Rackmount Monitor Buyer's Guide: How to Choose a Rack Mount Monitor for Your Server Room

A rackmount monitor is a display, and usually a keyboard and pointing device, built into a 1U or 2U drawer that slides into a standard 19-inch server rack. Instead of a separate monitor, keyboard, and mouse at every server, one rack mount monitor gives IT teams a single console to view and control every machine in the rack, folding flat when not in use to reclaim space. KVMSwitchTech stocks 17", 19", and 20" rackmount monitors, dual and triple display models, high-brightness panels, short-depth drawers for shallow racks, and IP-enabled units for remote KVM access over Cat5.

Step 1: Choose your form factor (drawer vs. LCD-only)

Decide whether you need a full rackmount keyboard and display drawer (a "KVM console drawer") or a display-only rackmount LCD. Console drawers integrate screen, keyboard, and touchpad or trackball in one slide-out unit; LCD-only drawers pair with your own keyboard or a separate KVM. If you manage many servers from one console, add a built-in KVM switch.

TypeWhat's includedBest for
KVM Console DrawerLCD + keyboard + touchpad/trackballSingle-console control of one or many servers
Rackmount LCD (display only)Flip-up LCD in a 1U drawerMonitoring where a keyboard is not needed
Drawer with built-in KVMLCD + keyboard + 8/16-port KVM switchControlling multiple servers from one drawer
Dual / triple displayTwo or three panels in one drawerControl rooms, monitoring walls, NOCs

Step 2: Pick the screen size and resolution

The most common rackmount monitor sizes are 17" and 19" (typically 1280x1024), with 20" units reaching 1600x1200 and widescreen 1080p (1920x1080) and 1920x1200 options for detailed work. Match resolution to what your servers and KVM output natively so the image stays sharp and correctly scaled.

Step 3: Confirm the video interface

Rackmount monitors ship with VGA, DVI-D, HDMI, or DisplayPort inputs, and some support composite or S-Video for legacy AV gear. Choose a unit whose input matches your servers or KVM switch to avoid adapters. For a display-only drawer, see our 1U Rackmount LCD range.

Step 4: Measure rack depth (standard vs. short depth)

Full-depth drawers can be too long for wall-mount racks, network cabinets, and shallow enclosures. Measure the usable mounting depth of your rack before ordering, and choose a short-depth rackmount monitor when space behind the rails is limited.

Step 5: Match the interface and power to your environment

  • USB or PS/2 – pick the keyboard/mouse interface your servers accept; combo USB + PS/2 models cover mixed fleets.
  • Cat5 / IP KVM – add a Cat5 or IP-enabled console to switch many servers and allow remote access over the network.
  • DC power options – 12V, 24V, and 48V DC models suit telecom and industrial power environments.
  • High brightness – choose a high-brightness panel for control rooms and areas with bright ambient light.

Frequently Asked Questions

What is a rackmount monitor?

A rackmount monitor is an LCD display, often combined with a keyboard and touchpad or trackball, built into a 1U or 2U drawer that slides into a 19-inch server rack. It gives IT teams a single fold-away console for the servers in the rack.

What is the difference between a rackmount monitor and a KVM console drawer?

A KVM console drawer includes the display, keyboard, and pointing device in one slide-out unit, and often a built-in KVM switch to control multiple servers. A display-only rackmount LCD provides just the screen.

What size rackmount monitor should I choose?

17" and 19" units (1280x1024) cover most server rooms; 20" units reach 1600x1200 and widescreen models support 1080p or 1920x1200 for detailed monitoring. Match resolution to your KVM or server output.

Will a rackmount monitor fit a shallow or wall-mount rack?

Only if you choose a short-depth model. Measure the usable mounting depth of your rack first, then select a short-depth rackmount monitor drawer for cabinets and wall-mount racks.

Can one rackmount monitor control multiple servers?

Yes. Choose a KVM console drawer with a built-in 8- or 16-port KVM switch, or an IP/Cat5 KVM model to switch between and remotely access many servers from one console.

What video connections do rackmount monitors support?

VGA, DVI-D, HDMI, and DisplayPort are all available, with composite and S-Video on select AV models. Pick the input that matches your servers or KVM switch to avoid adapters.
