is my display the reason for my poor performance?

Background

I sold my rig last year due to moving out which comprised of
- GTX 670, i5 3570k, 8GB LP Veng, Dell U2515h

I have now purchased, off a friend the following rig
- GTX 980, AMD 8350, 16GB LP Veng and the system is hooked up to my Samsung MU6100 4k 55' Smart TV.

Now the build is an obvious upgrade, except perhaps the CPU. I also have no reason to think that any parts are faulty, its in very good condition. The obvious big difference is going from an IPS to a TV.

The Issue

If I zig zag the mouse across the screen, its not very fluid, it seems to skip rather than scroll across nicely. This doesnt bother me but it must be related to the issue caused when gaming.

When turning in a first person shooter like CSGO its horrible. Everythings unfocused, it feels clunky and draggy. I have played around with mouse settings, frames per second seems fine, no dips or anything.

I havnt played for a while so my aim is poor, but this issue means that FPS games are not an enjoyable experience.

Diagnosis

The obvious thing seems to be the TV. I was under the impression that input lag and response times were pretty much okay on these new smart TVs. I enabled game mode which did help a little bit, but not enough to stop you being at a disadvantage in a fire fight.

It would be a shape if I cant game on this TV as I do not have room for a isolated computer setup but as it stands I cant play. Are there any other tricks I can try?

How are you hooking your GPU to the TV? Make sure that the TV is connected to the PC using HDMI 2.0 while in Game Mode or PC Mode (both take away TV processing for reduced input lag). Look into your driver's display settings to make sure you have the TV set up with the correct refresh rate.

I am not sure if its 1.4 or 2 HDMI. To clarify though, watching videos and streams are all virtually seamless. I am not sure if my TV has a PC mode, I had to set it up as a 'console' to be able to use game mode.

Il have to take a look at the refresh rate, could it possibly be lower by default?

I had very similar issues when I connected a PC to my 4k TV. The mouse was not fluid at all and it all seemed very jerky and juddery.

In for the solution tbh. On 1080p it's fine of course, but 4k was no good at all.

I tried to run everything at 1080p (system cant cope with 4k gaming & I dont have a 1440 option?) but it didnt seem to help.

had same problem with brand new Samsung tv it was terrible not sure if it differs from model to model but it was not good the input delay was the problem i switched over to a Sony and everything is sweet as pie,still needs a bit of fine tuning to get the pic just right tho but the lag immediately was gone
can try going into the hdmi ports and changing//renaming them to pc /game mode but it did very little to make any change on the Samsung reading about i saw a lot of ppl having the same problems with Samsung not sure about the newer ones tho

That is because you used the same input dude.

4k inputs are totally different to 1080p. My TV has one 4k input and several 1080p. However, they run from a totally different board.

I first connected my PVR to the 4k input and nothing happened. I phoned the company who make my TV, telling them about it, and they said it could be one of two things. Either the PVR was not outputting the correct signal or the 4k HDMI board was toast. I asked them to explain and they said that my TV had a 4k board with one input and then a separate run of 1080p inputs. I connected the PVR to 1080p input and it worked perfectly. So I figured I would leave it (as I had plenty of warranty) and then one day if I ever used the 4k socket I would get back to them.

I connected my Fury X to the 4k input about 18 months ago. It worked, and was detected as a display (Hitachi or something, basically whoever made the 4k board) but it just stuttered really badly. Just as you are describing here.

I concluded that the TV was probably fine, and it was because I connected a GPU to it that it may not have worked as it should.

From this than I can assume that HDMI 1, is for 4k input, and HDMI 2,3,4 may perhaps be 1080p. I will try those ports as well to see if I notice a difference.

Read the manual fella. If they are all 4k capable then it will be one board only, and they just select..

I asked my TV maker about this and he said that 4k boards were very expensive (mine is an early one) and thus why it only had one input.

But yeah, RTM and it should tell you the properties of the ports

May also help you. It could be the MS of the TV that is causing the lag. Maybe it is much worse at 4k?

Right, I believe mine are all 4k so that is that unfortunately.

I have however set everything back up and surprise surprise, in device manager, its on 30 herts! Boosted up to 60 and now the mouse seems to flow a lot better. I will report back after testing in game.

Hopefully it really is that simple but I shall follow up shortly. Thank you for all the replies, great community.

I did some more reading earlier and it seems the MS input on TVs suck balls, so it could just be that. OK for movies, terrible for anything else... See if your TV has a "Gaming" mode or some other mode to reduce the lag.
