How to get my TV to default to HDMi

nollag2006

Bought an Acoustic Solutions box some time ago that i had rigged up to a freeview box.

We recently got satellite in the house, and my other TVs work fine.

However, for this specific TV (http://www.dooyoo.co.uk/television/acoustic-solutions-lcdw22dvd95f/), I am having a problem.

Whenever I turn the TV on, I have to keep pressing the AV button to select HDMI. Works fine from then on.

Is there anything that I can do, such that it defaults to HDMi once the TV is switched on?

Thanks

Afraid not on that one as my Sony TV is the exact same. The HDMI connection does not have a power switch for changing to that input like a scart cable did so it depends on your TV if it will automatically go on to the last source used or not, unless someone knows anything different.

My Panasonic wouldn't auto-switch to the Sky+ box when I switched on and it transpired that it would only switch if the Sky+ box was connected to the HDMI-1 socket. I had it connected to the HDMI-2 socket so a quick cable swop and I was in business.

Joining this a bit late. I have just got a youview box and my Sony TV always fires up on terrestrial TV, so have to switch to HDMI, which is annoying. There is no way to force the TV to do this. Best option is to programme you device remote to control the TV. Youview has a TV and PVR button. You just have to programme the remote to control your TV by entering a two or three digit code specific to your tele. BT has a huge list of these on its website. Worked for me, still have to switch to HDMI, but at least I can do it all on one remote.

HDMI does have a signal function, but it's down to the devices if they use it at all.
It just doesn't (from memory) have a dedicated wire for it, as unlike SCART it doesn't need an separate wire* for every function (in the same way a digital signal doesn't need separate wires for left and right audio), as it just sends a few extra bits down the main wires**.
The problem is that the TV has to actually "listen" to the HDMI ports to know what's going on, and ready for the "change over, i'm ready" signal, in the same way that computers can be set to wake up when you move your mouse or press a button on your keyboard, as well as pressing the main button on the case (older machines often wouldn't wake if you had a USB mouse/keyboard as they only listened on the PS2 ports).

It's sometimes worth going into the settings of the TV and connected devices and checking that they have any HDMI signalling options turned on, with some sets you can turn it on or off depending on what you prefer.

For example with my Samsung TV in the living room, when I turn the TV it it defaults to the last channel watched (usually the V+ box on HDMI1), if I then turn the Blu-ray player on the TV detects that that new HDMI device has powered up and (correctly) assumes I want to watch that, changing the input to HDMI2.
Unfortunately it's not quite smart enough to work out that when the blu-ray player is turned off, I want it to turn back to HDMI 1 again


*Scart is so unwieldy because it has to have a separate wire for every function, in most cases in both directions (so it has 6 wires dedicated to RGB signals - 3 both ways, another 5 or 6 for audio etc).

**From memory if you've got two devices that support it, your HDMI connected TV can control a Blu-ray player, or even PVR via the HDMI control signals, but from what I understand different manufacturers can use slightly different ways to do that, apart from the most basic (input switching) signals.
