Hi there! I see you're getting sound but no image when using EShare with your Switch device. Let’s figure this out together.

To make sure I’m on the right track, when you say "Switch device," are you referring to the Nintendo Switch console? Also, are you using EShare to mirror the Switch display to another screen, like a TV or a projector?

Meanwhile, here’s a general step-by-step approach we can try:

1. Check Input Source: Confirm that the display device (TV, projector, etc.) is set to the correct input channel where your Switch is connected.

2. Check HDMI Connection: Make sure the HDMI cable connecting your Switch to the display is securely plugged in on both ends. Try swapping the cable if you have a spare, as sometimes cables can cause display issues.

3. Restart Devices: Restart both your Switch and the display device, also relaunch the EShare app afterward. This can resolve minor glitches.

4. Dock Firmware (if using Nintendo Switch Dock): If you are using the official Switch dock, ensure its firmware is updated. Older dock firmware may cause video transmission issues.

5. Display Settings on Switch: In case the Switch’s display resolution or output settings are incompatible with the display, try changing the resolution or enabling/disabling TV mode.

6. EShare Version: Make sure your EShare app is updated to the latest version on your Windows PC.

If you already checked or tried any of these, please let me know so I can dig deeper. Also, if your setup is different, feel free to describe it in detail, and I’ll tailor the solution accordingly.

Are you comfortable trying these steps? Once I know what you tried, I can guide you to the best next step!
