Connecting it now HDMI=>HDMI with a Sapphire 4670 card. Connects even faster. Only initial problem was setting up the screen size. Had to set underscan to 0 (doesn't tell you this is the "size" function). Works flawlessly at 1920x1080p.

Had to set underscan to 0...ATI does this for years.
So if your TV set does overscan, you don't lose the Start button...

I have tried the TV as primary monitor as well. It must be my DVI wire with the HDMI adapter. Maybe I should just buy a 25' DVI HDMI wire off ************** and see if that works. If not I will just settle for the PC VGA input which I know for sure works and actually looks really good. Is there much of a difference between the picture quality of a PC connected to HDMI vs. VGA? Using VGA I am able to gt 1920x1080 resolution.

Maybe, its the 25' of cable. Can you try a shorter length? Can you try sending a lower bandwidth signal, i.e., 720p.

You didn't mention in your reply if you had to rename HDMI/DVI 1 as "PC". On my TV is is required for the TV to treat the source properly as a PC rather than a consumer electronic device.

I was originally running VGA and I saw no difference when I switched to DVI. The only change was that I did not have to scale or position the image.

I tried 720 and lower resolutions as well as renaming HDMI/DVI 1 as PC. I can't try a shorter wire because my PC is way across the room and the reason I am trying to get this figured out is that I already have the DVI wire that I was using for my old plasma running along the ceiling. If I can't figure it out I will just order a 25' VGA and take down the DVI wire. I am tempted to order and try a DVI/HDMI cable in case it is my adapters being the problem. Is there any other way I can get my TV to recognize my computer as being connected? Any software that can help me? How about any ways to override the TV input settings to get all inputs set as active. I have spent a week trying to figure this out and I am in a wheelchair and I am driving my dad nuts by having him constantly trying different methods to get the TV recognized. Why can't these things just be simple?

I checked the Nvidia site and the specs on their 7300 do not mention it having HDCP. I'm assuming that you were using a DVI/DVI connection to the old plasma, possibly without HDCP? Could it be a problem with a failed HDCP handshake? Sometimes my XBOX360 fails to negotiate an HDMI connection, but I don't remember if the TV greyed out the input or even gave an error message.

You shouldn't have to replace the DVI cable, just buy (yet another) adapter, DVI (female) to VGA (male).

[Edit] I just checked the ATI site and my card doesn't have HDCP either and it works.

So I have a Dell Inspiron 6400 Laptop with VGA/RGB output. I've tried connecting an RGB cable from my laptop to the TV and the colour on the TV screen is slightly off...almost Greenish. Is this normal? If so, is there a way I can correct this? (The same thing actually happened when I connected my aunt's Gateway laptop to her Panasonic plasma display via RGB cable).

The laptop also has S-Video out component but I'm guessing RGB would be the best bet for picture quality (Like streaming HD and DVDs from the laptop to the TV.)

Thanks in advance for any help!

Is it really an RGB port because that's not the same signal as component video. You need to connect identical signals - VGA output to a VGA input, or HDMI output to HDMI input. You cannot connect one output to a different input and expect a proper signal without a transcoder. It'd be like talking German to a French-speaking person.

If you're using the same type of connection at both ends, then the green colour may also be a poor connection, or a mixed up set of cables if using multiple cables.

I seem to remember reading in this thread that some TVs require the VGA port to be given a certain name to make it work properly. If I remember properly, it wasn't documented in the owners manual.

Correct. The VGA port will give you a much better resolution than S-Video.

Thanks for the reply guys, it is a VGA output to a VGA input as far as I know. Perhaps I should try this with another cable?

OK Just tried it again with a different cable, and same results. Also, for some reason, it shows up on the TV monitor as a letterboxed format even though the monitor is 16:9. (The image also appears to be a bit compressed) Any reason for that? Any way to correct that?

Try configuring the display output? (Hint: cright lick on an empoty spot on the desktop).

Thanks Cockroach, it worked! The colouring is still off though, and the image doesn't look too spectacular (the monitor itself is pretty old, a few years, but is still HD capable and supports 1080i and 720p via component, VGA and DVI. Unfortunately my laptop doesn't have a DVI port.)

When a HD signal is broadcast the TV image looks great, with the exception of a blue haze in the top right hand corner. I'm told that has been reported as a problem with LCD rear projection TVs though.

I suspect you could have a bad connection in your VGA connector. May want to try cleaning it.

So I figured it out, turns out I have to actually manually adjust the screen resolution every time I plug in the laptop to the monitor. Not a major problem, but a bit of a pain in the ass. Anyone know of a way I can set it so that whenever I'm using output to monitor it's set to the resolution I need? (When I adjust the resolution for the monitor it does so on my laptop screen as well as the monitor, which is also kind of annoying).

Try downloading an updated video driver/video card mgmt software for your laptop. It may allow separate mgmt of an external monitor, or maybe not.

I connect a laptop on my TV
my laptop has no TV out (acer)
my TV is a samsung projector with component input 1080i
I think to take a VGA cable to component solution

Does someone already try this type of connection

Thank you in advance

Some FPs have transcoders that can accept VGA signals via the component video inputs since CV is not the same as VGA. Some do not - check the operating manual for the FP? It'd be good if you gave us makes/models of all equipment involved.

Your post was moved to an existing thread.

I'm trying to connect a computer with a DisplayPort output to a Panasonic plasma HDTV with VGA input. I also have a DisplayPort to DVI-D adapter but the HDTV does not have DVI input. Does anyone have an idea how best to connect these. Thanks.

Pardon my ignorance but what is a "DisplayPort".?
