4:3 vs 16:9 Effective Viewable Screen Size: For classic 4:3 retro games (PS1, SNES, N64, Dreamcast), the Anbernic RG Cube's 3.95" (1:1) panel yields a 3.49" effective diagonal (75% active screen area with horizontal letterbox bars on top and bottom (native 1:1)), while the TrimUI Brick's 3.2" (4:3) panel yields a 3.2" effective diagonal (100% full screen without black bars (native 4:3)). This gives the Anbernic RG Cube a 0.29" larger active 4:3 diagonal (19% more active display area). For 16:9 widescreen content (PSP, Switch, streaming), the Anbernic RG Cube delivers a 3.2" effective diagonal (56% screen usage) versus 2.94" (75% screen usage) on the TrimUI Brick, making the Anbernic RG Cube larger by 0.26" (+19% active 16:9 area).
