OEM Logon Screen Background RRS feed

  • Question

  • So I found this article at http://huddledmasses.org/customize-your-windows-7-logon-screen/ and I noticed that the 1680x1050 resolution was not supported. I was wondering if anyone could shine some light onto why this is, and I was wondering if I might be able to have this res supported. Right now my 22" monitors default to a 1024x768 res, which is horrible for trying to do custom backgrounds on these monitors.

  • In this case, I think that aspect ratio (screen width / screen height) is more important for Windows than screen resolution. There are many common screen resolutions, but there are fewer aspect ratios. For example, 1680x1050 gives an aspect ratio of 1.6. 1920x1200 gives the same aspect ratio.

    As far as I'm concerned, Windows will choose a background image whose aspect ratio more closely matches that of your screen resolution, from a list of common aspect ratios (1.25, 1.33, 1.60, 1.67, 1.77, and 1.78). Once the best match is found, Windows tries to find a background image with the same resolution as your screen (this is to avoid scaling, an expensive operation). There are multiple supported screen resolutions per aspect ratio, as the article you mentioned explains:

    For 1.25 : 1280x1024

    For 1.33 : 1024x768, 1280x960, and 1600x1200

    For 1.60 : 1440x900 and 1920x1200

    For 1.67 : 1280x768

    For 1.77 : 1360x768

    In your case, as 1680x1050 is not directly supported, you should choose a 1440x900 or 1920x1200 picture. Try both and see what gives the best results. Note that for performance reasons you're limited to a 250 KB picture file.

    By the way, the behavior is by design and cannot be changed.

  • I'm having this problem:

    http://www.sevenforums.com/hardware-devices/202461-triplehead2go-stretched-custom-default-login-screen-windows-7-pro.html

    As I have a triple monitor setup, I have an aspect ratio of 3.75.  The login screen appears to be limited to a maximum width since my monitor is so wide.  I'm trying to find out what that width is.  I'd be nice if the login screen in this setup would go all the way across the three monitors.  But I'd be fine if it didn't and only didn't stretch (or squish the length of) my custom image.  But I don't know what the width is.

    Any info would be helpful.  Thanks in advance.
