就画质来说，蓝光机还真打不过PC。而且你为什么说PC也是盗版？你完全可以拿PC放正版碟啊。而且说的好像碟机就不能看盗版了？现在大部分人还不是拿着破解碟机看盗版。
如果碟机画质要是那么好？那么那些顶级发烧友还要接个madvr envy(这玩意就是PC上的madvr）去接自家的碟机？还有说碟机画质之前你先把碟机设置成RGB输出，这才是真正意义上碟机处理画质。国内国外又不是没有人拿PC+MADVR跟碟机做比较，结论都是碟机画质干不过PC。
碟机厂商再怎么懂，也不可能在那垃圾硬件上有什么建树。好的算法需要更换的硬件性能的，你真以为碟机那破硬件能玩出花来？
============================================
下面是oppo的测试数据，你自己看看用的什么算法
Oppo UHD Blu-Ray player test results
------------------------------------
Tested with "Output Resoultion" set to "Source Direct".
1080p SDR Blu-Ray:
- 4:2:0 and 4:2:2 settings produce 4:2:2 output
- Auto and Auto-Safe settings produce 4:4:4 output
- with 4:2:2 output, output bitdepth is always 10/12 bit
- with 4:4:4 output, the bitdepth option is effective, with Auto producing 10/12 bit output
- the chroma channel is slightly blurred in X direction and shifted to the left (probably bilinear resampling)
- the chroma channel is upscaled from 4:2:0 to 4:2:2 using bilinear
- the chroma channel is upscaled from 4:2:2 to 4:4:4 using nearest neighbor
- with 4:4:4 8bit output, the luma channel is perfect, otherwise the most signifcant 8 bits are perfect, the other bits are a bit "weird"
4K HDR Blu-Ray 24fps:
- 4:2:0 and 4:2:2 settings produce 4:2:2 output
- Auto and Auto-Safe settings produce 4:4:4 output
- output bitdepth is always 10/12 bit
- the chroma channel is slightly blurred in X direction and shifted to the left (probably bilinear resampling)
- the chroma channel is upscaled from 4:2:0 to 4:2:2 using nearest neighbor
- the chroma channel is upscaled from 4:2:2 to 4:4:4 using nearest neighbor
- the luma channel is always perfect
4K HDR Blu-Ray 60fps:
- 4:2:0 and Auto-Safe settings produce 4:2:0 output
- 4:2:2, 4:4:4 and Auto settings produce 4:2:2 output
- output bitdepth is always 10/12 bit
- with 4:2:0 output, the chroma channel is blurred in X direction (probably bilinear resampling)
- with 4:2:2 output, the chroma channel is slightly blurred in X direction and shifted to the left (probably bilinear resampling)
- the chroma channel is upscaled from 4:2:0 to 4:2:2 using nearest neighbor
- the luma channel is always perfect
Recommendation for all users:
- 4:2:0 and 8 bit
Recommendation for Envy users with firmware 0.96.5.0 (or newer)
- Auto-Safe and 8 bit |

还有很多人说 PC 效果比蓝光机还好 我只能说他比松下都懂好莱坞 就一个 HDR 优化器就不是 PC 能碰瓷儿的
