去親眼睇你有冇彩虹眼
有又不停睇到跟本用唔到 dlp 機
幾靚都冇用

真係買都買 x pro 貴p1 小小 upgrade 版
平幾千有白色p2
Xpro p1 p2 係同一系，p1四角唔利係事實，即做唔到文書
打機又唔夠快(其他4k dlp 都咁上下），唯一係主打睇片睇電視

重有靚仔benQ同高階LG

睇 demo epson HDR 可自行調較畫質又幾好

另外想問問如果用超短投，咁中置應該點擺位好呢，兩件器材擺位重叠左😅

利用機頂同幕底 and 幕面同機背
呢一個空間放隻不要太大的中置

原理同相機一樣鏡頭越大越易做到好鏡頭
再加上冇咁wide變左投距換質素
咁P1用嚟睇片其實又冇咩問題

之前真係冇諗過optoma p1咁多問題，
竟然係四角對焦會唔清，
真係完全想像唔到大拿拿三萬蚊部機會係咁樣質素，
想攞嚟打機都唔盡興…🤦🏻‍♂️🤦🏻‍♂️🤦🏻‍♂️

就算普通短投好多時都會有四角會矇嘅問題
其實呢啲鏡頭問題超短會更加嚴重
當然同廠同一款型啒都會有QC問題而令質素參差
鏡頭質素好影響的

咁冇論review 或者 promotion 都冇用嚟做呢兩樣測試
真係初頭 firmware 去到80/90ms 都唔會買嚟主打game
就算新 firmware 去返60/70ms 都唔適合插電腦打game
Console game 都還可以
你都話3萬蚊唔係主要睇片真係唔會買佢用嚟做文書
Click 完左上角 save 再click 右下角 zoom 眼球要移動100寸對角

我係主要睇片，
從來都冇講過做文書😅
我用PS4 打機咁都唔得？

師兄其實唔係個個都好似你對投影機咁有研究，
作為一般用家真係冇乜其他辦法/上網得知有P1個鏡頭對焦四角依個問題😅😅😅
普通玩家大多數都係喺相信零售鋪頭嘅說話。

唔係話唔得但要選呢d時延短

https://www.benq.com/zh-hk/proje ... e-cinema/w1120.html

同一間廠高階機，都冇講時延

https://www.benq.com/zh-hk/proje ... -cinema/x12000.html

中階都冇講

0.47 dlp 靠不停重叠影像原理 ,每秒60格加上下左右搖動4次
先唔計佢要點處理左個訊號先去到 dlp chip
就只係塊0.47 dlp 要做咁多野先重叠到個畫面嚟講
想時延短嘅機會唔高

咪賣左架P1 加3000買架 epson
不過8400都冇講係幾多 ms

玩邊類game 發現最大問題？
賽車應該ok ga? 槍game 就應該窄d?
但成100吋冇4米距離會唔會打到頭暈？

Input Lag. Input lag was measured at 1080p/60 and 2160p/60 with a Bodnar lag meter. The numbers appeared to be the same for all picture modes, and neither engaging the PureMotion frame interpolation nor the geometric correction appeared to affect the readings. Using the Game picture preset for measurements resulted in a reading of 121.8 ms with a 4K UHD signal, and 171.6 ms for 1080p/60. These are high numbers that would not be recommended for competitive first-person shooter online gaming. Optoma says its planned mid-June firmware update will address this with the introduction of a "Game Mode" toggle setting that will increase the internal refresh rate while bypassing the SmartFIT and PureMotion circuitry. This is expected to result in 70-75 ms input lag for both 2160p/60 and 1080p/60 signals. That level of input lag would be considered more acceptable for casual gaming. We'll remeasure and edit our review as needed after the update.
