Asus PQ321Q - Wrong display resolution monitored


Recommended Posts

AIDA64 reports the current desktop resolution setting, which may or may not match the native resolution of the display.  You can adjust the desktop resolution by right-clicking on the Windows desktop --> Screen Resolution.

We've implemented a workaround for the mentioned issue.  Make sure to upgrade to the latest beta version of AIDA64 Extreme Edition available at:




After upgrading to this new version, make sure to restart Windows to finalize the upgrade.

In Windows 8.1 DPI scaling has been revamped one more time (after revamping it in Vista, and then again in Win8).  It seems the new interface doesn't provide meaningful values, or at least we haven't yet figured out which API call to use to detect the native resolution of the display.  We'll do our best, but we eventually may be forced to simply drop the idea of detecting native resolution, and simply use the logical resolution setting Windows provides via standard API calls.  You can always check the native resolution of your monitors on the Display / Monitor page ;)

Since the upgrade to Windows 8.1, the problem is back. AIDA64 now shows the wrong resolution again (dpi scaling 175%, resolution in AIDA64: 2194 x 1234).

We've just rolled out the first AIDA64 beta with proper handling of DPI scaling, as well as fix for the screen resolution detection issue:


A few icons are left to be updated, and we also have to fix a few issues in the Monitor Diagnostics module. Let me know how it works on your system ;)
