診断プロトコル

ディスプレイテストの実施手順 (01, 02, 03)

01

準備

画面の汚れを拭き取り、環境光自動調整をオフにして、ネイティブ解像度と最大リフレッシュレートに設定します。

02

実行

全画面モード (F11) に切り替え、コントロールバーを使って各種テストパターンを順に表示します。

03

評価

部屋を暗くし、異なる視野角からムラやドット抜け、残像を観察してガイドと照合します。

ハードウェアアーキテクチャ

液晶・有機ELパネル技術の比較

プロフェッショナルIPS (In-Plane Switching)

卓越した色再現性と視野角。リファレンスモニターに最適。暗所でのわずかなIPSグローが発生する場合があります。

ゲーミングIPS (Fast IPS / Nano IPS)

ゲーミング向けの高速リフレッシュレートと応答速度。ただしVAと比較して静的コントラスト比は控えめです。

VAパネル (Vertical Alignment)

引き締まった深みのある黒と高コントラスト (3000:1+)。湾曲モニターに多い一方、暗所での黒残像に注意が必要です。

OLED (有機EL) & QD-OLED

自発光ピクセルによる完全な漆黒、超高速応答、無限のコントラスト。自動輝度制限 (ABL) の影響を受けます。

Technical FAQs & Helpful Content

Frequently Asked Questions (Analog Stick Drift & Circularity Error Diagnostic Tool)

この診断機器、校正手順、ディスプレイ技術規格について知っておくべきすべての情報。

01.What is analog stick drift?
Stick drift is uncommanded cursor or in-game camera movement caused by worn potentiometer resistive tracks, dust, or weakened centering springs.
02.What is analog stick circularity error %?
Circularity error % calculates average percentage deviation of sampled outer bound points from an ideal unit circle (r = 1.0).
03.What is acceptable circularity error % for gaming controllers?
Factory calibrated controllers achieve under 5-8% circularity error; uncalibrated or worn sticks exceed 15-25% error.
04.How does the online stick drift test work?
Samples X/Y coordinates from W3C Gamepad API in real time, calculating centering drift offset when sticks are released.
05.Why do PS5 DualSense and Xbox controllers develop stick drift?
Traditional ALPS potentiometers use physical wiper contacts that wear down resistive carbon tracks over 400+ hours of gameplay.
06.What are Hall Effect analog sticks and why are they immune to drift?
Hall Effect sensors use magnetic sensors instead of physical contacts, completely eliminating mechanical contact wear.
07.How do I fix analog stick drift on my controller?
Fixes include cleaning potentiometers with 99% isopropyl alcohol, adjusting in-game dead-zones, or installing Hall Effect replacement modules.
08.What is a dead-zone setting in games like CS2, Call of Duty, and Fortnite?
Dead-zone settings create an inner threshold circle ignoring small stick movements, preventing subtle drift from affecting gameplay.
09.Can I test both Left and Right analog sticks simultaneously?
Yes, dual polar plots track both Left (Axes 0/1) and Right (Axes 2/3) stick boundaries.
10.How do I export my stick drift health passport?
Click 'Export Passport' to download a cryptographically signed JSON report certifying your analog stick circularity score.
