大家好,
我们目前处于测试环境(已经获得批准),但我们仍然有一个奇怪的问题。 即细线内的颜色都搞砸了。 这非常值得注意。 示例1:这是在Excel 2010中进行的操作,注意红线较粗,如果我们点击那里附近的一个单元格它会自己纠正一下,但是在其他地方它会启动。 颜色也不总是应该如何,红色并不总是红色,而是橙色。 示例2:在快速滚动时,我们在Excel中获取这些黑色块,当您停止滚动时,它们会立即消失。 禁用图形卡时,不会发生这两个示例。 它们也不仅限于Office,如果我们将文件导出为PDF,它将具有相同的颜色失真。 我们的设置: Citrix XenApp 7.14(具有极高清用户体验策略) VMWare vSphere 6.5 NVIDIA Grid Tesla M10 Citrix Receiver 4.11 VDI基于Windows Server 2012 R2 以上来自于谷歌翻译 以下为原文 Hello all, We are currently in a testing environment (which has already gotten the approval), however we still have 1 weird issue. Namely the colors within thin lines are all messed up. It's pretty noticable. Example 1: This is something made within Excel 2010, notice the red line being thicker, if we click a cell near there it'll correct itself a bit, but then somewhere else it will start. Also the colors are not Always how they should be, red isn't always red but more orange. Example 2: While scrolling fast we get these black blocks in Excel, when you stop scrolling they instantly disappear. Both examples do not happen when the graphics card is disabled. They are also not limited to just Office, if we export the file to PDF it will have the same color distortion. Our setup: Citrix XenApp 7.14 (with the Very High Definition User Experience policy) VMWare vSphere 6.5 NVIDIA Grid Tesla M10 Citrix Receiver 4.11 The VDI is based on Windows Server 2012 R2 |

也许您正面临YUV_420编码问题。

嗨,
我同意mcerveny。 似乎是H264 YUV420的一个问题。 我建议将用于更改Citrix策略的用例更改为使用“活动更改区域”(又称Adaptive Display v2)。 使用XD7.17,您甚至可以使用上面的策略选择性NVENC非常好。 问候 西蒙 以上来自于谷歌翻译 以下为原文 Hi, I agree with mcerveny. Seems to be an issue with H264 YUV420. I would recommend for the use case given to change your Citrix Policy to use "active changing regions" aka Adaptive Display v2 for example. With XD7.17 you would be able to even use selective NVENC with the policy above which is pretty nice. Regards Simon |

你好,
感谢您的回复,并指出我正确的方向! 我根据mcerveny链接的第一个链接完成了以下操作: “允许视觉无损压缩” - >“启用” “视觉质量” - >“始终无损” 这之后问题就消失了。 但是,这是解决问题的正确方法吗? 我已尝试设置“活动更改区域”但此选项不可用,我可以找到的有关自适应显示v2的任何信息是默认情况下启用它如果您设置选项“使用视频编码时优先”,设置为 “对于整个屏幕”,首先出现了这个问题。 (https://www.citrix.com/blogs/2017/03/02/experience-the-future-of-work-now-with-xenapp-xendesktop-7-13/) 再次,非常感谢,因为这是我们面临的最后一个问题。 以上来自于谷歌翻译 以下为原文 Hello, Thanks for your replies and pointing me in the right direction! I've done the following per the first link mcerveny linked: “Allow visual Lossless compression” -> “Enabled” “Visual Quality” -> “Always Lossless” The issues were gone after this. However, is this the right way to fix it? I've tried setting "active changing regions" but this option is just not available, any information I can find about adaptive display v2 is that it's enabled by default if you set the option "Use video coded when preffered", which is set to "For the entire screen" which had this issue in the first place. (https://www.citrix.com/blogs/2017/03/02/experience-the-future-of-work-now-with-xenapp-xendesktop-7-13/) Once again, thanks alot, as this was the last issue we were facing. |

嗨,
你所做的是将H264编解码器从YUV420更改为YUV444。 YUV444具有色彩准确度,但您现在至少会为每个用户所需的带宽增加一倍/三倍。 因此,您应该使用这些设置。 我不是100%肯定,但是7.14中可能没有活跃的变化区域。 所以我建议首先将VDA更新为7.17。 问候 西蒙 以上来自于谷歌翻译 以下为原文 Hi, what you did is changing the H264 codec from YUV420 to YUV444. YUV444 has color accuracy but you will at least double/triple the required bandwidth per user now. Therefore you should play around with the settings. I'm not 100% sure but maybe active changing regions wasn't present in 7.14 yet. So I would recommend to update the VDA to 7.17 at first. Regards Simon |

再次感谢Simon,我们将安排更新到7.17。
以上来自于谷歌翻译 以下为原文 Thanks again Simon, we'll schedule an update to 7.17. |
