So here's a question:


It's a given that plasmas should be calibrated for each input source (DVD, cable, satellite, etc.) since each component's output is usually different from the others (and sometimes there's variance from a single source depending on resolution). So given that, what will happen when multiple sources are fed through an HDMI-switching pre/pro (e.g., the Anthems when they're upgraded) and fed to the plasma via a single HDMI cable?


Thanks for any insights!

I had the exact same thought. Maybe if you are connecting 2 HDMI devices, one of the output devices (example DVD Player) will have picture adjustsments - and then the DVD player can be set to match the other device.


Another option is to still run componenet connections to the TV from one of the devices and only the HDMI connection for the audio. Kind of defeats the purpose of HDMI switching though.


Seems like there would be a need for different settings within the HDMI TV input.

Not just plasmas, but all displays should calibrate different inputs to their specific source.


With digital switching (DVI and HDMI), you can always use the displays input memory function. I'm not sure about other brands, but Panasonic's commercial series has 4 memory settings (Cinema, Auto, Standard and Dynamic) for each input. Since each of these can have its own settings, you could use the Cinema memory and calibrate for the DVD player and the Standard memory and calibrate for the STB -- all on the same input.

Thanks for the info. I just read through the JV PD-42V475 manual and it has several modes also: Standard, Dymanic, Theater, Video Game.


Another concern resolved - Thanks!

Fujitsu plasmas have 8 memories. You can select the settings in any memory for use with any input.


Display memories aside, some folks have multiple sources that each have their own level setting controls. So, for example, you might calibrate your input for a source with no controls such as an HDTV tuner, and then use the controls inside your DVD player to adjust it so that it will work with that same set of display settings when switched into that input.


Personally I think it's best to keep such calibration adjustments within the display just to minimize the confusion factor. That is, keep all your source devices at their default settings. With a reasonable, programmable remote, it's no big deal to add a display memory selection command into the same macro that switches your receiver or other input device switcher.


With HDMI devices, you might just luck out and find that one set of display levels happens to work with the default settings on multiple source devices. It may just be a fluke, but the HDMI devices I've tried so far all seem to be VERY close if not identical in the level settings they need on the display, given they are set to a common resolution. This is by no means the case if they are hooked up via component.

Thanks for the info.


All these solutions to my questions makes it all the harder to not pick up the phone.


In regards to HDMI switching, are people looking at the switch box in Bruzzi's faq post or waiting for a receiver/pre-pro that has the switching capability.


Also does anyone know if Comcast will have a hdmi stb or possibly a hdmi stb/dvr?

I sent my local cableco an e-mail specifically requesting the HD DVR model number - I was pleasantly suprised when they responded with the info. Astound uses the SA83000HD which includes HDMI. So try sending comcast support an e-mail requesting the info. Also search the avs forum on HDTV recorders - you may find you answer there for your local area.

One problem you may have is with a source that is SD vs another source that is HD being input into the switcher. An HD tuner will output the signal based on High Definition colorspace, but the majority of DVD players with digital outputs that upscale do not do the conversion and the display -- seeing an HD resolution signal -- decodes the SD colorspace signal based on the HD colorspace curve. Colors can look a bit off in this case.
