A closer look
What matters before you buy
Choose the screen size for its position
This is the 40-inch screen option. Check the full cabinet and stand measurements against the space where it will sit; the diagonal screen size is not its overall width.
Check the inputs you need
HDMI is listed for this screen. Count the devices you want connected at the same time, then check the actual number and capabilities of its ports. An HDMI label alone does not specify every supported display mode.
