KTC H27P22S 游戏显示器评测:27英寸4K IPS显示器,售价不到399美元。
中国制造商 KTC("Key to Combat")在 Geekmaxi 和亚马逊等网站上以低价提供各种(游戏)显示器。最近,我们有 27 英寸 OLED 型号今天,我们有一款配备快速 IPS 显示屏的 27 英寸游戏显示器,价格便宜得多,仅为 399 欧元。不过,IPS 面板有一点优于 OLED 机型,那就是分辨率。OLED 显示器的分辨率 "只有 "1440p,而我们今天的测试机型则达到了 3840 × 2160 像素的 4K 分辨率。我们将测试对于预算较紧的游戏玩家来说是否值得购买。
注:原文作者指的是亚马逊网站上的价格。KTC H27P22S 游戏显示器在亚马逊网站上的售价为 399 美元(可使用 50 美元优惠券代码 KTCPLAY03)。
功能和规格 - 4K IPS,HDR 400 和 160 Hz
H27P22S 采用友达的快速 IPS 面板。据说响应时间为 1 毫秒,但在显示设置中有 4 种超频预设。该面板具有 4K 分辨率,提供经典的 16:9 宽高比,最大刷新率为 160 Hz。
遗憾的是,该屏幕没有使用 MiniLED,因此没有可调光区,考虑到其仅 399 美元的低价,这也就不足为奇了。另一方面,据说 ELED 背光能让画面亮度高达 400 尼特--室内亮度足够。在色彩空间方面,只有 sRGB 是完全覆盖的,但 DCI-P3 仍达到 96%。当然,我们将在下文中测试所有制造商规格的准确性。

评语--不折不扣的 IPS 游戏机
H27P22s 不提供 OLED 或 MiniLED,也不提供 KVM 开关等简单的附加功能。另一方面,这款 27 英寸的游戏显示器仅售 399 欧元,支持 4K,并采用了较为坚固的 IPS 面板,亮度不错,响应时间也足够快,最重要的是,主观上显示效果不错。
实际上,没有什么真正值得批评的地方。亮度可以更均匀一些,左侧亮度也会下降,但我们在实际使用中并没有注意到这一点。我们也没有注意到缺少扬声器的负面影响;通常的解决方案在声音方面并不十分令人信服,但我们通常会用耳机或外置扬声器来代替。KTC 唯一希望取消的是其所有显示器上恼人的电源警告。
KTC H27P22s 是一款价格低廉的 4K IPS 游戏显示器。作为回报,它没有更多的最新技术或功能。
价格和供应情况
KTC 的游戏显示器在亚马逊等普通零售商处的售价为 399 美元。
