This App is "incompatible" issue

So I've noticed, that sometimes even when an app is compatible with my device, that it shows as "incompatible" on the android market, thus blocking me from installing it.

I found this issue was happening when I had changed my LCD Density from the stock 240, to 200. I changed it back in the build.prop, rebooted, and low and behold it worked again.

Keep this in mind, that some apps that tweak your UI might cause false app market incompatibility issues.
