I have an iMac, and I want to be able to turn off the monitor when I go to sleep,. Alas, the iMac has no switch for this. I do not want to put the iMac into sleep mode, i want to write a "expose" like application or service, which when the mouse is put into the upper left hand corner of my screen, the display will sleep. Likewise, if ...
I still use a 19" CRT monitor for my development (both at home and work), but now I'm looking for a wide-screen LCD monitor as my next purchase. As much as I look into it, I can't really find one that pleases me. The problem is that the LCD grid (the black lines in-between individual pixels) confuses me. CRT monitor don't have that prob...
This is an interesting conundrum. We have a WPF app that has a Vista-like theme using soft pastels, Aero control templates, etc. What we've noticed is that this UI appears incredibly washed out on low quality LCDs. Is there a way to boost color saturation application-wide or are we at the mercy of bad monitors? Can we even tell, program...
We have a character LCD (www.cloverlcd.com/pdf/S6A0069.pdf) that we got to work in 8 bit mode. However, now we are trying to get it to work in 4 bit mode but it doesn't seem to be displaying anything. I think the function set instruction isn't been written. Can somebody please check if I am approaching this the right way? I'll post my...
As a web designer/developer/photographer... I was wondering, what is the best free all-round software based tool (on XP) for calibrating your monitor's color, brightness/contrast to the optimal settings so that your work looks as consistent as possible across OS's and monitor types? I know of Adobe Gamma, but is there a better alternativ...
LCDs have 4 data lines. But the data to be displayed in the LCD is given in the ASCII form which is 7 bits. How is that possible? ...
The idea being that, once the brightness passes a certain level, one could switch to a different visual scheme to give greater visibility. Also, if it could be some sort of listener type thing, that would be even better, but I'll take what I can get. ...
I am trying to add info to a VBscript that will determine if the monitor(s) connected to the current machine is an LCD or CRT. I know I can get the EDID info from HKLM\System\CCS\Enum\DISPLAY but I can't use that to determine the monitor type. And the only consistent info I can grab from the WMI classes Win32_DesktopMonitor, Win32_Disp...
Hi, I'm trying to write to an LCD Display using System.IO.Ports in C#, with the SerialPort class. Firstly, it works! My program does write to it successfully and it displays fine... but only after I've run a prior commerical program (LCDC). If I run by program before running LCDC (a full LCD-display GUI program) - the LCD display sits...
Hello everyone, currently I am trying to write to an 20x4 LCD Dot-Matrix Module using Perle's TruePort Redirector. I have the GMS-DS LCD Module connected to a Perle Serial to Ethernet Device Server. As of now, I think that I need to write to a local TruePort interface, which then converts the data and sends it to the Device Server via T...

I'm looking to purchase a Vacuum fluorescent display (VFD) for personal use and I'm looking for anyone who has had experiences with programming to a similar device in linux. My question is not specific to a VFD, it can include LCD or similar, but linux is my target platform. I have a good programming background in C and I'm looking to g...
I have seen applications capable of sending information to Logitech LCD panels and played with that a bit a few years ago. Currently, I have four small LCD panels. Two are CrystalFontz 633s, one came from a 1U EMC data storage box and one was taken from an old ethernet-based KVM, so I've no idea what it's capabilities are. Using eithe...
My colleagues and I have got an interesting little prototype hardware/software project that would follow these loose requirements/specs/implementation details: Hardware: Take simple user input from a couple of buttons, maybe a dial Give some textual output to the user, a 3-line LED would suffice but fancier is OK Powerful x86 CPU requ...

I have an embedded project that I am working on, and I am currently coding the character LCD driver. At the moment, the LCD driver only supports "dumb" writing. For example, let's say line 1 has some text on it, and I make a call to the function that writes to the line. The function will simply seek to the beginning of the line and wri...
I'd like to develop a PC LCD display emulator for educational purposes. The display uses HD44780. I don't know where to start. ...
Is it possible to use any LCD with arduino or I need to stick to some for which the libraries are available. I'm just starting out with arduino and know nothing about interfacing LCDs with arduino. I'm planing to buy Old IPhone LCD as they are cheap and big enough to do something useful with them. Also to use iPhone LCD do I need to add ...
