nVidia DualView - HDTV/PC monitor config

[nintendo_nerd]

So, I recently decided to get a DVI-I to HDMI cable for the Sony Bravia HDTV in order to play games and watch movies off of Netflix. Well, after much research, I've experimented with various configurations; here are the current settings for both displays:

PC Monitor (Primary, 20")
Type: LCD
Manufacturer: Dell
Model: E198WFP
Current Resolution: 1440x900 (WXGA)

TV (Secondary, 46")
Type: LCD HDTV
Manufacturer: Sony
Model: KDL46S4100
Current Resolution: 1920x1080x60 (Progressive, native)

Current PC Video Mode: "Extend these displays" via nVidia Control Panel.

So, to summarize, I have the primary at 1440x900 and the HDTV at 1080p (1920x1080). Here's the situation, there are currently two ways of combating overscan issues on HDTVs; one is use 1:1 pixel (or "Full Pixel") in the TV settings or two, create a virtual resolution via "Adjust desktop size and position" in the control panel. According to this guide http://nvidia.custhelp.com/cgi-bin/nvid ... faqid=2593 it still sends a 1080i/p signal to the HDTV, but creates an invisible border to compensate overscan. Instead of being 1920x1080, it would be something like 1842x1030, but the HDTV still sees it as a "1080i/p" signal. Does it matter what this (customized) virtual resolution is, so long as it still recognized as 1080i/p by Bravia TV? Keep in mind that as of now, DualView works just fine (without resizing), except for the fact that there are settings I have to adjust each time I use the TV, but with the customized resolution, it would correct overscan without me having to change the pixel mode every single time. I just want to make sure I can use said resolution without damaging something. What strikes me as odd is the fact that many "1080p" resolutions don't even equal 2,073,600 pixels (in the Control Panel) or use 1080 lines.


1080 resolutions I can choose from:

1768x922
1680x1050
1600x1024
1600x900
1440x900
1360x768
1280x1024
1280x960
1280x800
1280x768

WTH?

I have a Sony Bravia KDL-32XBR6 I use as my primary and am wondering why you need to change display modes so often? Each input on the set should remember the display mode and switch when you change inputs.

As for your question, that mode should be OK for your desktop but most games will probably override it or not have it available as an option. As for damage? No, not possible, apart from maybe some program bugging out, but that's not likely.

Honestly, a scaled mode is NOT ACCEPTABLE, though. It will always appear fuzzy. I would live with changing display modes in this case, especially since it's just hitting a button a couple times on the remote.

A question, though: Look at this image:



Do you see a sharp, defined transition between the green and purple, or do you see a more muddly blurred transition like this:



The scale of this image is about maybe 5 or 7 pixels wide. Just curious as I have this problem with my set. I believe the issue doesn't arise in Windows, though. Only Linux.

[odditude]

spend 10 seconds in ms paint making an image which is a checkerboard of single black and white pixels. find a resolution (likely the native of 1920x1080) that shows it perfectly with no smudging, and leave it there.

oh, and none of those resolutions are 1080p except for 1920x1080. your tv simply interprets anything over 720p that's not interlaced as 1080p, as hdtvs are wont to do.

[nintendo_nerd]

See, that's the thing, there are two methods of getting rid of overscan; one is to use the TV's built-in full pixel mode (which doesn't get saved in the TV settings...why I don't know) The other is to use the options nVidia recommends, saving it as a customized "1080p" signal, which is saved in the nVidia control panel. I was looking through the resolutions that are supported when you use the PC/VGA port on the back of the TV, but only saw what modes are supported by HDMI, not actual dimensions.

Supported Resolutions when using PC port (VGA):
Signal Type: Analog RGB
640x480 - 60/75Hz
720x400 - 70Hz
800x600 - 60/75Hz
1024x768 - 60/70/75Hz
1280x768 - 60/75Hz
1280x1024 - 60/75Hz
1360x768 - 60Hz
1920x1080* - 60Hz

(* Quoted from manual "The 1080p timing when applied to HDMI input will be treated as video timing and not PC timing. This affects Picture settings, Wide Mode settings and PIP settings. To view PC content, set Picture Mode to Custom, Wide Mode to Full, and Display Area to Full Pixel") Perhaps that's another way I can save the settings without changing the 1080p resolution. I'm assuming what they're referring to here is what settings to use when you're on an HDMI connection and not VGA.

Supported HDMI Modes:
Signal Type: Digital
480i
480p
720p
1080i
1080p
1080p24

No specific resolutions are listed per se, just the SD/HD modes the HDMI supports. But if I understand you correctly, what the "virtual" resolution is, so long as it's recognized as 1080p, it shouldn't matter with the TV, yes? If nVidia specifically instructs the user (me) to do so, they wouldn't tell you to do something that they know would have adverse consequences. Just to clear things up, I'm currently using the HDTV as a secondary, not as the primary. Oh, and that purple/green image displays clearly in Windows 7.

YOU QUOTED THE DAMN MANUAL WHICH TELLS YOU EXACTLY WHAT TO DO.

maybe you should try following those directions.

(hint: they'll work)

Yeah, I probably should


As if you needed to overemphasize that badly

Well, given you ARE the zboard coward, the overemphasis was needed, in my book.

on another note, can I put in a request for nintendo_nerd's title to be "zboard coward"?

Hey! Now that's a title I can be proud of! But hey, whatever sinks your boat.

Battleship sunk!

Yeah, so much for that if he's gonna react like that... DAMN.

Do I look upset to you? Yeah, that's what I thought.

fixed.

Hahahahahahahahahahahahahahaha. Except everyone knows that he used to be neo_bahamut whatever

on another note, where's that spinning Link thing someone made here?

Sounds good to me.

WAHT UP WIHT BAHUMAT?

[nintendo_nerd]

WAHT UP WIHT BAHUMAT?

I guess what I'm trying to say is, even though the signal is "1080p", would the HDMI input still support it? I see the list of supported PC mode resolutions, but not HDMI input resolutions. The manual just lists them as 480i, 480p, 720p, 1080i etc. No numbers, just modes.

[paulguy]

If it works, it works. Just _try_ it. It'd take less work than it did for you to make that post asking if it'd work.

[Deathlike2]

Stuff isn't going to explode because you tried... unless you're trying to fry eggs with your computer.

[odditude]

480i = 720x480@30Hz (interlaced)
480p = 720x480@60Hz
720p = 1280x720@60Hz
1080i = 1920x1080@30Hz (interlaced)
1080p = 1920x1080@60Hz

and for the love of god, JUST SET IT TO 1920x1080 ALREADY

[nintendo_nerd]

480i = 720x480@30Hz (interlaced)
480p = 720x480@60Hz

1080i = 1920x1080@30Hz (interlaced)
1080p = 1920x1080@60Hz

and for the love of all that's holy, JUST SET IT TO 1920x1080 ALREADY

That's not the issue!! The issue is finding out whether or not the bloody TV supports the altered resolution (nVidia Control Panel-->Resize Desktop) If you actually read the link I posted, it clearly states that one must use the resize option in order to create a "virtual resolution" so there's no overscan on the TV! Instead of being 1920x1080, the resolution would be around 1840x1065 or something to that effect, in order to show up properly. Holy flerking schnit am I getting the run around... I'd rather not use a resolution that ISN'T supported on the TV! If the signal is still being recognized as 1080p, it doesn't matter what the set horizontal and vertical resolutions are, right!?

[kode54]

Your TV doesn't have a "Just Scan" or similar aspect ratio mode? Mine does. It has zero overscan in that mode.

If the Nvidia drivers won't let you output exactly 1920x1080, that's too bad.

Maybe use some display test software to see which resolution is best for your display, if you absolutely can't disable the overscan.

[funkyass]

don't the bravia series have a DVI port?

regardless, there is only one way to answer your question in a reasonable manner, you either do it, or you do not. in other words, bite the bullet.

They have VGA and HDMI ports, but no DVI inputs, unfortunately. That question is whether this custom 1080p mode will have adverse effects or not

[funkyass]

Its not our job to sign off on you trying it.


If you are too scared, then get a vga cable.

[Deathlike2]

If you are too scared,

buack buack buack

It is unlikely the something will explode. If the device is designed correctly, it would not display a picture and/or give you some error message.

So nintendo_nerd, stop being retarded and ffs TRY IT OUT.

This is not overclocking your system... this is just getting the display to work. Dualview has been available for a long time, like Geforce 2 MX aging long. Stop worrying like it's the fucking Y2k bug.
