I have Benq EW277HDR (HDR10, nothing special it a false HDR).
- What free video player would you recommend me for playing x265 HDR files? Is madVR codec necessary? I was thinking of getting Pot player but I read it has malware/adware? Any other?
- For HDR do I need to activate windows HDR mode or just press HDR button on monitor (when I press it it tells me HDR: Emulated mode, If I press it in some game that support HDR it will tell me HDR: ON)? When HDR is enabled in Windows (then it automatically turn on HDR on monitor) on youtube settings I got HDR option but picture really looks washed out.
I am noob to this area so it could someone explain to me in few short steps.

I use VLC 184.108.40.206 Ventari to play UHD HDR-10 video. Note that the GPU must support HEVC hardware decoding or video playback will be too choppy to watch. To check that VLC is set to use hardware decoding so it can play 4K HEVC smoothly, go to Tools->Preferences->Input/Codecs and make sure that Hardware accelerated decoding is set to "Automatic". VLC uses tone mapping to simulate HDR if the display or the video graphic adapter's HDMI connection is not HDR capable. (My monitor is HDR capable if I use its HDMI 2.0 connection in HDR mode but not if I use its HDMI 1.4 connection. Like your monitor it doesn't support real HDR or real wide color gamut.)
If the display is HDR-10 capable and you want to use it directly instead using of VLC's tone-mapping, then you need to be running Windows 10 1709 or higher, the GPU must support HDR-10 and you must use your video graphic adapter's DisplayPort 1.4 or HDMI 2.0 connection. (DP 1.2 also works for Kaby Lake HD Graphics 630 or Coffee Lake UHD Graphics 630 with the latest Windows 10 graphics drivers installed.) I'm using Windows 10 1709. I have the Stream HDR Video setting turned on in Windows 10's Settings->Video Playback. In Windows 10's Settings->Display I have HDR10 and Advanced Color turned on and Resolution is set to 3840x2160. The display must also have HDR turned on.

I have RX 580 so GPU definitely support it (I think) but I am still on Windows 10 1703 (previous update make a big mess of my system so I reinstalled and disabled update). I will do reinstall soon to version 1903. There is HDR option on this version but many other options you mentioned I don`t see so I will try that after I reinstall system in near future.
Yesterday I tried couple of players to play HDR content, HDR was not active, I only want to test tone mapping.
- MPC - BE
- Pot player
Only Pot player has washed out picture, other was very simillar. I am leaning to MPC-BE, VLC when playing video and doing forward and backward seems a little slow, it has a short delay. Does MPC BE must have madVR installed for HDR or it is just like VLC, plug and play and set those windwos option? I don`t like madVR becasue reading some other posts it is mentioned that AMD doesn`t support madVR, that madVR was broken with Creators update or some driver update.Something new problem always rise up.
On floor below me I have some old Win7 computer connected to Samsung 4K HDR. I presumme that only way to play HDR movies in full power is to install win10 to that computer and use steps that you described?
LAVFilters and configure MPC-BE to use them. I don't know for certain if the same Windows 10 HDR settings that I used are needed for MPC-BE but I suspect that they are.
Unfortunately, I can't provide you with help for any of that based on personal experience. I don't have a computer with any recent AMD GPU. The last system of mine that had AMD graphics was built in 2009. I have been using Intel graphics for the past 5 years and I don't use madVR.

I used an old AMD Athlon II X2 250 Regor system as an HTPC until recently. It could decode HD MPEG-2 and HD H.264.AVC video using its onboard GPU for hardware-assisted decoding but that system had become very sluggish by the time I retired it. The fact that it was running Windows 7 32-bit (with the max 4GB of RAM installed) could have something to do with it but undoubtedly the old dual-core CPU was no help.
I have a few more things to add regarding VLC's support for HDR. As you know, there are multiple types of HDR. I've seen indications that VLC 3.0.1 and above supports tone mapping for both HLG and HDR10. HDR10+ and Dolby Vision are probably not supported for tone mapping. I don't think Dolby Vision is likely to be supported for a long time, if ever, because it is not an open format.
Since my monitor and my processor's iGPU are limited to HDR10 support I must rely on VLC's tone-mapping for HLG.Ignore list: hello_hello, tried, TechLord, Snoopy329
OK, first, PotPlayer is not malware, nor adware - it's just "Ad-Supported installation", so just untick the "agree" checkbox for ad while installing and the program will be ad-free, or you can use the portable version (32-bit only, yet).
Regarding "washed out picture", just press the HDR button in the main navigation panel, or change it here - right click:
Menu - Video - Pixel Shader (S) - Enable SMPTE ST 2084 HDR EOTF Correction
Menu - Video - Pixel Shader (S) - Enable SMPTE ST 2086 HDR EOTF Correction
I can't seem to find an HDR button in PotPlayer's main navigation panel. Is my version of PotPlayer too old or is it just me and my tired old eyes and brain? Maybe you could post a screenshot showing where this button is located.
The suggestions for the Pixel Shader settings, which I'm guessing apply tone-mapping, works fine. Thanks.Ignore list: hello_hello, tried, TechLord, Snoopy329
usually_quiet - the HDR button is available in your version of PotPlayer, it's available only for videos with HDR, otherwise it's missing, try to maximize window, it's in the middle, next to H/W / S/W button, only in built-in skin.
That HDR button has the same function as one of those Pixel Shader options, I think it's the first one, but I'm not sure.
HDR videos has very bad colors by default, I don't know why this option is disabled by default, so just click it once (or use that context menu option) and it will be OK.
I also have Cyberlink PowerDVD 18 Ultra, which I bought for playing UHD Blu-ray. PowerDVD 18 Ultra allows the TV/monitor to process HDR10 itself when playing video that uses it. However, it isn't free software and it can only handle HDR10 as far as I know, which makes sense due to the hardware requirements for UHD Blu-ray playback. (Intel graphics for Kaby Lake and Coffee Lake Core I processors only support HDR10.) Unfortunately, most people who come to VideoHelp for advice want free software players.Ignore list: hello_hello, tried, TechLord, Snoopy329
VLC picture looks normal without any additional settings.

My point was, nothing is perfect. Although some UHD HDR TVs and UHD Blu-ray players support both Dolby Vision and Dolby Atmos bitstreaming, the NVIDIA Shield TV could have more streaming services available, or play more types of media files, audio and video.
I know some others on this forum would disagree but I also think the NVIDIA Shield TV is the best Android TV box on the market. It probably does have additional weaknesses but I don't know what they are.Ignore list: hello_hello, tried, TechLord, Snoopy329
PotPlayer author, go to homepage, scroll down and click to "Contact us".
Every time I had problems with some files, or other users in the forum, author was able to fix it, often even in less than 1 day, but important is to send the sample file or link and describe the problem, author's English is not very good, so perhaps add 2 screenshots, from PotPlayer and from other program, where it is OK.
MPC-Hc looks quite decent with same files on 1080p tv
Does MPC-Hc being installed at same time as POtPlayer cause issues?
