Flickering issues on 2 brand new S27B350 monitors

by jcam222 / March 30, 2013 12:40 AM PDT

I have an Alienware laptop with an Nvidia 260M video card. When home I have used a 24 inch Samsung monitor as my display with no issues for at least 2 years. Recently I decided to purchase a larger monitor so I bought the Samsung S27B350H at Sams Club.

The first night I used it the unit was spectacular. However the second day it started flickering badly, soon thereafter the screen would randomly go black (power indicator on the front of the monitor still on). I found through trial and error that if I unplugged power from the monitor for just a couple of seconds it would fix the issue for sometimes an hour or more. Ultimately however it would start doing the same thing again. I did install the specific driver just in case that would help but it did not. I am set on 60 refresh and graphics are set to 1440 x 900. This is as high a resolution as my card supports. While 1080p is optimal for the monitor it should not cause this issue.

Considering it was new I returned the unit and exchanged it for another of the same. Brought it home and voila......same issue. Again if I unplug it for even just a few seconds when the issue occurs it fixes it.

It seems bizarre to me that two different units could have hardware issues that are identical. It does though lead me to believe its hardware based on the power off / on fixing the issue. Any help is appreciated.

Is this over HDMI?
by R. Proffitt Forum moderator / March 30, 2013 3:22 AM PDT

That sounds like the classic hdmi handshake issue. Frankly and because the HDMI chips can't be reflashed to a version that fixes that you should return them without delay and try another model.

I rarely write this but if this is HDMI, move fast. Save what hair you have.

flicker part 2

Thanks for the reply. I am still messing with this some lol. It appears to me as though generally the issues occurs after the monitor is allowed to go into sleep mode. When it comes back up its ALWAYS flickering. A quick unplug and replug of the power to the monitor and the issue is gone. I hate to give up as when its working the monitor is very nice.

Given what I know about HDMI handshakes and how the code is not upgradeable I'd make the support call and if they fail, return them before you are stuck with them.

Changing the Power Settings

In case someone does not know how to change the power settings to stop the computer/laptop from powering down the monitor. Follow the following steps:

1. Go to Control Panel->Appearance and Personalisation->Screen Saver
2. In Windows 7 you will see a link down the bottom of the dialogue box that says "Change Power Settings"
3. Click on that link and change the power settings profile to never turn off the monitor
4. Return to the screen saver dialogue box and just set the time out to when you want the screen to go blank.

That's it.
