The graphics adapter does not have any onboard dedicated graphics memory.
The Windows Experience Index (WEI) tool has been run to calculate a score that rates your computer's performance.
You select “View and print detailed performance and system information” to view the current WEI results.
In this scenario, when you select “View and print detailed performance and system information”, the "Gaming graphics" Details column will show "Not Detected". The expected behavior is that the Details column should show the total available graphics memory.
Since there is no dedicated graphics memory detected, WEI will report "Not detected" instead of the total available graphics memory.
This wording can be safely ignored as it does not affect the performance of Windows.
