I've a weird bug with my C49hg90dm. Sometimes when I turn on the monitor I've a glitched black screen followed by a strange cyan-blue screen stranded by lines.
I noticed that the monitor's menu still work in this state but doesn't appear because I can still turn off the monitor normally by pressing the main button, go down and pressing it again. Then when I turn on the monitor again everything works normally. It also work fine if the source change I think because the glitch desappear if I reboot the computer.
I don't know if this issue appear randomly or after a fixed number of power-up. I've also noticed that the image seems slightly different when the monitor is about to glitch on the next power-up.
I don't know if my description is clear ? It's not really annoying but I just hope that doesn't damage the monitor over time.
My monitor is plugged on a surge protector Eaton ellipse eco 650 and with a displayport.
Solved! Go to Solution.
In my case it only happens for Mini-DisplayPort and DisplayPort connections. I've tried 2 different computers. Then I tried another DisplayPort cable (Pin 20 disabled), not the included one. Nothing changes. My Panel version is FD04.
DisplayPort = Glitch
HDMI = Works so far
If this is the case Sekko, then honestly repairs would be recommended. It's possible there is a defect in the DisplayPort causing this to happen. Mind shooting us a private message with the serial number here: http://bit.ly/2mcMgp1

Mine was purchased on November 2018 (manufacturing date October 2018) and it also came with firmware 1017.0, the issue persisted for months until I upgraded it to 1019.0 two weeks ago. Not sure what you mean with the other firmware fixes, maybe you are referring to a different issue that is being discussed in another thread that is also related to waking up from sleep but that renders the monitor completely unresponsive, I have never experienced that problem so I don't know if this firmware upgrade solves it.
Same issue here in Italy
glitches from displayport , ok from hdmi
the monitor has 35 days now, ion the first weeks the menu still worked and I menaged to turn off and turn on to solve the problem but now it doesn't work and I must plugged off everytime.
Since yesterday there ist a new firmware version (1090.0) available. My experience after 1 hour and 50 tries to switch the display off/on. There is no glitch (at the moment) anymore! 🙂
I hope this is the final solution for the power-up glitch. I am looking forward to your feedback!
after thousands of on/off I can confirm this new firmware solved the problem (finally). no glitch!!
I'm happy for this, thanks Samsung
