Low-latency laptop-to-display mirroring for gaming
A tool or method to use a laptop's screen as an external display output with minimal latency (under 1 second) for real-time gaming, when an HDMI input port is not available. Should work around typical laptop hardware limitations (HDMI output-only) without relying on software solutions like OBS that introduce significant delay.

“I wish there was a little delay way to use laptop screen as tv. I have no tv currently but I cant play wii games with an bigger than 1 second delay from OBS. I know this is because the HDMI port is only output and not input. So you have to fake your input to be the webcam input or something as USB.”
CLASSIFIER RATIONALE
The author expresses a genuine unmet demand for a low-latency solution to use a laptop screen as a display output (like a TV) for gaming. They've identified a technical barrier (HDMI input limitation) and are looking for an alternative method. This is a category-level gap, not a complaint about a specific product bug. The context shows they're trying workarounds (OBS, USB input spoofing) but finding them inadequate for real-time gaming.
