Q:
What kind monitors can display 800x600 modes or higher resolution mode?
Explain and Suggestion:
To display 800x600 resolution at 60Hz refresh rate, the monitor must be capable
of synchronizing a 31.5KHz horizontal scan rate (e.g., NEC 2A, 3D). At 72Hz
refresh rate, the monitor must be capable of synchronizing a 48.0KHz scan rate
(e.g., Sony HG 1304, NEC 4D, 5D, Seiko 1450).
To display 1024x768 interlaced mode; the monitor must be capable of
synchronizing a 35.5KHz horizontal scan rate (e.g., NEC 3D, Seiko 1430 or
1440). To display 1024x768 non-interlaced mode at 60Hz, the monitor must be
capable of synchronizing a 48.7KHz scan rate (e.g., Sony HG 1304, NEC 4D, 5D,
Seiko 1450).
To display 1024x768 non-interlaced mode at 70Hz, the monitor must be capable
of synchronizing a 56.4KHz scan rate (e.g., NEC 4D).
Q:
Windows screen won't come up, it kicks back to
DOS prompt. Why?
Explain and Suggestion:
Windows® 95
Inadvertently, certain configuration files (e.g., msdos.sys, and command.com)
have been changed in the system. Proceed to correct that, is re-boot the system
with a system (Windows® 95) formatted floppy diskette.
There are many reasons to causing the system booting-up with in-appropriated
steps. Base on Microsoft support wizard on their WEBsite, there are many
technical articles to help users with this subject, such as troubleshooting with
VXD errors, virus, Fatal exceptions, etc., more details cover on each issue are
descriptive and familiar with, and exclusively further to our support.
Q:
System hangs-up after installing video driver.
Explain and Suggestion:
Today, most video drivers are developed for 32-bit processing and may require a
channel to Code/Decode. Conflict between device drivers and TSR (terminate-
and-stay-resident) programs will inverted the display, and are particularly
effectual at crashing computer. The most
effective way to check for conflicts is to
replace with the original video driver, or delete and re-install the current video
driver to the system.
Accomplishing IRQs (Interrupt Request Query) settings or troubleshooting the
conflicts on hardware source may necessary. Most AGP video cards designed for
Plug-n-Play, that means video card IRQ's setup which controls by main board’s
(motherboard) circuitry and BIOS. Physically pulling out other devices from
system, and re-starts the computer. Confirm and modify your IRQ addresses with
qualified computer technician.
