Erratic mouse behaviour when connecting laptop to a wireless display (Samsung Smart TV)

[slls1961]

Good afternoon.I wonder if you can help me. I have a Samsung UE50NU7400 smart TV. I have connected my laptop (Asus X205TA, Windows 10 32-bit) wirelessly so I could use the TV as the computer display. This worked well but the mouse movement on the TV is very erratic to the extent that it becomes unviable. I’m using a cordless mouse connected via a USB receiver. I’d be very surprised if this is not a configuration issue on the TV &/or computer. Perhaps the Miracast software on the TV needs updating? I’m hesitant to suspect the computer configuration because it works perfectly when connected to an LG smart TV (32” display). My PC and TV system software are both up to date. Any advice will be greatly appreciated. I’m very keen to get it stable and usable. Many thanks in advance. Best Regards, slls1961

Hi Stuart,
Thanks for reaching out with the details. Since your wireless connection is working well on an LG TV but not on your Samsung, it points toward differences in how each TV handles the Miracast stream rather than a clear-cut computer configuration issue. Here are a few ideas to help narrow down and potentially improve the situation:
• Enable “Game Mode” or a similar low-latency setting on your Samsung TV. TVs sometimes apply extensive image processing which can add input lag and erratic pointer behavior. Game Mode typically bypasses some of these processes and might stabilize the mouse movement.
• Double-check your TV’s Miracast (or wireless display) settings. Although both the PC and TV firmware are up to date, some Samsung models offer additional settings for wireless displays that can be fine-tuned.
• Examine the potential for wireless interference. While your cordless mouse works fine with your LG TV, using the same wireless radio for both Miracast and the USB mouse receiver on your laptop might occasionally result in cross-talk or latency. Testing with a wired mouse, if possible, could help isolate whether the issue is specific to the wireless mouse connection.
• Consider any differences in resolution or refresh rate between the two TVs. Sometimes, the processing required when the TV scales or adjusts for the display resolution can introduce erratic cursor motion.
Since you mentioned both devices are up to date, it may indeed boil down to the Samsung TV’s processing characteristics for wireless display. Try the above steps and see if any adjustments yield a smoother experience.
Let me know how it goes or if you need further help!
