Weird lagging with PC games using my Panasonic TC-P50s60

If you unplug the hdmi connecting too your TV and solely use the monitor, do you have the same problem?

If your pc doesnt run into any issues using your monitor alone, i dont see it being a problem with the pc

Please answer my question, because no one here (unless they have had the same experience) can help you, so please answer this

You have a monitor and tv, unplug the video cable leading to your tv and test your pc with your monitor, Do you have the same issue yes/no

I cant help you if you dont answer it

@murraya

in case you were blind... they did answer your question. also please do not assume you are the only person who is able to offer assistance as you very well know this is not true.

@op

would it be possible to temporarily move the pc to where the tv is located and to use a shorter hdmi cable? (keeping just the tv hooked up without the monitor at the same time)

does this fix the issue at all?

what i find odd is how you say everything works fine and then you start getting issues after the fact. can you explain more in depth when this happens? for instance can you play the game normally for X period of time and then all of a sudden it starts lagging or are you inferring something else?

please list your computer hardware specs as this could help us determine if there is an issue. (what cpu, gpu, psu, mobo, etcetera)
also please do list if your gpu is a reference design (single fan) or non-reference design (multiple fans) and if it is overclocked.
please also list your system temperatures and how many fans you have installed in your case of what size.

do you play games with a console or any other device on the tv? does it lag?
do you have a laptop or other computer with hdmi output you can test with the tv on some games?

emm, i think you are blind i said "because no one here (unless they have had the same experience) can help you" doesnt mean i am the only person who can solve their problem, saying so would be ludicrous. Now as for the op answering my question all he said was "it works fine with my monitor" i want to make sure the tv is unplugged at the time he tests, so he has not fully answered my question.

If his pc works fine with his monitor, it is fine, the problem isnt with his pc. If as soon as he plugs in his HDMI cable and there's an issue, there's either something wrong with the cable, the hdmi port on his graphics card, the hdmi port on his tv or the tv itself

perhaps you did not mean it as such however that is how it came across. perhaps a better choice of words could have been used.

in any case... the op clearly said that with both connected the lagging occurs on both. in the response to your question they said the monitor worked fine. by the powers of deduction you can safely assume they meant without the tv connected. i do agree they were a bit vague and a clear answer would have been better though. all you can do is ask for clarification on the point and if they dont answer just leave it go. if they want an answer they will have to provide details (thats how these thing work on here as you know)

it could very well be the graphics card at this point. without further tests (like i suggested he ran above) and more details (like i asked for above) its honestly just throwing ideas up right now.

if it was a cable issue you would typically notice it from the get go (unless his description was off on the effects which i did ask for clarification on)

if it was the hdmi port typically the same as above would be true.

if it was the hdmi port on the tv the same would be true.

this leads me to two possible issues:

something with the pc (graphics card or graphics card software most probable) as being an issue or as you said something with the television (however do remember he states performance is good for a certain length of time which i asked for clarification on). perhaps somewhere along the line there is a failing or overheating component. or perhaps interference.

plugging the pc in via the same port used as the monitor with a new high quality short cable into a different port on the tv should give us some clues.

until the op responds with some more data there isnt much else we can say.
