Samsung 32'' UE32F5000AW video playback issue and input lag


Hellos to the community

 

First of all i need to say that i'm new to all this stuff and most of it doens't make sense to me but i'm trying to understand.

 

So i bought the TV on the title (Samsung 32'' UE32F5000AW) a couple of days ago and while connected to the PC , my issue is that when playing 1080p or 720p videos from YouTube the video is not smooth at all for a HDTV, i experience lag spikes on the video and generally poor performance. If i play a video from hard disk drive,  then the issue is not that bad but then there slight distortion on the picture quality but i sense that its normal. 

Another issue is while playing games, especially World of Warcraft where i can see choppy movement, feeling like the GPU cannot catch up with the quantity of graphics it has to send to the TV. 

I was using a 21'' Monitor before i switched to the 32'' one, without any issues at all. 

 

My video card is a 7770 ATI Radeon HD and is connected to the TV via HDMI cable. 

 

Until now, I've completed the following troubleshooting steps :

 

1. Uninstalled completely the drivers for the GPU and re-installed using the Windows preferred, issue remains. 

2. Updated drivers from 13.9 to 13.12 and then 14.1 BETA, issue remains. 

3. Switched the monitor to Game Mode, issue remains and picture quality reduced significally.

 

My generic question is this, where should i turn to? The Cable, the GPU manufacturer, the TV manufacturer or all of this is normal for a TV connected to PC? I used to own a 5 year old LG 32'' LCD TV before and i never had any issues with lag spikes or display lag. 

 

Can anyone share his lights to the matter please? 

 

Thanks in advance,
