Mouse Click Glitch

@HyperNova227

I had to think on this, my initial thinking was hardware issue, whether that is thermal induced not sure.

anyways to check standard things run a game repair per below

@proxos666 here is the dxdiag

@HyperNova227

What model is the samsung TV ? JS8000 ?

Does this issue occur as soon as you enter fullscreen mode ?

If your in fullscreen at 3840 x 2160(p) (30Hz)  and not 60Hz does the issue still occur ?

It does not occur as soon as i enter full screen mode. However it only happens in fullscreen mode. So when I am in fullscreen mode, and i click either the left or right mouse buttons, the screen goes green and purple and left half side of the SWTOR display enlarges and is the only thing displayed. When i let go of the left or right mouse button the screen goes back to normal. It is really hard to explain.

My television is the Samsung UN48JU6700.

I tested your 30 Hz idea and the issue does not happen with those settings.

but 30 Hz creates a laggy effect when looking around.

I've been playing in fullscreen (windowed) and the issue does not occur at all. only in the straight up fullscreen does the issue occur.

@HyperNova227

If playing fullscreen (window) mode works it might be best to just play like that ?

The dxdiag seems to think native is 30Hz not 60Hz hence why seeing if it stopped at 30Hz

  Current Mode: 3840 x 2160 (32 bit) (60Hz)
       Monitor Name: Generic PnP Monitor
      Monitor Model: SAMSUNG
         Monitor Id: SAM0C44
        Native Mode: 3840 x 2160(p) (30.000Hz)

 Not sure i can be much more help, given it doesn't occur at 30Hz it is something to do with the display side of the house.

I gather you have the HDMI input on the TV labelled as PC etc and tried a different hdmi cable.

You can have a look at the EDID using CRU (Link) , test an override with only 3840x2160 @60Hz listed and see if it persists.
