ComfyUI txt2img Upscaler Workflow
I wanted to share the workflow I am currently using. Also would like to know if anyone can give me tips and tricks about improving my workflow.. as expecting the 4x Upscaler get bit popular, I liked to showcase which nodes it needs. would like to know if you have any suggestion over the parameter settings, let's meet in comment section!

How to use: download zip file and extract all.

ComfyUI/
└── user/
├── default
├── workflows
└── 4xZIT.json

now you can restart comfyui and find it in your workflows.
SUGGESTION: using dpmpp_2m_sde and mode type Linear will adjust/fix your images
default: mode_type: "none" don't changes your image as final output.
