I am currently working on a project that requires me to put together an image to be presented on a TV screen. My assumption is that the TV screen size and resolution shouldn't matter as long as I have my aspect ratio correct and use a high res image. I have my image set to 9:16 aspect ratio and 2400x2400 resolution, so the image should fit to fill the entire TV screen, correct? I am under the impression that my image should fit to fill the screen unless the TV itself has some weird aspect ratio settings but would really love to be corrected if I am wrong.
The options you have to present an image with a different aspect ratio than your display are:
- Squish (Please, do not use this)
Normally a TV does not do anything by itself.
They need to receive a signal, normally from a HDMI or similar port. So what is shown depends on your computer running PowerPoint for example.
Some TVs have some kind of built-in software and a USB plug so they can display the content of the USB, maybe a series of photos, videos, or both. You need to see the TV user manual.
Probably some other "software" to read things online. Some can display YouTube content or something similar.
They need to receive a broadcast. (But you need to own a TV station... not likely)
The most viable option is number 2.
Take Gimp which is free.
Backup your original file
Your image has 2400px Crop the image X dimension to 1350px. (That number is the 2400px at the base multiplied by .5625 which is the 9/16 proportion.
Now you can prepare two versions, and resample it to 1920px in height, and automatically will give you a 1080px base, and a second version to 3840x2160px.
Send them both with the proper name and let the other person choose.
I have my image set to 9:16 aspect ratio
If the TV is vertical it is okay. But if not it should be 16:9
and 2400x2400 resolution,
on what? I suppose that is the original image's size.
so the image should fit to fill the entire TV screen
That image can not do anything on its own. You need to crop it, resample it, or make a camera movement like vertical panning. Probably the best option is making a video on a video editor doing the necessary actions.
TV itself has some weird aspect ratio settings
What has a weird aspect ratio is your image. The project settings of a typical TV 16:9 project are either 1920x1080 Full HD or a 4K project, double that 3840x2160.
To maximize quality go for the biggest size, prepare your project as 4k.
If you only drop an image, you will be at the mercy of the software handling it. It might crop it, squish it resample it, but with no control of your part.
My assumption is that the TV screen size and resolution shouldn't matter
Yes, it does. Full HD vs. 4k, vertical or horizontal.
