I work for a company that makes software to display 3d visualisations. We often grab still images from this software to use in printed media but clients often request the images be print quality and large (300dpi @ A2 or A1 sizes). We have a 30 " cinema display so we can capture images at 2560 x 1600 but I'm wondering if there is any software that would enable me to "fake" a higher resolution (either using the video card scaling or some other method). We use Nvidia Gaming video cards (GeForce 9800 GTX, GTX 280, etc) and our software is directX based.
Cheers
caliban: an A1 poster is rarely required to have a full-size detailed image. If you have a poster, you can go with a somewhat lower resolution most of the time. But normal screen resolutions are ridiculously tiny for printing. – Joey – 2010-06-07T22:33:27.570
Can you set your video card's resolution to higher than your monitors? Obviously you won't be able to see it, but perhaps you could script your machine (in AutoHotkey or something) to increase the resolution and then take a screenshot, and then lower the resolution? – Matthew Lock – 2009-09-09T04:04:56.143
typically can't set it higher than monitors res, at least not through nvidia control panel. Custom resolutions need to be tested before they are accepted and all the larger ones I've tried seem to not be accepted because they're beyond the monitors native resolution – Matthew Walker – 2009-09-09T04:31:39.910
To the answers below. Resizing is an option I guess but technically I'm still losing detail. I remember with some laptops I've hit situations where the desktop was larger than the viewable screen area and the screen slid around when the mouse reached the edge of the scree. Does anyone know what this is called and how you make it happen? This may be one way to fake a higher res in the 3d application – Matthew Walker – 2009-09-09T04:32:14.497
1300dpi @ A1 is equivalent to having a resolution of 14031 x 9921 pixels, which is equivalent to 139 megapixels. I don't think any graphics card can output to that resolution now. – caliban – 2009-09-09T05:07:29.793
