wireless monitor

Hi all, I'm in for my first topic: i'll get a new pc soon, and I wanted do install a 2nd monitor, not far away from my bed, so it would be easy to watch films. The pc would stand in the same room. Is there an easy way to connect an (old) tv, or a monitor (wireless) to your pc? Thnx Arnout PS, I'm from Belgium, so sorry for my English ;)

My monitor screwed?

I've got a 19 inch flat screen crt monitor hooked up to my mac. And when I play my music really loud, the image almost shakes like it would if I had the stereo hooked up to the power bar with it like it used to be. The stereo is on it's own breaker right now, but is it doing that from the actual vibration of the picture tube or is it dieing on me?

Computer monitor help!

The story is my 6 month old computer monitor is playing up and I need advice on what to do. The ploblem arised about a week ago and has persisted til today.  When I turn the computer monitor on, instead of the usual flash of the Acer logo it repeats 18 times!  This number remains constant and is bloody irritating.  Also when the computer is on it periodically flashes no signal (when there clearly is a signal) for about a minute and then refreshes the monitor and repeats.  Even whilst I am writing this it is there. What should I do? replace the screen or something else? HELP!?

Mounting an LCD Monitor

Hello everyone! I am working on project that involves mounting a 19in LCD monitor onto a board. The monitor has 4 threaded holes in the back for mounting onto an arm or wall mount. I was wondering if anyone knows what kind of screws to use or has any advice on properly and securely mounting the monitor. The monitor is a Westinghouse 19" LCD. The whole project is going to be a small entertainment center for my monitor. I am going to attach speakers and accent lighting. I am doing this for a class project and drafting it in Vectorworks. *If anyone is interested in looking at the plans I will send them to you; however please don't redistribute them. They will be in DWG format. GC

Half broken monitor

I recently bought a 19 inch LCD monitor for 40 bucks (used). It works perfectly for about half an hour (i havn't timed it) and then the screen just goes blank. If i turn it off and then back on it works for a couple of seconds then it turns back off. If I let it be for a while (like an hour or just when I'm not using my computer) it works fine for another half hour. Is this an overheating problem or what is going on?

LCD Monitor Repair

Congrats! Instead of throwing away your broken LCD monitor, you've decided to fix it. What do you have too loose by attempting the repair yourself? It's already heading for the trash can or the e-waste center. By repairing it you will probably save from $100 to $200 or more! If you have done any reading at all on the web, you have already discovered that bad capacitors account for a large percentage of all LCD monitor failures. If your monitor flickers when you start it up, the screen is dim, has strange lines on it, clicks, etc., then this information is just for you! The repair does not require any special knowledge or skill. About the only tools you will need are a putty knife, a screwdriver, a pair of pliers and a Radio Shack soldering iron. Without getting into too much technical jargon, there are two main components inside your monitor, the power board which powers the inverter (lights) and video, and the video board. The power supply circuit board must be removed before you can replace the capacitors. You must open your monitor and examine the capacitors on the power supply board. Each monitor will have a power supply circuit board. Each monitor model will have a slightly different board. They all look about the same. Some have more capacitors, some have less. Most all LCD monitors have a large 400v capacitor. These rarely go bad. There's a video at www.youtube.com/watch that shows you how to disassemble a Viewsonic monitor, and install new capacitors. This is a great video! There's also a good tutorial that shows how to completely disassemble a Samsung 204T LCD Monitor. It's a step by step guide, which also includes a "how to solder" video. Although this tutorial is for a Samsung 204T LCD monitor, the information found here can be applied to almost any monitor. Between the YouTube video on the Viewsonic monitor and the tutorial you should have no problem installing new capacitors in your LCD monitor. Good Luck!

broken monitor help?

I've had this monitor for years and now when i pug it into any computer it is black. i know it is getting something to the monitor because when i plug it into a com. it turns a different shade of black. Plus when i turn the monitor off then back on it show me a quick glimpse of what the screeen should look like if it worked. i presume there is a short in the monitor. i believe it is a cft monitor. b4 i open it up i want to know if there is a simple diagnoses. oh and i did try messing with the brightness and contrast. i wouldn't be suprised if i had to open the monitor. i le it sit for a few days to allow the capacitors to discharge. i am really good with a soldering iron so if i have to replace a resitor or capacitor it'll be fine. and p.s. is there a way make a tesla coil out of simple parts like a day creation? and to all those who have jailbroken ipods and iphones with installer is anyone els experiancing problems downloading Cracked apps? thanks -miiwii3 some one help

Monitor powered by ATX

I searched for hours with varying keywords and can't find too much information...  12v to pin 1 and GND to pin 2 but what do I do about the neutral? I read a xbox 360 laptop mod but it involves the 5v too, and connects it to the power brick. I'm trying to do something different. Trying to make a lunchbox out of a macpro 1.1 case. 1 wire to plug into an outlet is better than needing two. Before I get into this project im trying to understand what I need to buy and feel kinda silly asking such a question which should be extremely simple but I want to be safe and dont want to fry anything. For those that are actually interested in what I'm doing, I kept staring at the case thinking "what can I make with this, and the items I have laying around?" I thought I'd 1-up the basic hackintosh build and go against the grain of using the case how it's intended. I flipped it so the side with the I/O ports were sitting flat, measured the inside which gave me 7" of workable space with 0.4" wiggle room which made perfect for an mini ITX to be laying flat down instead of against the wall. I thought I could take my dremel and cut out an area for a LCD monitor. I have enough DVD drives laying around as well that I could make a "push tray to eject keyboard" sort of slide out keyboard upgrading the rails, using an ultra thin keyboard with a track pad and top it off with sound activated lights and my 1.5 TB HD that's almost full of music. I realize I can do this with a laptop and pocket usb speaker/light effects, but it wouldn't be as cool and I wouldn't get to reuse these items I have sitting around.

Samsung monitor strange behavior?

I have a samsung S27A350H 27" 1080p TN Monitor which for a long time has worked just fine, permanently plugged into the HDMI of my old desktop. However I now have a better laptop which replaced the desktop, but I find that the monitor occasionally will not display a picture when plugged into my computer. I have nvidia display output settings set to output 1920*1080, 60p, with full (not limited) 8 bit colorspace. I do not know the settings of the HDMI output. I find that if I close my laptop lid, W10 goes into either a sleep or hibernate mode, and stops providing a signal to the monitor. If I wake windows again, the monitor will not display anything. Windows appears to detect the monitor fine and extend my desktop as it should when this monitor is detected. However the monitor appears to bounce between looking for a "digital" and "analog" source (HDMI and VGA respectively) Unplugging and replugging the HDMI connector has no effect. Windows detects the monitor fine, monitor does not. Changing the output resolution, frame rate, and colorspace does not appear to change this behavior. The monitor requires a deep power-cycle. Powering it off for several minutes (supposedly to allow charge to bleed away from internal capacitors.) usually (but not always) temporarily fixes the issue. The length of time needing to be unplugged seems to vary between seconds and days. When the monitor enters this nonfunctional state, no HDMI signal is detected. (tested by replacing my computer HDMI source with a raspberry pi. I did not go so far as to adjust the HDMI output settings of the Pi by editing the config file, but the settings were previously changed to optimize the picture quality with this particular monitor in the past anyway. This monitor appears to have a simalar issue with the VGA adaptor. However fixing it is generally a matter of unplugging the VGA and plugging it back in again, or opening up the display settings on W10. Online sources appear to suggest that a firmware bug in the monitor is the culprit, and the only way to fix the monitor is to connect the monitor via VGA and use the samsung firmware tool for this monitor to update / reflash the firmware,the explanation being that a bug in the firmware causes it to overwrite parts of itself, corrupting itself as a result. However the executable provided by Samsung immediately crashes after a successful installation of it and the driver when clicking to reflash the firmware in the software. I found no information regarding the error message that appears. (note my current and only laptop does not have a VGA output. Not sure if this is the reason it crashes, the error message does not give much detail. ---- When I first received this (supposedly broken) monitor from my uncle for free, I found that it was under the warranty period and the problem at the time was that it would not display VGA or HDMI signals. Samsung offered to repair the monitor under it's warranty, and since, it has worked fine, being connected to my main computer permanently.  I suspect the problem then is the same one manifesting now.

convert any CRT TV or monitor into a vector (XY) monitor?

NOTE: I since found a couple links that might shed some light on the question... From HackIt: New uses for old CRT monitors http://hackaday.com/2008/02/25/hackit-new-uses-for-old-crt-monitors/ It would be very hard to do, but it is possible a CRT could be converted to a vector monitor. Perfect for playing Asteroids, perhaps under MAME. You would have to replace all the control circuits, probably with an FPGA and three ADCs (x/y/intensity). Posted at 8:58 am on Feb 25th, 2008 by MoJo Television and PC monitor experiments http://www.educypedia.be/electronics/televisionexperiments.htm old cga/vga monitor to oscilloscope ? http://www.edaboard.com/ftopic57853.html The inquiry: Maybe I am over-simplifying but I was reading one of those examples of hacking into a CRT's horizontal & vertical yoke controls to sync to music:     http://geektechnique.org/projectlab/707/how-to-make-mac-se30-audio-visualizers and had the idea that it should be possible to create a DIY XY monitor (vector display like on an oscilloscope, Vectrex, Asteroids, etc.) for an Arduino or other uC, MAME or Vectrex emulator, from any TV or CRT, once you have hacked into the electron gun's yokes. My understanding being: Raster display: the horizontal yoke (an electromagnet) sweeps the electron gun from left to right turning on the beam wherever there's a "pixel" at that line (which lights up the phosphor at that point making it visible), then it starts over at the next line (vertical yoke moves down) and draws the next line, and so on, Vector display: instead of rendering a moving image frame-by-frame using top to bottom/left to right scanning, shapes are drawn directly to the screen by positioning the horizontal & vertical yokes at the starting point, the beam turns on, and the yokes repoint to the end point, thus "drawing" the line inbetween the 2 points (I would assume this is for straight lines, not sure if circles or arcs are possible?) then the beam turns off, and the yokes get re-positioned to the next line's starting point. I'm not sure what turns the beam on & off or what kind of timing might be involved, obviously that needs to be controlled somehow. Or for color, where instead of a single white (or green, amber, etc) phosphor exists per pixel, there are multiple (red, green, blue) per pixel, and the beam hits each one at varying strengths (or for a varying length of time?) to 'mix" the primaries to the desired color? I'm not sure how that gets handled in a color vector monitor, but I would assume it's something similar to raster? So if we can hack into a CRT's X/Y yokes and move them around with an audio signal, can we control the yokes more deliberately from a microcontroller to plot specific shapes or text, hence a vector display? For those audio/TV hacks, what is the audio signal doing to the yokes that causes them to move? Whatever it is - voltage, resistance, etc - this is what our device would have to control. Possible proof of concept version: make a device to control the yokes' position etch-a-sketch style with a couple of potentiometers, and turn on the beam with a switch or button. If you see a dot of light moving across the screen then it works. I am thinking the controller might need to be "calibrated" for the individual CRT? (Maybe build some kind of calibration mode into the device.) You might dedicate a microcontroller to driving the display - it could receive text or vector shape coordinates via serial, store the shapes to draw in its own memory, and persist or refresh the image independently, freeing up processing power for whatever device it's displaying for. Another idea would be maybe add some kind of way to read light pen's coordinates, thus making the CRT an input device that can be read from the microcontroller or PC (the Vectrex had a light pen right?)  [This would be a cool mod for the Arduino composite TVout as well.] So is this idea possible without a ridiculous amount of work & parts?  I may be dead wrong about how this stuff works (I'm sure that if this was possible, someone would have done it by now?) but figured it can't hurt** to put the idea out there. I have visions of 4-player vector Arduino pong, Asteroids, Tempest, PDP-1 Spacewar!, vector NES Duck Hunt, a vector etch-a-sketch or lightpen drawing or animation program, or vector Atari Video Music. Possibly an open source color vector games system. Or just a vector display system for any Arduino or microcontroller project, made from any TV. **WARNING: maybe it CAN hurt... Evidently hacking into any CRT can be deadly, you have to discharge the CRT and capacitors properly or you can get killed. So please be careful. This definitely is NOT for kids to try at home.

Tips for cleaning a coated monitor?

I have a very large and very nice silicon graphics monitor, but the screen marks very easily. It's coated in something purple that I assume is some sort of anti-reflective coating. Basicly the problems are that pretty much anything that touches will mark it and the marks are occasionally difficult to remove. Cleaning it also leaves smear marks that can only really be removed by rubbing the screen quite hard with a cloth and crap just seem to collect around the edges. I've tried water/soap/petrol/alcohol and pretty much anything else i can get my hands on but nothing seems to work. Any tips?
