Questions about this item

How does the 120Hz refresh rate feel when I am actually watching sports or playing games?

The panel refreshes at 120Hz and the Motion Xcelerator feature can drive up to 144Hz, so fast motion stays sharp with minimal blur during live sports or gaming sessions.

What does the HDMI 2.1 interface actually allow me to connect at full speed?

Four HDMI ports support the latest standard, letting you plug in a 4K 120Hz games console or PC and get the full 3840 x 2160 resolution at 120 frames per second without compression.

What VESA pattern and wall clearance does the 77-inch screen need for mounting?

The set uses a standard VESA mount; check the manual for the exact hole spacing and allow enough depth for the 2.1-channel speaker bar that sits at the bottom of the panel.
