CRT Resolution Trouble
in [Hardware]
|
From: George on 11 Dec 2009 19:15 I have a friend who has a problem that seems to stem from a mismatch between what his monitor wants and what his computer can provide. The monitor wants 1680 x 1050, but the closest choices provided by his AGP graphics card are 1600 x 1000 or 1920 x 1080. He sets it for the lower number, but the computer changes that to 1920 x 1080. The too-high resolution causes the image to jiggle. He then has to go to Control Panel and set the resolution back a notch to 1600 x 1000. Beyond another graphics card, how else can he rid himself of this annoyance?

CRT monitors do not "want" a particular resolution (as do LCD monitors that have a native resolution at which they best display an image and every other resolution results in interpolation that causes fuzziness or fringe coloring). More likely you meant that the CRT has a *maximum* resolution of 1680x1050. We are to guess of which OS your "friend" uses? You mentioned Control Panel so would that be some version of Windows? Assuming this navigation works under the unidentified version and edition of Windows, in Control Panel, open the Display applet. Under the Settings tab, click the Advanced button. Under the Monitor tab, is the actual monitor listed there or some wrong or generic version of monitor? You want the correct monitor listed there because then the option "Hide modes that this monitor cannot display" becomes valid. The monitor's definition (.inf file) specifies what screen resolutions and frequencies it can support. Those not supported should not be selected. Go to the monitor manufacturer's web site and get their config file for that monitor (which hasn't been identified here). Follow their instructions for installing their info file. Then select that monitor (if not already) in the Monitor tab, enable the Hide option, and pick a resolution that the monitor can actually support.

But just try and find it :-) If you can't figure out how to do it, for an ATI or Nvidia graphics card, there is always Powerstrip (software with trial period). http://www.entechtaiwan.com/util/ps.shtm http://forums.entechtaiwan.com/index.php?board=7.20 "Custom resolution primer" http://forums.entechtaiwan.com/index.php?topic=24.0 The silicon has been fully programmable, for a couple of decades. It is just the crappy drivers and GUI control panels, that prevent users from getting what they need. I built a frame buffer around 1985 using a single controller chip for the display functions, and even back then, the X, Y, front porch, back porch, and so on, were fully programmable, down to the nearest 8 bits (one character wide). I could have virtually any resolution I wanted, to the limits of the RAMDAC bandwidth. And that was a long time ago. The video card companies just want you to suffer a bit. Paul

A newer driver may provide the needed setting or allow a custom setting for this resolution. Seek one from the video chipset manufacturer, as they tend to be newer versions than the video card manufacturer will have, particularly for aged designs using AGP. However, it seems likely you have an LCD not CRT monitor since it has a resolution of 1680x1050. At that resolution and above, you may find improved image quality by using a video card with DVI output (assuming the monitor supports this as an input), or at least a higher than average quality and short cable if you must stick with analog. |
