HDMI 1 and HDMI 2 | 3840 × 2160 | 60 Hz |
HDMI 3 | 1920 × 1080 | 60 Hz |
VGA | 1920 × 1080 | 60 Hz |
If possible, set connected computers to these resolutions and refresh rates. See the connected computers’ operating system documentation for instructions.
SMART Board interactive displays support full high definition (FHD) 1080p and 4K ultra high definition (4K UHD) resolutions, provided the source device meets the minimum requirements for such resolutions.
Resolution | Pixels | Details |
|---|---|---|
FHD (1080p) | 1920 × 1080 (2.1 megapixels) | Most modern video devices (computers, laptops, DVD players and Blu‑ray disc players) support FHD resolutions. Check a device’s specifications to see which resolutions it supports. SMART recommends a digital HDMI, DVI or Display Port connection for best results with FHD. Although an analog VGA connection might support FHD, the video quality may be degraded, particularly if the VGA cable is longer than |
4K UHD | 3840 × 2160 (8.3 megapixels) | A 4K UHD display has greater pixel density than an FHD display. A 4K UHD display can show up to four times as much visual information as FHD displays. Notes
|
SMART advises against the use of an analog video connection for displaying FHD or 4K UHD because analog video connections can not display high-resolution images with adequate picture quality. If you want to use FHD or 4K UHD resolutions and the source device supports only an analog video connection, you will likely need to upgrade the source device.

Displays can support different refresh rates, typically 30 Hz or 60 Hz. Higher refresh rates can result in smoother, flicker-free video. Drivers rockwell others wanted. This is most evident when using 4K UHD.
Most computers support a refresh rate of 60 Hz. Using the highest frame refresh rate possible will provide a better experience when using the display, provided the connected device supports the refresh rate. If it doesn’t, you may need to set the device’s display settings to a lower refresh rate.
Note
To display 4K UHD at 60 Hz on the display, use the HDMI 1 or DisplayPort inputs. The HDMI 2 input supports only 30 Hz at 4K UHD.
