What the Dell C8621QT delivers

The Dell C8621QT is an 86-class interactive touch monitor from the Dell C Series. Its 85.6-inch LED-backlit IPS panel runs at 3840 x 2160 (4K UHD) with a 16:9 aspect ratio, 350 cd/m² brightness and 1200:1 dynamic contrast. The front is 4mm tempered glass with an anti-glare, 9H hard coating, and the panel has a 178° viewing angle, so people seated across a large room can read the same content.

Touch is handled by a 20-point touchscreen. Several people can write, draw or move objects at the same time, using fingers, a palm or one of the two included styluses. This makes it a practical tool for group exercises and brainstorming, where a single presenter would otherwise control the board.

Connectivity and remote management

The monitor offers four HDMI ports, a DisplayPort 1.2 input, a USB-C port that supplies up to 90W of power delivery for a laptop, an audio line-out, three USB 3.1 ports and a USB power-only port. Two built-in 20W speakers provide 40W total output for presentation audio.

For IT teams, the RS-232 port, RJ45 network connection, HDMI CEC ports and TCP/IP command set allow the display to be controlled and checked remotely. This helps facilities teams in government buildings, schools or hospitals keep several screens consistent without visiting each room.

Where it fits in Qatar

In a boardroom in West Bay or Msheireb, the 86-inch format lets a leadership team review documents, dashboards or floor plans at full size, while a laptop charges through the USB-C port during the meeting.

In a lecture hall or seminar room at Education City, the four HDMI inputs let a lecturer switch between a laptop and a visiting speaker's device without repeatedly changing cables.

At a training centre in Lusail or Al Sadd, Dell Screen Drop lets staff of different heights reach the content. The side buttons offer three height settings for raising, lowering and marking up the image.

Planning the installation

The panel weighs 86.5 kg and 114.5 kg in shipping, measuring 198.264 cm wide, 115.663 cm high and 8.28 cm deep. Because this is a heavy wall-mounted display, confirm the wall structure and the 600 x 400 mm VESA interface before ordering. A free site survey from SmartRooms Qatar can check the wall, cable routes and room conditions.

Plan the environment too. The listed operating range is 0 to 40°C at 10 to 80% humidity, non-condensing. Qatar summer temperatures can exceed 45°C, so install the display in an air-conditioned room away from direct sunlight through glass. Maximum power draw is 430W and on-mode draw is 171W. The data lists an AC 120/230 V, 50/60 Hz input, so confirm the power arrangement with the SmartRooms Qatar team given Qatar's 240 V supply.

The box includes two styluses with spare nibs, a remote control and holder, AAA batteries, cable clips, and HDMI, DisplayPort, USB-C and USB 3.1 cables with power cords. The cable lock is sold separately, and the optional Dell OptiPlex Micro PC can be included in your quotation if needed.

Send SmartRooms Qatar your room dimensions, wall type and intended use, then request a quote. The team usually returns quotations within one working day.

Questions about C8621QT

What is the Dell C8621QT used for?

The Dell C8621QT is an interactive touch monitor for meeting rooms, classrooms and training spaces where several people work on one large screen. Its 85.6-inch 4K panel and 20-point touch suit a boardroom in West Bay or a lecture hall in Education City, where presenters and participants annotate and share content directly on the display.

How many people can touch the screen at once?

The panel supports 20 touch points, so multiple users can interact with the screen at the same time. Touch works with fingers, a palm or a stylus. This suits group exercises in a Lusail training centre or brainstorming sessions in a Msheireb meeting room, where a single presenter would otherwise control the board.

What styluses and accessories come in the box?

The box includes two styluses, two spare stylus nibs, two AAA batteries, a remote control with holder, three cable clips and one PC box holder. The stylus has a fine writing tip and a precise eraser, and it attaches magnetically to the side of the display so it is not misplaced during a busy session.

Can I charge a laptop through the monitor?

Yes, the USB-C port provides up to 90W of power delivery, so a compatible laptop can charge while you present. Check that your laptop supports USB-C power delivery at that wattage before relying on it. This is useful in long board meetings in West Bay where laptops are used throughout the session.

How does Dell Screen Drop help a mixed-height audience?

Dell Screen Drop lets the panel be raised, lowered and marked up at three height settings using buttons on the side of the display. In a mixed audience, such as a school with pupils of different ages or a training session with staff of varying height, this helps everyone reach the content without a separate lectern.

Can IT manage the display remotely?

Yes. IT teams can use RS-232, an RJ45 network connection, HDMI CEC ports and the TCP/IP command set to control and check the display. Dell Display Manager software offers Easy Arrange templates and Auto-restore, which remembers the last presentation layout, helping facilities teams run multiple rooms consistently.

Can it be installed in a hot room or near a window?

The listed operating range is 0 to 40°C at 10 to 80% humidity, non-condensing. Qatar summer temperatures can exceed 45°C, so install it in an air-conditioned room, away from direct sunlight through glass and dust-heavy entrances. Ask SmartRooms Qatar to check the room conditions during a free site survey before installation.

How heavy is it and what does the wall need?

The panel weighs 86.5 kg and 114.5 kg in shipping. It measures 198.264 cm wide, 115.663 cm high and 8.28 cm deep, and uses a 600 x 400 mm VESA interface. Confirm that the wall structure and mounting hardware are rated for this load before ordering, and have a site survey completed first.

Does it run on Qatar's 240 V power?

The data lists a power input of AC 120/230 V at 50/60 Hz, a maximum draw of 430W, 171W in on mode and 0.3W in standby. Because Qatar supplies 240 V with BS 1363 sockets, ask the SmartRooms Qatar team to confirm the power arrangement and cord before installation.

Which cables are included?

The package includes a 3 m HDMI cable, a 3 m DisplayPort cable, a 1.8 m USB-C cable, a 3 m USB 3.1 cable and power cords. The panel has a security lock slot, but the cable lock is sold separately. Plan extra cable lengths for sources placed far from a wall-mounted panel.

Can a government ministry or school order it through an LPO or tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs), government tenders including Monaqasat, and payment by bank transfer, cheque or purchase order. When you request a quote, list the quantity and each room so the quotation matches your LPO or tender requirements.
