Something along the lines of 2K or more with at least good colour accuracy would suffice for me! It’s all I need for the photo editing part. Having plugged it into my 4K TV it went very well. All the UI elements and such displayed perfectly and smoothly for the most part. So 4K on the Steam Deck is most definitely doable! At least if you disregard gaming that is which isn’t the main goal for this project.

Does your steam deck output to 8K when you plug it into the TV? How are UI elements and FPS on that resolution for you? Would be fun to see where the limit would be.
