# Fuzzy text on displays with macOS

## Introduction

Just like a monitor, a pen display contains a display panel with a native display resolution.

## Typical resolutions

Modern pen displays mostly use a small number of resolutions. The vast majority of pen displays use these three resolutions:

* Full HD = 1920x1080
* 2.5K = 2560x1440
* 4K = 3840x2160

A few pen displays use resolutions such as 2560 x 1600.

## Considerations

### **Seeing pixels**

* Some people are very sensitive to seeing pixels.
* When drawing on a pen display, you'll be much closer to it than when you are using a monitor.
* So you might notice the pixels more due to this proximity.

### **Compatibility**

The resolution with the least compatibility issues is 2K. This format has the least issues with ports, cables, GPUs, adapters, etc. As you start getting into higher resolutions, you have to be more careful about compatibility and ensure everything is going to work.

For example:

* Not all HDMI cables support 4K
* Some laptops struggle to support an external 4K display
* Macintoshes have difficulty supporting 2.5K resolutions
* Some systems support the higher resolutions but not a high-enough refresh rate. For example one of my laptops supports 4K but only at 30Hz instead of the standard 60Hz.

## Pixel density: pixels per inch (PPI)

## **Picking between 2.5K vs 4K resolution**

People often ask about picking between these two resolutions. Overall, I think 2.5K is the best value for your money.

Especially at the 13" and 16" sizes, a 2.5K display delivers a massive increase over 2K. At these sizes, higher resolutions only provide very incremental benefits.

## My experience and recommendations

Based on my experience, here's what I think works. Overall, a PPI between 150 and 180 is what I think works best.

## Overview

macOS text rendering can fail to look right by default with certain combinations of sizes and resolutions. This can be addressed with an app called BetterDisplay.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.sevenpens.com/drawtab/guides/platforms/macos/display-resolution.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
