4K TV delay and consult! Introduced "4K Lag Tester" that can be measured with PC less

My series "Nishikawa Zenji's Large Screen Mania" is a longevity series of AV Watch, which has exceeded 18 years of serialization this year, but has released an unusual measured value that cannot be seen in the same series of other magazines.

Recently, it is a color spectrum measurement value.This was started in 2017, adopting it as a guideline for color reproducibility of TV products.There are many similar articles that show photos of digital camera photos of displayed images, but the shown photos are actually depressed in the SRGB color space, and the appearance of the camera itself changes, so the appearance changes.I can only convey the "atmosphere".

Large -screen ☆ geeks also show some reference photos, but just convey the atmosphere and do not use the photos for evaluation.By the way, "Reference photos in which two beautiful women are sitting in the GT-R seat" has been used for their permission since 2012.Don't worry, they are still the same beauty.

The longest measurement system is the input delay measurement started in 2010.

The first time was Toshiba's CELL Regza "55X2" (see the 136th time).The fact that the input delay was measured was that the number of questions from the author, "Please tell me which TV that is suitable for the game" increased.Certainly, from this time, in the industry, the recognition that the natural enemy of gameplay is input delay has spread, and conscious manufacturers have begun to "reduce input delays."

When performing the measurement, a reference television that publishes the HDMI distributor and the nominal name of the input delay, but from that time (and still), cooperating with Toshiba Regza, which has published its nominal value.I will have it.

By the way, in the early days of 2010, "19RE1" (1,366 x 768 dots/Nominal input delay 2).6ms), "26ZP2" (1,920 x 1,080 dots/Nominal input delay 3 from 2011.0ms) has been adopted as a comparison target TV.I have been using 26ZP2 for about nine years, but I have begun to think that it should be the basis for delay measurement when inputting 4K video input.

This method, which measures the reference machine and the measured TV side by side, is substantially a relative comparison, so it is necessary to disclose the nominal value of the input delay on the reference aircraft.And if the reference machine is large, it is inconvenient to handle the equipment at the time of measurement, so a model with a small screen size is desirable.

Of these two requirements, only Toshiba was asked to respond to the "announcement of the name of the input delay".I asked a manufacturer of an overseas gaming monitor not only as a domestic television manufacturer, but all the respondents were "let me keep them private."

In that case, it was likely to be Toshiba Regza this time, but as mentioned in the recent big screen ☆ enthusiasts, "40 type, the smallest size of 4K TV is an endangered species".Same for Toshiba Regza.As a measurement reference machine, the 43 -inch over was abandoned.

In such a trend, the advice received from the surroundings was "Why don't you use a rug tester that can be used with a standalone?"

Looking at it, it seems that some of the media in Europe and the United States have been adopted, and it looks pretty good.Well, in fact, it was clear that the measurement method so far was clear, so it is also true that there are no other options.That's why I decided to decide to introduce it.

I would like to introduce this rag tester as an extra edition for this "Nishikawa Zenji's big screen ☆ mania".
