It's the time taken between pressing a button on a controller and the input to register/become visible on the screen.
This is only applicable if you play video games. Normal TV viewing is unaffected.
High input lag = not good for gaming.
This set has 51 ms of input lag in game mode.
I'd say anything over 16 ms is too high for competitive gaming. 32 - 45 ms is usable. Anything over that is quite unbearable unless you're a casual gamer who's more in it to take part.

Would this be any good for gaming?

input lag is the time it takes for the screen to respond to information received. in this TV's case about 165ms. I would not recommend it for gaming based on my experience. The manufacturer has said they're looking to improve it in firmware updates but bear in mind the US version of this TV still suffers a 50ms lag in it's specific "game" mode. 50ms is playable but feels a bit floaty IMO, especially if using a mouse.

Where have you found the input lag times for this model?

Netflix 4k compatible, hdmi 2.0, usb 3. That's a lot of tv for the money. Also richer sounds specs state a response time of 9.5?
which states "grey to grey" response time of 9.5ms. Hopefully someone more technical than me can clear up the contrasting response time numbers.

Right, not on my phone now so I'll go through my own experience.
I bought one of these TV's when they were on offer at ebuyer, I had to send it back for a refund due mainly to a defective panel (screen corruption) but also due to the high input lag.
The US version of this screen does indeed have a 50ms input lag in "Game" mode. That screen is Android based however and the EU version is opera based from what the manufacturer told me. I measured the input lag in all modes at 165ms using a dual display setup and a fast shutter speed on a camera.
Speaking to the manufacturer they told me they were looking to address the input lag in future firmware updates and bring it in line with the US model, I do not know if this has been done yet.
Outside of my panel problems the screen was clear and the colours good. Sound was good too, but there was some syncing problems due to the input lag which means you need to fiddle with the audio offset to get it working right.

God bless Google! Grey to grey is the new way of measuring response time, so the figures quoted above are probably black to white - which is always higher and a truer representation!
My 6 year old Toshiba has a grey to grey of 8ms, so as a gamer this probably isn't for me. Great price for non gamers though!

I recently experienced a Hisense television set before it was swiftly returned. Would you credit it — the user interface was littered with spelling errors and grammatical difficulties. Truly an intolerable experience — almost as if I were still browsing HUKD.

Sorry, I am a bit confused.
If I have this TV and a PS4.
Surely my PS4 Controller is linked to my PS4 Console.
My PS4 is connected via HDMI to the TV.
If I press a button on my PS4 Pad, isnt it linked to the Console and not the TV itself?
Or do you mean the hdmi input is laggy?
Thanks

This. It's the lag between the tv receiving an image from your console and that image appearing onscreen.
The TV has to process the image it's being sent by the PS4.
This processing time accounts for the input lag figure.
So for example you press the shoot button, the console instantly knows you've done that and sends that signal to the TV. The TV then takes time to process that signal/image and show it on screen.
This is what we call input lag. The amount of time an input takes to be translated to an onscreen action.
I hope this clears things up.

Thank you for that! Yes helped !
I see, than this TV is no good for me :disappointed:

Response time or anything like grey to grey is a useless measurement. All LCD panels preform about the same. They tend to blur with fast motion.
Input lag is useful and ideally you want about 30ms or less for gaming.

People keep on going on about the gaming lag on these TVs but I have this tv, I purchased it from Amazon on a lightning deal for 450 a month ago and it's a great tv. I also have a PS4 and have not found any issues with it at all. The only thing that was funny about this tv was the lip sync was out while watching sky but this was corrected easily in the TVs settings. Its an amazing tv for the money and the picture and sound are amazing.

This review clocked the input lag at 38ms in which is fine for gaming unless you're literally world class. Also if you're looking for a screen with less than 16ms input lag it's probably going to be 1080p, 32" max!

My setup has a Virgin Media Tivo box going into an AV receiver with the audio going to surround speakers and the video going to the TV via HDMI. So, if I was to get this TV, does this mean I'd have a lip sync problem between the audio and video which can't be corrected by the TV's delay settings? I'm not sure if the receiver has a delay setting in its options.

Oh, and 50-inch 4K TVs are still pointless:
This processing time accounts for the input lag figure.
So for example you press the shoot button, the console instantly knows you've done that and sends that signal to the TV. The TV then takes time to process that signal/image and show it on screen.
