55WH80F

What the 55WH80F is built to do

The Hisense 55WH80F is a 55-inch display made for placement behind a shop window or glazed frontage, where content has to compete with daylight rather than with indoor lighting. The panel is a 3840 x 2160 4K UHD ADS type with a DLED backlight, and it can be mounted in landscape or portrait. It belongs to Hisense's WH80F window-facing series.

Brightness and picture figures that matter behind glass

The headline figure is 4000 cd/m2 typical brightness, quoted without UV. Brightness is only part of readability through a window, so the rest of the panel data matters too. The contrast ratios are 1,200:1 static and 1,000,000:1 dynamic, and the viewing angle is rated at 178 degrees. Hisense states that the image stays visible to viewers wearing polarised sunglasses.

• Refresh rate: 60Hz, with 8ms typical response time
• Colour: 72% NTSC gamut and 1.07G colour depth (8 bit + FRC)
• Haze: 1%
• Panel lifetime: up to 50,000 hours, with operation rated for 7 days by 24 hours

Software, connections and control

The unit runs Android 11 on a quad-core ARM Cortex-A55 processor with Mali-G52 graphics, 2GB DDR4 memory and 16GB eMMC storage. Content is managed through the built-in VisionInfo platform, which lets you create, edit and organise material and control displays remotely. Because Android runs on the display, you can install third-party apps without a separate media player.

Inputs are three HDMI 2.0 ports, one USB 2.0 Type-A port, RS232 and LAN over RJ45, an IR input and an ambient light sensor input. Outputs are one HDMI, one 3.5mm audio and RS232. Dual-band Wi-Fi (2.4/5.0GHz, 802.11 a/b/g/n/ac) and Bluetooth 5.1 are included, along with two 10W speakers.

Where it fits in Qatar

A retail unit on a main road in Al Sadd or Msheireb can use the panel to show offers to pedestrians during the day, with content updated from the office through VisionInfo. A bank branch in Doha's business district can run service messages in Arabic and English, since the on-screen language list includes Arabic. A hotel or serviced apartment entrance in West Bay or The Pearl can present arrival information and event listings at the glass frontage.

Heat, sun and power planning

The stated operating range is 0 to 40°C at 10 to 80% humidity, non-condensing. Summer temperatures in Qatar can climb above 45°C, so a window-facing position has to keep the unit inside its rated range through airflow, shading and control of direct sun. Confirm the exact position with the SmartRooms Qatar team during a free site survey before the display goes on the wall.

Power is rated at 100 to 240V, 50/60Hz, with typical consumption of 180W, maximum 380W and standby below 0.5W. Use the maximum figure when calculating circuit load for several units on one frontage.

Mounting, dimensions and what arrives in the box

The display measures 1232.6 x 704.6 x 57.9 mm with a 9.9 mm even bezel and weighs 27.7 kg net. It mounts on a VESA 400 x 400 mm pattern with four M6 screws. Check the bracket, glazing and wall or frame against that weight before ordering. The box includes a quick setup guide, power cord, remote control with two AAA batteries, RS232 converter cable, IR cable and IR and light sensor cable. Listed certifications are CB, CE, FCC, cTUVus, ERP, CEC and RCM, with EMC Class A.
