Resolution question

[pixeluche]

Hello, I`m developing an app (for PC and Ipad) where I use a mutiple UItexture. My textures are 1024x1024 with 72ppi.

All texture have been looking fine on PC, BUT the last friday my customer connected  his laptop to a TV  and the texture image looks a little blurry, my unity project was setup in 1024x768.

so, how can I improve the look? All the image-texture I use are renders,

a solution could be textures of 2048x2048 72 ppi ? it`s my first idea, but I don`t know if it will fix that issue.

1024x1024 is quite big, and will obviously not even fit into 1024x768. Without knowing how you use them there isn't much I can suggest. TVs are generally 1920x1080, which is quite a bit bigger than 1024x768. Will higher res textures improve the look? Certainly.
