LG 49uh750v lag issue

[Nicklas]

So I have a HDMI connected to my smart TV from my computer, watching cmore before bedtime.

I dont know why, but when playing via cmore (or other media) it gets laggy on my TV, if its a panning movie-scene, it lags very clearly, stutters or what its called

Is this "input lag" or what is it? Can I prevent it?

(doing the UFO test the 60Hz is stuttering too)

My damn TV is supposed to handle 120Hz if I am not misstaken)

Seems very weird to have a 2017 Smart TV that cannot handle a simple movie from my computer...

(I have HDMI 2.0 cable)

that is wha happens when oyu hve ghosting, low refresh rate tv with fast moving imags, ideally a 100hz tv or higher can fix that

otherwise, enjoy your lg tv as it is

saying that having 3 samsung tvs doing the same as your lg

Ghosting is not lag or stuttering. Ghosting would be an after image, a trail from movement. Higher hz does not help ghosting which is caused from slow response times. Btw input lag is from input devices, ei keyboard and mouse. It's a delay when clicking or pressing a key and when it finally shows on screen.

It sounds more like the pc is lagging. What are the specs?

 

[Nicklas]

So many words

I do know that my display is automatically lowering the hertz when the TV is turned on, for some reason, the tv is supposed to support 100Hz (not 120) but it drops down to... I dont know really, 60 I guess, as a regular gamer i can feel the difference between 60 and 144, and its definally lower than 100, thats for sure

PC specs:
GTX 980 Ti
16GB RAM
SSD and M.2 SSD
i7 6700k 4.20GHz

Also, the display is getting the same (ghosting?) issues as the TV, when its on

(in Nvidia control center its displaying that the TV only supports 30Hz... wtf is this)

Are you using the same cable? Try a different port on both the tv and monitor?

It's trumotion 100, that's interpolation. It's 60hz.

The thing is i have a male-female connector between two cables, both high speed but one is ethernet and the other is with ARC, I dont know if that screws it...
And the cables total is around 7 meters
I have ordered a 7.5m 2.0HDMI cable that is all in one, see if that helps

Interpola...trumoti.... wat? I have NEVER heard of this, so when does 100Hz actually gets used?

 

[k1114]

It could be the cable but there's no way to confirm unless you have another one to use. It could also be a port issue too but you'd have to use a different port. Most monitors have dvi and come with a dvi cable.

Only certain movie players on pc will allow the trumotion featured to be on. For the most part, just treat it as a normal 60hz display because that's all you're inputting.

I will recieve the new cable this or next week, and I could try another port, but only have one HDMI on my GPU (GTX 980 Ti) rest is DisplayPorts (i guess a adapter HDMI>DP is even more risk for problems)

I guess Cmore is 60Hz only

But, the TV limits the Hertz to 60, and my GPU says its 165 (I have a overclocked monitor), should I manually set ALL the settings to 60Hz? Not just assume it will work correctly automatically?

I still are unsure if the hertz talk is the issue though, if something is panning on the TV, or a person walks at same speed, or they move the camera "cinematic" it will stutter, thats the real word for it, stutter.

 

[Nicklas]

Now when switched the HDMIs on the TV ports the whole [] TV shuts off randomly, just when having it on, duplicating the monitor

It goes total black (not even blacklighted) and then goes back, sound dissapears too

Do I have a shitty TV or wtf is going on?

If this happens after buying the single HDMI cable, that guarrantee works, I should make warranty on this stupidly expensive crap TV?

 

[Nicklas]

What I dont understand is that the regular monitor gets the same problem as the TV, stuttering, alot...

 

[atljsf]

then the stuttering is not thanks to the refresh rate, is something else, of gpu and cpu are slow for what you ask or you have a different problem than the ghosting, the lag we talked in the first place

 

[k1114]

If you really are oced then the frame skipping test would not be showing you running at 60hz. A failed oc can cause frame skipping but now I'm also wondering what other settings you could have messed with that will cause issues. You need to set everything back to default.

 

[Nicklas]

What do you mean with everything to default? Where? On the TV or?

I am not understanding what it can be really, maybe the GPU is shit... Would not suprise me, have heard alot of bad stuff regarding ASUS stuff

 

[Nicklas]

The UFO test now tells me "stutter warning" all the time, when having the TV on...

 

[Nicklas]

Please help!!!

 

[k1114]

Waiting on that new cable.

 

[Nicklas]

I just got it.

And it made things several times worse

I got it connected, the screen started up good, but then out of nowhere the TV would not recieve the HDMI signal and just turned black, and nothing I do changes anything

It does recognize it in Nvidia control panel, but no signal works...

What...the...hell?

 

[k1114]

Try it on the monitor? Do you have anything that you know works fine that you can test the cable on?

 

[Nicklas]

Hmm... It is an older TV 32" I have, its very basic, but it has HDMI

I can try it when I have some killing time over

(its a BIG hassle to get the HDMI cable out of the wall mounted TV, and its placed behind plastic holders to look nice so taking away the HDMI cable takes 20 minutes

 

[Nicklas]

Okay, tried it now, the 32" basic TV, no issues with tearing at all, but my super expensive TV, lags like hell

Only problem is the shitty way to pack it down, then go to the store and EXPLAIN this...
"hello my TV is tearing"
"Did you try restarting the TV?"
