Hi.
I have a HMI program made with WinCC Flexible, and it shall be displayed at an exhibition on a 43" widescreen monitor. I think it is a HDTV screen actually, but I havent been informed about the exact details. I do now that the screen has 16:9 aspect ratio though, and that is the problem. All the screen resolutions that can be selected in WinCC Flexible have 4:3 aspect ratio. 1600x1200 is the max resolution that can seleceted. Also from the PC there is only a DSUB-15 port (VGA) available, no DVI or HDMI.
Here are the questions:
1. How does one get a screen resolution in Windows of for example 1366x768 ?
The available selections that I have now are the typical 1024x768 .. 1280x1024 .. 1600x1200.
The typical HDTV resolutions of 1366x768 and 1680x1050 are not available.
Do I have to install a special driver ?
Or do I have to install a new graphics card ?
2. Is there a limit to what resolution can be achieved with a standard VGA output ?
I have heard something about DVI being required for the higher resolutions.
3. How do the typical HDTV screen react to that a signal with a resolution of say 1280x1024 being supplied to it ?
Does it interpolate the signal to its native resolution ?
Or does it "crop" the picture ?
Thanks.
