I noticed that when I project my PC to my HD TV via my HDMI cord, my game lags on the TV. This mostly happens when playing games with high graphics quality.
Is anyone experiencing same thing? Please help.
Thanks

Either the HDMI output is not high enough to transfer the high graphic data packets from the pc to the tv or the port of the tv or pc is faulty

I believe the former is more likely

I have tried it with a different cord (DSTV follow come cord) but the result is the same. It's a new TV though

Please make sure your HDMI ports on your TV and PC respectively are working properly

Try another laptop with the TV and see what happens

Thanks, I found the solution. I had to reduce the game graphics resolution

There are several things you have to consider.
1. Resolution and refresh rate. Make sure the TV can keep up with the output from your PC. If your PC is rendering games at over 60fps and your PC tops out at 30fps, the experience will not be too good. Also, if your PC is running games at 1080p, and your TV can only support upto 720p - it won't look good.
2. Make sure the HDMI cable you are using is cable of supplying good signals (display port cable is a good alternative to HDMI).
3. Check your TV's response time, is it fast enough? PC monitors have fast response times compared to TVs, so a TV with a slow response time can have laggy pictures.

For issues 1, and 3 - check your TV to see if it has a "Gaming Mode", which can help in alleviating these issues.

Edit: I see you have found a solution.

It's not advisable playing games with a tv, because TVs usually have a slower response,(usually measured in ms(, if the problem is not related to the response time, then you have to enable v-sync in game settings, it smoothens the gameplay and locks the fps, but if its lagging because of your laptop specs you may have to lower the graphics for optimum performance
