    Some things don't show up correctly on my second monitor

    things like my steam opens up across my monitors for some reason, any things like the exit fullscreen youtube popups are in the wrong spotDual monitors weird glitches? [​IMG] Dual monitors weird glitches? f5dc190e-e7cb-4b7d-9c9d-f1056de087bc?upload=true.png

    My monitor configuration: Dual monitors weird glitches? 59158b8a-0e81-41c2-a9d8-12618f5a50e4?upload=true.png

    Monitor 1 is a 2560x1080p 75 Hz, Monitor 2 is a 1920x1080 60 Hz. How can I make the youtube popup be at the top center like it should be, and my steam open in the right spot? It always does these, even if I resize my steam.

  2. Weird graphical text editor glitch in a dual monitor setup on windows 10

    My dearest superusers,

    I have a very weird graphics 'glitch' for certain IDE's or editors, like TexStudio and Spyder. It happens that certain lines or words overlap with each other, and sometimes certain lines have different fontsizes even (not shown in next image)

    Screenshot for one example of overlapping words:

    It happens usually in my secondary monitor (LG Flatron E2350V), but if I remember correctly, it had appeared on my primary as well. My primary is just the one of my laptop (HP Pavilion - 14-al125nd). What I have noticed (from what I remember) is:

    • When the problem appeared in Spyder in primary monitor, it was
      sometimes solved by saving the python file
    • When the problem appeard in Spyder in secondary monitor, it was
      sometimes solved by maximizing the window.
    • And at times none of the above methods worked for no monitor.
    • When I drag one of the text environments (texStudio or Spyder) from monitor 1 to monitor 2, the text transitions into the glitched version.
    • Also,some IDEs like Matlab, never experienced this problem. (And till now, I have never seen the problem elsewhere
    • As far as I know, these two programs are the only ones where the glitch appeared.
    • Lately, the problem does not appear in first monitor, but it still does in second one.

    This suggests that the problem is time-varying and possibly also varies in its characteristcs.

    To solve the problem, I've tried to:

    • update to latests graphics drivers, both my integraded Intel card (HD
      Graphics 620), as well as my dedicated Nvdia GeFore 940MX card.
    • Otherwise I've tried to search online but frankly, I do not really
      know the right search terms to find the same problem. Therefore I
      hope to find some answers or suggestions on this site!

    Just to be clear, my question is what causes and/or what can potentially solve the problem?
    Of course I do not know what information could be used/required to answer this question, so if there are any questions of additional details that I did not mention, please ask.

    Sidenote: I am not sure whether my tags are correct either. Feedback is appreciated.

    Windows 10 Update - Now my dual monitors do not work


    One of the possible reasons why Windows 10 was unable to detect your dual monitor is an outdated or incompatible graphics driver. To best address your concern, we need you to answer the following questions:

    • Which Windows 10 build are you using?
    • Have you already tried performing the troubleshooting steps suggested by
      Mauro Cavallin on June 16, 2017?
    • Are both of the monitors not working just like what the original poster was experiencing? If yes, have you tried disconnecting one of the monitors? What was the outcome?
    • What troubleshooting steps have you done so far?

    We will be waiting for your response.
