Hmm, that’s strange. My resolution is 1920 x 1080, DPI settings are all standard.
Your picture looks like Windows chose the 16 x 16 version (instead of the 32 x 32 version) of the icon, but it normally shouldn’t do this as SyncTrazor now has all needed icon sizes 
. Maybe it is somehow related to some of the “unneeded” icon sizes (like 24 x 24) I incorporated into the .ico file which are then used on smaller resolutions (but this is just a guess). Most guidelines say that Windows Vista and higher need the icon sizes 16 x 16, 32 x 32, 48 x 48 and 256 x 256, but the official guidline for example also recommends 40 x 40 (and some more) for some cases with a higher DPI setting 
.
