Display selection considerations
Display selection considerations
Proper selection of user display is critical for the success of deploying
KVM Combiners. The following is based on experience gained during
deployment of product:
• Avoid using old CRT displays.
• Some projects invest significant resources in overall project design
and implementation but neglect display and peripherals. Users may
reject product if proper displays are not used with it. As large LCD
costs are dropping it is more feasible to retrofit user desktop
completely.
• Proper size of display is critical. To enable simultaneous work with
several Windows, it is recommended to use LCD displays larger than
22" diagonal size.
• Considering user work area, try to use the largest display possible.
• It recommended to use displays that adjust automatically to
resolution changes. This is essential to support Window
maximization.
• Native resolution of display should match output resolutions of
product.
• Display should support Video input according to console video
port/s.To be future proof, it is preferable to have displays support
DVI/HDMI and
DP input.
• It is recommended to have the user involved in display selection
process during evaluation and initial deployment.
• DVI-I to VGA adaptors cannot be used with product as it does not
support analog video.
