## Description

Sceptre’s C345W-2560UN 34-inch 100Hz Ultrawide Curved Monitor - Exceptional Work. Dominant Play. Designed for quality entertainment, Sceptre’s C345W-2560UN’s WFHD display is here. Captivate a larger audience in a room with our 21:9 UltraWide Curved Monitor. Better gaming sessions are in stores. With a 100Hz high refresh rate, gain an edge over your enemies in competitive environments. With our 34-inch Ultrawide Curved Monitor featuring a 1500R Curvature, viewing media and playing games has never felt more immersive. This curved design also allows you to take in more gaming landscape, giving you an advantage when it comes to spotting all threats and opportunities before your competitors. Accurately resembling the contours of the human eye, the curve assists with providing a better gaming session without straining your eyes like a standard monitor does. The curved display also provides a more comfortable view while doing everyday tasks. Blue Light Shift application is also available to reduce the emission of blue light from your monitor, enabling the ability to work, view, and play for longer hours while protecting your eyes from fatigue, irritation, and strain. Powered by a VA (Vertical Alignment) panel that delivers advanced refresh rates, sharper contrast ratios, and stellar viewing angles, these assets make this panel ideal for gaming and artistic pursuits. Alongside an LED display that delivers sharper contrasts between lights and darks while delivering a vast array of rich colors, a pleasing experience with moving images comes to play. With 320 cd/m² brightness, being able to detect subtle and robust color variations is easier and comes in handy when working on creative projects, with remarkably vivid colors illuminating the screen like never before. With up to 100Hz refresh rate, images change faster and smoother than the standard rate, reducing screen tearing and ghosting. With a clear visible advantage in competitive entertainment, the high refresh rate is able to provide better gaming sessions. A fast response time assists with reducing ghosting and blurring, which means keeping the enemy and terrain in focus during action-packed gaming moments has never been easier. Anti-flicker technology is also available to provide a crisper image by preventing the backlight from flickering periodically. Closing the gap between the graphics card and the monitor’s refresh rates, Adaptive Sync is a technology that further assists with eliminating image and tearing in the processing by closing the gap between the graphics card and monitor refresh craters, ensuring they are synchronized in order to provide an extra edge over your opponents. FPS (First Person Shooter) and RTS (Real-Time Strategy), Sceptre’s custom set display settings for gaming, are also available for a more enhanced experience. Find the perfect angle to enhance your work and play performance with our tiltable display. Multiple ports are offered with 100Hz on DP 1 and up to 85Hz refresh rate on HDMI 1 & HDMI 2. Additionally, the VESA wall mount pattern provides you with the option of attaching the monitor to an articulating arm or mounting it on the wall, allowing you to free up desk space at your work or battle station. As a small thank you for joining us in our journey to create and deliver superior electronics, this monitor also features the Sceptre S Light Logo that brightly projects down on your monitor base. With our edgeless design that completely immerses you in all the captivating visuals, gaming at ultrawide has never looked so good.

Review: Una excelente opción como monitor UltraWide - Una excelente opción para quien esta buscando tener un monitor que aumente la productividad con una sola pantalla. La curvatura ayuda a sentirse mas inmerso en el trabajo y la calidad de imagen y el brillo es muy buena.
Review: This is the stuff you see in sci-fi movies and wish you could have for yourself. - First off I must say that this thing is impressive. Not only in size but in power and quality as well. Second, the price tag is what I am most fond of. How many products like this cost LESS than half a grand? Not many, that's what. Onward to the specifics: It has a clear picture and is very wide at that. Whether you intend to do work at home or just sit back, relax and start gaming, it's good for it all. Though I will say, this thing is B-R-I-G-H-T. After using it for a while I got up to get myself a drink and realized that it illuminates the ENTIRE room. One might even say that if configured correctly that it could double as an X-ray machine, so I don't recommend setting it up in the bedroom if you plan to use it while your significant other is trying to sleep. Thankfully, there is a blue-light setting to help one ease eye strain if long hours in front of the screen (especially in the dark) are either highly likely or just straight-up unavoidable, so there's that. This is just after a few hours of use immediately after putting it together though so I can't speak to its longevity. Another thing that I found interesting is that rather than packing an HDMI cable, it comes with a DisplayPort cable but has two ports for HDMI as well as a jack for headphones so I should say it would be pretty versatile. The cords (including power) are all the perfect length as I have a good surge protector (power strip) or two within very short range and have plenty of room if I wish to adjust. All-in-all, I can't see anything beating the Sceptre because it's cheap, effective, generously-sized and appears to be great quality.
