Backlight leakage

Can someone point me the correct way to identify if my TFT screen at notebook has a backlight problem or not? Should i place the screen at 90 degrees and then by looking straight see no backlight?

 

Almost all panels leak a little, what you're showing is about average. Which model is it?

 

As Brian said, it seems average. But it is hard to judge with a photo, due to varying light intensity settings on the camera.

You will almost always notice some leakage when on a black background and in a dark room. The best way to judge is by usuage. Leakage is most annoying when watching movies, since they tend to be dimmer and most likely you will be in a dark room. If at such conditions you don't see any significant leakage then it is fine.

My screen, which is considered pretty good compared to the market, shows no leakage in normal daily use, when watching movies I can only notice leakage if I search for it. BUT if I have a full black screen and a dark room, then it is there and very obvious.

 

Yeah, the amout of leakage seems alright. As Q & Brian have mentioned most screens suffer from some amount of leakage. If it annoys you too much then it might worth asking for an exchange, otherwise I wouldnt bother about it.

 

The model is ASUS A6JA, its my first notebook with glossy screen, previously i had an older model with the "old" matte screens, but never had checked for backlight leakage...

I attach a new picture, taken last night at totally dark enviroment. TFT screen placed at 90 degrees and picture taken at keyboard level.

I have viewed some movies and the light leakage didn't bothered me much, but again its a new laptop 15 days old so i wanted the best
