It would be great if the smartphone screen at 9:18 was projected on a 9:21 PC monitor

　The screen of a smartphone that is getting longer and narrow.The main terminal "LG V30+ L-01K" purchased two years ago has a vertical ratio of 9:18 (that is, 1: 2) and is quite narrow.These vertical screens are convenient for web browsers and chat apps that are often scrolled vertically, and the advantage is that if you put them horizontally, you can almost display a movie like a movie on the full screen.

　However, I want to see videos and games that I want to watch on the horizontal screen, and e -books like comics that can be seen in vertical scrolling, as much as possible, and I want to see them more comfortably.So I came up with a method of using a wide 21: 9 monitor for recently purchased PCs to enhance the working environment from home.If the screen of the smartphone is projected on this, the aspect ratio will be close and it will feel good.

　There are several ways to display the Android smartphone screen on an external monitor.One of the relatively simple methods is to use a cable that converts from a USB port to an HDMI output, and the other combines a smartphone "screen sharing" function and Windows 10 wireless display function.How to display.

　So, challenge right away.First, if you try a method of outputting HDMI from the USB port, the screen of the smartphone will be displayed vertically in the center of the wide monitor.Then, if the screen rotation is turned on on the smartphone side and placed horizontally, it will be reflected almost throughout the wide monitor.Since the wide monitor is longer than the smartphone, a little black band remains on both sides, but here is as expected.

　If you are in a horizontally placed state, you can display two pages of spread out large enough when reading a comic with a Kindle app, so you can read it comfortably.If the smartphone side is 21: 9, it seems that 4 pages can be displayed on one screen (there will be no such display method on the app side, so it is not something that is not).

　However, even if you want to display a web you want to display vertically or to display a comic app that can be scrolled vertically on the entire monitor, it is not possible with an HDMI connection.Unless there is a function to switch vertical and horizontal display on the monitor side, unless it is, vertical placement can always be displayed only in the center of the screen.So, as another method, I decided to use the "screen sharing" function.

　Even if the screen sharing and the functions of the Windows 10 wireless display are combined, basically, the same behavior is the same.If you try to display copyright protected content like distribution videos and e -books, the screen will darken, so the desire to display videos and comics will be large, though ...Well, I tried to think that if you set the "vertical" display in the Windows display settings for the time being, you should be able to display the website etc. vertically.

　The smartphone screen has been displayed very small.Apparently, it seems that it is displayed vertically in the area displayed in the original "smartphone vertical, monitor horizontal placement", and at 90 degrees rotated.It is an output style that no one gets, with a screens that are not much different from a smartphone in a wider monitor.

　I thought it would be because it would not be compatible with the Windows wireless display, so I tried to use an app "AirDroid" (USB connection) that can also reflect the smartphone screen wirelessly.The smartphone screen is displayed in the window of the Windows application, so if you maximize it, you should be able to display it on the entire screen ...

　I thought so, but even if the full screen was displayed, the window did not fit well throughout the desktop, and it was not possible to resize in detail.The resolution seems to be kept low, and the noise and blur are noticeable, so it has become a result that can not endure practical use.

　The author is looking forward to the release of Fujitsu's 5G smartphone "ARROWS 5G F-51A", which has an aspect ratio close to 9:21 on this monitor, but is it a little better screen display?I think today.It will finally be released at the end of July, and I hope that you can experience the serious mode of Fujitsu after a long absence.
