Anyone else have this issue? I have a TrendNet USB switch connected to my laptop and I use display extend to have 2 monitors. Sometimes I see the screen brightness flicker. I reduced my frame rate to 50 but it still occurs.

Maybe can anyone recommend a better USB switch or other settings I could try?


  • Is your laptop connected through battery alone, or to the powersocket? – LPChip Apr 10 '14 at 11:55
  • It's connected to power. – sproketboy Apr 10 '14 at 12:30
  • It could still be a power management thing. Can you try setting your power management to high performance, and see if that solves it? – LPChip Apr 10 '14 at 13:48
  • I rechecked all my cables and made sure they were secure and the problem seems to be gone now. :) – sproketboy Apr 10 '14 at 15:26
