The market started to shift a year ago, hopefully Intel's mindshare will be finally completely shattered in the next couple of months, and noone - I mean literally noone - will buy Intel for couple of years as a punishment for what they did to the PC market in the last decade due to lack of competition.
I looked around half a year ago when I put together my current rig and I was shocked that they still wanted to sell 4C4T cpus for loads of money. And I have mates who still bought that overpriced crap because they thought: if cpu then Intel.
What Intel did was stealing and they only could do that because customers allowed them to do it and they will continue this habit unless...
The following companies already voted for AMD: Sony with PS5, Google, datacenters, etc. This will be a completely different game this time.
Don't get me wrong: every corporation is the same in the long run, but today...

On the VGA front the situation is a bit different: AMD doesn't care about PC gaming for now and there are rumours that the upcoming Navi won't be the savour either.
Maybe Intel will step up in this market - and no, not for us users - and bring down the insane prices of nVidia.
We will be smarter after Computex.

(And no, I don't want to upgrade my PC - that is not just an HTPC - in the next 5-8 years , maybe buying 2-4 years old power efficient nVidia GPUs strictly from the used market)

But it's correct.

May be a stupid question.My projector is BenQ TK-800 (XPR 4K).I have been using madVR for years and always very happy with the results, and no exception with my current setup. I was just playing around with madvR settings last night, and accidentally found out that if I select BT.709/601 curve instead of pure power curve, the brightness increases, and it gives me a nice bright picture compared to what I have with pure power curve. I have selected BT 709 as my primaries/gamut and as it gives me the best picture with excellent colors. If I select BT2020, the colors become dull and undersatuarated but DCP-P3 gives me a slightly better picture.What I am asking is, under these settings, is it correct to select "BT.709/601 curve" or am I doing something wrong by selecting it? Thank you.

The BT.709/601 curve has a flat spot in the gamma curve near black which causes it to rise much faster than pure power. If your display benefits from it it is correct, however it was not designed for displays but as a way to deal with too much noise near black with early digital cameras. It is not technically correct for your projector but if you get some shadow crush it can improve the picture a lot. A custom calibration for you projector would be better, but that does require extra hardware.

This is separate from the gamut, which you should always set to whatever primaries your display uses. Your projector uses BT 709 primaries, selecting DCI-P3 or BT.2020 in madVR will give you an incorrect (and washed out) image.

I agree it's -a good thing-. However, it's NOT-important in the least for videoplayback/ madvr.

If a 4.7ghz i5 Sandybridge can CPU decode Full bitrate 4K bluray, There's flat out no reason to chase a CPU upgrade, if that budget can be put towards GPU instead.

never said someone should upgrade just if you get a new CPU get AVX2 is used everywhere.

Anyone have any suggestions for this issue?

I am not sure where to ask it, but I think it's probably a Windows or maybe NVidia thing?

I set up a HTPC for a friend, but for some reason, whenever a video opens or closes (Like starting a video in MPC-HC or then closing MP-HC itself) it causes his display to have to re-acquire it's signal.

This is pretty annoying as he has an older JVC (RS600) with a near 20-second sync time.

Now, I am completely familiar with refresh rate switching and such, but I have all of that completely disabled. I have the HTPC set for 3840x2160 23Hz RGB 12-bit (tried 8-bit as well). Refresh rate switching is disabled in madVR and disabled in MPC-HC.

Any ideas of how I can have it so that the JVC doesn't need to re-sync every time I open and close a video?

Guys, How is 980Ti's NGU performance, assuming CPU decode.

It's got all dem' Cudas

You are saying this in response to my question on the display signal re-syncing?

I have full-screen exclusive off, but I also tried it on and the behavior didn't change with respect to the display needing to re-sync the signal when the video opens and closes.

It could be because the player/renderer is set to use Full Screen Exclusive. Set it to use Full Screen Windowed and you shouldn't get the resync.

Alternatively, the desktop is set to 60hz or 50hz and the player/madVR switches to a different refresh rate when the video is played (usually 23hz).

For this reason, I have my desktop set to 23hz, that way only get a resync when playing non-23p content. However, with HDR there is a resync anyway, even if the refresh rate is the same.

If you don't want a resync ever, then you have to switch the OS to HDR and use an option to convert everything to the same refresh rate, but that's really not recommended.

I tried both exclusive full screen and full screen windowed mode. I tried every option in the rendering tab in madVR.

But even when the player opens the video in a small window in MPC-HC in the middle of the display it still happens.

I mentioned I have Windows already locked at 3840x2160 23Hz RGB 12-bit (and I tried 8-bit as well).

I have all refresh rate switching features in the video player and madVR disabled. The JVC info screen reports the exact same video signal info before and after it goes to a black syncing screen.

It's just completely stumping me as to why it's happening. And remember then it also happens when the video player is closed, but again there is no refresh rate change actually taking place.

There is also no syncing issue happening when i switch between window and full screen in the player, just when the video is started and when it's closed.


Why would HDR need to be on? I am tone-mapping HDR to SDR in madVR. The projector is seeming not actually switching anything between the desktop and video playback, but yet it always has to re-sync.

I mentioned HDR in case you wanted to use HDR passthrough in madVR. Obviously not necessary if you're using pixel shader.

No idea what's causing your issue. It certainly wasn't the case with my rs500 and isn't the case with my rs2000.

if you are using an nvidia card try NCP -> display -> adjust display colour settings -> content type reported to display and set it to something that is not auto.

Yeah, I should have posted this video:

This is exactly my issue, but unfortunately, the "fix" had no affect. I tried both desktop and video mode from the drop down.

are you sure you have selected the correct screen. only two options sounds odd for a projector.

I'm not sure what you mean by this. What 2 options do you mean and how many should there me.

This setup has only a single display even connected to the PC.

It's RTX 2070 -> Marantz 8802 -> JVC RS600.

huhn means usually you have more choices in the content type drop down, like 'photos', 'movies', 'games', etc.
I only have 'video' and 'desktop' too.

I don't have the option and no issue with displayport.
