vertical refresh rate การใช้

• However, low-end circuitry rarely allows the vertical refresh rates beyond 75 hertz ( cycles per second ) that flicker-sensitive souls like me prefer.
• The disadvantage of progressive scan is that it requires higher bandwidth than interlaced video that has the same frame size and vertical refresh rate.
• One other thing to look for : a high vertical refresh rate, the speed at which the screen redraws images based on new information.
• Out of the box, the software is typically set for 640 dots horizontally, 480 vertically, 256 colors and a vertical refresh rate of 60 hertz.
• Finally, " vertical refresh rate, " measured in hertz ( Hz in your manual ), tells you how many times per second the electron beam repaints the image.
• Look for a monitor with a " dot pitch " of 0.28 millimeters or less and a vertical refresh rate of at least 75 hertz at 1, 024-by-768 resolution.
• Whichever size monitor you choose, make sure its scanning-frequency range matches your graphics card's so that it can achieve a flicker-free, non-interlaced vertical refresh rate of 75Hz or higher.
• The monitor should be noninterlaced, measure at least a nominal 15 inches, have a dot pitch of 0.28 millimeters or less and handle vertical refresh rates of at least 72 hertz.
• Look for a monitor with a " dot pitch " of 0 . 28 millimeters or less and a vertical refresh rate of at least 75 hertz at 1, 024-by-768 resolution.
• For example, if a cathode ray tube's vertical refresh rate is set to 60 Hz, most screens will produce a visible " flickering " effect, unless they use phosphor with long afterglow.
• They had a RAMDAC with a bandwidth of 230 MHz capable to display resolutions with 80 Hz vertical refresh rate up to 1152?00 pixels at 24 bits or 1600?200 pixels at 16 bits.
• The monitor should be noninterlaced, measure at least a nominal 15 inches, have a dot pitch of 0 . 28 millimeters or less and handle vertical refresh rates of at least 72 hertz.
• At the 1, 024-by-768 resolution at which 17-inch monitors typically look best, it can deliver a vertical refresh rate of 106 Hertz, which is probably more than your computer's video circuitry is willing to attempt.
• To obtain a vertical refresh rate higher than 40 Hz, this resolution requires more bandwidth than a single link DVI supports and requires UXGA ( 1600?200 ) 20 in monitors turned vertically on either side.
• For example, a multisync display may support a range of vertical refresh rates from 50 to 72 Hz, or from 96 to 120 Hz, so that it can display all standard capture rates by means of an integer rate conversion.
• The unit can display 640 by 480 pixels at millions of colors at an acceptable 72-hertz vertical refresh rate, but its only other graphics mode is 800 by 600 at a flickery 56 hertz, a potential problem as programs begin to demand higher resolutions.
• For instance some laptop LCD panels cannot be ( easily ) switched to anything but a 60 Hz refresh rate, and some LCD displays with DVI input refuse to accept digital input signal if its vertical refresh rate does not fit between 58 and 62 Hz.
• In revision 1.2, released in 2013, a new RB2 mode has been added which further reduces blanking interval and allows for unlimited vertical refresh rates, 4K / 5K / 8K resolutions, 0.001 MHz pixel clock precision, and 1000 / 1001 modifier for ATSC / NTSC video timing modes.
• If Pin 4 was connected to ground, the computer would detect this and boot into the high-resolution monochrome video mode that was not user-selectable and only worked with specially designed monitors ( the vertical refresh rate being 71 Hz as opposed to 50 / 60 Hz for colour modes ).
• When confronted with the jargon of the monitor world, insist on a dot pitch of . 28 millimeters or less, a maximum resolution of at least 1, 028 by 764 pixels at a vertical refresh rate of at least 75 hertz, the ability to memorize settings you use most often, compliance with " Energy Star " power-saving standards and an antiglare screen coating.
