When I connect my laptop to a monitor through the HDMI connection, I have a hard time controlling the mouse using the touchpad.

I'll try to explain as best as I can:

The touchpad works perfectly fine until I plug in the HDMI cable, then the cursor moves jumpy, and response badly. It moves in the general direction I try to move it, but not in a straight line.

The behavior seems to be very similar to the one described in this question. However, in my case it's not the power supply that's the problem, it's the HDMI.

Does anyone know what the cause can be and if there is a solution?

My laptop is an Asus Zenbook ux32vd running on Windows 8

  • Can you verify that it is not a general poor speed of graphic rendering issue (cursers do go into hardware render, when drivers are properly installed)? Other than the touchpad, does a HD movie play ok? Do games work up to par for the equiptment? Are all other aspects of the video working fine but the curser?

  • @Psycogeek, I can verify that I don't have any problems with the graphics. I haven't tried gaming, but high def videos work fine.

  • I Might find it time to use one of the "latency checker" softwares , and see if it spotted anything. Sometimes the Extra parts of a touchpad driver are a "process" that can be controlled. If you know of its process you could attempt to put it into High Priority in a task manager. It would be interesting to see the "Gpu load" (ammount of work the gpu is doing), I would only know how to do that for my own puter. Use the resource monitor and check for both CPU use & cpu frequency, there is one type of power profile in windows that can act like cpu throttling.

I have exactly the same problem with the same computer. I have found that the problem is more tolerable if you set the pointer speed to a smaller value, as if the amplitude of the jumps gets smaller. (Control Panel > Mouse Properties > Pointer options > Motion > Select a pointer speed). I haven´t found a real solution. Guillermo
