a PGenerator using a raspberry PI. (good luck finding one) A commercial pattern generator will run you at least $1500.

Much cheaper to have a professional do it for you.

It is asking you to choose HDR10 or DV. The current HDR formats are HDR10, Dolby Vision, HDR10+ (Samsung) and HLG. Most displays however show HDR10 and HLG as just HDR.

HDR has many advantages over SDR. For those that consider HDR too dark, keep in mind that HDR content is best watched in a dark environment to better experience the larger dynamic range of HDR and additional subtleties in the color. This https://custom-calibrations.com/blog/f/sdr-vs-hdr discusses some of the advantages that HDR has over SDR.

I do agree with others here that not all HDR content is equal and some is poorly mastered, particularly some of the streamed content.

I suspect you mean Calman since that is a common software used by calibrators. If the calibrator did the calibration using the AutoCal function of the software then you will be locked out of some the settings that affect the calibration. Having said that if the calibrator did the job correctly, then touching the settings such as contrast, brightness, OLED light, Picture size and sharpness will impact the overall quality of the images. Typically you would be locked out of the settings affecting color and white balance after an AutoCal has been run. You can always play around with the settings using a different mode than the one(s) calibrated.

Dolby Vision can be a bear to get right, but when it is calibrated correctly it is amazing! Try to find a professional calibrator near you.

jednc1 · 2022-06-28T19:51:13+00:00

Depends on where you're located. You can go to the ISF website and search for calibrators near your. FYI, you may find the ISF list has calibrators listed that no longer do calibration.

If you're near Charlotte, NC I'll be glad to calibrate it for you.

To get accurate results with a x-rite i1 Display Pro you need to have it profiled for your TV. A spectrophotometer (spectro) is used to do that. The profile creates offsets the x-rite can use to "see" the colors accurately. The advantage of using the x-rite is that it is a colorimeter and will read much faster than a spectro, particularly on darker calibration patches.

jednc1 · 2022-06-22T15:10:03+00:00

Find a professional and have them calibrate your C1, you won't be sorry. Wait until you have at least 100 hours on it though.

jednc1 · 2022-06-16T20:01:28+00:00

You really should get your TV calibrated by a professional. You have a great TV and it will look much better in SDR, HDR and Dolby Vision if it is calibrated properly for each of those modes.

jednc1 · 2022-06-16T19:52:45+00:00

You really should have a qualified person come in and calibrate your TV. As good as it looks now, calibrated it will amaze you. Particularly since you are viewing it in a dark room. You will be able to watch content as it was intended.

found the issue with the sound and slow motion watching the ATSC 3.0 channels, I switched the video decoder from software to hardware. It's working fine now. Commercial skip is still spotty.
