Distance Field Shadows quality??

Guys I can’t find a way to adjust the quality of my Distance Field Shadows.
I’ve tested it with directional light and with a point light. Turned off static shadows.
The only options i see in the light settings are:

Distance Field Shadows
Raytraced DistanceField checkbox
DistanceField Trace Depth
Ray Start Offset Depth

Where do I adjust quality of resolution of the shadows. Now it looks very low quality…
Couldn’t find it in the docs…

Best,
Maarten
