Frame TV Art Resolution Guide
Resolution controls detail; aspect ratio controls shape. Both need to match the screen for a clean result.
Resolution: 3840 × 2160
A 4K UHD television has 3840 horizontal pixels and 2160 vertical pixels. Supplying those dimensions avoids unnecessary enlargement.
Aspect ratio: 16:9
The ratio describes the shape of the image. A 16:9 composition fills most modern televisions; other ratios require cropping, borders or a digital matte.
Use JPG for broad compatibility
A high-quality JPG balances visual detail with manageable file size. Keep a master copy and transfer the final display file rather than a messaging-app preview.
