Dead. Stuck is ON, dead is OFF. Pixels are created from sub-pixels of primary colors, typically red, green, and blue: The reason the dead spot is visible only when blue is displayed is because it is a blue sub-pixel that is dead. When the background is blue, that is the only color on, and it stands out. When the background is another color, the other ...

I recommend a good microfiber with just a little bit of water.

there are two things which are casually referred to as "LED" monitor OLED monitors - these are relatively small, as of the current moment, each pixel is lit by a small OLED, usually used on mobile devices only. there are desktop implementation (read: the sony OLED monitor which cost thousands of dollars). these looks better. they have great contrast ratio, ...

It should have no effect whatsoever. TFTs, unlike CRT monitors, don't use magnetism in their operation.

I think it is impossible to economically fix that screen. Effect you are seeing is caused by breaking conductors inside the screen. Basically, TFT screens have horizontal and vertical conductors inside for each row and column of pixels (second image on the link). Once the connection is cut, pixels from the break point are uncontrollable. If you press the ...

There are two issues. First, the arrangement of subpixels - Microsoft's ClearType is optimized for horizontal arrangement of subpixels. I'm not aware of any LCD panels that are made with vertical subpixels. You might be able to configure ClearType to lessen this problem. Second is the viewing angle of the display. There are different LCD technologies, ...

You can purchase special wipes for monitors. The best i have found are the ones that come in two parts. The first part is like a baby wipe which contains a mild solvent to clean the screen. The second part is a dry towel to remove excess cleaner.

The shorthand format for resolution in screen or camera taking - a number followed by p, or a number followed by i, means p - the "progressive" digital film format or i - the "interlaced" digital film format. The number that goes before i or p simply means one of the two lines of dots that make up the resolution - it is always the vertical or side line ...

Sometimes a quick google is the smarter option.. From everything-science.com Monitors are indeed calibrated differently for different hemispheres. LCD monitors are not affected. Some high-end CRT monitors have an OSD (on screen display) that allows you to select which hemisphere you're in. emphasis added for effect.

I worked for some time as a Lenovo service technician, and I've done more LCD panel replacements than I care to recount. Here's a general play-by-play for a LCD panel replacement: Disassemble the laptop body to the point that you can remove the screen assembly. This is probably as simple as removing the keyboard, but you may also need to remove a seperate ...

Low refresh rates are only problematic on CRTs (where they cause flickering), not on LCDs. Because of this, most LCDs only support a single fixed refresh rates, usually 60 or 75Hz. I don't think you could break one by trying to set it higher; it would simply refuse to work or ignore the setting. With CRTs, there is a potential for damage if you exceed the ...

The first thing to check is that your Windows screen resolution is set to the native resolution of the monitor. In the case of your Samsung SyncMaster 732NW, it has a native resolution of 1440 by 900 pixels. Whenever you make any changes like this, and the screen is still fuzzy, you should check to see if it's just a simple adjustment issue by activating ...

Use a non abrasive cleaning solution, diluting isopropyl alcohol (not rubbing alcohol, as it may contain oil) into a solution of 50% alcohol and 50% with distilled water water (or purified/bottled water). You could also buy a cleaning solution that does not contain bleach, ammonia, or vinegar. Before you start, power-off and unplug your monitor. Spray the ...

On an LCD display, there is probably no difference between the different DPMS modes, which are really specified for CRTs. From Saving Power on idle PCs: … for an LCD display there is often no difference between standby, suspend, and off.

You should really watch this video by Bill Hammack. In it, he explains how backlit LCD monitors work (he is literally like Bill Nye the Science Guy, but for adults - his videos are awesome to be honest). Most modern LCD panels should not "leak" anything, since although liquid crystals are a liquid, they don't necessarily "flow out" of the monitor and leak ...

For a more in-depth explanation: You got the concept wrong when you imagined it to be millions of LEDs flashing the different hues of colors to give you a display - all these kind of monitors are made of invariably 2 layers - a front layer of LCD (Liquid Crystal Display or Liquid Crystal Diode) that makes up the dots you see as pixels, along with the ...

Best thing to do is let it dry for 5-7 days in an air conditioned room. Then see if it still works. No need to open it up.

A "micro fiber" cloth (most LCDs come with one these days) and distilled water.

White LED's are actually blue leds with a yellow phosphor, and thus creating an white impression. This technique allows a colour gamut slightly wider than sRGB, but not very "colourfull". RGB leds consist of 3 individual colour leds, red, green and blue. These allow an enourmous colour gamut that covers most standards like AdobeRGB and NTSC. Panels with RGB ...

It sounds as if you're afraid the vibration from the bass of the speaker will damage something. The answer kind of depends on your speakers. From your description, it sounds as if they're standard small PC speakers, which would probably not be able to induce that much vibration in the monitor. If you have a meter-tall woofer back there, all bets are off, ...

Refurbished means that the item has been returned for whatever reason to the manufacture. This could be simply because the wrong part was ordered and opened, returned and then resold as refurbished. It could also mean that it was shot by an angry dad in retaliation to their daughter's shenanigans and then returned under an extended warranty. However, in both ...

I'm not seeing this effect myself (white/black Paint windows), and you've probably tried this already, but how about the Automatic Display Brightness setting in the Intel HD Graphics Properties (Advanced mode)? Click for full size Especially if it's in a dark room, it sounds like what a smartphone's 'light sensor' would do: when it's darker, turn down the ...

LED: Refresh rate should have a minimal effect on energy efficiency. The LEDs only draw power when they are energized, and the overhead from the control circuitry should be more or less constant. (Note: this refers to 'true' LED displays, not LED-backlit LCD displays, which may or may not actually be commercially available at the time one is reading this.) ...

The most likely explanation is that the blue wire in the video cable disconnected when they pulled the monitor. Make sure that it is securely connected at both ends. If so, then try a different cable because it may have a break inside the cable. I had a similar problem with an old CRT monitor, but mine turned purple-ish because the green wire was bad and ...

Try another cable (and check for loose connection at the monitor's end), and try the monitor on another machine. If it shows the same problems there, the monitor is most likely defective.

Speakers have big magnets in them, and in the old days CRT monitors used to use magnets to control the cathode ray gun in back. Putting good speakers right next to a monitor resulted in problems (the cheap speakers that sometimes mounted directly to the side of a display were just that: cheap, with small magnets). These days, it's just not an issue as LCD ...

The dimension change is due to an industrial "change". In 2008 the computer industry started to use 16:9 as standard aspect ratio for monitors and laptops. According to a report by displaysearch the reasons for this were/are:[5][6] - Innovative product concepts drives a new product cycle and stimulating the growth of the notebook PC and LCD monitor ...
