For any Widescreen TFT owners, a quick check please

No worries :) I don't think any of those Viewsonic models support pixel mapping, I read it somewhere a couple of weeks ago, if I can find the source, I'll let you know, but I'm about 90% certain that they don't support it.

Tried accessing it in a non-native resolution? Tried a different source (VGA?)?

you can normally only access it when you're runnnig something which would need it. Start up a 4:3 aspect game and the option should then show in OSD ok :)
 
on my LG L203WT i see no options in the OSD
but go in to the nvidia display options there is are 4 settings.
1 display adapter scaling
2 centered output
3 monitor scaling
4 fixed aspect ratio scaling

i set it to number 4 and run games set at 1024x768 there in box in the center of the screen.
is that 1.1 pixel mapping ?
 
that is software supported 1:1 pixel scaling! I'm impressed, i've not seen anyone actually achieve that from software! Can you post some pics please?

ps, sounds like the monitor doesnt support 1:1 pixel mapping, but the software allows it :) Good stuff

This is fantastic. I knew it must be possible.

Does this mean anyone buying cheap widescreen monitors now doesn't have to have their games stretched?

We need more details... most importantly is it specific to that monitor, is it dvi, where in the options is it.

We need to ask some people with the hanns-g and acer if they can get it to work. If someone can confirm this works on the hanns-g i'm going to go and buy a couple. :)

I wonder if i should email nvidia and aski if this work with any monitor?

i'm not sure it will work on all WS monitors tbh, i'm sure people have tried it on the Viewsonic VX2025WM with no luck. Would be interested to know though....
 
If thats the case why some and not others?

I think i'll email nvidia and try and get some clarification on this. If it does only work on some monitors i'll request that they enable it for all ws monitors if they can.

yeah its on the DVI connector and 6800gt card(91.28 drivers)
its in nView display settings/device setting/device adjustments
 
Aspect scaling on widescreen.

I read through the Nvidia help file and found the following points of interest. Its worth noting that the help file covers all possible options in the control panel, and many of then only become available with the right conditions. So only people with a ‘compatable’ monitor can see these settings:

To center or move your on your digital display screen:
1. From the NVIDIA Control Panel Select a Category... page, select Display.
2. Select Change display (flat panel) scaling to open the page.
3. Select either one of these options, depending on which one gives you the result you want:
4. Use NVIDIA scaling
5. Use my display's built-in scaling

Clearly there are two ways to do scaling. You can either let the monitor do it or let the driver do it. It seems that the driver is able to fool the hardware in the monitor by imposing the scaling on the image that’s sent to the monitor, so although the output to the monitor will be 1440x900, there will be black bars imposed down the sides. The monitor will ‘think’ that this is part of the image and won’t scale it.

Change Display Scaling
Use this page to change how lower resolution images are scaled to fit your display.

Use NVIDIA scaling: Your desktop is stretched to fit your entire display screen, even if the aspect ratio is not the same. For example, if your flat panel has a maximum resolution of 1400x1050, an image with a resolution of 1024x768 will be scaled to appear on the screen at a 1400x1050 resolution. Use this setting if you want to make your desktop appear as large as possible yet still fit your screen.

Use NVIDIA scaling with fixed aspect ratio: The desktop is stretched as much as possible to fit your display screen while still maintaining the aspect ratio of the image. For example, if your flat panel has a maximum resolution of 1680 x 1050, an image with a resolution of 1024 x 768 will be scaled to appear on the screen at a 1400 x 1050 resolution with black borders. You may want to use this setting if your desktop looks distorted.

Use my display’s built-in scaling: Your display scales the unscaled image that your NVIDIA GPU-based graphics card generates. Use this setting if you prefer the visual quality of your display's built-in scaling.

Do not scale: Prevents your flat panel display from scaling. This display image remains its original size and centered on your screen resulting in a small though crisp image. A black border may appear around the display image. You may want to use this setting if your desktop appears blurry when you use any of the other scaling settings.

So there you are. Its possible to do aspect scaling/1.1 pixel mapping with software.
The question is, why does it only allow you to do it on certain monitors (not necessarily with hardware 1.1 pixel mapping)?

I ‘m just wondering, perhaps in the same way the coolbits hack works, there is a registry hack to enable this on any widescreen monitor. The coolbits hack worked by setting some registry key to true to enable overclocking, certain graphics cards allowed it by default, some didn’t, and with coolbits all worked with overclocking. It was at the discretion of the manufacturer if they wanted to enable it by default or not, many didn’t because it caused higher rma rates from fried cards and such.

I think this Nvidia scaling thing might to be the same, certain monitor manufacturers enable it, most don’t. So what we need is for someone who has it to compare registry screenshots with someone without it and spot the odd one out… ;)

The only question I’m asking myself is why don’t all monitor manufacturers enable it? Is it because they don’t know it exists I wonder? I just can’t think of any other logical reason not to have this enabled on all widescreen monitors.

We need people with widescreen monitors to have a poke around, and see if they have the Nvidia aspect scaling option enabled or not, and see how the relevant part of their registry differs from others…


Edit: To navigate to the area of the registry where coolbits goes, go to run, type regedit and go to the following location:
HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NVTweak

There are a number of keys in there such as NvCplThermalSettings which presumably enables the temperature monitoring. See if theres anything in there that sounds like it might enable nvidia aspect scaling.
It could be called NvCplEnableAspectScaling or something.

couldnt see anything in "HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NVTweak"
but there is a setting in HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\NvCplApi/defaults, called flatpanel scaling(its set to 0)
 
One thing to note about the Dell 2007W. Although it has 1:1 pixel mapping, I have to say that based on initial testing, the way that it's implemented seems to be very clunky.

For example, if I have my desktop set to 1680x1050, the OSD automatically sets to "stretch" - you cannot force 1:1 from the OSD menu as the option is greyed out. So if I want to play a computer game at 1280x1024 (eg. C&C Generals Zero Hour - which doesnt work properly in widescreen), I have to change my resolution in desktop to 1280x1024, then go to the Dell OSD, change to 1:1, then load up the game. Then after I've finished the game, I have to go to desktop and re(set) the resolution to 1650x1050. Once I do that, the Dell OSD automatically - even without user intervention - changes the setting to "stretch". If I want to play the game again, I have to go through the whole process again. :rolleyes:

Why can't the OSD simply "hold" the selected 1:1 pixel mapping option and allow me to change the desktop resolution as as when required?

It just seems a VERY long winded and unncessarily tedious way of doing things.

EDIT: I have found a solution. Basically the solution is to bypass the monitor's OSD scaling altogether and use centred image in Nvidia control panel. It works perfectly and is FAR SUPERIOR to the monitor's built in, cumbersome and isdiosyncratic OSD scaling options. Easy way of having your desktop set to 1680x1050, each game set to the resolution of your choice with the flexibility of being able to alt-tab in or out of each application whilst maintaing the correct aspect ratio for each.

Baddass - as a suggestion, you may want to ask people to provide info as to whether the Nvidia control panel or ATI equivalent overcomes any particular monitor's lack of built scaling. Obviously, if it does, the lack of built in scaling isn't an issue. Would just be another column in your table and make it more comprehensive ;)
