## What is Epson Setting Assistant?

Epson Setting Assistant is an app that automatically corrects the shape of a projected image by using your camera. 
By taking a shot of the projected pattern, the app automatically corrects distortion in the projected image and adjusts its shape to match the screen.


[Main Features]

1) Shape correction

The app adjusts the image to a rectangular shape or aligns it with a frame, such as a projector screen.

2) Unevenness correction

The app detects small surface irregularities, such as on a wall, and corrects distortion in the projected image.

1. Select [Installation] ([Installation] > [Geometry Correction Wizard]) from the projector's menu.

2. Open this app on your iPhone®, iPad®, or iPod® touch and select [Home] as the projector type to automatically connect to the projector.

3. Follow the on-screen instructions to take a shot of the projected pattern using the camera in the app, and the corrections will be completed automatically.


[For Business Projector (EB Series) Users: Using the App]

1. Select [Installation] > [Connect to Setting Assistant] from the projector's menu to project a QR code.

2. Open this app on your iPhone®, iPad®, or iPod® touch, select [Business] as the projector's type, and then scan the QR code to automatically connect to the projector.

### 1/5 — Would not connect

*2026-08-07*

I followed the instructions carefully but it would not connect.

### 1/5 — 接続がクソ

*2026-05-10*

EHシリーズの画面補正をアプリでしようとしたがプロジェクターとの接続が不安定すぎる。
日本メーカーとは思えないレベル。
何度も10回接続チャレンジして1回繋がればマシなレベル。

### 1/5 — アプリ補正がめんどくさすぎる

*2026-02-23*

アプリで補正しようとすると、絶対に1発で接続ができない、もしくは補正がエラーになる。
再起動を毎回しなくてはならないため、本当に煩わしい。本体に自動補正機能をつけろよと思う。
別のメーカーのものを買うか検討中。

### 1/5 — TOAST

*2026-02-02*

No longer works since November. Was supposed to get an update in January but has not come.

### 1/5 — Ne fonctionne pas

*2026-01-16*

Nul, reste bloqué une fois connectée au projecteur, ne permet de rien faire. Du coup rend le vidéo projecteur inutilisable. NE PAS ACHETER EPSON !

### 1/5 — Failure to connect iPhone to projector since firmware upgrade

*2025-12-21*

Screen says “Connected to iPhone” and iPhone shows a checkmark on the “Connecting to the projector”, but both devices never connect or move on to the next step in configuring the projector screen. This worked before the LS650 firmware update

### 5/5 — Impressive

*2025-11-29*

Wasn’t expecting it to be so simple and good the team involved in this well done 💪

### 1/5 — Just like many others

*2025-11-27*

INITIAL SETUP WAS EASY,ADJUSTED THE SCREEN WITH THE PHONE THE FIRST TIME,AFTER THE PROJECTOR GETTING UPDATED IT STOPPED CONNECTING AND NOW MY IMAGE IS NOT PROPERLY SQUARE…EPSOM YOU HAVE TO FIX THIS

### 1/5 — Not working after firmware update

*2025-11-21*

I bought a new LS650 and used this app to correct the distortion but sometime later, my projector installed all updates including firmware. After these updates, this app is connecting to my iphone but is not proceeding after that. I have tried another iphone and another android device, but this app is not working anymore. I will call customer service and update.

### 1/5 — I hate this

*2025-11-19*

I want my money back🤬😡
