Loewe Aconda 1080i RGB/VGA Syncing Issues

post #1 of 9
Thread Starter 
Hello There,

The RGB/VGA input for some reason only accepts 480P from my computer and even this took some time to set up and the program powerstrip to change to a specific special resolution and refresh rate. Could this be because I am selecting the wrong resolution? What is the correct resolution, refresh rate, etc... to be able to see 1080i via the RGB on the Aconda? There has to be a way of viewing 1080i via RGB/VGA on the Aconda but it just doesn't sync up for some reason. My computer is a Sony Vaio Z, the latest version with a full 1920x1080 LED screen resolution.

Has anyone used Powerstrip to change the resolution to 1080i for a CRT HDTV?

Also viewing Bluray at 1080i via the component input is stunning as is HDTV, but unfortunately through comcast it does not sync correctly to the NON-HD channels. When watching non-HD channels through component input it stretches them, makes them almost unviewable due to the fact that it looks like they have white lines going through it with hardly any contrast, etc... the On Demand channel looks similar since it's not an HD channel, but once I select an HD program or Channel it looks stunning. Any fixes for this?

Thank you!

Anyone? I am sure some of you have been able to figure this out....

Most older displays' VGA inputs are 640X480 only. There probably isn't much you can do about that. OTOH, many of their component HD inputs can be switched to accept RGB (our older Mits CRT RPTV is like this). Check your manual, perhaps yours can be.

But there is a 1080i setting actually through the VGA port, so it SHOULD work since you can select 1080i or 480 in the TV menu under inputs... For some reasonit only syncs whne I select 1080i. I think I need to select the correct resolution and refresh rate for the output from the computer? I don't know what that would be, and I don't have a manual and don't think it would really help?

Some info that may be helpful from:

Q. Can I hook up my Aconda to my computer?
A. The EU Acondas do come in several different versions: with/without a VGA port, with/without TeleText capability. The US has only one version: with a VGA port. If your computer's video card can output VGA (640x480p) then you can use the Aconda as a computer (albeit a bit of a low resolution and slightly squashed looking) display.

Q. Can the Aconda support other computer resolutions? How do I display resolutions higher than VGA (640x480p) on my Aconda?
A. The Aconda's 640x480 resolution is decent for games, but it is a bit of a chore to use the Aconda as a computer monitor for any real word processing, prolonged web browsing, etc. What we need is access to higher resolutions such as 1920x1080i or 1920x520p, however, these are not standard Windows resolutions...

What you need is Powerstrip 3 a very powerful Shareware program for controlling your PC's video card at very low levels. You will also need to have a good Video Card/3D Accelerator like the GeForce or Nvidia chipset based card.

You will also definitely need to check out this Guide to Displaying Custom Resolutions on HDTV posted AVS Forum. It goes into detail on using Powerstrip 3 and the various resolutions avaiable to you. I do not reccomend experimenting blindly on your own unless you really know what you are doing.

Be careful though, incompatible settings CAN PERMANENTLY DAMAGE your Aconda. Make sure you know what you are doing and double check all your settings before applying them. The Aconda Manual lists the Refresh Rate as: 60 Hz, and the Maximum Vertical Scan rates of 31.5 kHz (at 640x480 progressive scan VGA resolution) and 33.75 (for 1080i interlaced HDTV signals).

Make sure you have set these Maximum scan rates in the Powerstrip program and double check to make sure all settings are compatible with these Scan Rates/Refresh Rates, or your Aconda could become a very large and expensive door stop...

I will try it out this weekend and let you know. Thanks for all the great info! Hopefully I can get it synced up via the instructions. wink.gif

So it looks like my video card has a built in feature for custom resolutions similar to Powerstrip. I used the custom resolution settings suggested here: http://www.allquests.com/question/1561003-5/Custom-Resolution-Guide-for-1080i-HDTV-HTPC-POWERSTRIP-RADEON.html but I can't seem to make it work for some reason... Just see coloured stripes on a black screen streaming around. Obviously it's a sync issue, so I am sure if I can find the correct timing details then I can get it done!

So I need the settings for the Horizontal and Vertical: Front Porch, Back Porch, Sync Width, and the hertz I am assuming should be 33.75 Horizontal and 30 Vertical. I tried a few different numbers and they give slightly different results. I need these numbers. It's the ACO9303 (the 30in version of the Aconda that had the Philips tube).
