- Q: I changed the resolution of my screen to check out which one best fits my viewing but my LCD tv(what I use as my monitor) doesn't support it. It says Unsupported and now everything is black. I don't know how to turn things back to normal since I can't see a thing. I tried to restart my computer but everything is still black. Is there any shortcut key that I can use or something? I'm on Windows 7. Thanks!
- Restart the computer, hold down F8 as it boots and then choose 'Start in VGA Mode' from the advanced boot options menu. Once it's up and running you can choose a display mode that your monitor supports. After you've got it running right click the desktop and choose 'Screen Resolution' from the context menu. Then click 'Advanced Settings' which is written in blue on the right hand side of the window that just opened. In the box that has now just opened click the 'Monitor' tab and make sure that the checkbox labelled 'Hide modes that this monitor can't display' is ticked. Edit: This is probably because you're using a TV instead of a monitor, a TV might not communicate with the graphics card to tell it which modes it supports. If you look on the TV manufacturer's website they might have a driver for your computer to use it, if so then your computer will know which modes are allowed.
- Q: Is a LED monitor a liquid crystal display?
- LCD is talking about liquid crystals, and there are two kinds of back light. They are cathode ray CCFL and led LED, and the two are LCD liquid crystalThese two methods do not have any good or bad in specification, and the effect of imaging is not bigWhen the liquid crystal came out, it was basically CCFL backlight, so I didn't mention it. It was called LCD directlySince LED came out later, it gave a more advanced impression, and it made the screen thinner, which CCFL could not do
- Q: This morning, when I turned on the computer, the monitor went on and on. It was not the flash of the indicator, but the flash of the screen. And a little flower screen. I checked the connection between the power and the video card. It should be all right. After about 1 minutes or so, it doesn't flash. It seems normal. Also, the screen looks very dark when the monitor flashes. Is it damp? The monitor is the new new computer that has been around for more than 1 months.
- High pressure liquid crystal display panel output is not stable, the screen has been flashing, recommended repair
- Q: LCD display on the dark, and then turn off the display switch, re opened, but also show that it is dark
- Screen light on the dark, that is, short-circuit phenomenon, the machine self-protection, to eliminate short phenomenon to normal use.This kind of failure is usually part of the power problem, if you have your own ability, can open the machine to check the circuit board, the power supply should be part of a capacitor bulge leakage, then the pressure plate is damaged or short tube to burn out, to see if the capacitor bulge, related to the capacitor should be replaced. For ordinary people, only the visual fault self repair, if it is to change the pressure plate or tube for master repair, high-pressure plate lamp cost about 15 yuan, also a few dollars, see how much you accept master wages.In addition to show is the flash of a dark, just before the tube is not bright dark, you can connect the computer into the normal display open system, invisible image also never mind, listen to voice can know already in the system, then find some light flashlight, sticking to the screen look carefully, you will there are in fact found image display, backlight lamp does not light but you can't see it, with a flashlight light can vaguely see the imageIn this way, we can judge the backlight problem and show that the part is normal. The backlight is composed of three parts, the power supply, the high voltage board and the lamp tube.
- Q: I have a 20.1 Sceptre.Scenario:1. Turn on computer2. Turn on monitor3. Monitor stays black but the power light flashes on and off4. Computer boots up normally5. After 20mins-1hour, monitor finally displays desktop and everything works again6. Turn off computer and monitor. Go to sleep.7. Wake up, turn on monitor and computer.8. Repeat steps 1-6. Add 30 mins to step 5 per day. (Up until now it takes a few hours for it to work. Right now it won't even turn on)*I have plugged my monitor into another computer that has no GFX only to get the same result.
- Hi there, Very good description of the problem. It sounds like it is time for a new monitor. A good time to get a 23-24 inch LCD monitoryou will love the new monitor. The monitorat link below for $220- has all three inputs plus a built-in HDTV tuner so you can watch TV on it also (just connect cable box, etc plus your computer) Also has good name and specs. Hope this helps, Al
- Q: 47 and above
- Mostly any LCD you can find will be able to be used as a monitor. It's now a standard norm that they have DVI, HDMI, VGA, etc. inputs on them, enabling them to double as a computer monitor. You probably won't find just a soul monitor that big, they will be equipped with tuners, but will probably cheaper than you could find a pure LCD monitor in that size. Best Buy, Circuit City, Ultimate Electronics, even Wal-Mart and Target's models should be adequate displays. :D Good luck!
- Q: Why does LCD display change color from side to side? Is it different? That kind of good? Colloquial point: will it change well? Still won't change, okay??!!!!!So LCD products will have some visual angle restrictions, and that's the same thing? Is it too far from the limit?I bought this computer long not long, the LCD I see other people also change color, but last time to sell computers, which one of them, a LCD display will not change color? Which one is good?The same is liquid crystal, 22 inches, and then my computer color, I see the computer where there is a computer, do not change colorNow, yes. Do I want to change the one that doesn't change color?
- Ed CCFL1.CRT image tube screen2.LCD LCD screenCRT CRT screen prices cheaper than the LCD LCD display, the focus is clear, the quality is not stable, the screen is larger than the LCD LCD screen thickness, not very convenient, the quality is not too clear, too long to use, the eyes will not be comfortableLCD LCD screen, can adjust in accordance with the visibility of the screen height, clear picture quality, stable, with too long eyes not comfortable, the volume ratio of LCD liquid crystal display screen thinner, more convenient, cheaper than your CRT display, but the value for moneyMore beautiful than the CRT display, showingRight now, LED is the best
- Q: I have a 17 LCD monitor.I played MW2 but I see trails of very fast visuals.When there is fast action on the screen I can see wierd effects,which I believe is called 'The Ghosting Effect'.
- Sounds more like a GPU issue than the monitor.
- Q: i need help! pls tell me how has the computer LCD monitors changed and developed over the past years!!!!! a million thx to u all!
- Yes. The biggest change has been the drop in price. TN technology has been a mainstay of LCD panels, but has become faster to respond and the introduction of prismatic layers has improved the viewing angle. Alternative liquid crystal orientations have improved viewing angles - In-Plane-Switching (IPS) and a variety of vertical alignments and also has better gray scale tracking for luminance and colour. Usually at some level of price, brightness and response time. Improvements in the scaling algorithms has made the display of non-native resolutions better (but still not especially good) Improvements in the DLP processor in the monitor have given better uniformity and better response time (by overdriving the pixel for 1 cycle to get the crystals to move faster) Improvements in the CCFL backlights have made them brighter. Improvements in the colour dyes have produced better colour ranges. The breakout of LCD TVs has also meant that prices have dropped and screen sizes have gotten larger as the manufacturers have set up production lines for bigger and bigger pieces of glass.
- Q: I bought a monitor. What's the way to maintain it?
- Daily maintenance points:1 、 liquid crystal display for a long time do not use, please turn off the power or set the host for power-saving mode.2, as long as possible to reduce the use of bright white screen for a long time, these two points can slow down the aging of the tube, and extend the service life of the monitor.3. Keep the storage and use environment clean and correctly clean the screen surface.4, away from the high temperature and humidity environment.5, no liquid upon screen and machine.6, strictly prohibit extrusion impact screen surface.7, avoid unnecessary vibration.8, do not disassemble and disassemble.
