+## 2026-09-29 — VideoOut scales a smaller framebuffer set to the output (RADV)
+
+Mesa's VideoOut backend (PS5_Mesa 5115a1d) registers one set of five
+framebuffers per swapchain size, as set *i* at buffer indices 5*i* onwards,
+each with sceVideoOutSetBufferAttribute2 at the swapchain's width and height
+(tiling 0, B8G8R8A8 SDR) and sized in whole 128x128-pixel 64 KiB tiles
+(1920x1080: 15x9 tiles). On FW 12.02 with the 3840x2160 59.94 Hz mode:
+
+- A 1920x1080 set fills the whole output. DXVK 2.6.2's D3D11 and D3D9
+  four-quadrant controls, through Wine (Prospero Win), showed full-screen
+  quadrants on the TV and in a Remote Play capture; with only the 4K set
+  (before) the same 1080p image sat in the top-left quarter.
+- A second set in one process registers: one D3D11 swapchain presented three
+  1920x1080 frames, was resized to 3840x2160 (set 1, indices 5 to 9) and
+  presented three more; all correct on the TV.
+- Other sizes, and more than two sets in one process, were not measured.

+Prospero Win (Wine WoW64 with DXVK 2.6.2) runs its games at a 1920x1080
