The user starts seeing a shape on his display after logging-into his system that overlays on all the windows/applications. Many users encounter the box on the top right of the screen but for a small contingent, the box appeared on other areas of the screen as well. For some of the users, the mouse overlays the box and could be clicked but for others, they cannot click the box. Before moving on with the solutions to get rid of the overlay box, connect your monitor to another system to check if the monitor is not faulty. If that is not possible, then check if the grey box even appears in the system’s BIOS, if so, then get your monitor checked for a hardware issue. Make sure that the magnifier (or any of its zoom settings) is not causing the issue. If you are using a TV as the display unit, then check muting/unmuting the TV resolves the issue. Moreover, make sure Windows and drivers (especially, display driver) of your PC are updated to the latest release.
Solution 1: Change Monitor Settings
You may see the grey box on the display if your monitor settings are misconfigured. In this scenario, changing the monitor settings may solve the problem. If the issue is still there, then try to connect a 2nd monitor to your system and check if that resolves the issue on the problematic monitor. If you are encountering the issue on a laptop, then check if opening the laptop lid (if connected to another display) solves the problem.
Solution 2: Disable the Windows Tips
The grey box could be a result of a stuck Windows tips or tricks ‘leftovers’. In this context, disabling the Windows Tips in the Windows Settings may solve the problem.
Solution 3: Change the Graphics Settings
The box issue could be triggered by different graphics settings. For example, the Shadow play or Overlay features may cause your system to show a box on the display. In this context, editing the undermentioned settings may solve the problem.
Disable Nvidia In-Game Overlay
Disable Relive Recording Indicator
Disable Radeon Overlay
If so then you may have to disable the hotkey combination, to do so, press the Alt + R keys and select the Toggle Radeon Overlay Hotkey box. Then hit the delete key to remove the hotkey (or add a new key combination that you do not use) and the setting will be changed to None. If you are using Radeon Metrics, then hit CTRL + SHIFT + O keys to disable it to check if it resolves the issue (if the Metrics start to show-up, then hit the said mentioned keys again to disable it). You can check if any of the other hotkeys in the Global, Gaming, and Performance Monitoring tabs are causing the issue. If the issue persists, then check if disabling power management in the graphics control panel (e.g., Intel HD Graphics) resolves the box issue.
Solution 4: Clean Boot Your System
Your display may show the grey box due to a poorly written code of an application. In this case, closing/disabling/uninstalling the problematic application may solve the problem. Following are the applications reported by users to create the issue. You may have to close the problematic application (through the Task Manager) or disable it at the system’s start-up, otherwise, you may have to uninstall the application.
Solution 5: Disable Touch Screen of Your System
Your system may show the grey box on the display if the touch screen is hindering the display modules. In this case, disabling the touch screen may solve the problem. If the issue persists, then check if you can swipe away the box with two fingers (after enabling the touch screen).
Solution 6: Reinstall the Graphics Driver
You may see the grey box on your display if the graphics driver of your system is corrupt. In this scenario, reinstalling the (default/latest) graphics driver may solve the problem.
Workarounds
If any of the solutions did not solve your issue, then the undermentioned workarounds (reported by users to solve the issue temporarily) may get the job done. You may try these workarounds one by one to check if any of them removes the grey box on your screen:
Use the Task Manager of Your System
If the issue is still there, then check if any of the system’s tasks in the Task Scheduler is causing the issue. Users reported that the SamoyedAgent.exe task (by Samsung’s EasySupportCenter app) caused the issue. If the issue persists, then check if using a 3rd party utility like Actual Tools solves the issue. If the problem continues, then you may have to reset the PC to the factory defaults. If that did not do the trick, then you may have to get your display unit checked for a hardware issue.
