Using a TV as a PC monitor: the best models, and what size works at a desk

A big TV on a desk is tempting: four times the pixels of a 1080p monitor, HDR, and often a lower price per inch than a large monitor. It works well if you get three things right: the inputs, the size for your distance, and the panel type for your use.

Size for your distance

At a desk you sit much closer than to a living-room TV, so size limits come quickly. OSHA’s office guidance puts monitors 20–40 in from your eyes, with the screen’s center 15–20° below eye level. A TV also fills a much wider share of your view. Using the same 30–40° rule we apply to living rooms:

Many people happily game on a 42- or 48-inch OLED at 3 ft, wider than these angles, because games are designed to put the action in the center. For reading and spreadsheets, stay close to the table. For wider fields of view in games, NHK’s research found the “sensation of reality” grows with viewing angle up to about 80–100° (Hatada et al., 1980), but that’s a different goal from comfortable reading.

What to check in the specs

• Refresh: 120 Hz is enough for consoles; for PCs, 144–165 Hz on the HDMI 2.1 inputs (see 120 vs 144 Hz).
• VRR: G-Sync Compatible or FreeSync Premium, for tear-free variable frame rates.
• DisplayPort: almost no TV has one. The Hisense U8 has a USB-C DisplayPort input, which suits PCs without an HDMI 2.1 port.
• Chroma 4:4:4 in PC mode: without it, small colored text looks fuzzy. Spec sheets rarely say; lab reviews test it.
• Small sizes: LG and Samsung make 42- and 48-inch OLEDs that suit desks better; they aren’t in our catalogue yet, so our picks below start at 55 inches.

Our picks

Native 165 Hz, three HDMI 2.1 inputs plus USB-C DisplayPort, Mini LED (no burn-in from a taskbar), anti-glare panel. The most PC-friendly input set we list.

Mini LED, four inputs to 165 Hz, Glare Free matte-type screen, 1.1 in deep: a good desk or wall option in a room with windows.

Four inputs to 144 Hz, G-Sync and FreeSync listed, near-instant response. Use it for games and media; if it will show a desktop for hours a day, read OLED burn-in first.

OLED at up to 165 Hz on all four inputs, with Glare Free. The same burn-in caution applies.

Setup tips

1. Rename the input to PC (on LG and some others) or enable PC mode for full chroma and minimal processing.
2. Set Windows scaling to 150–200% at 4K on 42–55 inches; text stays sharp and readable.
3. Turn on VRR in the TV and the GPU driver; cap frame rate a few fps below the TV’s maximum.
4. For OLEDs, use a dark theme, auto-hide the taskbar and let the screen saver run.
