Samsung Downgrades External DeX Support on New Galaxy Tab S9 FE Tablets
-
New Galaxy Tab S9 FE tablets have a strange downgrade compared to past models - they don't support external monitor DeX mode.
-
The tablets have USB-C 2.0 instead of 3.2, so lack DisplayPort capabilities needed for external DeX.
-
However, the old Tab S7 FE had USB-C 3.2 and did support external DeX, so the downgrade is inconsistent.
-
You can only use DeX on the Tab S9 FE tablets themselves, not on a connected TV or monitor.
-
It's unclear why Samsung removed external DeX support on the new Fan Edition tablets.
