Ok, my first attempt. Night Cafe.  Just something basic.

Midjourney v4

Some are for Cell Phone Walls above ,

Others can be resized if --q is high with no issue 

With the new 16:9 HD and 4K resize fine.

While some other sizes besides resizing need sizing adjustments also,

unlock the proportions and pull as needed .

to pull back to original shapes , I have done that on the walls uploaded to WC.

That is using MidJourney , now starryai renders in 4K 8K 16K

*** So Yes , That means the walls need some Post Work before uploading but that's fun too. ***

Hopefully Midj will render in 4 K soon.

** Note **

I think with AI coming onboard we should have a Cell Phone Wall category now .

cell sizes fit to screens like our walls do .

One other note.

16:9 needs to be rendered the 4 times to 

get to Max. Res./Quality Detail

All do.

So 1st save. An image, then click on detailed redo, then click on Beta redo, then that gets you to the final Hi res.

Might be worth the cost , I think ...
