Sharpness and pixel density
The 48″ 4K OLED is sharper at 92 PPI versus 80 PPI on the 55″ 4K TV, a 15% increase in pixel density. Individual pixels stop being visible to 20/20 vision beyond about 37″ (95 cm) on the 48″ 4K OLED and 43″ (109 cm) on the 55″ 4K TV.
Workspace
Both show nearly the same number of pixels (8.3 vs 8.3 MP), so at 100% scaling they fit the same amount of content.
On a Mac
The 48″ 4K OLED: visible pixels. At 92 PPI, text looks noticeably pixelated at normal desk distance, especially next to a MacBook’s Retina screen. The 55″ 4K TV: visible pixels. At 80 PPI, text looks noticeably pixelated at normal desk distance, especially next to a MacBook’s Retina screen.
Why this matters: macOS draws its interface at exactly 1× or 2×, so displays near 110 or 220 PPI look best. Read the Mac monitor guide or how we rate sharpness.
Desk and viewing distance
For comfortable viewing, sit roughly 61″ (154 cm) from the 48″ 4K OLED and 69″ (176 cm) from the 55″ 4K TV. A desk at least 150 cm deep keeps the larger screen from feeling too close.
