Whenever I take a photo of my computer screen with my mobile, I see some kind of glitches in the photo. In simple words, the photo is not clean. When I zoom in and out, sometimes it gets clearer.
My TV is an LED one.

It's because your phone's camera sensor captures more pixels than a screen has and it's technically impossible to align your camera and your screen in a perfect pixels grid.

Try to use the lowest MP setting possible on your phone to see if it makes better shots.

Which TV so we can check it's specs but often this is caused by the refresh rate. The screen is refreshed every 24,30,60, etc seconds and can cause these kinds of symptoms due to how your phone capturers the image and where the tv screen is in that refresh process.

In the old days of tube tv's you could actually capture the electron beam sweeping across the face of the tube as it drew the screen. TV's were 24hz refresh rates so even a film camera would capture this.
