# Green or Black screen
Video cards
When running on video cards which don't support half precision floating point numbers (a known issue with 16xx cards), a green or black screen may appear instead of the generated pictures.
This may be fixed by using the command line arguments `--precision full --no-half` at a significant increase in VRAM usage, which may require `--medvram`.
Certain GPU video cards don't support half precision: a green or black screen may appear instead of the generated pictures. Use `--upcast-sampling`. This should stack with `--xformers` if you are using.
If still not fixed, use command line arguments `--precision full --no-half` at a significant increase in VRAM usage, which may require `--medvram`.
# "CUDA error: no kernel image is available for execution on the device" after enabling xformers
Your installed xformers is incompatible with your GPU. If you use Python 3.10, have a Pascal or higher card and run on Windows, add `--reinstall-xformers --xformers` to your `COMMANDLINE_ARGS` to upgrade to a working version. Remove `--reinstall-xformers` after upgrading.
