#### This example shows how to change resolution after the container is created.
First step is to stop the docker daemon
```
sudo systemctl stop docker
```
The second step is to change container config in
```
/var/lib/docker/containers/[container-id]/config.v2.json
```
(Suppose your original WIDTH is 1024 and HEIGHT is 768, you can search 1024 and replace it with the new value. Same for 768.)

```
sudo systemctl restart docker
```
