Questions about this item

How does the 0.1 ms response time hold up during extended gaming sessions?

The 0.1 ms response time is a panel specification and does not degrade with sustained use; motion stays sharp for as long as the TV is on.

What are the heat and fan-noise levels when the TV runs all day?

The OLED panel has no fan and runs silently; surface warmth is typical for self-lit pixels under continuous load.

Which external devices are needed to reach 144 Hz on the four HDMI 2.1 ports?

A PC graphics card or game console that can output 4K at 144 Hz over HDMI 2.1, plus an Ultra High Speed HDMI cable.
