HDTV Video card suggestions?

dvd_maniac · #1 08-01-2005, 01:19 PM

I currently own an ATI AIW 9800 Pro. I am having issues with using my Hitatchi 57" HDTV as a second monitor. I can get either the TV "OR" my LiquidVideo 17" LCD monitor to have the correct resolution using the YPrPb output. If I use S-video then Clone mode works fine. But I would really like to have better resolution on TV.

My Question is what video cards work good with HDTV and Monitor setup? Should I get another card or another monitor or can somebody here help me out with current setup?

What specifically (resolutions/modes) are you trying to do? It may not be possible.

Shouldn't they act as individual displays?

I am running the HDTV at something like 1140x636 (Custom) and it works fine.
I am running the Monitor at 1024x768 and that works fine too.

But how do I get each to use those specific settings? To tell you the truth, when I enable the Component out to HDTV I do not know what the resolution on the monitor switches to

Do you have an ATI card with an HDTV setup as second monitor?

Depends on how you have it configured, setting it to extended desktop should do what you want.

Try extended desktop, if that doesn't work you'll have to hope for more useful (ie from ATI users) advice.

I've got both (ATI and nVidia), but haven't really used dual-display setups on either much, but nether seem to offer anything the other doesn't.

in extended desktop I can't use overlay can I? the only thing I want the tv to do is watch TV.

stanger89 · #6 08-02-2005, 07:43 AM

Overlay only works on the primary display in that configuration.

dvd_maniac · #7 08-02-2005, 01:37 PM

wow, it seems like ATI has done everything possible to make it IMPOSSIBLE for me to watch videos on my HDTV....

to ATI

Thanx for your help on this Stanger89

Actually, it's microsoft who has put that limitation in Windows. Overlay can't be displayed on two monitors with Nvidia cards either.

Opus4 · #9 08-02-2005, 02:59 PM

Is this overlay limitation for ATI only, for newer nVidia cards also, or dependant on the chosen decoder? I remember this coming up on the forum a LONG time ago & I was told that overlay can only be used on the primary monitor, but I am either using overlay on my 2nd monitor w/my nVidia card or else I'm using something very similar -- it acts just like overlay, including not being able to grab a screen shot of it using the printscrn key. It is not vmr7 or vmr9, nor does it seem to be just some background image where the video is shown, since it can't be captured easily.

I don't think you can clone the overlay, but can't you simply drag the window to the other monitor on the extended desktop & have it show up there? (That's all I'm doing - I can drag it to either monitor & the video will show on either one, but not both at the same time.)

While I don't have a dual-display setup, I do have an LCD monitor with both DVI/VGA inputs, and coincidentally I have a Radeon 9500 with the same

I set it up, extended desktop, and while overlay will only function on one display at a time, it does appear to work on either, I can drag the SageTV window back and forth, and it (the video/overlay) seems to switch sides when the window is halfway across.

This is w/ Cat 5.7 I believe.

dvd_maniac · #11 08-04-2005, 01:07 PM

So can either of you do work on the monitor while watching fullscreen on the TV while using DVI/Component? And is there a problem with overscan on either the monitor or HDTV?

I have tried directly connecting the DVI cable from Video Card to TV but then I lose my VGA output to Monitor (AIW only has one DVI out and I have to use an adapter to VGA to go to my LCD monitor) So I have the HDTV Component adapter hooked up via Component wires to HDTV.

I am not even at the overlay problem. I am stuck on the problem of not being able to have both displays working while utilitizing the whole screen are without overscan issues.

dvd_maniac · #12 08-04-2005, 10:41 PM

Could my problem have something to do with the fact that my LCD is using analog VGA instead of true DVI input? Is that why my monitor seriously overscans when using a resolution that the HDTV likes? and the HDTV seriously underscans when using a resolution that the monitor likes?

Recommendations for a new monitor if needed?

sleonard · #13 08-05-2005, 02:28 AM

Clone mode sets both to the same resolution. The only way to use one resolution for the monitor and another for the TV is with extended desktop.

dvd_maniac · #14 08-05-2005, 04:33 PM

Hi Sleonard

I understand that I need to have same resolution on both with clone mode. My question is what LCD monitor will support 1104x636 without overscan issues? My current LCD has serious issues at this resolution which is the only resolution my HDTV seems to like via Component cables.

stanger89 · #15 08-05-2005, 05:27 PM

Any computer display (save maybe a CRT) will have serious issues with that. LCDs have serious issues with anything but their native resolution.

I doubt you will find an LCD that can handle that resolution. As stated above, they only like to work with their native resolutions. In fact, unless you have a wide screen LCD, chances are you will not be able to display the same resolution on both the monitor and the HDTV at the same time -- one is 4:3 and the other is 16:9.

Does your HDTV work at 1280X720? I would think most should be able to handle that since it's one of the standards.

I assume that's 720p but with overscan correction, ie 1280x720 padded with black so that the active area doesn't run off the screen.

Yeah -- 1280X720 is 720p and 1920X1080 is 1080i.

I know, what I meant was I assume 1104x636 is an overscan corrected 720p resolution. TV sees it as 720p Windows sees it as above.
