Welcome to our website! As we have the ability to list over one million items on our website (our selection changes all of the time), it is not feasible for a company our size to record and playback the descriptions on every item on our website. However, if you have a disability we are here to help you. Please call our disability services phone line at 610-265-9493 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

UltraWide Quad HD on IPS Display

The 3440 X 1440 UltraWide QHD display offers amazingly sharp picture quality. Its pixel area is about 1.8 times larger than an UltraWide Full HD 21:9 monitor, and about 2.4 times larger than a Full HD 16:9 monitor. With IPS, color reproduction is improved and users can view the screen at virtually any angle.

Thunderbolt 2.0 (x2)

Two Thunderbolt input/output ports allow you to connect compatible devices to move data between them with incredible speed of around 20-gigabits-per-second throughput in both directions. 4 times faster than USB 3.0.

sRGB over 99

With over 99 coverage of the sRGB spectrum this LG monitor is a great solution for professional photographers, graphic designers or anyone looking for highly accurate color.

USB 3.0 Quick Charge

Save time when you power up the battery of a connected device using USB 3.0 Quick Charge. Once enabled, this convenient feature allows a phone or other mobile device to charge up to four times faster than regular USB 3.0.

On-Screen Control

On-Screen Control puts a host of essential monitor settings into a handy window for quick, easy access. Volume, brightness, picture mode presets, Screen Split 2.0 and Dual Controller and more can now be adjusted with just a few clicks of the mouse, instead of hard buttons on the monitor.

Screen Split 2.0

Customize your monitor layout for multitasking with the latest version of LG Screen Split. Resize and display multiple windows at once, with 14 options including four different picture-in-picture (PIP) choices.

Easy Setup

Select LG monitors are easy to put together with a simple press-and-click display-to-base attachment. The monitors provide comfortable viewing with versatile screen tilt/height adjustments.
