Getting monitor setup right in a home office is primarily about position: height, distance, and relationship to the room’s light sources. Most monitors arrive with adequate display quality; the errors that cause eye strain and neck pain are almost always positional rather than technical. For choosing the right desk to support your monitor configuration, see the home office desk setup guide.
Single monitor vs. dual monitors
Before configuring the setup, the first decision is whether a single monitor or dual monitors better fit the workspace and workflow.
Single vs. dual monitor for a home office
| Factor | Single monitor | Dual monitors |
|---|---|---|
| Desk space required | 60–80 cm width | 100–145 cm width (arm reduces lower bound) |
| Cable management complexity | Low — one display cable, one power | Higher — two of each; USB hub often needed |
| Use case fit | Focused writing, calls, light multitasking | Reference-heavy work, coding, spreadsheets, design |
| Cost | Lower upfront | Higher — second monitor + arm recommended |
| Ergonomics | Simpler — one screen to position | Requires planning to avoid neck strain from secondary screen |
| Clutter on desk | Minimal | More cables; arm helps significantly |
A single large monitor (27–32”) often covers the same screen area as two smaller monitors while being easier to position correctly and simpler to manage. Dual monitors are most useful when you regularly work with two distinct sources — code and documentation, a spreadsheet and email, a reference document and writing.
Correct monitor height
Incorrect monitor height is one of the most common ergonomic errors in home offices. Most people set their monitor too low.
Monitor height reference guide
| Setup | Target position | How to check |
|---|---|---|
| Single monitor | Top of screen at or just below eye level when seated normally | Sit in normal working posture; eye level should hit the top quarter of the screen |
| Dual monitors (matched) | Both top edges aligned at same height; top edge at or just below eye level | Check that you do not tilt the head up to read either screen |
| Laptop on stand | Bottom of raised screen at approximately eye level (screen tilts back to face you) | Laptop keyboards are not at desk height — stand + external keyboard is required |
| Monitor with built-in stand | Adjust stand to maximum height first; add a monitor riser if still too low | Risers of 10–15 cm are common corrections for desks without height-adjustable stands |
If the monitor stand cannot reach the correct height, a monitor arm solves this — arms provide full height adjustment that fixed stands do not. A monitor riser (a platform under the stand) is a low-cost alternative if an arm is not in the budget.
Correct monitor distance
The optimal distance from eyes to screen is 50–70 cm for most monitor sizes. Sitting closer forces the eyes to work harder; sitting further reduces the ability to read text at standard sizes.
A practical field check: extend your arm straight forward from your seated position. Your fingertips should roughly touch the screen surface, or fall within a few centimetres. If your arm is fully extended and the screen is still far beyond your reach, you are sitting too far away.
For larger monitors (32” and above), the comfortable distance increases — 70–90 cm is appropriate to avoid excessive head movement when reading content at the edges of the screen.
Monitor position relative to windows
Window placement relative to the monitor affects both glare and eye comfort throughout the working day.
Monitor placement and window relationship
| Window position | Effect | Recommendation |
|---|---|---|
| Window directly behind monitor | Bright background behind screen; increased apparent contrast; glare on screen | Avoid — use a blind or reposition desk |
| Window directly in front (you face window) | Direct light into eyes; screen washed out in daylight | Avoid — rotate desk 90 degrees |
| Window to the left or right (side) | Natural light illuminates desk without shining at or behind screen | Preferred position for most setups |
| No window (windowless room) | No glare from natural light; artificial lighting controls everything | Use 4000K ambient light; add bias lighting behind monitor |
See the screen glare reduction guide for specific fixes when repositioning the desk is not possible.
Monitor arm vs. stand
Monitor arm vs. desk stand
| Feature | Monitor arm | Included desk stand |
|---|---|---|
| Height adjustment range | Full range — typically 30–50 cm vertical travel | Limited — 5–10 cm on most stands; none on fixed-height stands |
| Desk surface recovered | Stand footprint (~20 × 20 cm) cleared | Stand remains on desk surface |
| Viewing angle adjustment | Full tilt, pan, and rotation | Tilt only on most stands |
| Desk depth flexibility | Monitor position adjustable forward and back | Fixed depth — monitor sits where the stand is placed |
| Cable management | Cables route through arm; cleaner desk | Cables hang freely from back of monitor |
| Cost | £30–£120 for a quality single arm | Included with monitor |
A monitor arm is worth the cost for most home office setups: it recovers desk surface, provides full height adjustment, and makes cable routing significantly cleaner. The main consideration is desk edge thickness — most clamp-style arms require at least 10 mm of desk edge and work up to 80 mm.

Frequently asked questions
How high should a monitor be in a home office?
The top edge of the monitor should sit at or just below eye level when you are seated in your normal working position. Looking at the top of the screen means you will naturally look slightly downward to read content — which is the correct, low-strain viewing angle. A monitor positioned too low forces the neck to bend forward; one positioned too high causes upward neck tilt.
How far should you sit from a monitor?
50–70 cm for most 24"–27" monitors. A practical check: seated at the desk, extend your arm forward — your fingertips should roughly reach the screen surface. For 32" monitors and larger, 70–90 cm is more comfortable to avoid head movement when tracking content at the screen edges.
Is a monitor arm worth it for a home office?
Yes for most setups. A monitor arm recovers the stand footprint (~20 × 20 cm of desk surface), provides full height adjustment that fixed stands cannot match, and makes cable management cleaner. The main cost is the arm itself (£30–£120 for a quality single arm) and the requirement that your desk edge is thick enough for the clamp — most are, at 25–40 mm.
Should the monitor face the window or be side-on to it?
Side-on to the window is the correct position. A window directly behind the monitor creates a bright background that strains the eyes. A window directly in front causes glare and washes out the screen in daylight. A window to either side provides natural light to the workspace without creating reflections on the screen or competing with it for brightness.
