    I remember running across a thread that talked about a way to force a screen resolution.


    All the displays at my school are Sharp professional class displays... the one I am currently trying to use is a PN-525U. The only connection the school has available (wired through the wall) is HD15 (vga). The native resolution of this display is 1080p....using the built in computer, you can achieve this resolution. However, if you connect any laptop to it, the highest resolution will be 1600x1200.... which isn't even the native aspect ratio.

    Is there any (easy) way to force this resolution in W7?

    Hi,

    perhaps the manual of the monitor helps to narrow down the problem: www.specsserver.com/CACHE/FRPGMBLUPRFI.PDF

    Additionally, the monitor must be properly recognised by your OS, and your external VGA port must support the monitor's native resolution.
    Next would be the dual monitor settings in your VGA driver. If I remember correctly, then the "clone mode" usually works with the same resolution on internal and external display. "Expand Desktop" might be the better option here.

    Also, make sure your display drivers are up-to-date. New drivers bring new EDID information. :)

    My laptop monitor is 1080p., I was hoping clone would finally work properly now that I have a 1080p screen. Nope, bumped e down to 1024x768.

    The problem is that the monitor is not properly recognized. Thing is, I've used at least 10 computers with different configurations that have all had the same issue.

    What I would like to do is simply force the resolution, not worry about EDID and all that.

    Well, if it's not reading the EDID information correctly to begin with, then simply forcing a resolution may break apps and some things may not display correctly. EDID carries more than just the monitor name and resolution modes. It carries signal timing, chrominance/luminance information, refresh rates... and a bunch more information. Try reading about this...
