Original camera looks washed out

In most cars with a factory camera the original camera can be maintained by using a harness.
The new screen with display the image coming from the camera BUT many cameras are made to display on a 480x234 analogue screen.  Most screens are now 1024 and so the image may look washed out.  The only way of getting a better image is to either use an much older (even a 800x480) screen or replace the camera
