Customer reviews from Japan:




Cospa Yoshi
There are various adapters for connecting 4K from USB, but I think that the most cospa is good. I do not try to play the game, so I have not tried the limit of speed, but I can use it at all at document creation etc. However, it will take some time for the USB to start up at startup, so be careful about that. If you want to see the status while the PC is running, you will need to use the normal display port.




For WQHD monitor
I bought it for outputting to the WQHD resolution monitor with the HDMI port of the laptop computer being able to output up to full HD only. Although it is used in Win 8.1, it works perfectly. I am satisfied.




cintiq 16 pro 4K connection
When writing the review of this item last time, although 4K display was able to be done but it was written that the touch function or the pen does not respond, I will correct it 4K Before connecting Wacom After installing the driver and reconnecting it again, the touch function and the pen will now respond! ! I do not install drivers securely I wrote a review I am very sorry Very good product!




Driver
Used on the third generation monitor on the win7 desktop machine. After installing the driver from the CD, triple monitoring is realized easily when connecting the monitor. The price is also cheap, and this is good.




Compact and stable connection
The usage was easy, I connected it to the monitor and used it as an extension of the personal computer screen. Also use it when watching drama on TV using mirroring function. It was compact and stable when connected.




Easy to use
Recently thin notebook PCs are troubled omitting output terminals to wired LAN and external monitor. I switched to this model because my display has lost VGA input
