CPU max out only when plugged to HDMI

Hi,

My laptop started to slow down when it’s connected to a TV screen using HDMI. (It was working fine till a week ago).

The CPU goes to 100% for any SW I open (any browser or other app). When HDMI is unplugged everyrhing works fine.

I tried to check drivers of both Intel HD graphic and Nvidia GT 720M display adapters

Any suggestions?

Thanks in advance

Hi,

Thanks for your help!

Re-installing the drivers did the trick

That's good. Slightly corrupted video drivers are often a cause of "strange" problems.

Try this:

Does it make any difference if you boot up with the TV connected rather than plugging in HDMI after boot-up?

If that doesn’t fix it try uninstalling both graphics drivers and reinstall with latest drivers.

Let me know how it goes.
