类似这种的迷你电脑，做4K播放器能不能秒杀一般的硬盘播放器。。。能到203级别么

到203级别需要2080 Ti，Chroma算法下NGC抗锯齿开到中或高，其他什么抗拖影的选项也都拉满，我这两天就在折腾这个，Kodi配合Madvr完美了，NGC开到极高2080 Ti直接卡成幻灯片

我觉得203应该做不到24fps下去拖影，Madvr这个好牛逼

洋人是这么说的：

HTPC using MadVR is far superior to what the Oppo is doing. The sharpening features of the Oppo are rubbish, they are way too heavy handed and coarse and would better suit a 1080p image, as with UHD images they just actually lessen the detail I can see, peoples faces become horrible and overcooked even on +1. MadVR's NGU is an incredible algorithm far better than anything else I have seen. Its true you need a lot of power to run the MadVR algorithms but if you set it up right it will work very well, the problem is you have SO many options that you can easily do too much.
MadVR's tone mapping is also now finally good. Its also actually properly outputting BT2020 which the Oppo tone mapping is not doing due to bugs which have still not been fixed a month later. You can actually highly customise the way it does its tone mapping too, you can use many different algorithms and even make your own curves, its also dynamic, which means it can measure each frame on a rolling average and will be able to dynamically adapt its curve to the content, this is pretty much what Dolby Vision does. There are new builds and support is far more readily available than the Oppo, even on this forum at times. HTPC and MadVR requires rips of your discs to work properly, but paired with Kodi, once you go that route, you will never turn back. I have the Panasonic UB900 as my personal unit, I have tested the Oppo 203 in my room for a week, I haven't even turned on my Panasonic in weeks, MadVR all the way. I could go on, but I have better things to do

这个人的显卡因为是1080，Madvr开不了高效果所以他觉得暂时还不如203，但是他已经看到了提高NGC的档次可以看到PC已经有逐渐接近203的趋势了：

1080 running MadVR on Win10, on 4K HDR content the Oppo is my preferred platform, the specular hightlights and shadow detail is superior, the overall dynamic range of the HTPC is lower.
DVD and BluRay is about equal to the Oppo. Basically I can see more stuff in each 4K HDR scene with the Oppo, did not notice it until I switched back to the HTPC. MadVR is running the NGU Standard Medium Quality Chroma + SuperRes upsampling with RGB 0-255 output. GTX1080 is the bottleneck, GPU load >50%, the PQ on MadVR improves and gets closer to the Oppo if I increase the processing, by the time the PQ is identical I am burning close to 90% GPU on 23.9 Hz, 59.9Hz processing is beyond the capabilities of the GTX 1080 if it is to match the Oppo. This is just with MadVR doing colorspace expansion, no luma upscaling on 4K material. Perhaps the next gen GTX1180 will do better. TV is a LG OLED 65C7, CPU is a Core i3-530, it never gets above 50% CPU as nearly all of the work is done by the GPU. Dolby Vision on UltraHD BD streams cannot be decoded by the PC, however it adds an incremental quality improvement to 4K Ultra HD blurays, I consider it a nice to have. Its main impact is on lower bitrate streams like Netflix, there the difference is almost night and day but this is outside the scope of the original question.

但是，如果你UHD碟片多的话，还是建议203，电器的操控感我觉得无敌，而且htpc现在还不支持dolbyvision，就是203现在停产被炒到太离谱的价格了，不然我也买了。索尼、松下和先锋都有$1000以上的碟机，我相信素质应该不输203多少。

要是看普通1080p资源的话，remux或者高码率的rip的话，madvr upscale选项都打开upscale上去的效果肯定是秒杀203的，看av都炸裂……

你可以去搜一个万年冷冻库的台湾人博客，关于madvr有专门的一篇内容非常多，但是是在blogspot上面挂着要番茄，内网有无转载就不清楚了

喷了

我都把1080P的压成480P看

这样省空间

很多电影一般般删了可惜留着占空间

折腾Madvr的支出比盒子、蓝光机要大多了。。。

从哪代iu开始集显能4k60hz的？

你可以统计一下，你存的片子有多少看了第二次，第三次？

那这机器得配块好显卡，这个算力现在看来是没有其他替代品，价格肯定不会比现在$1000的蓝光机低

很少有2次3次以上

有时想看了才找出来看一下

收集松鼠症严重啊

小电脑还是算了吧，各方面都不行。
htpc上高端显卡成本又上去了，而且还得考虑散热，风扇声音可不小。

我上次随手试了试，电脑直接死机了，卸载madvr也不行，连pot一起卸掉才好。

单论画质的话先锋LX500吧干掉203没问题
就是上古时代的操作很限购

我要是有环绕声音响的话，就买这个了，LX500和LX800都在我淘宝的收藏夹里呢

那噪音也跟电脑这么大就真不值了，不过作为AV High-End器材的话对于那个圈子的人来说也不算贵

为看片儿配个2080ti略奢啊……
我觉得差不多得了。

考虑一下intel自家的石英峡谷吧
