Even though you may have this option toggled On in the C9, the C9 won't even enter into the Instant Game Response mode (LG's word for ALLM: Auto Low Latency Mode) unless you have an output devices telling the C9 that it is capable of it.Hi all,
I am trying to figure out what (if any) benefit the "Instant Game Response" setting is for my C9. The on-screen setup says that "if a connected device does not support Instant Game Response, it may not function properly." So, I have a couple of questions:
1) Does this mean the device directly connected to the C9 must support this (in my case, a Denon X6400H), or anybody in the chain (like my OPPO disc players).
2) I noticed that it was enabled when I turned on the Deep Color setting. I do not use the C9 for gaming. Can "Instant Game Response" be turned off while leaving Deep Color on?
I connect my PC to the C9. My C9 obviously has Instant Game Response turned On. But as mentioned, the lag is quite obvious when moving the mouse around. It feels sluggish because there is a significant lag since the TV is not in ALLM mode. But once I turn on G-Sync capability on the PC for the C9 with ALLM, you can expect to see the 'Instant Game Response' logo appear on the top right of the TV when you switch to that input aka, my PC for this moment. So it's similar to having HDR or Dolby Vision play where you can see the logo to tell you the TV has accepted the mode. And of course, with the TV now in Instant Game Response mode (ALLM), mouse movements and all feels snappy. So it's more for PC use as well as games (which the next gen consoles should also support) as opposed to your typical BD players that see it as something they do not care to adopt any time soon. Maybe in the future.
1) Yes, the device must support or else, the TV won't enter this mode at all. So no. Any device connected to your old Denon (this receiver clearly cannot support ALLM and will drop the ALLM metadata before it outputs to your TV) will not let any devices connect through that receiver and into the C9 let it trigger ALLM on the C9.
2) Yes, you can. But it will not affect anything. Since as mentioned, your TV will show that 'Instant Game Response' logo if you actually have a device that will trigger your TV to enter that mode. Else, it will not bother you at all even if you leave it On or Off.
