1024x768 16:9 Widescreen Display support?

steelydave · May 4, 2006, 05:30 PM

I have a Radeon 9800SE and have just got a nice big widescreen plasma display. Its native resolution is 1024x768, but when I choose that everything is squished vertically because 1024x768 is a 4:3 ratio, and this is a 16:9 screen. Anyway, is there a workaround to use 1024x768 and have it display properly on a 16:9 screen? If not it would be nice to see support for both 1024x768 and 1024x1024 widescreen resolutions in future drivers as I believe more and more people will be asking for this as they get in to the whole HD TV thing.

Dave.

HD resolutions consist of 480/720/1080 (i/p for each)

480 is imo, fairly low quality, basically DVD quality (720x480? is that right?).... with P it's progressive so it looks much better then standard i.

anyways,

HD-720 = 1280x720
HD-1080 = 1920x1080

A true HD tv with a 16:9 ratio shouln't have a 1024x768 native resolution.... not that i know of, but the maximum a TV can support for resolution across normal RCA (composite) or S-Video is 1024x768. You'd need to get the component (RGB) cables and connectors OR a DVI/HD connector for true HD resolutions or higher resolutions.

My TV can accept all the HD resolutions right up to 1080p, but it rescales them internally to it's native resolution (1024x768). Obviously this works, but just staying in native resolution provides much higher quality than digitally rescaling the picture. Currently there are NO 42" plasmas that are full 720p res (1280x720p) - only the 50" models are 720p native, and they are 3 to 5 times as expensive as a 42" model. Go on any manufacturers site (Sony, Panasonic, Philips, LG, Toshiba, etc. and look at their plasma displays and almost all of them are 1024x768 - Philips has one model that does 1920x1080, but it's something like $10,000! All I'm essentially asking for is anamorphic 1024x768 support - the same way a DVD player does. You'll notice that 720x480 is not a widescreen aspect ratio, yet DVD players get around this by outputting a picture that is vertically stretched when they're feeding a widescreen display, that way when the vertically stretched 4x3 picture is displayed on a widescreen display, it's shown correctly because the widescreen display squeezes it back down. That's essentially what I'm after and I don't think it would be impossible to implement - I just don't know who to ask!

I'm not sure about how it works on your setup -- or if it works -- but I've had to 'stretch' my screens a few times after installing new drivers at times.

Somewhere in the CCC is an Adjustments screen that can be used to resize/stretch the image in horizontal and/or vertical. You need to select the 'active' monitor in order to see this screen, I believe.

Whether it can be stretched enough to go from 4:3 to 16:9 I'm not sure, but it should be possible.

So you are using a HD Component cable or HD Connector of some sort and not Svideo or RCA (composite) to connect to the tv?

I know DVDs aren't truely widescreen format, but they are as close as anything else currently availble

i think it's 768x480 or 756x480.... for true widescreen... no?

in any case... Only place to adjust would be in the CCC setup, and you may be able to add 480p/720p/1080p to your resolution selection. If you tv does auto digitally adjust the picture of a hd display to fit your screen at it's 1024x768 native resolution.. wouldn't that be your best choice?
