hfred Posted March 10, 2004 Share Posted March 10, 2004 My display properties in my mac says I can only go up to 1024x768 resolution is there any way to "hack" my Mac to make the resolution bigger? Link to comment Share on other sites More sharing options...
Elliott Posted March 10, 2004 Share Posted March 10, 2004 What Mac are you using, and with what monitor if it's not built in? Link to comment Share on other sites More sharing options...

Elliott Posted March 10, 2004 Share Posted March 10, 2004 Don't strain that LCD to go beyond 1024x768. It's not good for LCDs. CRTs are fine, but fitting more pixels into one pixel and making it display different colors in that same pixel is a bad idea. It'll be blurry and it's bad for the screen. Besides, I think Apple kinda put that setting in the firmware. I'm sure there's some hack, but it's not wise to do it. Link to comment Share on other sites More sharing options...
Bling3k12 Posted March 11, 2004 Share Posted March 11, 2004 LCD's are set to a predefined resolution. You can't push something like 1280x1024 outta a LCD designed for 1024x768. You can however go lower, and it will stretch to fit the screen. Even if you could set it higher to 1280x1024 or so, you would still only have 1024x768 visible area and would have to "scroll" around to see everything.

the evn show Posted March 11, 2004 Share Posted March 11, 2004 LCD's are set to a predefined resolution. You can't push something like 1280x1024 outta a LCD designed for 1024x768. You can however go lower, and it will stretch to fit the screen. That's not exactly true. Your LCD uses a 'descaler' to process the incoming video signal and make it fit on the physical pixels in the lcd display. Typically this is used to scale lower-resolutions up to fill the display (ie: using your ibook at 800x600) but it can also be used to scale larger resolutions down the same way. I've tried this using an NEC 15" LCD I used to own and it would display 1280x1024, 1600x1200, and 1920x1600 without complaining even though the native resolution was only 1024x768. It's not "hard" on the hardware because the signal is processed by something that's _supposed_ to do exactly that (fix signals to display on the screen). It's not like trying something similar with a CRT where there are moving parts and such. The problems with displaying higher-than-native resolution on an LCD are the same as using lower than standard: it looks AWFUL! I'm sure you could probably trick linux+x11 to display at whatever resolution you wanted, but OS X (i'm almost 100% sure) isn't going to be fooled into that. Like the others have said: even if you could make this work: why would you want to. open an image in photoshop, make it 1280x1024 - then resize it using anything but the nearest-neighbor algorithm then add a .5 pixel Gaussian blur to have an idea of what it would look like. When you only have 1024x768 pixels it's really quit pointless to try to go higher because your hardware physically can't do it accurately. It's like trying to play a 5.1 channel movie back through a single speaker: there just isn't a point. Link to comment Share on other sites More sharing options...
Southern Patriot Posted March 11, 2004 Share Posted March 11, 2004 Good info there Evn Show, but one small nitpick. There are no moving parts in a CRT. Link to comment Share on other sites More sharing options...
the evn show Posted March 11, 2004 Share Posted March 11, 2004 fair enough: I wasn't sure how to describe the relationship between an electron gun in a CRT and an LCD. It's an "analog" process - but not mechanical. Link to comment Share on other sites More sharing options...
Bling3k12 Posted March 11, 2004 Share Posted March 11, 2004 Well, I learned something new... I've never ever seen one that will scale down 1280x1024 to 1024x768, just display the resolution, but only 1024x768 pixels at a time (like on my Dell Inspiron)... I figured maybe you could squish it (as per your Photoshop example) but I knew it wouldn't be remotely useful at all. Link to comment Share on other sites More sharing options...
the evn show Posted March 11, 2004 Share Posted March 11, 2004 If you have a Windows machine + LCD try this: Go to the display control panel. Settings - advanced - monitor. uncheck "hide modes this monitor cannot display" click okay a bunch of times to get back to the display settings panel select a higher resolution. I'm not sure if all LCDs do, but all the 'stand alone' ones I've ever tried worked just fine. Link to comment Share on other sites More sharing options...
sebaz Posted March 11, 2004 Share Posted March 11, 2004 Why would u want to run a 12 in. screen at anything higher? Hook ur laptop to an external display, bigger resolutions and ur eyes will thank you. Link to comment Share on other sites More sharing options...

It's an "analog" process - but not mechanical. Yep, the electrons are actually "moved" by an electromagnetic field (if you've ever looked at the guts of a CRT monitor, that's what the big coil wrapped around the back end of the tube is for).
