Also, depends on what kind of DeX you are using. I used to using USB cable connect to my desktop, then talking with client on Buds Live, PC Desktop working on VPN RDC and DeX on PC adding Notes, reply email and whatsapp with friends.
Drag and drop files between phone and PC is fast and easy.
I personally like DeX on PC more than Wireless DeX. I found wireless DeX has some lagging and USB Mouse not working correctly.
Another option is using DeX docking. But don't want to bring docking and monitor with me all the time.
Above is my experience on DeX. Hope it gives you some ideas.
You can ace that research project by using a DeX Pad or a DeX Station. Both products are docking stations that your phone can sit in. With a DeX Pad your phone will lie flat, and with a DeX Station, it will be propped upright. The great thing about a DeX Pad or DeX Station is that you can connect wired accessories directly to it, such as a wired keyboard. You can use Bluetooth accessories if desired.
To set it up, connect the DeX Pad or Station to the Fast Charging Travel adapter that came with the phone. Connect one end of an HDMI cable to the DeX's HDMI port, and then connect the other end into the monitor's HDMI port.
If your phone has a case on it, make sure you take it off before connecting because it may cause connection issues. Next, connect your phone to the DeX Pad or Station.
Use your device as a touchpad
If needed, unlock your phone. If it's your first time using DeX, a popup message will display on your phone's Home screen. Tap Continue and then tap Start to allow access to Full Desktop mode. Another Samsung DeX popup will appear - tap OK.
Then, swipe down from the top of the screen to open the Notification panel. Tap the notification that says "Use your phone as a touchpad.” Now you can control the monitor's cursor using your phone! Read the instructions on the monitor, and then select OK.
Switch from screen mirroring
On some phones, your monitor will automatically start screen mirroring whatever is on your phone. To switch to Samsung DeX, open the Notification Panel by swiping down from the top of the screen. Tap the Samsung DeX notification, and then tap Samsung DeX. The monitor will switch to Samsung DeX mode.
Samsung DeX settings
Note: DeX settings can only be accessed in DeX mode.
When you connect your phone or tablet to a DeX product, Samsung DeX Settings will be added to your monitor's Settings list. To access it, select Settings on the connected monitor, and then select Samsung DeX.
From here, you can customize your wallpaper or screen resolution for Samsung DeX, access keyboard and mouse settings, try new features in advance with Samsung DeX Labs, or learn how to use Samsung DeX.
