Hi,
I am trying to create images for projection on custom resolutuon screens, such as super wide 10:1 and tall 1:4 aspect ratio.
I tried everything i can think about, and nothing works.
I always get an image that doesn’t fit my desired aspect ratio.
When i prompt the engine to change it, i get the image stretched or cropped or centered with black masks.
Anyone knows how to create auch images?

Welcome to the forum!
Good question.
I tried a few variations, including trying to get the model to understand that it can create a few separate download images that can be stitched together. Nothing worked as needed.
Perhaps others will be more successful.

I needed a larger image of 1400x1400 pixels, so I looked at the aspect ratio and also looked at what I understand to be DALL-E’s limitation of 1024x1024. I then asked it to create a 1024x1024 image. If I had needed your 1:4 aspect ratio then I would have asked it for 256x1024. For your 10:1 I would have asked it for 1024x10 pixels, using 1024 as the largest side in all cases. I then opened it in Adobe Photoshop, and from the menu I selected Edit > Image Size and first changed the dpi from 72 to 300 since I wanted to print it. And then changed it to 1400x1400. Adobe Photoshop did a good job of interpolating and the end result looked good. There are also other online programs that may be even better at resizing images.

- 1024x1024: A square format suitable for balanced compositions or social media.
- 1792x1024: A wide (landscape) format ideal for panoramic or scenic images.
- 1024x1792: A tall (portrait) format, great for showcasing vertical subjects or details.
1024x1024
1400x1400
Start with the same dimensions as you intend to use. Always better to resize images by a non decimal multiple ie 2:1 not 2.35:1 if possible for best results (but I understand not possible in this case)
Works in this GPT but may need some modifications to prompt in base Chat GPT
If you want a ‘weird’ ratio, first ask it to add a white space border to make the image the right proportions, then resize.
For OP, the 1:4 but with whitespace added to not stretch. unfortunately there are only 3 starting sizes above so the best result I think without any stretching
