I can't be certain but it appears as if...

... if an image (such as normal jpeg) is used which is bigger than the desktop resolution such as from a camera, then the Lock/Login background will only show a *very low resolution* pixelated and colour corrupted version of the original background image.

Why is this? Is someone going to fix it? Do you know about this bug (which has been there for years)?

Using latest Windows 7 64-bit

Unfortunately this isn't something that can be fixed. Windows 7 limits the Windows Logon image to 256 KB in size, so DisplayFusion has to heavily compress the image until it's small enough to be loaded by Windows.

Sorry!

Well that explains it then. Thanks.

But do you actually re-scale the image if it is massive down to the desktop resolution first before compressing it, which would save a lot of size. The reason I ask is because I notice very large camera images tend to end up looking much worse. It would be stupid to try and compress a 4Mb 10 megapixel image down to 256KB without first scaling it down to 1080P or 1440P.

That's a stupid limitation in Windows 7. Does Windows 10 does have this limitation also?

I assume we scale it down before compressing it, but I'd have to check with our devs on that.

Windows 10 doesn't have that same limitation, no :)
