Dahua DHI-PHGOA6-PH vs Unilumin Usurface III 6.67 (1200×1200)

6.667 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: 7.68 × 4.80 m and 9.60 × 6.00 m respectively.

What the numbers say

Both resolve to about the same density (22,500 and 22,500 pixels per square metre), so pick on weight, power or what your shop already owns rather than on image detail.
Dahua DHI-PHGOA6-PH is the lighter rig: 30 kg/m² against 34 kg/m². Across this wall that is 856 kg of difference, 1,220 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 20.3 kW versus 37.4 kW, and 8 versus 15 circuits at a 16 A/230 V supply with an 80% derate.
Data is lighter on Dahua DHI-PHGOA6-PH: 2 runs against 3, at 25 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: 960 × 960 mm against 1200 × 1200 mm, so 40 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.
