Desay M6 vs Unilumin Usurface III 6.67 (1200×1200)

6.25 mm against 6.67 mm · specifications from both manufacturers' datasheets

Side-by-side specifications, then the same wall built from each tile, so the comparison is in panels, kilograms, circuits and data runs rather than in marketing copy.

Whole cabinets rarely hit an identical size, so each wall is the closest build to a real video format (16:9 or 16:10) near 8 m wide for that tile: 8.00 × 4.50 m and 9.60 × 6.00 m respectively.

What the numbers say

Desay M6 resolves finer: 25,600 pixels per square metre against 22,500 for Unilumin Usurface III 6.67 (1200×1200), 14% more. On a 8 m wide wall that is 1,280 px across versus 1,440 px.
Desay M6 is the lighter rig: 24 kg/m² against 34 kg/m². Across this wall that is 1,091 kg of difference, 985 kg versus 2,076 kg, which moves point loads and can change the hoist call.
Unilumin Usurface III 6.67 (1200×1200) draws more: 650 W/m² against 550 W/m² at full white. For this wall that is 19.8 kW versus 37.4 kW, and 10 versus 15 circuits at a 16 A/230 V supply with an 80% derate.
Data is lighter on Desay M6: 2 runs against 3, at 28 and 16 panels per port respectively (60 Hz, 8-bit, ports loaded to 80%). Fewer runs means fewer home runs to pull and fewer processor ports to find.
Different cabinet formats: 800 × 900 mm against 1200 × 1200 mm, so 50 tiles versus 40 for the same wall. Fewer, larger cabinets build faster; smaller ones give finer control over wall dimensions and are easier to handle alone.
Estimated truck space: 2.9 m for Desay M6 against 5.4 m for the other, including spares, cases and cabling.
