[TizenOS] Small/unscaled UI text on Samsung TV - UE85DU7190UXZT (TizenOS 8.x)

[jyan1992]

Bug Description

The UI text in Nuvio TV appears very small and unscaled when running on Samsung TizenOS 8.x via TizenBrew. All text elements (titles, labels, navigation items, metadata) are rendered at a very small size, making the app nearly unusable from a normal TV viewing distance.

Device Information

• Device: Samsung UE85DU7190UXZT (85" Crystal UHD)
• Software version: T-KSU2EDDEUC-1400.0
• TizenOS version: 8.x
• Installation method: TizenBrew module (NuvioMedia/NuvioTVTizen)
• Nuvio version: Beta 0.1.2

Steps to Reproduce

1. Install Nuvio TV via TizenBrew on Samsung TV (TizenOS 8.x)
2. Launch Nuvio TV from TizenBrew modules
3. Observe all UI text elements are very small / not scaled to TV viewport

Expected Behavior

Text should be scaled appropriately for a TV display, following the TV's resolution and viewing distance conventions (similar to native Samsung apps or other Tizen apps).

Actual Behavior

All text is rendered very small — appears as if the web app viewport is not scaling correctly for the TV resolution (3840x2160 on 85" screen). The Tizen wrapper does not seem to apply the correct viewport meta tag or CSS scaling for TV displays.

Possible Cause

The Tizen wrapper (NuvioMedia/NuvioTVTizen) may be missing a proper viewport configuration or CSS transform: scale() / zoom for TizenOS 8.x, which handles viewport scaling differently from previous versions.

Additional Notes

• The app also shows performance/fluidity issues on this device (related to issue UI Performance and Navigation Bug Report #37)
• No similar issue has been reported for TizenOS yet — this is the first report specific to TizenOS 8.x
