So I have this spare Samsung UHD monitor model: U28D590D and I’m trying to use it as an external display for my laptop but every time I connect the laptop to it the monitor screen just goes black and the computer does not even detect the monitor when I go to display settings (yes I tried having windows manually detect). I know the monitor is some what working because when nothing is connected it still displays a notification saying check signal cable and I’m able to access a limited settings menu as well. I know the laptop and HDMI cable are not the issue as well because I’ve tested both on other Samsung monitors as well as a couple Samsung 4K TV’s and they all work without a problem and the computer detects all of them and I have also tried using different laptops to connect to the monitor with the same issue of a black screen and the monitor not being detected. I would have thought it being an issue with the actual HDMI ports on the monitor or the panel was messed up but I can still connect my Xbox One and it displays the Xbox without any problem so it definitely is an issue with the monitor. Please help me out here I want to be able to use this monitor!
Hi @Paul Aquino Couple of things to look at as I think you didn’t say that you tried. When check signal cable is displayed enter Settings > PC/AV mode and check that it is set to either HDMI 1 or 2 depending on input Also have you tried to manually set up the connection in the monitor? Go to Settings > Source Detection > Manual and select the source. Other than that I don’t know if this may be of interest. You have to pay for it but it may have some more useful information in it.
