Summary

  • Fixes TV: Increase poster size and decrease hero size on Home screen for better content visibility #163. TvSkylineSectionFeed (shared by Home, For You, and Library Detail) was rendering poster cards at the Dense size (88x132dp), packing ~9 tiny posters per row with rating/progress overlays hard to read from typical TV viewing distance.
  • Switches poster cards to the standard size (130x195dp), landing around 6-7 posters visible per row, matching the balance described for Emby/Wholphin in the issue.
  • Raises the row band height fraction (TvSkylineRowBandHeightFraction, 0.50 -> 0.58) so the taller cards have room without clipping against the next row's peek, which also shrinks the hero/marquee's share of the screen.
  • Removes the now-unused RowDimens.DensePosterWidth/DensePosterHeight constants.

Since this layout is shared across Home, For You, and Library Detail, the change applies consistently to all three "hero + rows" screens rather than only Home.

Test plan

  • Build and run on an Android TV device/emulator (NVIDIA Shield or similar) and confirm poster size/hero balance visually
  • Verify D-pad navigation and focus behavior across rows is unaffected
  • Check Home, For You, and Library Detail screens for consistent poster sizing
  • Confirm no clipping of the row band against the marquee/hero content at common TV resolutions (1080p, 4K override)

Note: I was unable to build or visually verify this change in my environment (no JDK/Android SDK available), so the exact 0.58 band-height fraction is a reasoned estimate based on the existing card/spacing math rather than something eyeballed on a screen. Please sanity-check on a real device before merging, and feel free to nudge the constants if the balance isn't quite right.

Summary by CodeRabbit

  • UI Improvements
    • Updated Android TV content rows to use standard-sized poster cards for improved visibility.
    • Adjusted row spacing so taller posters display without clipping or obscuring the next row.

The shared Home/For You/Library-detail row feed rendered poster cards
at the Dense size (88x132dp), packing ~9 tiny posters per row and
leaving rating badges and progress overlays hard to read from a
typical TV viewing distance. Switch to the standard poster size
(130x195dp), landing around 6-7 visible per row, and give the row
band more height so the taller cards don't clip against the next
row's peek -- trimming the hero's share of the screen in the process.

Fixes Silo-Server#163

Review Change Stack

📝 Walkthrough

Walkthrough

The Android TV Skyline feed now uses standard poster cards. The reserved row-band height increases from 0.50 to 0.58. Obsolete dense poster dimensions are removed from the spacing theme.

androidTvApp/src/androidMain/kotlin/org/siloserver/silo/tv/ui/components/TvSkylineSectionFeed.kt, androidTvApp/src/androidMain/kotlin/org/siloserver/silo/tv/ui/theme/Spacing.kt
The Skyline feed uses RowDimens.PosterWidth instead of the dense poster width. The row-band height fraction increases to 0.58f. The dense poster height and width constants are removed.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 01553

The layout change enlarges shared TV poster cards and reduces the hero area, but the resulting height allocation may clip marquee content at common TV resolutions. The PR is mergeable with explicit owner awareness or follow-up to adjust the row height responsively.

Reduce TvSkylineRowBandHeightFraction or make the layout responsive.

At 1920×1080 (960×540dp), the padding leaves only 162.8dp for TvFocusMarquee. At 1280×720 (640×360dp), it leaves 87.2dp. TvMarqueeBlock can require about 206dp, and TvFocusMarquee clips its content. Use a measured layout budget that preserves the marquee content at both reference sizes.

Could you add a couple of device shots before we merge this? Shield (or similar), D-pad, Home / For You / Library Detail, especially whether the 0.58 band clips the next-row peek or focus-lift at 1080p and 4K. I can't ship a TV layout change on tokens alone.

Verified on device before merging.

Set up two Android TV emulators (API 34, tv_1080p and tv_4k profiles), logged into a real Silo server, and D-pad navigated Home, For You, and a Library Detail screen on this branch.

Home / Library Detail (1080p): hero renders at the top, first row (Continue Watching / Recently Added) is fully visible, ~6-7 posters per row as intended. Second row peeks cleanly at the bottom edge — no clipping. Moving focus into the second row, the focus-lift/scale animation and border render fully, even with the row sitting close to the bottom edge.

4K profile: Android TV's WindowManager caps UI compositing at a 1920x1080 base regardless of the panel's declared resolution (dumpsys window displays shows init=3840x2160 but base=1920x1080; forcing wm size 3840x2160 gets silently reverted by the system). This matches the original issue's own diagnostics (Physical size: 3840x2160, Override size: 1920x1080). Logging into the 4K-profile emulator separately and capturing Home produced a pixel-identical layout to the 1080p device — there's no separate 4K Compose surface for the 0.58 band fraction to break.

For You / Recommendations didn't have data to render through TvSkylineSectionFeed on this account (empty state), so that one's unverified against real content, but it shares the same component as Home and Library Detail, both of which check out.

Screenshots incoming in a follow-up comment.

Superseding this with #257, which makes poster size a user-facing preference on both phone and TV rather than a hardcoded bump.

#163's commenter asked to "increase poster size or give us the option" — #257 wires up the server's \ setting (poster size compact/standard/large plus a caption style axis), so anyone who wants larger TV posters can pick Cinema or Large, and the choice syncs across their devices or stays pinned to one via an "Only this device" toggle. It also derives the Skyline row band height from the scaled card height instead of a fixed fraction, which is the same hero/row balance problem this PR's \ constant was solving — but computed per preset rather than estimated.

Thanks for the work here, and for flagging the band-height clipping; that constraint carried over into the derivation. Closing as superseded.
