無線同屏器哪個好

1、看外形

便攜無線同屏(ping)器，產品小巧，多(duo)(duo)選用HDMI接口，一(yi)般為長(chang)方形(xing)。帶天線類(lei)無線同屏(ping)器的外形(xing)與家用路由(you)器相仿，多(duo)(duo)支持HDMI+VGA雙插口，可同時(shi)輸出兩(liang)臺設備(bei)。

2、看品質

無線同(tong)屏器的主(zhu)要功能是(shi)(shi)通(tong)過(guo)移動終端設(she)備將(jiang)視頻(pin)、音(yin)頻(pin)、文件等(deng)內(nei)容同(tong)步至其它大屏設(she)備，選(xuan)購時，要看畫質是(shi)(shi)否(fou)清晰、是(shi)(shi)否(fou)支持(chi)雙頻(pin)Wi-Fi、實時同(tong)步是(shi)(shi)否(fou)有延時、是(shi)(shi)否(fou)包含(han)HDMI+VGA雙接口(kou)，是(shi)(shi)否(fou)支持(chi)安卓/蘋(pin)果/微軟(ruan)移動終端設(she)備。

3、看傳輸頻率

5GHz延遲小，傳輸速度快(kuai)，抗(kang)干擾能(neng)力強。2.4GHz較普遍，易(yi)被(bei)干擾。因此(ci)消(xiao)費者還應(ying)優先(xian)選(xuan)擇支持雙頻的(de)無線同屏器產(chan)品(pin)，暢快(kuai)無延遲。

4、看傳送距離

衡量無線同屏器的主要性能之一就是傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)距(ju)離(li)(li)，傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)距(ju)離(li)(li)又可分為(wei)可視傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)距(ju)離(li)(li)和(he)遮(zhe)(zhe)擋傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)距(ju)離(li)(li)。UWB技(ji)術，是傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)距(ju)離(li)(li)最(zui)短的一種無線技(ji)術，直線傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)距(ju)離(li)(li)為(wei)5米左(zuo)(zuo)右(you)，遮(zhe)(zhe)擋傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)無效(xiao)。WIFI技(ji)術，在(zai)保證(zheng)圖像(xiang)最(zui)小延遲及(ji)最(zui)佳分辨(bian)率的情況下，也(ye)只能夠傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)2~5米，遮(zhe)(zhe)擋傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)有效(xiao)。WHDI技(ji)術，傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)距(ju)離(li)(li)在(zai)30米左(zuo)(zuo)右(you)的范圍(wei)內，圖像(xiang)的分辨(bian)率非常高，遮(zhe)(zhe)擋傳(chuan)(chuan)(chuan)(chuan)(chuan)送(song)(song)(song)(song)有效(xiao)。

5、看品牌

大(da)品(pin)牌(pai)的(de)產品(pin)質量往(wang)往(wang)有保(bao)障，售后服(fu)務較好(hao)，生產工藝技術成熟，價格定位(wei)也(ye)(ye)合理，國(guo)家監管也(ye)(ye)比較嚴(yan)格，消費者可根據自己(ji)的(de)實(shi)際需求，選購(gou)合適(shi)的(de)知名品(pin)牌(pai)無線同屏器。

選購無線同屏器要注意什么

1、注意價格

無(wu)線(xian)同(tong)屏器(qi)(qi)(qi)并非(fei)價格(ge)越(yue)高越(yue)好(hao)，還應看(kan)個人的(de)(de)實際用途。如果僅僅是為了(le)簡(jian)單(dan)的(de)(de)投屏，則(ze)不(bu)(bu)妨選擇一款價格(ge)適中的(de)(de)產品。不(bu)(bu)得不(bu)(bu)說，隨著手持(chi)設備(bei)同(tong)步大尺寸(cun)屏幕方式的(de)(de)增多(duo)，無(wu)線(xian)同(tong)屏器(qi)(qi)(qi)的(de)(de)確(que)處(chu)境較(jiao)尷尬。但無(wu)線(xian)同(tong)屏器(qi)(qi)(qi)具(ju)備(bei)更好(hao)的(de)(de)畫質，畫面延遲小，操作(zuo)較(jiao)簡(jian)單(dan)等(deng)特性，體驗相比同(tong)屏類軟(ruan)件要好(hao)得多(duo)。

2、注意質量

同(tong)(tong)屏器門檻低，市面上(shang)同(tong)(tong)樣不乏一些(xie)低質(zhi)(zhi)產品(pin)。此類產品(pin)僅僅是價格(ge)低，但不具(ju)備(bei)雙頻WiFi、畫質(zhi)(zhi)差、畫面有延(yan)時，體驗較差，質(zhi)(zhi)量堪憂(you)，消(xiao)費者選購時還應認準(zhun)大品(pin)牌產品(pin)。

3、注意使用場景

許多用(yong)戶對于同(tong)屏(ping)(ping)器(qi)(qi)的(de)了(le)解僅處(chu)于參(can)數上(shang)的(de)概念(nian)，在購(gou)買后(hou)使用(yong)同(tong)屏(ping)(ping)器(qi)(qi)達到(dao)的(de)效果(guo)(guo)和想象的(de)效果(guo)(guo)卻差強人意。在購(gou)買同(tong)屏(ping)(ping)器(qi)(qi)時，用(yong)戶要根據不(bu)同(tong)的(de)使用(yong)場景結(jie)合商家的(de)推薦，來(lai)選(xuan)購(gou)產品，這(zhe)樣可以避(bi)免選(xuan)購(gou)同(tong)屏(ping)(ping)器(qi)(qi)時出現(xian)的(de)機(ji)器(qi)(qi)不(bu)合適或(huo)是退換貨造成時間(jian)和金錢的(de)耗費(fei)。
