xbox分辨率怎么突然不支持4k了

merry christmas， everyone as you can probably tell from the tv behind me santa didn't really bring me a sony hundred inches at the nine that i've been asking for so i'm slightly disappointed now it's christmas， so i won't really say anything bad about any company so what i'm gonna do today is to try and explain the various video settings on the xbox one x and let you know my thoughts on them what they actually do and what are the recommended settings now i'm gonna use an absent projector to display the information because all these modern tvs that have tested right such as from the likes of algae from panasonic， from samsung and from sony they don't actually display all the information data of the input signal such as the big death the frame rate， the chroma， the resolution whether is in histia or not， but this absent projector i like it a lot it actually displays all these data in an information screen which is very very handy， so i'm happy using the absent projector to try and explain what all of these options do if you switch certain settings on who will the xbox one xp outputting and at the end i will give you a set of recommendations for most users and finally in this video if i have time i mean it's christmas after all， i will try and show you a specific setting on the two thousand seventeen televisions from on the top four brands in the uk， which is lg， panasonic， samsung and sony， i will show you as specific settings on these tvs that you need to actually enable before the xbox one x console will recognize your tv as hdr capable and send a necessary fork hdr signal let's go into the settings of the xbox one x go into the display and sounds that menu and go into video output now i'll set the color dev as it's default off a bead and then the color space that it's recommended value or standard for now and then we'll go into the advanced video settings i'll explain what all these options do now a lot of fifty years you should just leave take because if you are actually in the uk and european countries which is pal and if you set it to off then what will happen is that the xbox one x will be locked to her video refresh rate of sixty hurts which is undesirable if you're actually watching fifty hurts content let's say if you are using the xbox one x to route cable satellite to watch life tv on your xbox one x then it will present a lot of jaddha as you can see from this example that i'm using from the sky q box so if you actually set the xbox one x to allow for fifty herds then you can see that the judder will be removed and the whole scrolling ticker will be much smoother allow twenty four hours again is the same most of the high quality movies all film at twenty four friends per second and if you actually deselected then what will happen is that the icebox one acts will be locked to a fixed video output of sixty hurts which will present some telecitic judge in total for friends specific and movies like what you can actually see in this scene from skyfall where the slow panning shot slow zooming in shot and if you look at the information screen from this absent projector you will see that and the xbox one x is sending out a sixty her signal when what we want is to allow twenty four hurts and then what will happen is that the console will be sending out twenty four friends per second movies as twenty four friends per second which will result in a much smoother cinematic image hello hdr is suffer explanatory if you actually set it off what will happen is that the four k blur is that you play will be played back at sdr and and downgrade that to probably eight bit so switch it on again allow fork is the same as well if you actually untake it then what will happen is that the resolution output of the console will be downgraded to ten eighty p or one nine two zero times ten eighty pixels again this will also at the same time reduce the dynamic range from hdr to sdr so if you play a four k blu ray with either allow hdr or allow for k unchecked then what will happen is that the console will be playing it back as bt seven or nine sdr so i would recommend keeping the on all the time and then this is probably the most important and most confusing option in the whole advanced videos i thinks menu and i want to take some extra time to demonstrate what it actually does so let's examine the effects of allow y c c four to two on a standard ten a d p blu ray which is mastered in sdr rock seven or nine for two zero eight bit so this is a blu ray of skyfall which i really like to use as my reference this is really well mastered with lots of different scenes for me to check out various aspects of picture quality so this is a close up of daniel crick's face and what i'm going to do is to just go into the projector info screen to show you what signal we're actually receiving from the xbox one x console， and you can see there it is four k twenty four herds with a colored death of twelve pete， four two two in bt seven or nine sdr and this is with the xbox one x set to a video output of allow ycc for two now if we actually switch it off let's see what happens right if we go into the projector info screen you can see that the signal it's now sent as eight b r g b so r g b is a component to say four four four and it's still in bt seven or nine sdr， obviously and it's still in four k twenty four hurts so personally looking at this to output there's very little difference if any between eight bit four four four or rgb and twelve b for two two suddenly for ten a p s d r content， but more of the difference will come when we actually play back uh four k blue day， which is mastered in histia b t twenty twenty so let's go ahead and do that ok let's enable allow ycc for two two again and then i've put in a forky blurry of salad which in my opinion is one of the best master outraged blurry with really sharp， really crease， really clean detail with some of the highest bitteries， i've ever seen on an outraged blurry and it's a nearly four kdis well okay now if we click on the projector info screen you can see that the xbox one x console is outputting in twelve bit four two two bt twenty twenty hdr fourk at twenty four friends per second which is what we would expect this is probably the same output that will be delivered by most of the dedicator for cavalry players i said maybe some of them will be going all the way up to twelve beat four four four now let's get out from this info screen and let's go into the xbox one x menu and disable ycc four to two so if you disable it and i think i'll need to restart the disc so bearing me for a while i'll just have to quit the player and then relaunch it to replay the disc this time we allow ycc photo to disable on the console right you can see that the console for some reason is not recognizing this projector as for khdr capable， so it turns out with an arrow message and if we go into the projector info screen you can see that the microsoft xbox one x console is now only sending out eight bt seven or nine sdr in rgb video form format at four k at twenty four hurts this may be specific to this current setup maybe is the long hdmi cable run maybe it's the fact that this projector doesn't have a native eighteen gabbits， prosecca and chipset， but it shows you how important it is to actually enable the ycc photo to option because if you don't enable it and ben will requirement becomes too high because r g b is equal to four four four which is the full highest bandwidth that is required and if you're actually sending a twelve beat ten beat signal then the xbox one s console since that you know there's no compatible edit coming from the projector or the display and so it's just downgrade in the output to eight bit sdr， which is not really desirable because you really want to watch it in hdr， so you should always try and enable what you see for to two on your xbox one x console， that's the message from this short demonstration here and then we'll need to restart the application we restart the application again okay go into the projector in for screen， i can see that it is correctly sending it out at twelve beat photo to bt twenty ninety hdr， at four k at twenty four hurts which is the correct output i would expect from a decent for cavalry player and another thing that i want to actually point out is notice that the coloradoff here is twelve bit for two too even though we have actually only set the xbox one x color deaf to twenty four beats per pixel， which is eight beads so what this says to me is that the xbox one x will automatically switch and y c c for two to setting takes precedence over this video fidelity color deaf setting so maybe if you actually look at this screen here what it will do is that it is sending out eight b four to zero in b t seven or nine s t r on this particular menu screen but if you go back into the movie through the blu ray application then you should see that it will be sending out in twelve bit four to two regardless of what your color that setting was on your xbox one x console， so let's go back to the xbox one x console and send the colorado to a different one i said it ten bit if you said it ten bit what happened is that this manuscript is still at eight bit sixty hurts and if we go to 这木为 again it is still sending it out at twelve bit four to two beaty twenty ninety hdr， so yeah in a nutshell i think that there's no reason not to select it bit on your console because it will also switch to twelve bit for hdr content anyway， we know that the internal video processing of the microsoft xbox one x console is rgb based and all the processing is done in the rgb domain， but rgb inherently requires quite a high band with because it is actually full four four four so let's say if you're actually asking the xbox to send out a ten bit signal let's say a fifty hurts or sixty hurts at rgb or four four four then some hdr cables especially longer runs they wouldn't be able to transmit the data correctly resulting in either loss of signal loss of handshaking sometimes you wouldn't even be able to get a picture at all or the console things that your display is not capable of this higher bandwidth and then downgrade the resulting signal to it be sdr which is what happened in the case of this absent projector so in all cases i think you should always try and allow y c c for two two because if you actually enable y c c for two two on the xbox one x let's say for sdr content the console will be absembling the eight bit four to zero content from ten a t p blu rays to twelve b for two two which is desire because even though the data on tenty people read this is only eight bit four to zero if you actually give it a twelve beat signal again it depends on a lot of factors like your displays and how your whole video chain is set up but in general if you give a twelve beat death for the signal to be transmitted then there will be more processing headroom for the obscure the increment of sampling and things like that which will help reduce the amount of artifacts and noise in the picture again i stressed that this is not a hundred percent guarantee it depends on the display and also depends on your video chain where the twelve beat is more beneficial than i say eight beat not hand beat but in general the reason why some players like the panasonic and the opal dedicated for cable players they like to try and send out to a bit output when possible is because it gives more processing headroom to account for rounding areas so if you didn't really understand a thing i said i'll just go through the probably in my opinion the catch all set up for most displays so under video fidelity leave coloradoff at twenty four bits per pixel a bit color space is standard and then under advanced video settings just take everything but particularly important is to allow ycc for two too and then and i'll go through the specific setting you need to actually enable on various tv brands before you can actually get a proper hdr output from the xbox one x console to your display on lg is twenty sixteen and thousand seventeen sets including their all at tvs if you encounter the screen from the xbox one x console what you need to do is to summon the user menu on your lg tv go into general and then scroll all the way down to hdmi outraged deep color click on it and then you need to enable the setting on whichever hdmi part which you have connected your exposed one x console take on okay and now once you ask your xbox one x to or to detect the settings again you will see that the console will now say that your l g t v is compatible with four k ten being at even fifty hurts and sixty hurts and it supports the hdr video basically with all the takes available for all the resolution frame rate and big death on panasonics to run seventeen for ktvs usually the microsoft xbox one x will be sending all the compatible signals to the television as long as you connect the console to issue my parts one or two but in case you're not actually getting these ticks on all these frame rates and beat death and resolution then what you need to do is to go into setup and then go down into hashtmi hastiya setting and make sure that this is switched on another thing to check is that you need to go into hasty mile to setting and if you're not getting any picture whatsoever just go from either mote one and then mote to to make sure that a picture displays on screen this is to do with the hashtmi or maybe hashtcp version compatibility on the two thousand seventeen samsung tvs including kula televisions if you see the screen from your microsoft xbox one x console what you need to do is to summon the user menu go into general and then go into external device manager and then you need to enable hdmi uhd color for whichever hdmi port to which you have connected the xbox one x console after that go back into your xbox one x set up screen and then get out from here press on four ktv details again to auto detect and tv should be telling you that it supports all the four k uhd ten b fifty hundred sixty hills resolution that the xbox one x is capable of sending from the android home screen go down into settings and then go into external inputs scroll all the way down to haste in my signal format and then sell it enhanced format now notice that this only applies to haste in my pots to and tree so you need to connect your xbox one x console to to either hasty my input two or hasty my input three on your sony television for the ten bid four k usd sixty hurts fifty hurts hdr signal transmission from your xbox one x console okay i hope you have found this video useful especially if you have received a shiny new microsoft xbox one x console has a christmas present if you found this video useful， please click the like button and subscribe to the hdtv test youtube channel for more videos like this these types of comprehensive videos take an extremely long time and a lot of effort to end it and produce so i would appreciate your support now have a good
