The problem that the resolution is half with 4k120p input.I asked 5 TV manufacturers -AV Watch

About a year since the launch of new game consoles such as PlayStation 5 (PS5) and Xbox Series X.From genres such as TV, AV amplifiers, and sound bars, products that support the same “HDMI2.1” as game consoles have begun to appear.

Specifically, the television supports HDMI2.1 from Sony Bravia, Panasonic Viera, Sharp Aquos, Regza, and LG middle 2021 models.Denon, Marantz and Yamaha also supported HDMI2.1 in all models in 2021.

Finally, for users, the environment has been set up to play games by making full use of the performance and functions provided by the latest game consoles, but on the other hand, there are HDMI2.1 compatible TVs for domestic reviews and overseas AV media.The event was pointed out.

That is, "If you enter a 4K120p signal on the TV, the vertical resolution will be halved."

If it is a television that claims to be “4K120p compatible”, the signal of 4K/3,840 × 2,160/120fps should be displayed as it is, but some TVs have half the vertical resolution (only if the 4K120P signal is entered is entered.It is said that the original video has not been fully described, as it has been thinned to 3,840 x 1,080).* Normal 4K signals other than 120p are displayed without any problems

Is there really such a thing?

According to a technician from a television manufacturer, "The amount of 4K120P data is very large compared to the past, and the load on image processing is not small. It can be a way to give a refresh rate."However, there are no such details in the manufacturer's catalog, products on the website, support, etc., and word -of -mouth information, etc., "Company A and Company B are OK" and "No, Company B is half".Sounds complicated.

So I asked Sony, Panasonic, Sharp, Regza, and LG's five major television manufacturers, and decided to confirm whether the resolution would be halved with 4K120p input.
