+# Change Resolution Docker-OSX - change resolution OpenCore OSX-KVM 
+
+The display resolution is controlled by this line:
+
+https://github.com/sickcodes/Docker-OSX/blob/master/custom/config-nopicker-custom.plist#L819
+
+Instead of mounting that disk, Docker-OSX will generate a new `OpenCore.qcow2` by using this one cool trick:
+
+```bash
+-e GENERATE_UNIQUE=true \
+-e WIDTH=800 \
+-e HEIGHT=600 \
+```
+
+To use `WIDTH`/`HEIGHT`, you must use with either `-e GENERATE_UNIQUE=true` or `-e GENERATE_SPECIFIC=true`.
+
+It will take around 30 seconds longer to boot because it needs to make a new boot partition using `libguestfs`.
+
+```bash
+-e GENERATE_SPECIFIC=true \
+-e WIDTH=1920 \
+-e HEIGHT=1080 \
+-e SERIAL="" \
+-e BOARD_SERIAL="" \
+-e UUID="" \
+-e MAC_ADDRESS="" \
