Main trade-off
JMGO O2S Ultra
The fixed UST lens still requires exact cabinet height and physical alignment.
Head-to-head
Choose O2S Ultra for a shorter lens-to-screen distance on a media unit. PX4 Pro suits plans above 150 inches within its stated image range.
Before you choose
JMGO O2S Ultra needs 1.4 ft from lens to screen for a 120-inch 16:9 picture. Hisense PX4 Pro needs 1.7 ft.
What this is based on
Width = diagonal × 16 / √337. At 120 inches the width is 104.6 inches. Multiply by each documented throw endpoint and divide by 12 for feet. This excludes digital zoom, keystone, cabinet offset and lens-shift limits.
Main trade-off
The fixed UST lens still requires exact cabinet height and physical alignment.
Main trade-off
Its 0.2:1 fixed lens still needs careful cabinet and screen geometry.


Choose O2S Ultra for a shorter lens-to-screen distance on a media unit. PX4 Pro suits plans above 150 inches within its stated image range.
UST geometry must be measured from the lens
Winner by situation
JMGO uses 0.16 throw and Hisense 0.2. The difference is about 4.2 inches at a 120-inch picture, but the cabinet-to-wall gap also depends on the lens position in each chassis.
JMGO lists up to 150 inches and PX4 Pro up to 200. Confirm screen and mounting dimensions before choosing a larger future picture.
Use 1.4 ft for JMGO O2S Ultra or 1.7 ft for Hisense PX4 Pro, measured from the lens. Check the cabinet and mounting clearances separately.
The documented platform is Google TV on JMGO O2S Ultra and VIDAA on Hisense PX4 Pro. Check the exact US model and required apps, rather than a similar name or older generation.
What matters in practice
JMGO O2S Ultra needs 1.4 ft from lens to screen for a 120-inch 16:9 picture. Hisense PX4 Pro needs 1.7 ft.
Width = diagonal × 16 / √337. At 120 inches the width is 104.6 inches. Multiply by each documented throw endpoint and divide by 12 for feet. This excludes digital zoom, keystone, cabinet offset and lens-shift limits.
JMGO O2S Ultra lists 3600 ISO lumens, while Hisense PX4 Pro uses 3500 ANSI. We do not turn different labeled standards into a brightness multiplier.
Exact published inputs are 3600 ISO for JMGO O2S Ultra and 3500 ANSI for Hisense PX4 Pro. A percentage is shown only within the same labeled standard. Manufacturer methods, calibration and picture modes can still differ.
O2S Ultra reduces lens distance by 20% at equal image width, while PX4 Pro extends the stated maximum from 150 to 200 inches.
1 - 0.16 / 0.2 = 20%. Published diagonal maxima are 150 and 200 inches. The cabinet-to-wall gap is not the lens distance.
Try your real numbers
The result checks hard limits only. Preferences stay out of the calculation.
For a 120-inch 16:9 picture, the calculated lens position is about 1.39 ft. Your input is 9.50 ft.
For a 120-inch 16:9 picture, the calculated lens position is about 1.74 ft. Your input is 9.50 ft.
Distance is measured from the lens to the screen. The calculation uses a 16:9 image and the verified optical throw range for each exact model.
For an ultra-short-throw model, the gap behind the cabinet is a different measurement. Check the installation diagram for cabinet position, screen height and ventilation.

JMGO, O2S Ultra
A compact high-output UST that needs only a few inches of wall clearance for a 100-inch image and includes licensed Google TV.

Hisense, PX4 Pro
Hisense's 2026 premium UST adds an adjustable iris, a larger 200-inch ceiling and fast gaming to a bright triple-laser platform.
Meaningful differences
| What changes | JMGO O2S Ultra | Hisense PX4 Pro | Why it matters |
|---|---|---|---|
| Optical throw ratio | 0.16 to 0.16 | 0.2 to 0.2 | Distance is measured from the lens to the screen, using the image width. |
| Lens distance for 120 inches | 1.4 ft | 1.7 ft | Calculated for 16:9 with optical adjustment only. Cabinet depth and cable clearance are extra. |
| Published image-size range | 80 to 150 in | 80 to 200 in | A supported maximum does not guarantee a bright picture in your room. |
| Published light output | 3600 ISO lumens | 3500 ANSI lumens | Different measurement standards and picture modes are not interchangeable. |
| Display architecture | single-chip-dlp | single-chip-dlp | Single-chip sequential color can matter to viewers sensitive to rainbow flashes. |
| Streaming platform | Google TV | VIDAA | Confirm the exact US edition and the apps you need before adding a separate streamer. |

JMGO lists up to 150 inches and PX4 Pro up to 200. Confirm screen and mounting dimensions before choosing a larger future picture.
Both are ultra-short-throw models. Wall flatness, the screen type and the projector height affect alignment, so a short distance alone does not make this a drop-in TV replacement.
