View Full Version : Are external devices (HDMI, Easylink) able to change picture format and settings?

Hi,

I have a problem.

I have a Philips BD player connected to my 58PFL9955 with HDMI. Easylink is activated on both devices. Latest firmware on both devices.

When using (playing media files, starting NetTV) the BDP the TV often changes the picture format (e.g. to auto fill - my setup was however "auto zoom" before). Sometimes even the screen edges will be changed - I have them at 0 on HDMI inputs.

My question: do BDPs or Easylink or any other HDMI protocol have the possibility to change such settings on the TV? If not, what can be done to prevent an external device to change my setting of the TV?

It's possible, but I've never seen it in real life before. There is an HDMI standard that allows one device to control another. https://en.wikipedia.org/wiki/HDMI#CEC

Hi Alex! :)

I recognize your problem, but it isn't caused by the BDP actually changing any settings on your tv.

It is caused by the tv not recognizing your BDP as a device you've already setup. Sometimes the tv "thinks" the BDP is a new device, so it resets those settings to their defaults (Auto-Fill, Edges at 10 and Smart at Personal).

The positive point in this is that, when you set them to your values every single time that this happens, at a certain point the problem remains gone. This is because, as far as I know, there are "only" three different ways the BDP can identify itself, so as soon as the tv knows the (same) settings for all these three IDs, it will recognize the BDP no matter what.

Easy, isn't it!?... :p

And yet, yesterday it happened again... Those settings mentioned here, were reset to their defaults when I wanted to play a Harry Potter Blu-ray.
I now know the following:

- with EasyLink on there are two ways the player can show up in the Home menu. First of all, it can show itself simply as "Philips BDP", without any so called "Activities". In this case the settings are always remembered, never a problem.
But when it shows itself complete with all its "Activities", i.e. "Play a Disk", "USB", "NetTV", "Computer" and "Configuration", then it always forgets its previous settings: all these "Activities" are individually reset to their defaults every day, when you turn it on.

- Another problem with EasyLink is that sometimes the player completely disappears from the Home menu. This isn't that important though, as simply turning the player on is enough to get it reentered. But, as mentioned just now, when it then shows up with all its "Activities" your previous settings are lost. When it shows up just as "Philips BDP" it still remembers them.

- Without EasyLink, all of these problems are gone: the player always stays in the Home menu on the spot where you put it, now mentioned as "Blu-ray Disk Player", and it also remembers its settings!

So... what exactly is the reason why I "should" use EasyLink?... What are the "big" advantages?... Do you know?... Because if you don't, and I don't know it either, then I will just keep it deactivated from now on. Works a lot better, if you ask me.

Hi,

I think without Easylink you cannot control your BDP with the TV remote.

I think without Easylink you cannot control your BDP with the TV remote.Correct! And why would I want to do that?... :p I always use the BDP remote, which is optimized for its task, so...
The only EasyLink thing I did use, was that I could just turn on the player and the tv would switch to it automatically, just as it does with SCART. Now I will have to switch to the BDP in the Home menu to watch it. Well... too bad. :rolleyes:

Now I'm wondering about the other way around. Of course there is "Pixel Plus Link", that makes sure no picture enhancements are being done twice. If the tv can do the same tricks the external HDMI device (BDP in this case) can do, "Pixel Plus Link" favors those on the tv and disables the techniques on the BDP.

But what if EasyLink is being disabled on the HDMI device, while still enabled on the tv itself? Is "Pixel Plus Link" linked to EasyLink and also disabled in this case, causing possible picture problems?... Or is "Pixel Plus Link" still being used, even though EasyLink is Off on the external (BDP) device?...

Can anyone, Philips in particular, ;) shed some light on this?...

Thanks in advance! :)
