有關MadVR 130版HDR功能
又打了一篇新的教學 修正之前存在的某些bughttps://tieba.baidu.com/p/7343810577
由於貼吧沒有編輯功能,我將一樓的錯誤補在二樓修正

"output video in HDR format" seems to be the best choice for HDR TVs (better than the tone mapping of the TV alone and way better than "SDR" conversion)
作者回复
I don't feel comfortable with this statement, because it's very generic. The way you wrote it, it seems to be a definite recommendation for all TVs. Giving such a recommendation is IMHO a very bad idea, unless you really had a chance to test TVs of all major CE companies, ideally even from different TV generations. The tone mapping firmware of those TVs varies *WILDLY*. As a result, whatever works for your TV, could be totally bad for another TV. It's impossible to predict, IMHO, without having tested it.
When that option is activated, madVR switches the GPU into "HDR" mode, which means the GPU informs the display that the data coming is in HDR (PQ transfer function). Furthermore, of course in this case madVR also outputs a PQ transfer function signal instead of gamma. Activating this option may be useful for some OLED users because some OLED displays switch into a different (brighter) driving scheme, when receiving an HDR signal, compared to SDR. However, activating this option will usually also mean that the display will apply its own tone mapping algorithm on the signal, which is not good for image quality. So my recommendation would be to turn it off - unless you have an OLED display. With an OLED display, you can try this option on vs off and use what looks better to your eyes.
所以说拿电视机当hdr显示器要么直通要么把电视机的后处理全部关闭。。。
思路就是要么madvr全权处理，要么电视机全部处理...两边都映射和调色太奇怪了 好在這幾天終於解惑 呵呵，之前都亂搞教程 所以说你用着HDR的设备一直在看着转换SDR? 本帖最后由 jp4bgmm 于 2021-5-11 21:59 编辑

之前有跟你討論過,所以out put當然當有開,還有討論到二次映射問題
不過今天看到既然作者都這樣說了,從今天開始非oled電視都直接轉sdr看了不是嗎<不勾out put的話>?

HDR LCD你也转SDR?这完全没必要吧.

所以電腦螢幕可以繼續勾選囉
