We have a client with a new fujitsu laptop that plugs in to two external monitors. They are complaining of an issue where either of the screens will very intermittently go blank for a few seconds and then come on, whilst the other monitors remain on. There is no "no signal" message from the monitor, the monitor still retains power, the screen just goes blank.
In the last few days my boss' laptop (also fujitsu, also windows 10) has started doing the same thing.
We have tried / Other notes:
-Swapping cables and power for monitors.
-Stress tested the graphics card, RAM, hard drive and ran hardware checks on motherboard. All passed.
-The issue is so intermittent (some days fine, others happens frequently) that we had the computer for 3 days in the office and didn't see it once (or missed it, hard to stare at a screen for 3 days waiting for something to happen).
-Removed drivers and updated (via windows update and SDI).
-One of the monitors is on HDMI and one is on DVI for the client. Both play up.
- Removed one monitor to see if plays up still, it does. Swapped over to the other monitor and that one also has issues on its own.
- My boss has yet to see his main laptop screen go off, or the second external monitor that goes through a port replicator, so each problem monitor seems to be when connected directly into the laptop.
- The laptops are different models with different graphics cards.
- Checked event logs, nothing.
- Checked for updates installed around the time of the issue, nothing. No new programs installed.
- Tried setting monitors in device manager to a default generic driver with correct resolution, no difference.
- Graphics cards not running hot.
Initially I suspected hardware but I've got nothing that really backs that up, we're leaning towards something specific with Windows 10 at the moment but my google fu is running out. Both laptops are under warranty I believe but they are going to be hard pressed to replicate the issue (we couldn't over 3 days) so that's going to be a major PITA if we go down that road and I'm not sure it's the right route.
Any suggestions?
