I was a bit tense when reading the negative reviews on this product. Have they given and have they improved? Is it a question of HDMI cable? Anyway, the switching from one source to the other (media gateway and PS4 in my case) is done automatically for the PS4. When the two are on, you must manually switcher to access the bridge but otherwise impeccable. But be patient for delivery (almost 3 weeks for me) and I have felt that since one week on 2 sources. I read some reviews that announced a limited period of the product, to test the long term but, in any case, for now it brings me satisfaction for an unbeatable value for money.
