Window Managers for High Resolution Displays?

cfish asks: "Recently, I was told by a manager at a major monitor maker that CRTs are phasing out. I have a very weak eye and I read text at 1024x768 on a 21" monitor, sitting 2 feet away. Each alphabet is about 1/4" tall. What makes me panic is the fact that LCDs have fixed resolution and they are simply too small for me to read icons and widget text, like Microsoft's. This is a great chance for Linux to get a head start in a certain market: older folks and those who have eye strain problems. Generally speaking, not many people can read Microsoft's widget text on a 150dpi display, which may explain why no one buys them even that they are available. Imagine how frustrating it could be for medical display (x-rays), cad, image editing to have a high resolution realistic image but cannot read the menu and text. If someone can come up with a Window manager to beat MS on 200dpi displays, no doubt this will capture a strong following in image related applications. I have read about these debates 5 years ago. What has been done about it?"

    Ya know, LCDs don't *have* to be run at their native resolution all the time. You are free to set an LCD to run at 640x480, 800x600, or whatever you like. The nice thing about a 200dpi LCD display is that you can run it lower than the native resolution and still get a great looking picture. Another thing...Windows can be set to a higher "dpi" than its traditional 96. This will increase the font size for EVERYTHING. Just go to Display Properties > Settings > Advanced, and select the "DPI" from the General tab that you wish to use. Beware, as some applications may not look right because they weren't designed to use that resolution. FP!

      Yes, LCDs don't have to run at their native resolution. But they really look like crap at lower resolutions. Particuarlly for displaying text. Which would make things worse for the guy asking the question.

      Run the monitor at its native resolution, tell Windows to use Extra Large fonts, and make sure to set the anti-aliasing to ClearType. ClearType actually makes a very big difference on how legible the text is. I think that's the best bet on getting a legible display on Windows with an LCD.

      If the target image pixel size does not map to the screen pixel size in a clean fraction (1/2, 1/3, 1/4, etc), then some pixels "consume" more of the image than others, making for lumpy-looking text. Averaging could be used, but that would make the edges of the text fuzzier.

      CRT's are still the king of multi-resolutions.

      Using "Large Fonts" settings is probably a better option to try than non-native LCD resolution.

      Actually, the submitter was talking about 200 dpi displays. These (as yet largely mythical) displays would be able to scale down nicely. A 3840x2400 display, for example, can scale down to 1920x1200 at 4:1, or 1280x800 at 9:1, or even 960x600 at 16:1.

      A 1280x1024 display, though, can only scale down evenly to 640x512... which isn't especially helpful unless you're legally blind. This fellow isn't.

      In Windows, the OS is precisely compliant to what the application developer wanted the program to do. For instance, if I write a web page with an "img src" tag with the height and width set in pixels, then the image will be that size, regardless of the resolution of the monitor. If I set the height and width in a proportional unit like points, or to be a percentage of the window size, then it will scale along with everything else. Programming using Windows Forms works the same way, although I know some of the old widgets refused scaling (I seem to recall some difference in the Picture vs Bitmap control in VB 5 or 6).

      In other words, it's up to the app developer to base their UI on the dynamic System Properties rather than on fixed values. If, for instance, Windows YP was developed to "override" fixed pixel sizes and try to make them proportional, it would probably screw up more than it would fix.

  2. Change the font size! by danrees · · Score: 4, Informative

    I might be missing the point completely here, but surely for accessibility purposes (i.e. if you have crap vision), the resolution doesn't matter. All you have to do is change the default font size in your window manager... it's hardly revolutionary :S

    ..and people are working on it. Seek KDE and I found this project on Sourceforge. I assume that you already turn on "large fonts" in Windows. Windows can theoretcally support font sizes that are larger, but the problem is that most applications aren't designed with varying font sizes in mind. Some applications already look messed up with the dpi setting that "large fonts" uses. It's a matter of poor UI design. People use fixed-size images in their programs and expect them to line up.

  5. x-ray by Davak · · Score: 4, Informative

    Here at the hospital we use a high-resolution radiograph system. The text IN the system itself is fine; however, the OS text from win2k is extremely small.

    Luckily, all of these systems only have the imaging system and the OS installed... so the only program that ever runs is the radiograph system.

    Isn't this just a setting, however? I figured the admins were just idiots and didn't bump up the text size.

    One of the things that ships with Windows is the magnifier accessibility applet - for people with poor vision. it turns the top of the screen into a magnified area of the screen under the mouse, so you can have the screen estate nicely laid out, and be still able to read any part of it you want to. (BTW I'm using XP, but I think its available on the other OS versions)

    You can change its settings, make it follow text editing cursor, and keyboard focus, (its quite cool actually, I may bump my resolution down to 1600x1200 on my 17" monitor and use it :-)

    Not only that, when you first start it up, you get a dialog box offering to take you to see more poor-vision tools on the web.

    10/10 for Microsoft on the accesibility features? na, this is /. after all.

    Using XP, but it's almost the same on 2000 and NT:
    1. Right-click on the desktop
    2. Select "Properties" from the menu that will appear
    3. Select the "Appearance" tab from the window that will appear
    4. Select "Large" or "Extra large" from the "Font Size" menu on that pane.

    And you're done. This functionality has been in Windows for, I don't know, a decade or more. Generally, commercial OSs, whether Windows or Solaris or MacOS, leave free ones standing when it comes to accessibility. The reason is that they want to sell to corporates, and corporates have to comply with legislation like ADA. Free software authors generally don't have that incentive.

  9. "LCDs have fixed resolution:" (semi-)myth. by Slartibartfast · · Score: 5, Informative

    What they have is a fixed number of pixels. The entirely unsatisfactory solution to this dilemma is to merely drive it at an inferior resolution. It'll look like garbage, but it'll be bigger. A much better solution, however, is to drive it at an even divisor of the number of pixels, which will give you clean output. For example, a 1600x1200 LCD could be driven at 800x600; the letters will be nice and crisp, and will be four times larger.
