Fit to screen or Screen Fit is what samsung calls 1:1 pixel mapping.

not on new screens: http://www.samsung.com/hk_en/support/skp/faq/1049648

the screen resolution is 3840x2160 if you like it or not and 3840x2160 is the correct UHD resolution.

Using the HDMI audio device without Direct Sound results in just normal repeats/drops because of not exact Hz of the TV to the video, but in this mode only some Audio Formats work (DTS + HD don't work = AVR switches all the time the decoding on/off).

2. Even stranger: When starting playback in MadVR the system clock gets slow (about 10 seconds too slow per minute). Works perfectly without.
Got my card back from repair, they did a bios update (none available on internet) and all problems are gone. Card and System works fine now. Just in case someone else has strange problems like this with a new card.

Glad to hear the problems are gone, and were not caused by madVR.

@Damien, does Windows offer you to output 3840x2160? If so, try switching between 3840x2160 and 4096x2160 and check how the Windows desktop looks like. Are there black borders in either case, or some part of the desktop cut off? And which way are the fonts sharper?

Yes,it offers 3840x2160.For example if I put 3840x2160 with browser fullscreen there are black borders on the sides.If I put 4096x2160 everything works as intended and is fullscreen witn no borders.

Ok, that does sound like a native res of 4096x2160. Which is very weird, though, because it's the first time I hear of a consumer flat panel display with 4096x2160 resolution, and furthermore the Samsung website clearly states it's 3840x2160. However, often TVs use different panels from different manufacturers (unlikely for Samsung, though), depending on which size your TV is. E.g. some Sony models use an IPS screen for 42" and a PVA screen for 55" or something like that. Maybe for some reason your panel is really 4096x2160, because of the panel size you're using, but it truely is weird.

Fonts are perfectly sharp regardless of whether you send 3840x2160 or 4096x2160, right?

Everything seems to work as intended as I said.

Here is your OSD with an 4096x2160 video

now do the same with fit screen of and 3840x2160
the file you are using here isn't 3840x2160. just play a 16/9 blu ray.

without fit to screen it is cropping the image to 3840x2160.
don't you think it is strange that the TV is cropping left and right but not top and bottom without fit to screen when the actual screen size is 4096x2160?

there is no screenshot with 3840x2160 as an input signal.
and a small guess a AMD card without HDMI 2.0?

Without fit to screen it ''streches'' to 16:9 because picture size is at 16:9 standard.With fit to screen on and 16/9 blu ray I get black bars on the sides because screen is 1.90:1.

Here is a screenshot with 3840x2160 movie.http://imgur.com/a/zGiaC
You see the black bar on the side?
Here's one with 4096x2160 http://imgur.com/a/WM6oC

Card is rx470 with HDMI 2.0b support.TV and hdmi cable supports 2.0a.

yes i see them and i see that the OSD is on the correct position and i see that the player tells madVR to move the file 128 pixel to the right.

try a different player.
the second one is useless there is nothing to see because it is black.


ok because you are using an AMD card.

when switching to 3840x2160 does your TV report 3840x2160 or is it still reporting 4096x2160?

One hint is that Windows itself says 4096x2160 is "recommended". That usually means that the display's EDID block lists that resolution as its physical resolution. So right now I think it really seems to be a 4096x2160 display, as weird as it seems.

Can you maybe create another sample for me with which I could reproduce the problem? Doesn't have to be a full 4-8GB DVD, you can probably cut the movie VOB down to a small size, so that maybe just the first 2 minutes or so are playable.
madshi, I'm talking about physical discs! Also it may very well be a WinXP-only bug :S

FWIW, trying to connect my old laptop to our 4k LG TV I could only get a sharp image by putting it on 1360x768, rather than 1280x720 (or 1920x1080). On my new laptop, which has HDMI 2.0, both 1080p and 2160p work fine. I don't know if that has any relation with the strangeness Damien147 is seeing (since my old laptop didn't even support 4k output at all), but maybe the PC and the TV don't quite agree on how to interpret the signal being sent.

I don't have any XP PCs, anymore, sadly! I suppose I can dig out some DVD to test physical playback, but I think if it was really a problem, more users would have reported the problem, no? So XP seems like the most likely explanation. Have you thought about upgrading to Windows 8.1? It's a far better media playback OS compared to XP, and resource usage isn't much higher than XP, either, I think.

the fact that my the display is cropping the image left and right and is fine with 3840x2160 not. everything is done correctly at the display side : http://imgur.com/a/zGiaC the OSD is showing this clearly.

i still don't get why madVR is rendering the image to the right and that by 128p. but this has nothing todo with any display.

my RX 480 was doing the same with 4096x2160.

madVR is correctly drawing the 3840x2160 image into the 4096x2160 output mode. 4096-3840 = 256. So there must be black bars with a size of 128 pixels left and right of the active video area.
