USB to Cat 5/6 adapter or USB extender with USB hub - both at 25ft, which would have less input delay for gaming?

post #1 of 3
Thread Starter 
I'm trying to run a 25 ft USB extender or USB to Cat 5/6 adapter from my PC in the room to the TV in the living room. My main concern is in regard to input delay / latency at the specified length not data transfer speeds.

I'm planning to attach a wireless PS4 game-pad, wireless keyb/mouse to a hub at the end of the adapter going into the living room, and then use a separate 25 ft HDMI cable for video.

I already got word on the 5 meter limitation for USB 2.0, which requires either a USB hub or repeater for a smooth signal, but again, my main concern is input delay.

Does anyone have hands on experience testing these two methods side by side? Which is better?


I'm looking at these items:

Any input would be greatly appreciated.

I've personally used USB to cat5 converters over 100ft of cable with a powered hub on the end to run a game-pad and mouse/keyboard on a with no noticeable latency over direct connection to the computer.

I would go with the USB repeater with a powered hub on the end as its USB 2, so you don't have to worry about running out of bandwidth as it can be a concern if the USB connection is only at 1.1 speeds. This way you can plug a thumb drive or other device into the hub without worry.

Extra latency added by the repeater should be on the order of 10s of nanoseconds, but will greatly reduce the chance of the connection glitching out due to noise (eg: microwaves, cellphones, etc). There are much greater sources of latency than what the repeater will add (if you mouse is running at 1000hz, its still introducing 100x more lag than the what the repeater is adding).
