This Samsung LFD LFD makes upgrading firmware easy. The simple transmission is accomplished through an image file, using a DVI, HDMI or display port. Samsung’s LFD LFD lets you perform upgrades effortlessly through a direct connection with your PC. Available at AppliancesConnection


A great picture that’s glare-free
Whether you have a story to tell or a product to sell, it’s important that your image is crystal clear. This Samsung LFD delivers just that—even if your display is located in a brightly-lit environment. It eliminates any reflections that can disrupt your ad’s readability, keeping images smooth and visible.

Stay in the loop with DVI-out
Enjoy superior picture quality with a DVI-out interface that lets you share content between multiple LFDs thanks to an easier-to-connect video matrix. LFDs used to have to be connected to the PC individually, but digital loop out allows you to connect them without connecting to a PC. Better yet, the digital loop out produces a single image without any loss of quality, and there’s no need for a separate video signal distributor. It’s easy to install and the most cost-effective way to connect multiple displays.

Brighter lights, better picture
With an intensely illuminated DID panel your message is always in the spotlight. Its high brightness and contrast level make the screen clear and readable in public. In fact, on average it’s 1.5 times as bright as TV screens. Plus with a low operating temperature this Samsung LFD will be completely reliable for years to come.

Easy control goes the distance
With content constantly changing, you need a reliable software solution that lets you communicate with remote displays in a cost-effective, time-efficient manner. Samsung LFDs feature an upgraded Multi Display Control solution that lets you control a large number of monitors through their embedded RS232 and RJ45 interfaces. Easy and intuitive to use, you can control monitors over short and long distances.

A smart sensor that automatically saves energy. (optional accessory)
Stop worrying about the lighting conditions affecting your display. This Samsung LFD adjusts its brightness levels as ambient light changes so your images are always crystal-clear. And while it compensates for low-light and high-light environments, you’ll save energy and stay eco-friendly.

Set a schedule that’s always on time
Keep your monitor running efficiently at all times. This Samsung LFD boasts a smart scheduling feature. The automatic power on / off function allows you to designate time, day, volume, input source and holiday dates. There’s even a convenient on-screen display setting with up to 3 schedules including day and time.

A slide-in design with easy accessibility
Enjoy convenient, quick access to the PC, network or receiver with this LFD’s optional slide-in modular design. It’s discreetly located on in the rear side of the unit. And there are a variety of module options that can be easily combined with the LFD. You can even insert a customized module—whether it’s Samsung or a third party manufacturer.

Enhanced connectivity without extra costs
Create a professional digital display without having to purchase any extras—like a distributor or external equipment. Samsung makes it easy with a display port that delivers enhanced connectivity and an improved display interface. With a simple adapter, you can connect your PC, monitor or TV using an HDMI or DVI cable that’s more than twice as long as standard cables. Discover an easy, cost-effective way to create a powerful display.
