LCD TV 40" screen connected to the laptop with HDMI cable.  Once in a while randomly  goes dark/turns off for 2-3 seconds.  TV power stays on.  Laptop screen stays on.

Should I try another HDMI cable or there issue with a laptop?    Any ideas?  

Thanks.

Maybe a dumb question, but is it possible the laptop is going to sleep or some other low power mode? Go into the power settings and make sure the display is set to never sleep when on external power. (You probably don't want that setting for when on battery power).

All laptop power option is on max performance.  Never sleep/dim and never turns display off.  Besides the laptop screen is always ON.   Only TV screen blinks for 2-3 sec.

A few other possibilities I can think of.........

It sounds like you're using a Windows machine, so go into Device Manager and open the properties for the display adapter, screen (internal and external), network adapter and mouse. In the properties screens, if any of them have an option for "allow the computer to turn the device off to save power", make sure it's unchecked. This option is often separate from the general power settings.

Another possibility is that the external screen is going into low power mode, then waking up. All brands have different ways of setting options, so check its settings (instruction manual often calls it the On Screen Display or OSD) to see if that might be the case.

If none of this helps, then yeah, you might have a cable with a loose wire or maybe the HDMI adapter in either the laptop or screen is a little loose.

Are You Ready for GDPR?

With the GDPR deadline set for May 25, 2018, many organizations are ill-prepared due to uncertainty about the criteria for compliance. According to a recent WatchGuard survey, a staggering 37% of respondents don't even know if their organization needs to comply with GDPR. Do you?

I'll try those settings.  Less likely though.  Its only blink for a few seconds and very randomly.  Doesn't hurt to check anyways.  Thanks.

No adapters.  Just a straight HDMI to HDMI cable.  But could be a loose port in eiher TV or a laptop.

If you have another computer available, attach it to the screen and see what happens. That way, you'll know if the issue is with the original computer or the screen. (Or if you have another screen available, try swapping it in.)

Good luck.

Sorry for the late reply.  Replaced the laptop and the HDMI cable.  Will monitor few days to see if the TV still blinks.  Thanks.

Replaced laptop and HDMI cable.  Still blinking randomly.   Tried another HDMI port on TV as well.  

At this point I suspect a house power flux that makes a TV blink. Light bulbs do blink as well.
