Page 15: Attaching A Vesa Mount
Attaching a VESA mount Spectrum is compatible with most VESA mounting arms and mounts (sold separately). The VESA mount must support the 100×100mm VESA Mounting Standard and should be rated to hold at least 5.0kg of weight. IMPORTANT You might need additional tools such as a screwdriver (purchased separately) when you attach a mounting device. - Page 16 IMPORTANT These are generic instructions that may not apply to your mounting device. Always follow the mounting device manufacturer’s instructions when mounting the monitor to a wall or swing arm. Spectrum comes with four M4×10mm screws. To ensure that your monitor is mounted securely, you may need to use screws of a different length, that may or may not have been provided with your mounting device.

Page 17: Connecting The Power Cable
Connecting the power cable Connect the power cord to the AC adapter and plug the other end into a grounded AC outlet. Then connect the adapter to the DC power connector on the rear of the monitor. CAUTION To reduce the risk of electric shock or damage to the equipment: Only use the power cord and AC adapter that came with your monitor. -
Page 18: Connecting Video Cables
Connecting video cables • Connect one end of an HDMI cable to one of the HDMI ports along the bottom of the monitor, and the other end to the HDMI port on the source device; • Connect one end of a DisplayPort cable to the DisplayPort connector along the bottom of the monitor, and the other end to the DisplayPort connector on the source device;... - Page 19 NOTE The monitor automatically determines which inputs have valid video signals. You can also select inputs manually using the on-screen display (OSD) menu. With so many ports available, it isn’t surprising that not everyone intends to use the same cable types or cable lengths. Our surveys show that because of this, more than half the cables we could have included in the box would have gone to waste.

Page 20: Connecting Usb Devices
Connecting USB devices The built-in USB hub Spectrum has a built-in USB hub that allows you to connect multiple devices to your computer with a single cable. The USB hub lets you plug in many devices at once, even if your computer doesn't have enough built-in ports. -
Page 21: Connecting Peripheral Devices
Connecting peripheral devices The side of the monitor provides one USB Type-C and two USB Type-A downstream ports. You can use these to connect devices such as a mouse, keyboard, phone, external hard drive or solid-state drive, and practically anything that is USB-connected. The monitor can also charge attached devices, at up to 15W through the USB Type-C port, or up to 10W through the USB Type-A ports. -
Page 22: Connecting To The Usb Host Device(S)
Connecting to the USB host device(s) The bottom of the monitor provides one USB Type-B and one USB Type-C upstream port. Either can be used to connect the built-in USB hub to a host device. Connecting both USB ports along the bottom to two separate host devices simultaneously allows you to select which of the connected host devices controls the USB hub from the on-screen display (OSD) menu. - Page 23 NOTE You must connect either one of, or both the USB upstream ports along the bottom of the monitor to the host device (computer, laptop, gaming console) to make use of USB ports of the built-in USB hub. When connected by a single USB Type-C cable, Spectrum may not be able to simultaneously operate the built-in USB hub at its full speed and run the display at its maximum resolution, refresh rate, and color depth due to technical limitations.
-
Page 24: Connecting An Audio Device
Connecting an audio device Spectrum has a built-in digital-to-analog converter (DAC) that sends audio signals from the video source device to the amplified 3.5mm audio jack connector on the rear of the monitor. • Connect the 3.5mm audio jack plug to the audio port on the rear of the monitor to make use of your speakers, headphones, or other audio device. -
Page 25: Installing A Security Cable

Page 26: Setting Up Your Workspace
Setting up your workspace …or setting up your battle station. When setting up your workspace, whether it's for work or gaming, it's important to prioritize your safety and health. This means maintaining proper posture, health, and work habits, as well as setting up an ergonomic workspace with a properly positioned monitor. -
Page 27: Stay Active
Stay active Reposition your monitor as you adjust your working posture throughout the workday. Don’t stay in one fixed posture for too long, but avoid slouching or leaning, and get up to move around regularly. To avoid discomfort and injury, it's important to take regular breaks while using the computer. Go outside, take a few deep breaths of fresh air, stretch, and exercise to take care of your body. -
Page 28: Watch Your Eyes
Prolonged exposure to flickering screens may lead to loss of focus, fatigue, headaches, and blurred vision, especially in individuals who are sensitive to such visual stimuli.

Page 31: Cool Features
Cool features One-cable solution Typically, separate cables are needed to connect your monitor to your computer for video, audio, and USB data. Additionally, yet another cable is required to charge your laptop or other mobile device. With USB Type-C, you can do all of that with just one cable, simplifying the setup process. It's also a neat and straightforward way to declutter your desk from a tangle of cables. - Page 32 IMPORTANT The host computer must be able to support the USB Power Delivery protocol over the USB Type-C connector to be charged or powered by Spectrum. The host computer must be able to support DisplayPort Alternate Mode over the USB Type- C connector to provide Spectrum with an image signal.
