I just plugged my NEW LCD screen in and the screen is BLACK?
Your display settings exceed the capabilities of the LCD monitor. You must reduce the settings. Reconnect the original monitor into the video card and reboot to Windows. Reduce the refresh rate to 60hz and reduce the resolution to 640x480 pixels. Reconnect the LCD monitor back into the video card and boot the computer. You should have a picture at this time. Make your adjustments once in Windows. Refer to your user's manual for resolution settings. (Note: be sure to turn off the computer each time the monitors are disconnected from and reconnected to the computer; make sure to secure the video cable connection using the thumb screws to secure the connectors to the video card and the back of the monitor.)
I am getting an OUT OF RANGE or NO SIGNAL INPUT message on my display. What do I do to fix it?
Your display settings exceed the capabilities of the LCD monitor. You must reduce the settings. Reconnect the original monitor into the video card and reboot to Windows. Reduce the refresh rate to 60hz and reduce the resolution to 640x480 pixels. Shut down the computer properly. Reconnect the LCD monitor back into the video card and boot the computer. You should have a picture at this time. Make your adjustments once in Windows. Refer to your user's manual for resolution settings. (Note: be sure to turn off the computer each time the monitors are disconnected from and reconnected to the computer; make sure to secure the video cable connection using the thumb screws to secure the connectors to the video card and the back of the monitor.)
Why does my picture look choppy or washed out on my LCD monitor?
Increase your resolution to match the natural resolution of the LCD screen. This will provide a clearer picture. (See your user's manual for recommended setting for your model.)

Why is my picture ugly, it is not as sharp as my CRT monitor what is wrong?
You are comparing apples and oranges. The technology is different, you lose a little picture quality with LCDs. CRTs at this time are the clearest picture of the two. Increase the resolution one step at a time until the user likes the picture. (The natural state is usually clearest.)
My new LCD has double images what can I do to fix it?
Using a signal splitter, a video cable longer than what originally was provided by the manufacturer or a video cable extension will cause this type of problem. Remove those items and use the original video cable. (Note: always use the signal cable that is supplied with the LCD monitor or display issues will arise.)
I have Windows XP, ME or 2000 where can I get the driver for it?
Use the default plug and play the Windows operating system installs. Not all CTX models will have specific drivers for these operating systems. Check the CTX driver list for your model at www.ctxtec.com.

There are horizontal lines moving down my screen, what is wrong?
Use the PHASE adjustment in the OSD. This should clear up the picture.
I am not getting any power to my LCD monitor. What do I to do?

Disconnect and connect the cables for the AC adapter or power cord. Make sure they are connected securely. Test by plugging the power cord directly into the wall power outlet.
What is the CTX policy on non-performing dots on an LCD screen?

CTX Technology Corporation is committed to providing customer satisfaction by providing quality products. Generally, CTX products have very few bad or missing (non-performing) dots.

CTX has set forth the following criteria for non-performing dots for all CTX LCD Panels. This policy exceeds the industry standard.

CTX Technology's specifications allow for non-performing dots. But, if there is a group or cluster of some non-performing dots less than the allowable number, CTX will consider this depending on colors that are missing and the distance between the quantity of non-performing dots. Also CTX will consider the location of the non-performing dots within a specific area. Non-performing dot can take the form of either a light dot or and dark dot. A dark dot will not have any color at all it will be black. A light dot will have some color depending on the color of the background.

CTX has set a limit to the number of dot anomalies. CTX has adopted this policy for non-performing dots to supplement the CTX limited warranty.

It is possible that any service replacement display may also have some non-performing dots. This should be considered when requesting a warranty replacement or exchange.

CTX allows for 5 non-performing dots for 15"-17" LCDs.
CTX allows for 7 non-performing dots for 19" or above.

General Faqs

I am using Windows 95/98. How can I change my display settings..?
Click Start, then move the mouse cursor to Settings, then click Control Panel, then double-click Display, then click the Settings tab. Adjusting the slider bar generally tells you what you need to know about your video system's capabilities right away.
My video card can only allow me to display at a certain resolution, which I want to exceed...
Not necessarily. Many video cards have room for more memory chips. Sometimes adding RAM to your video card can increase the video card's display capabilities. Consult the video card user manual for the specific memory type you need, and call the card vendor or manufacturer to purchase the additional RAM. You may also opt to purchase a whole new video card altogether, which will allow your desired resolution and provide faster performance.
My monitor will only allow me to display at a certain resolution, which I want to exceed...
Monitors are not upgraded to allow higher resolutions/refresh rates. It's better to get a new monitor entirely if you really need to run at a resolution that exceeds your monitor's ability to run it.

What is meant by "refresh rate"..?
"Refresh rate" refers to the number of times a screen redraws itself in a given time period.
I keep hearing terms like "video card", "display card," "display adapter", "video adapter", "graphics adapter", and "graphics card". What's the difference ...
Nothing. All these terms signify the same basic thing.
What is meant by "video bandwidth"..?
"Video bandwidth" refers generally to the highest input frequency the monitor is constructed to handle. The greater the video bandwidth, the greater (higher, faster) the horizontal and vertical scanning capabilities.

What is the difference between aperture grille pitch and dot pitch ...
Cathode ray tubes (CRTs) such as the Sony Trinitron and Mitsubishi Diamondtron use a type of light filtering which relies on a series of overlaying slotted aperture grilles, rather than grilles with holes in them. Currently, what is useful about knowing whether a monitor has a .25mm vs. a .28 mm dot pitch is that the .25 mm dot pitch generally indicates a higher quality tube with sharper dot (pixel) resolution.
What is a pixel ...
A "pixel" is a tiny colored dot on your display. The word "pixel" is combination of the words "picture" and "element" and refers to the individual dots that, when grouped, comprise a video display's picture. If you look very closely at your monitor, you can see its pixels.
Why are flat screen monitors preferable..?
Flat screen monitors are more valued for their ability to reproduce more accurately the printed page. They also tend to have less glare, since flat surfaces displays have fewer angles to pick up and reflect glare. CTX Professional PureFlat Series monitors are flat screen monitors.

Interlaced versus non-interlaced. Which is better...
Simply put, non-interlaced monitors (or rather, non-interlaced video modes) are considered superior because they tend to produce less flicker.
Why do interlaced monitors tend to produce more flicker...
The reason is non-interlaced monitors/video modes use only one pass or "sweep" of the electron gun, whereas interlaced monitors/modes use two passes or "sweeps" to display the same image. With interlaced monitors/modes, one set of lines is made on the first sweep then, a split second later, a second sweep creates more lines to fill in areas left open after the first sweep. More accurate results can be had when one sweep, rather than two sweeps, produces the image. Non-interlaced monitors are capable of interlacing, but the display results are better with non-interlacing; thus, there is no sense or desirability to use interlaced modes on non-interlaced monitors.
What do I do if one edge of the screen is lower than the other end of the screen?
This is means that the magnetic field from the earth or a magnetic source near the monitor may interfere with the magnetic field generated by the monitor so that the image may appear slightly rotated or tilted. Use the tilt function in the OSD to make the adjustment.

What is the advantage of anti-glare monitor? What does ARAG stand for ...
Anti-reflective, anti-glare monitors alleviate eyestrain by eliminating shine. Like reading a book in strong sunlight, it can be difficult to look past the shine of reflected light to the words or pictures beneath. ARAG, an acronym for Anti-Reflective, Anti-Glare, is a trademarked process by which image quality is retained despite the fact that actually less silica (than other methods) is used to coat the screen to prevent glare. The ARAG coating method is noted for excellent image retention and clarity of viewing.
What is the difference between tube geometry such as "spherical", cylindrical" and "flat"..?
There are flat screens (which are truly flat or nearly flat to all four corners);
spherical, which bow at all four corners like a section of an inflated balloon, and cylindrical, like a section of a soda can which is rounded along the vertical axis but flat along the horizontal axis.
What is VESA ...
VESA, which stands for Video Electronics Standard Association, is a group of manufacturers who define standards for video displays for the personal computer industry. One famous standard which VESA proposed and the computer display industry has adopted is 75Hz vertical scan frequency 800 x600.

What is VGA ...
VGA is short for Video Graphics Array, and is an IBM-defined resolution of 640 x 480 with 16 colors.
What is SVGA ...
The generally accepted definition of Super VGA (SVGA) is 800 x 600 with a minimum of 256 colors at that resolution.
Why do my games only run as high as 800x600 and 256 colors ...
Games usually involve heavy graphics that may prove so resource intensive that the play would be terribly slow if higher color amounts were to be programmed in for use.

What does "resolution" mean ...
While resolution can mean different things depending on the context in which the
word is used, when referring to monitors and video cards it is most commonly used to refer to display format, e.g., 640 x 480, 800 x 600, 1024 x 768, etc. In a more general sense, it refers to display quality/clarity, which can hinge on dot pitch, pixel convergence, pixel depth, and other factors.
Will there be a problem with power standards overseas ...
CTX monitors automatically switch (called "autoswitch") to compensate for varying standards amongst different countries in the world. There shouldn't be a problem running any CTX monitor in any country.
Is there a problem using my monitor in another country ...
While CTX monitors automatically switch to accommodate all major power standards for everyday use, it is always wise, especially where intended use will be in developing countries, to check on that country's power quality (tourist guidebooks, travel agents, and embassies can help) before using the computer in that environment. Plan ahead, and purchase adapter plugs, line conditioners, and UPS's (un-interruptible power supplies) as necessary. Your computer cannot automatically to compensate for the power quality and plug shapes you will encounter where you are going. These devices are sold in the US at computer stores. Inflight travel magazines often advertise accessories to adapt your system unit and monitor to your destination's power as well. Note: Phone line transmission quality in third world countries can be a problem for modem users.

What does the term "green monitor" refer to ...
The term "green" is used in the environmentally friendly sense. Green monitors have low power consumption. The term has fallen into disuse; people now talk in terms of various ratings and standards, which indicate lower power consumption levels than older monitors.
What is the advantage of having an MPR II monitor ...
The MPR II rating signifies compliance with Swedish standards organization's rating for low electromagnetic emissions. MPR-II rated monitors are less likely to cause health-related problems given that there may be a link (it is still controversial) between EM radiation and a variety of human illnesses.
What is the advantage of having a TCO-rated monitor ...
The TCO rating signifies compliance with the German standards organization's rating for low electromagnetic emissions. While the TCO rating does not supplant the MPR-II rating (they are issued by different agencies), TCO is considered a more stringent rating than MPR-II.
What do I use to clean by screen on my CRT monitor?
The surface of the CRT is coated with high-tech anti-reflection film to reduce radiation. To protect your screen, please do not use any coarse fabric, or any solvent containing alcohol, benzene and alkali to clean the surface of the CRT. If necessary, please use only soft cloth like flannel or velvet with mild detergent to clean the screen.
