I’m working on an OTT application using React for LG webOS and have a question about supported screen resolutions:
I’ve configured appinfo.json with a resolution of 1920×1080.
When I install this build on FHD (1920×1080), UHD (3840×2160), and HD (1280×720) TVs, the app always renders at 1920×1080 and scales accordingly—UI elements remain consistent across devices.
If I change the appinfo.json resolution to 1280×720, the app renders at that size instead.
My question is: For final submission to the Seller Lounge, do I need to provide two separate builds—one targeting 1920×1080 and another for 1280×720—or is a single 1920×1080 build sufficient to cover all supported TV resolutions?
Hey Elam, I’ve run into a similar situation before. From what I’ve seen, submitting a single 1920×1080 build is usually fine since webOS TVs handle scaling internally. As long as your UI elements scale cleanly and stay readable across different resolutions (HD, FHD, UHD), you should be good. But worth double-checking in the TV Forum just to be safe.
Thank you karum. In the TV forum they mentioned like we need to submit two ipk files and am in some other doubts also
Do I need separate Figma (or other design) files for both 1920×1080 (Full HD) and 1280×720 (HD), or can I maintain a single design source and rely on responsive styling?
If I stick to one codebase, what’s the best way to implement dynamic styling so that UI components—fonts, icons, spacing, etc.—scale correctly at both 1080p and 720p?
I understand that LG Seller Lounge requires separate .ipk packages for each resolution. When I submit the 1280×720 build, I notice the visual quality isn’t as sharp as the 1920×1080 version. Is this drop in quality due to the TV’s internal scaling behavior, or is there something in my styling/assets that I need to adjust?
