4K LED TVs and 4K QLED TVs are noticeably better than 1080p; however, QLED technology offers a deeper, richer range of cinematic colors and superior blacks, as well as Dolby Vision support. LED TVs also use a backlight to illuminate pixels, while and QLED TV's pixels emit their own light, which can be controlled by each individual pixel. That control level is what enables QLED to produce true cinematic colors. In terms of which display is right for your needs, that can be answered by the content you plan to show on the display. If your content is produced at television quality there is no better way of displaying it than on a 4K QLED TV. Speak with your eTechnician and they will help you decide what will be the best way to display your content (or even help make your content show better on whichever monitor you choose to rent).
