Samsung LC34J791WTPXXU/CJ791 34" Ultra WQHD Curved Monitor With Speakers
Connect to Infinite Possibilities

Thunderbolt™ 3
World’s First Thunderbolt 3 Curved Monitor
The CJ79 features two Thunderbolt 3 ports to connect compatible Macs and PCs. Thunderbolt 3 transmits video and data at speeds of up to 40Gbps — 8 times faster than USB 3.0 — and simultaneously charges devices (up to 85W), all over a single cable.
Curved for Comfort
The curved screen is engineered to follow the natural curve of your eyes for a more immersive and comfortable viewing experience. Studies by Harvard Medical School and Seoul National University Hospital found the screen reduced eyestrain in users compared to flat screens and less curved monitors.
34” Ultra-Wide Screen
The 34’’ ultra-wide curved display with its 21:9 aspect ratio provides all the workspace you need to multi-task efficiently and in comfort. Forget about inconvenient dual monitor set ups and experience truly seamless multitasking on a single screen.
Multiple Inputs
Two Thunderbolt 3 ports as well as, DP, HDMI and USB inputs, the CJ79 provide multiple connection options for PCs, consoles and external devices. And the built-in 7-watt stereo speakers offer an enhanced entertainment experience when viewing videos and playing games.
PBP and PIP
Picture-by-Picture (PBP) lets you display to two sources onscreen at their native resolution. And for optimal multi-tasking, with Picture-in-Picture (PIP) you can resize the second source to up to 25% of the screen and position it anywhere.
Quantum Dot Colour
Supporting up to 125% sRGB colour space, Quantum Dot technology delivers not only more hues than conventional monitors but also colours that are brighter, crisper and more natural — especially reds and greens. And every monitor is factory calibrated to ensure the most accurate and life-like images.
3000:1 Contrast Ratio
Samsung’s VA panel technology provides a 3000:1 contrast ratio that delivers deeper blacks, brilliant whites, and richer colours for clearer, more vibrant movie and game scenes.
AMD FreeSync
AMD FreeSync synchronizes the refresh rates of your graphics card and the CJ79 to minimise image tearing and stutter. The smoother transition between image frames provides seamless gameplay and video playback for uninterrupted viewing.
7W Stereo Speakers
The built-in 7W stereo speakers provide a powerful soundstage for you to enjoy all your music, movies and games in rich, clear sound while also saving space on your desk.
Smoother Gameplay
The fast 100 Hz screen refresh rate provides smoother, silkier mouse sensitivity for enhanced productivity in any application. It also reduces screen stutter in fast-moving action scenes for a flawless gaming experience.

SAMSUNG SMART SIGNAGE STARDARD
WARRANTY GUIDE
SMART SIGNAGE
1. Warranty Term
Samsung currently provides a 3 year standard limited warranty, but the warranty period may vary by country. Please contact your local Samsung representative to check the standard warranty period applicable for your country.
Customers can purchase an extended warranty service pack, which must be purchased when the Product is purchased. The extended warranty period can increase the warranty period up to a total of 5 years.
2. Warranty Description
Samsung warrants that the Product will be free from manufacturing defects in material and workmanship during the abovementioned warranty period and fit for being used as commercial digital signage.
During the warranty period, Samsung will, at its sole discretion,
1) provide service via phone, mail, technical support website (ex. Service Cloud) or e-support access to Help Desk to assist in resolving issues. Phone support is available during normal business hours.
2) repair (at Samsung’s own or Samsung’s Authorized Service Center(ASC)), or replace (using new or refurbished replacement parts or Products) any defect within a reasonable period of time and free of charge.
Generally, On-Site Repair Service is the default service for any Product requiring repair during the applicable warranty period. However, depending on the installed Product, location, environment and any special contract terms, there could be other services available such as Carry-In or Pick-up & Return.
Service Response Turnaround Time (“TAT”):
The average TAT for Service Response is D+1 business days. Service Response means first response to a request (phone, e-mail, technical support website and / or verbal).
Service Response may take more than 1 business day depending on the case.
Service Repair TAT:
Service Repair means initial repair activity by Samsung or Samsung’s ASC.
※ Initial repair activity means one of below activities; site visit, checking symptoms, defective part exchange, configuration adjustment, etc.
Samsung shall aim for a Service Repair TAT of D+5 business days, provided however, additional time may be required, due to, by way of example, limitations in transportation/personnel availability, inaccessibility of location, locations requiring special access authorization (i.e. duty free stores), repeatability of the problem, and inaccurate description of the problem provided. Samsung will use its best efforts to solve the problem during its first on-site visit.
In the event Samsung experiences or foresees such delay, Samsung shall notify the customer and the Parties shall discuss in good faith to arrive at a resolution including a new delivery schedule.
Samsung recommends that the customer maintain a buffer stock of Products to minimize downtime.
3. Warranty Coverage
This limited warranty begins on the original date of purchase, and is valid only on Products purchased directly from Samsung or through Samsung’s authorized partners. To receive warranty service, the customer must contact Samsung for problem determination and service procedures. Warranty service can only be performed by a Samsung ASC. The original dated bill of sale must be presented upon request as proof of purchase to Samsung or Samsung’s ASC. In the event that no proof of purchase can be presented to Samsung, the limited warranty will commence from the date of manufacture specified on the Product.
All replaced parts and Products shall become the property of Samsung and must be returned to Samsung. The repaired or replaced parts or Products assume the remaining original warranty
