How to Choose a DP Cable (part 2) - Vention

如何选择 DP 电缆(第 2 部分)

3. 第三个关键因素是不同版本的DP线缆。目前,市场上主要有两种DP线缆,分别是DP 1.2和DP 1.4。相比之下,DP 1.4是最新版本的DP线缆,具有更高的带宽(32.4 Gbps)和更广泛的分辨率兼容性(最高可达……)等优点。 4K@144Hz and 8K@60Hz另一方面,旧版本的DP 1.2仅支持2K 144Hz。 2K@165Hz and 4K@60Hz supp已修复。 然而,DP 1.2 和 DP 1.4 之间也存在显著的价格差距。如果您只打算购买低于 DP 1.4 标准的硬件,那么 DP 1.2 和 DP 1.4 的价格差距可能较大。 4K@60Hz or 如果您对目前的硬件配置感到满意,并且近期没有升级硬件的计划,那么DP 1.2对您来说远远超出了需求。毕竟,大多数普通硬件用户都不需要DP 1.2。 8K@60Hz or 4K@120Hz visu这些视觉效果也超越了目前大多数图形处理器的性能。然而,如果读者中有一位是追求极致刷新率和超高分辨率的重度电竞玩家,那么一款优秀的图形处理器就应该搭配一条带宽更高的线缆,例如 DP 1.4 或 HDMI 2.1。 4. 本文最后一部分将展望DP 2.0。2019年6月26日,VESA正式发布了DP 2.0接口。理论上,其有效载荷可达77.37Gbps,几乎是上一版本的三倍。此外,DP 2.0还支持USB Type-C接口。新发布的DP...

How to Choose a DP Cable(part 1) - Vention

如何选择 DP 线(第 1 部分)

在我们日常的游戏和影音使用中,随着GPU硬件和拍摄技术的飞速发展,2020年发布的PS5和Xbox Series X目前已能输出4K/120Hz的画面,而英伟达近期推出的RTX 3090显卡更是能输出8K画面。这一趋势使得老款HDMI接口的处境变得不利。例如,一台2K分辨率、165Hz刷新率的显示器,如果通过HDMI 1.4接口连接,在sRGB色域下只能以2K分辨率、75Hz刷新率显示画面。只有DP 1.4和HDMI 2.1接口才能满足这种级别的画面输出需求。 因此,我们在此提供一些选择技巧。 DP线缆 满足某人的游戏或电影需求。 首先,DP接口有两种类型。标准DP接口的大小与USB接口相仿,通常用于支持DP接口的PC显示器。更小的迷你DP接口主要设计用于笔记本电脑,包括苹果产品。这其中也包括广泛用于苹果产品的Thunderbolt接口。您可以使用标准DP线缆将任何DP显示器连接到Thunderbolt设备。因此,首要任务是检查您设备的DP接口类型。如果DP接口类型选择错误,您将无法将电脑与显示器连接。 其次,除了接口类型之外,线缆的长度和材质也需要考虑。较长的线缆可以延长传输距离,但过长的线缆会导致信号质量下降。因此,我们应该事先测量两台设备之间的距离,以免造成不必要的浪费。此外,一些DP线缆销售商可能会推荐价格昂贵的DP线缆,声称它可以提高数据传输质量。但实际上,昂贵的DP线缆并不一定能带来更好的图像质量。与上一代视频接口不同,考虑到DP采用的是分组数据传输(USB和PCI Express也采用这种传输方式),更昂贵的线缆并不能带来“更好”的图像或其他方面的提升。劣质线缆甚至会导致数据错误,严重损坏视频或音频信号。因此,确保DP线缆的材质能够满足用户日常工作环境的需求,也是我们选择DP线缆时需要考虑的重要因素。
