Wide LCD Monitor

Q1. 

My new Studioworks monitor isn't listed in the Monitor download driver section.

You can download the driver for your monitor from our website, but you can also use the standard plug and play driver listed under standard monitor types. All of the Studioworks monitors use the Plug-and-Play driver.

Q2. 

Can you confirm that this monitor is Y2000 compliant?

Our products satisfy the BSI(British Standards Institution) Y2K conformity definitions listed below. Our position regarding the rules follow after the arrow marks below the rule: Rule 1 : No value for current date will cause any interruption in operation. => There are no current dates in our products. We have only manufactured date in the EDID data and it will not be changed once saved. Rule 2 : Date-based functionality must behave consistently for dates prior to, during, and after year 2000. => Our products do not have any date-based functions. Rule 3 : In all interfaces and data storage, the century in any date must be specified either explicitly or by unambiguous algorithms or inferencing rules. => In EDID data, the year is expressed by 1 byte hex code according to VESA standard and it does not have Y2K problems. VESA standard defines the year in EDID data: value stored = year of manufacture - 1990. Ex) 09 = 1999 - 1990 0A = 2000 - 1990 FF = 2245 - 1990 Rule 4 : Year 2000 must be recognized as a leap year. => It is not applicable to our products because there are no dates in our products but year or year and week.

Q3. 

What are MPRII and TCO95?

LG Monitor's philosophy has always been to comply with the strictest ergonomic and ecological standards,and we were the first monitor manufacturer to develop and market a full range of high end display monitors that adhere to MPR II and TCO 1992. At the present time we are striving for TCO`95. All the CRT monitors on the market today release Alternating Electric and magnetic fields that are classified as non-ionizing radiation (not to be confused with ionizing radiation that are X-rays and radioactive). MPR are guidelines established by the Swedish Agency for Administrative Development (Statskantret),giving recommended acceptable emission values for magnetic/electric radiation and static electricity. MPR I was established in 1987 as a voluntary guideline. LG Monitor was among the first manufacturers of displays to meet or exceed its recommended emission limits. MPR II was established in 1990 and is an even stricter standard than its predecessor. The TCO standard was first established in 1989. TCO are the initials (in Swedish)for the Swedish Confederation of Professional Employees. This confederation has established the strictest standards for computer display AEF and AMF emission levels in the world. The TCO 1992 standard also includes power saving and compliance with European fire and electrical safety requirements. TCO `95 goes even further by incorporating recycling requirements as well as making the manufacturing process free of harmful substances.

Q4. 

What is the best setting for my monitor?

LG monitors are Multi-Sync monitors. There is no one exact frequency required for any resolution. In general, we strongly recommend using VESA timings, because we know our monitors operate properly in that mode. However, if you cannot follow these timings, all our monitors will operate within a wide range. Furthermore, please check in the specifications paragraph of the user's manual for the recommended resolution. A common misconception is that there are LG monitor drivers for video cards. This is little more than just a list of scan frequencies and resolutions (an *.inf information file). * If possible, use a NON-interlaced selection. * If possible, use a 80Hz (or higher) high refresh rate. * If your card does not offer this range, 70Hz will work, but do not go under this rate as you might encounter some flicker. * high refresh rates of 90Hz (non-interlaced) or higher may be used as long as the monitor supports those rates. * There is no need to change sync polarity, any combination will work correctly. * You cannot damage the monitor with an incorrect video card set up. Feel free to experiment. * Even if the card allows you to adjust the size of the image using controls on the video card, always use the monitor's controls to adjust the image size. * The best way to see if the monitor will work with a given resolution and rate is to compare the horizontal and vertical frequencies of the Video card to the monitor's range. * If the frequencies are within the correct range, the monitor should operate.

Q5. 

How to set refresh rate/frequency timing?

Please follow the steps. (Note: Some steps may differ slightly depending on OS) 1. In the Windows desktop, click Start. 2. Choose Setting. 3. Choose Control Panel. 4. Click the Display control panel. 5. In the Display control panel dialog, click the Setting tab. 6. Click Advanced Properties. 7. Click the Adapter tab. 8. Select refresh rate in the list. It is usually correct to select the highest rate available. 9. Click OK to exit the Advanced Properties dialog. 10.Click OK to exit the Display control panel dialog.

Q6. 

My monitor manual lists that it is capable of 80 modes

The monitor is capable of these modes, however your video adapter card may not be fully backward compatible with the modes and the refresh rates that the older monitor supports. If the standard drivers do not enable the monitor to work, there is a hardware incompatability between the video adapter card and the monitor. You can check with the video adapter card's manufacturer to see if they have any drivers that allow to you manually set the refresh rate to a lower frequency. The frame buffer is the video memory that is used to hold the video image displayed on the screen. The amount of memory required to hold the image depends primarily on the resolution of the screen image and also the color depth used per pixel. The formula to calculate how much video memory is required at a given resolution and bit depth is quite simple: Memory in MB = (X-Resolution * Y-Resolution * Bits-Per-Pixel) / 8 Video memory requirements for the frame buffer for various resolutions and colordepths : Please see the attached file.

Q8. 

What is Horizontal Scanning Frequency?

The rate (in kHz) of how many times an electron beam traces across horizontal lines of phosphor dots in one second, painting the image. Monitors with higher horizontal rates can run at higher resolutions.

Q9. 

What is focus?

Focus is highly dependent on the quality of both the deflection yoke and the electron beam gun. Implementation of a high quality deflection yoke sensures that the electron beam will strike the proper position on the CRT surface. Implementation of a high quality electron beam gun and focus lens are vital to ensure that the shape of the beam when it strikes the screen is as close as possible to being perfectly round, not oval or elliptically distorted. Loose focus can be caused by the physical properties of the CRT display. The electron beams traveling to the corners of the display are longer than those traveling to the center. Therefore, the display circuitry must dynamically compensate for shorter and longer focal lengths of the electron beams as they scan the screen. Also, the beam shape can distort as it passes through the magnetic field generated by the Deflection Yoke.If this distortion is not compensated for by a Dynamic Focus Lens, the focus quality, especially at the edges and corners of the display, will greatly deteriorate. Sharp focus also depends on the amount of current needed to write the image to the screen. When more current is needed to write the image to the screen,the electron beam becomes some what thicker. This causes the beam to illuminate areas around the spot for which it is intended. This illumination of stray phosphor dots causes the edges of the intended image to blur. Stripe Mask CRT displays have an advantage over Shadow Mask displays because:more light can pass through the Aperture Grill of the Stripe Mask CRT (LG StudioWorks 78D) than can through a conventional Shadow Mask.Therefore, bright images can be displayed with less current, allowing for better focus levels.

Q10. 

What is Convergence and Mis-convergence?

Convergence is the ability of the three electron beams (R, G, & B) to come together at a single spot on the surface of the CRT. Precise convergence is necessary as CRT displays work on the principal of additive coloration: when Red light,Green light,and Blue light are added in equal amounts they will form a white spot or line. The absence of all color makes a black spot or line. Variation of the relative strengths of the R, G, and B electron beams creates color variation.When the individual electron beams (R, G, & B) do not converge perfectly mis-convergence error becomes readily apparent. Mis-convergence shows up as shadows which appear around text and graphic images. If a white line is drawn on screen,for example, blue and red shadows may appear either above and below the line or on both sides. The dispersion of the magnetic field from the Deflection Yoke.Convergence depends highly on the capability of the Deflection Yoke to guide each electron beam to the proper location. If a poor quality Deflection Yoke is employed, or if there is outside magnetic influence affecting the performance of the Deflection Yoke, mis-convergence becomes apparent. Mis-convergence can be caused by a Mis-alignment of, or damage to, the Shadow Mask. Since convergence highly depends on the electron beam striking the proper place on the CRT surface, mis-alignment of the Shadow Mask could result in mis-convergence.
