    On a screen with 300dpi the checkbox looks really bad.
    Is there a way to get a better quality image in a checkbox celltype?

    Hello,

    I don't see the problem with Spread.Net13 in a 300 DPI environment. What is the spread version that you are using?
    Can you try to test your application with Spread.Net10 v3/+ with .Net F/w > 4.7 ?
    Also, see if the following helps:
    Add the following line to the app's config file:
    <appSettings>
    <add key="EnableWindowsFormsHighDpiAutoResizing" value="true" />
    </appSettings>

    Thanks,

    sorry forgot to mention that we are still using 11.45.20183.0.
    Is the appsettings key also supported in V11.45?

    Hi,

    As you are using Spreadv11, you should not face the issue. If you create a simple application (drag drop FpSpread onto form, bind it to include a CheckBox field) then executing it over a high DPI environment, do you still face the issue? If not, could you share a stripped down version of your application.

    Thanks,

    Here is a little sample app and a screenshot on how it looks on 300dpi.

    Hello Thomas,

    Unfortunately, I still could not replicate the issue. See attached image.
    I executed your application over Win7 having 300+ DPI and using Spread 11.45.20183.0.
    Were you/anyone else able to observe this issue over any other environment? To continue further, we need to first replicate the issue in order to assist you effectively.

    Thanks,

    Did you run the sample on Win10?

    Thomas,
    Yes, I checked the issue over Windows10 and the checkbox looks proper.

    Thanks,
