1:1 Pixel Mapping issue

All,

I am trying to understand this issue. To be honest, the game looks fine in all resolutions so I am having a hard time what the complaint really is. This is my testing results:

Oblivion
2407WFP A03
DVI

Widemode options greyed out, Fill only
1920x1200
1920x1080
1600x1200
1440x900
1360x1024
1360x768
1280x960
1280x800
1280x768
1280x720
1024x480

Widemode options available
1680x1050
1280x1024
1152x864
1024x768
800x600
=====

Xbox 360
Component cable set to HDTV
1080i widescreen Widemode options available
720p widescreen Widemode options available
480p widescreen Widemode options available

Component cable set to TV
480i Normal Screen Format Widemode options available
480i Widescreen Screen Format Widemode options available

    The complaint?


    The 1:1 pixel mapping should work on all resolutions.


    People expect it to work on all resolutions when they buy this unless stated otherwise.


    This monitor is 1920x1200 native. The HD standard is 1920x1080. Things look slightly stretched on Fill mode. The worst case is at 1600x1200. A 5:4 picture scaled to 16:10 is useless.

    ChrisM, you may want to test displaying Windows desktop at different resolutions in order to properly identify the 1:1 pixel mapping issue. It's sometimes hard to make out if a game output is actually stretched. Now, if you're unable to choose a display setting (other than "Fill" screen) at various resolutions you specified in your post then obviously that's a technical issue with the monitor. Honestly, I do not see why it's so hard for Dell personnel to identify the 1:1 pixel mapping issue. I've given up trying to explain the issue to Dell after a total of 8+ hours of talk time on the phone. Anyhow, please let me know if I can be of any help to you as far as testing the monitor is concerned. I can also carry out some PS3-related testing if you want.

    So are Dell not required to replace the monitors with this issue? Ive read a few reports of Tech Support saying no to people regarding this issue.

    Hi,

    Is it possible to have the a computer (laptop) connected via the VGA interface show up with "real" screen proportions (4:3) - I'm looking at 1600x1200, 1280x1024 or 1024x768 - black bars at sides are ok.

    Others have problem with 1600x1200 in 4:3 format (no fill).

    Martin

    Most of you should know that the sales reps and even the technical support personnel don't have technical backgrounds (they know how to read well though).  MANY of them have English/Communications degrees and know much less about the device you know front and back.  I have nothing against those degrees, but people graduating with engineering degrees (and don't compare fast tracked degrees in Pakistan/India to USA 4 year engineering degrees) aren't answering phone/email technical support questions making just above minimum wage.  Ask the next technical support person you call if they even know what pixel mapping is...90% of the time you'll have to explain it to them.

    I think taking the one example that I've seen the most posts / complaints about might help. That example is when trying to use an XBox360, running at 1080p resolution, with the Dell 2407WFP A03 or prior revision monitors.

    - Plug the XBox360 into the Dell 2407WFP using component or VGA.
    - Insure the XBox360 has the latest firmware / software from Microsoft that includes the ability to set the resolution to 1080p.
    - Set the resolution of the XBox360 to 1080p.
    - Play a game on the XBox360 that supports 1080p.
    - Observe that on the Dell 2407WFP, if you do nothing, that the screen is filled.
    - Doublecheck that the resolution being fed from the XBox360 to the 2407WFP is 1920x1080 by going to the Display Settings menu page on the 2407WFP, and selecting Display Info. It should tell you that the signal being fed into it is 1920x1080.
    - Observe also on the Display Settings menu page on the 2407WFP that there are three choices listed under Wide Mode.
    - Try to select a setting other than Fill from the Wide Mode section. You will discover that it is not possible to change from Fill.
    - Confirm once more that the screen is completely filled with graphics from the game. In other words, there are no black bars at the top or the bottom of the screen.

    That is the crux of the problem Chris. Because the Wide Mode cannot be changed when the monitor is fed a 1920x1080 signal (among other signals), the aspect ratio of the source cannot be maintained, thus the image is stretched on the screen. This violates the spirit of what was intended to be displayed, because if the game producer had intended for the game to be shown at an aspect ratio similar to 1920x1200, they would have chosen a smaller resolution which would fit within the 1080p specification. They did not. Therefore, the Dell 2407WFP is defective because it does not properly display the signal fed to it by allowing 1:1 Wide Mode to be chosen when fed a signal other than 1920x1200 via component or VGA.

    Please feel free to correct any mistakes I made in outlining the issue, as I've never actually been able to try this myself... this is just my summary of the information that's publicly available on MANY message boards on the web.

    I think people should not focus on 1:1 mapping. It should be on bad component input looks. It looks really blurry. Great monitor though. Much larger than I was expecting.

    All,

    I will bring my Xbox 360 into the lab next week to test with the Product Group guys.

    Johnny NG,

    Does this occur using component?

    Chris, I hope to get some pics up tonight for an exchange, but i also have a problem that no one else seems to have.  when i set my 360 to the highest resolution possible (1080p equivalent through VGA) I get something im going to call "shadowing".  When an image is on the screen, its "shadowed" on the opposite side of the screen.  Its a white image, displayed horizontally, and appears every couple of lines.  I'll include pics of this, as well as not being able to select 1:1 while in the same resolution.  If im not mistaken, the monitor will not do 1080p over component either... which it should be able to do since the 360 supports 1080p over component, correct?
