 ### tidb_low_resolution_tso
 
-- Scope: SESSION
+- Scope: SESSION | GLOBAL
 - Applies to hint [SET_VAR](/optimizer-hints.md#set_varvar_namevar_value): No
 - Type: Boolean
 - Default value: `OFF`
 - This variable is used to set whether to enable the low-precision TSO feature. After this feature is enabled, TiDB uses the cached timestamp to read data. The cached timestamp is updated every 2 seconds by default. Starting from v8.0.0, you can configure the update interval by [`tidb_low_resolution_tso_update_interval`](#tidb_low_resolution_tso_update_interval-new-in-v800).
 - The main applicable scenario is to reduce the overhead of acquiring TSO for small read-only transactions when reading old data is acceptable.
+- Starting from v8.3.0, this variable supports the GLOBAL scope.
