Elecom's ultra-compact 3-port HDMI switcher ``GM-DHSW4KP31BK'' review that also supports 4K / 60Hz output of PlayStation 5

Even if you want to connect multiple game consoles or media players to one TV or monitor, if the number of HDMI input ports on the TV is small, you have to plug and unplug the HDMI cable every time you play a game. Also, it is troublesome to switch the input signal of the TV or monitor one by one. In such a case, it is convenient to use an HDMI switcher that can combine multiple HDMI inputs into one and switch to HDMI output with a single button. The HDMI switcher `` GM-DHSW4KP31BK '' that appeared from Elecom is compatible with PlayStation 5 (

PS5 ), which allows you to play games at 4K / 60 fps . A reader sent it to me, so I actually used it.

The package of GM-DHSW4KP31BK looks like this. 'PS5 / 4 compatible' is written on the upper left, and PS5 compatibility is appealing.

The contents are GM-DHSW4KP31BK main body, remote control, power cord, manual.

The exterior of the main body is made of metal. It has a black, matte texture and is cool to the touch.

The size is about 5 cm deep x 8 cm wide. 'ELECOM 4K (60p) HDMI SELECTOR (3port)' and '4K 60p HDR' are written on the top.

Height is about 2 cm. On the front is an infrared receiver, an LED indicator that indicates HDMI input source switching, a power LED indicator, and a select button. The indicators indicating switching are 'INPUT 1', 'INPUT 2' and 'INPUT 3' from the left.

There is one power port and one HDMI output port on the right side.

There is nothing on the left side.

There are 3 HDMI input ports on the back. However, note that the input port numbers are 'INPUT 1', 'INPUT 2' and 'INPUT 3' from the right .

The product number and serial number are written on the sticker attached to the back.

The actual weight was 106 g.

The infrared remote control looks something like this. There are two types of HDMI output switching buttons, the upper one is a button to directly specify the source and switch, and the lower button is to switch back and forth according to the order of the sources. For some reason, the button to switch by specifying the source is arranged in a mountain shape, '2', '1', and '3' from the left.

An insulating sheet is stuck in the battery part of the remote control.

The button battery required for the remote control is CR2025.

The length of the power cord is about 140cm.

The output is 5V x 1.0A = 5.0W.

Insert the power cord into the right side of the main unit.

The input source switching and power indicators on the front lit up.

Next, insert the HDMI cable into the HDMI output port. This HDMI cable is Elecom's

Ultra High Speed HDMI standard cable that supports 8K video transmission , and is for connecting to a monitor.

Then connect the Nintendo Switch, PS5, Xbox Series X HDMI cables to INPUT 1, INPUT 2, and INPUT 3 of the HDMI input ports, respectively. The indicators on the front are 1, 2, 3 from the left, but the input ports on the back are 1, 2, 3 from the right, so be careful about the order in which the HDMI cables are inserted.

The GM-DHSW4KP31BK is now ready.

You can see where you actually switch the HDMI input in the following movie. When you press the switch button on the remote control, the indicator on the front switches properly, and the screen switches with a lag of about 3 seconds. PS5 is playing '

Call of Duty Black Ops Cold War ', Xbox Series X is playing ' Insects: Xbox One X Enhanced Experience '. Until now, even if I tried to switch the PS5 by connecting it to an HDMI switcher, it could not be 4K or HDCP was lost and it could not be displayed, but with this GM-DHSW4KP31BK, I was able to switch without problems. There is no problem with the sensitivity of the remote control.

The GM-DHSW4KP31BK's size is so compact that it can easily be stored under a TV or monitor. However, since the input port is on the back and the output port is on the right side, the cable and the main unit are L-shaped as shown in the image below, and in some cases it may be difficult to organize the wiring around the TV. I have.

Also, I felt that it was a little confusing that the order of INPUT 1, INPUT 2, and INPUT 3 was different depending on the indicator display, the input port on the back, and the button layout of the remote control. Still, as written on the package, it can be switched with PlayStatino 5 without any problems, and it can be said that it has sufficient performance as an HDMI switcher.

Elecom's GM-DHSW4KP31BK has a standard price of 10,648 yen including tax. It is also handled by Amazon.co.jp and can be purchased for 6040 yen including tax at the time of article creation.
