I'm attempting to create a generic graphics controller for VGA monitors with an Altera FPGA via a VGA connector, but I cannot find any good online resources explaining the standard specification which monitors use. I've found all the pin descriptions and some resources which describe how to create a specific graphics controller, such as ...
Does windows provide any api calls to detect if a monitor is presently connected on the VGA port by using DDC I or DCC 2? I am trying to figure out a way to know if a monitor is connected and turned on. ...
Hi. Is it possible in Java (or any other language?) to detect if there's an available external screen (on VGA or DVI) and start the screen, and send graphics (text and stuff) to it. An example: In Powerpoint, if you have an external screen connected, and you go "live" or start the presentation, it will show on the external screen. I'm ...
About 15 years ago, I used to amuse myself and annoy my CS teacher by writing bad code that would directly modify the text on the monitor. This was/is easily done by accessing video memory at 0xB8000 on VGA-equipped PC-compatibles. Fast forward to today, I decided to try out my old trick through a debug port that gives me access to rea...
I want to write a software, when monitor connect with D-sub connector, this software will pop-up, and ask user to mirror monitor or extend monitor. but i doesn't find any event emit when d-sub connect. on Windows vista, if you connect a monitor, vista can pop-up a software to same thing. does anybody know how to detect d-sub connect ev...
Hi All, I am facing trouble enabling "High Resolution" mode in WM6 Professional. I am using a HTMLView.dll to embed an HTMLControl in our application. By default the "HTML" Shown is not in "High Resolution" Mode - The App is appearing all zoomed up and as how it is displayed in lesser resolution Emulators/devices.(QVGA) I have already ...
I am using compaq presario cq40 laptop with windows seven ultimate(32-bit OS). I would like to access the 15 pin VGA port using Matlab (preferrably using the Data Acquisition Toolbox). Do I require extra drivers or should download anything from Mathworks.com ?? I have already developed a program for sending digital signal through parall...
I have a function to print characters on the screen that is like this: void print(int colour, int y, int x, const char *string) { volatile char *video=(volatile char*)0xB8000 + y*160 + x*2; while(*string != 0) { *video=*string; string++; video++; *video=colour; video++; } } And I want to prin...
I need to put out a VGA signal from an AT91SAM7SE512. How can I do this without using an extra controller? I saw stuff on the web, but it needs to be able to modify the specific pixels. ...
Does anyone know an ARM 9 development board that has Ethernet, USB and a VGA or TV out? ...
Hello, I had compiled some examples from svgalib, the console show : Using EGA driver svglib 1.4.3 Nothing more, its like its drawing somewhere but I cannot see it. This could be a ver very noob question about svgalib, but also a configuration problem. Also I check the virtual console that it says is drawing (if I run from X), runni...
HI there, I'm trying to use UIScreen to drive a separate screen with the VGA dongle on my iPad. Here's what I've got in my root view controller's viewDidLoad: //Code to detect if an external display is connected to the iPad. NSLog(@"Number of screens: %d", [[UIScreen screens]count]); //Now, if there's an external screen, we need to...
Is it possible to mirror the Screen over the VGA Connector? Can't find anything about this. ...
I'm working on an app that is similar to a Presentation application (Keynote/Powerpoint) for the iPad, that will use the VGA adapter to present on screen. However, if the presenter is using the external display for the presentation, I'm wondering if it's possible to have a miniature version of what's on the external display show up on th...
That's all, I want to know if someone unplug the monitor and take several actions, any idea? Thank you ...
I have the need to display a specific view on a separate screen, similar to how Keynotes handles presentation mode. I've managed this successfully by checking how many screens are available, and then adding the view I want displayed as a subview of the second window. However, if I dismiss the parent view that handles the creation of th...
Ok, I think its possible I've misunderstood the correct way to implement an external screen on the iPad and it is causing me a lot of headaches. Since this is a long post, what I'm trying to do is create and send a view to an external screen over VGA, and remove the screen once I'm done with it. I'm having retain count issues so can't ge...
Hi, I tried mirroring the screen of a simple new TabBarApplication with iphoneos-screen-mirroring for iPad: http://code.google.com/p/iphoneos-screen-mirroring/ Everytime (also without including the code) if I try to activate the TV-out in Simulator mode the app crashes without errors. If the external TV-out is activated it staies bla...
Hi guys, I am outputting a UIWebView on an external screen using the VGA connector and am able to display web pages. The problem arises when a video is embedded in the page. What happens is that the video is shown as fullscreen on the external screen, and completely hides the web page. It doesn't seem to be able to play inline... The...
Hi there, i have to customize a debian based distro to run on some pc, showing some advertising on screen (with firefox in fullscreen mode). I'd like to write a software (script or compiled) that checks every X seconds the status of the VGA/HDMI cable and upon disconnection send an email to the administrator. It would be nice to check i...
