I am having huge problems getting my LG to work properly with my 895.

There doesnt seem to be a discrete input code for HDMI2, which is the input I use for my DVD player. HDMI1 is used for my HTPC, so I can't simply switch the input.

It seems that the only way to get to HDMI2 is to send the HDMI code twice, which doesnt work if the TV is set to HDMI1 already - it switches to HDMI2 and then back to HDMI1 again. I thought about switching it to another source, pausing, switching to HDMI1 and then HDMI2, but that takes a seeming age and is not the neatest way of doing things.

Does anyone know a way to circumvent this? Surely LG put a discrete code for HDMI2 into the TV? All of the other inputs appear to have discrete entries.

Cheers

D.

The usual solution is to set it up as HDMI1 then include an "inputnext" as "Additional Command when activity starts". Not all devices have discrete codes, and not all that do have a complete set.

As per your description, it also seems the "InputHDMI" command is a toggle not a discrete command. Try all the input commands in device mode paying attention to their behaviour (discrete vs toggle/cycling). In the LG Model 42-PC1D device dataset, I see the "InputHDMI2" command. Its default adjust input settings is set to Method 2 (discrete method) and uses the "InputDVI/DTV" command for the HDMI1/DVI labelled input and the "InputRGB/DTV" command for the "HDMI2" labelled input. Don't confuse input label names with input command names.

So the HDMI2 command that OP wants is shown as "InputRGB/DTV"?
Enough to confuse anyone!

Yes, and the OP will have to carefully write down (document) the action of each input command.

.... and then match the list of actions against the list of commands in Method 2, re-ordering and removing them as necessary.

Method 2 does NOT require re-ordering nor removal of surplus inputs because it uses discrete commands, but cycling methods like Method 1 would.

The options to delete and re-order are available in method 2 but the next page is more important.

Urgh. I'm horribly confused now! You guys are quite obviously experts in these matters... I'm going to have to go over this slowly and try to figure out what to do. I did go through all of the different input buttons when it was in device mode, and noted that the labels rarely reflect what actually happens when you push the buttons. Why is that - surely this TV is common enough that the codes should have been entered properly the first time? Who is it that uploads the codes to Logitech in the first place? Is it possible that the same model of TV would have a different remote in a different market, leading to this issue? I had presumed that in fact the same remote would be used for multiple TV models, meaning an even greater installed user base and therefore wider usage.
I think I'll follow the tip of adding the inputnext doofer when starting the activity. I had tried that once previously but didnt quite get it right.
Thanks for the help guys

If you have only the one problem, getting to HDMI2, then the doofer is the answer.
At "Additional commands when activity starts" include InputHDMI1 and InputNext as commands.
I did this at first for my Tosh but eventually someone found a single discrete, so you may be lucky.
The codes, especially the extra ones, come mainly from users, and gradually become more complete.

Like Hhatkin said, most of the extra commands, specially the discrete ones, are added by users. Since most OEM remotes don't have discrete commands (because they would take too much button space on the OEM remote), most discrete commands are added by users via a Pronto code with fingers crossed. If the added command did not work, then there is no provision to delete it. One has to wait for the database police to clean up the mess. Also, some commands may work only on newer models or work differently on some models. That is why it's important for you to document the behaviour of the commands for you particular model. If you find that many discrete commands work, then use the discrete method (Method 2) along with adding one or more InputNext command(s) in the Activity Start macro feature when needed. Always look for the nearest discrete command requiring the least amount of InputNext. If you find that nearly none of the discrete commands work, then maybe you should select the cycling method (Method 1), but with method 1 (cycling), make sure the number and order of inputs are correct and answer all the questions properly.
