MBP16 Inch HDMI to TV Input Lag(delay) Help/Advise Needed

[Brendonx]

Hi all. Need some advise regarding input lag when connecting my 2019 MBP16 inch to my Samsung tv via a usb-c hub to hdmi.
My mouse was the first place I noticed the delay but because I’m using it for some light gaming as well it’s very obvious in actions that have tight timing.
I’ve done the obvious thing like turn on game mode and turn off additional processing on the tv end and the settings are the same as the consoles I game on. There is still a pretty big difference in input delay however.
I think it is close to 1/10th of a second or maybe a little more than that.
Does anyone have any suggestions to reduce the input lag?
Can your converter box add that much lag? (I didn’t think they had to do any processing to add lag to the hand off?)

fyi, I’m running my Mac in mirrored mode.

Samsung TV.

4K?

1080P?

Hub manufacturer? <---Maybe the weakest link in the equation.

Firmware for TV is up to date?

It’s a 4K tv

I've just spent three days researching 4K TVs to find the monitor i want. Seems to me there is a fairly wide chasm between the different brands in this aspect, and even between the same brand. Maybe you bought the wrong TV? Is it 4K? Is it an older TV? Rtings.com has a ridiculously comprehensive library of TV reviews, and they dont seem to miss a single detail.

I actually bought this tv largely because of the input delay. I’m quite into my console gaming (so much so I didn’t bother connecting an aerial to my tv). I researched it at the time and, on the year it came out, it was the third shortest input delay in the sub $2500 range.
So while I agree that the tv has to be introducing some lag, I’m pretty confident that it’s not the cause of the 100+ms lag.

Its a 4K Samsung NU6900.

I can't remember if the 16" can drive a 4k display at 60hz, but possibly your 30hz hub is introducing the lag?

You gotta try a direct connect without the hub.

Are you feeding your 4K TV a 4K signal/resolution? If you are sending it 1080p, then it will have to upscale - which adds lag. Also, does your TV have a low-latency mode (sometimes known as a gaming mode)? You will want to turn that on. All consumer televisions have lag - they are running a mini OS to process incoming signals, perform up or downscaling, and if it's a smart TV, then you're dealing with additional OS overhead. Regular PC monitors don't have this issue - signal is processed straight to hardware and there is minimal processing in firmware.

I thought refresh rate was akin to frames per second since we left CRT screens? my display isn’t jumpy, rather imagine I played a video of someone clapping on my computer, the sound comes through from my laptop but the video on my tv shows him clapping later than the sound. if I were to watch a mo I’d this way the lip sync would always be 1/10th of a second out with the sound being faster.
I’m more than happy to try a new converter if I’m wrong about that though.

I’m not feeding it 4K but I think that isn’t the cause because my other gaming consoles also don’t feed 4k and the controls are tight with those. I am running gaming mode and turned off all optional processing that my tv offers. (I’ve set up the TV the same as my Xbox and Nintendo switch). I’m pretty experienced with screens so I think it’s not the screen that’s introducing the delay unfortunately (or maybe fortunately so I don’t need a new screen!)

I don't follow this part. Are your Xbox and Switch are connected to your MBP via the same hub? Or are they connected to your TV in some similar way?

A good idea to try connecting your MBP directly to the TV just to rule out hub issues. Might need to get a new cable to try it.

sorry, I’ll explain that better.
I‘m using different physical HDMI inputs for all my devices. None of my devices run through other devices. When I say it’s set up the same I mean my tv processing is set up the same between each of my inputs. I’ve got them all set up to reduce as much input delay as possible. I’m comparing it to my switch and Xbox inputs because I can’t feel any input delay when playing games on those devices but when playing on my mac with the HDMI connected the delay is quite obvious.

30hz adapter...that's the issue

I bought a USB-C to DisplayPort cable as I couldn't get my Samsung 4K monitor to run at 60Hz with HDMI, it is much better now. I don't know if it is an option for you, but if you have a DisplayPort on the display you may want to try, the cable isn't expensive

Ok. Looks like enough people think this is the issue. I must be wrong that the hz is more than just frame rate. I’ll try Getting a new adaptor.

I’ll check my screen as soon as I get home and if it does I’ll probably try this first. Thanks for the tip.

Another tip: usually when you connect the DisplayPort the Mac tries to output audio there. So if you don't hear music coming out of your headphones, or the speaker, go to the Sound menu and select the correct output. Happened to me a couple of times...

don't use the crap dongle. just get a HDMI to usb-c cable and get 60hz out of it. My hyperdrive doesn't seem to have issues with the HDMI on it but just one cable seems better and 60hz is better.
