Helix 2 4k Display 3840x2160@30Hz

Hallo, welche maximale Auflösung bietet das Helix 2 nach extern? Ich habe probiert ein DELL Monitor (P2815Q) mit der Auflösungen 3840x2160 anzusteuern. Leider bleibt der Monitor schwarz und geht in Standby sobald ich eine Auflösung > 1920x1080 wähle. Ich habe schon alle Möglichen Kombinationen durchprobiert (Tablet Dock mit HDMI, Tastaturdock mit MiniDisplayPort, Micro HDMI direkt am Tablet). Mit meinen alten T410 läuft der Monitor problemlos. Ich habe leider keine Angaben zu möglichen externen Auflösungen gefunden, nur folgendes. "The graphics chip in the Ultrabook Pro Keyboard outputs the Full HD resolution by two video lanes, but some DP monitors needs four video lanes for the Full HD resolution." Welchen DisplayPort Standard hat das Tastaturdock? Solte es <= 1.2 würde es auf jedenfall erklären warum das Tastaturdock nicht funktioniert. Welchen Standard hat der Micro HDMI Anschluss direkt im Tablet und der HDMI Anschluss im Tablet Dock?

Just an addendum to my question. The 650m supports HDMI 1.4a which in turn supports 4k at 30 Hz refresh. But the question is, has anyone tried this setup w/ a 4k display?

Lenovo Helix - Max Screen res? 4k?

Just picked myself up a 4k TV and wondering if the Helix would be able to handle outputting 4k video from DP to HDMI 2.0? Or is that asking a bit much of the older intel graphics?
Does anyone know?

MacPro with Samsung Display 4K

Hey there, i want to buy a new MacPro (Late2013), with two AMD FirePro D500 GPUs - and a Samsung U28D590D.
(Samsung 4K Display 3840x2160 resolution). Are there some issues with this display and the graphic cards - or will it work fine ?
Does anybody has some experience with this display ?
Hope you can help me .

Hey man, just curious if you ever completed that set up. Reason i ask, is because I have the same set up, and I am trying to find the best settings for the monitor, and also the mac pro preferences to use.
I was using a Thunderbolt Display, and am hoping I didn't make a mistake jumping on the "4K" Bandwagon

Problems with 4K 60z in Mini DP

Hi~
I have a Mac mini (Late 2014,Intel iris 5100 Graphics) which supports display in 4K, and a 4K display.
But unfortunately it is at 3840x2160 30hz with mini displayport 1.2 plugged in.
My MacBook Pro (Retina, Late 2013) can work at 3840x2160 60hz with MST enabled as the Apple Support Document mentioned(Using 4K displays and Ultra HD TVs with Mac computers - Apple Support).
So I search the Internet and I found that there's no hardware limitation in iris 5100, which means iris 5100 can enable MST and output at 60hz.
Is there a way to force enable MST on Macs with iris 5100 Graphics?

Not that I know of. Apple only say 4K at 30Hz.

Max 3200x1800 resolution on 4k monitor??

I got my Asus PB287Q 4k monitor yesterday and started using it with my Mac Pro (Late 2013). A few issues arise:
If used alone, I get a max resolution of 3200x1800 @ 30Hz.
If I switch to DP1.2 in the monitor preferences, I get max 3840x2160 @ 60Hz, but then I get artefacts on the right hand side of the screen (apparently this is an Apple problem and is going to be resolved in 10.10), but effectively is useless
The only way to get max resolution of 3840x2160 @ 30Hz is to plug in an additional Full HD monitor via HDMI (I am not joking!)
There is no startup screen on the Asus (not really bothered by this)
What I would like to do is use the screen at max resolution simply on its own. 30Hz is absolutely fine for what I am currently doing.
I appreciate your help.

Good thought. I tested it with the three different buses, same result.
Funny enough, just looked at my 'About This Mac':
It shows the Aus as having 6400x3600 resolution, which is not correct.
Here is the screenshot of my Display Prefs:
Both displays are driven from a D700 in slot 2:
Also, when the screen comes back online (after sleeping, etc.) I might have the 3200x1800 resolution back up. I am using a DP 1.2 cable sourced from Amazon.com.

Any pointers would be great thanks.

Hello JHyde01,
Thanks for using Apple Support Communities.
If you want to use a 4K display with your Mac, the displays are limited to a Maximum of 50Hz on one specific model as shown below.
You can use 4K displays and Ultra HD TVs at the following resolutions and refresh rates via the built-in HDMI port.
3840 x 2160 at 30 Hz refresh rate
4096 x 2160 at 24 Hz refresh rate (mirroring is not supported at this resolution)
With OS X Mavericks v10.9.3 or later, the following DisplayPort displays are supported at their default using single-stream transport (SST) at 30Hz.
Sharp PN-K321
ASUS PQ321Q
Dell UP2414Q
Dell UP3214Q
Panasonic TC-L65WT600
With OS X Yosemite, you can use all of the above displays as well as the following:
LG 31MU97 4K display (at 30Hz or 50Hz)
Other Mac models do support MST displays at 60Hz as shown below.
MacBook Pro (Retina, 15-inch, Late 2013, Mac Pro (Late 2013), and iMac (Retina 5K, 27-inch, Late 2014) computers also support multi-stream transport (MST) displays at 60 Hz. If you use a 60Hz MST display with the MacBook Pro (Retina, 15-inch, Late 2013) or iMac (Retina 5K, 27-inch, Late 2014), only one additional Thunderbolt display can be supported.

Where do I find the UI Scaling option in Photoshop CC 2014?

I have a Companion Cintiq running Win 8.1..I am a new PS user..After searching for an answer to the tiny and unreadable text and icons on my screen and not being able to enlarge them (no, the display fix inside Windows doesn't do it), I basically found there is no answer at all from Adobe on helping us actually see the software there selling us..So in reality, I'm supposed to suck it up and be happy with what I have?..Can anybody fill me in on an upcoming fix or if there is one and I just missed it?

If you have the newer Cintiq companion 2 CC 2014 has a 2x UI preference which may work quite well the at 1/2 resolution the display 1440 height become 720 so the single column tools bar will just not fit on the display however it will fit in two column mode. All icons, dialog, menu bars. Pallets etc will be scaled up ins size 2x each pixel is displayed using 4 pixels to double size what is displayed.   However the image area is not scaled to 1/2 resolution so when you view image actual pixels 100% zoom you see your image at your display high resolution.
Older companions displays were only 1920x1080 pixels have a higher the 96ppi   but not a resolution as high as the newer model. If the UI is to small for you you need to force Windows scaling you can have windows scale the display 1.25x or 1.5x Photoshop UI should fit however the image Photoshop displays will also be scaled by windows. 1.25 and 1.5 X are not even factor of resolution so some round artifacts. Scaling the display also defeat high resolution yor effect have a lower resolution display.
2x UI is an even factor of resolution there is no rounding scaling but requires a display with 2048 x 1536 for 2x makes the ui be 1024x768 and meets Photoshop required min display size. The work will on 4K displays 3840x2160 becomes a UI the is 1K 1920x1080.
It was your choice to buy the display you did Wacom did not hide its size and number of pixels. OS and Application had always run on displays the had a ppi around 96ppi. So every was programed to work on 96 ppi displays.   When you reduce pixel size to cram in more detail into the same area you need to add pixels to UI components to display the the size the displayed on 96ppi displays.   OS and Applications were not designed with a feature like the. The problem became evident is 2001 when IBM marketed the 204ppi 4k display its t220. That display was very expensive so it was not widely used only used for special needs. Only now are high resolution display affordable so now the problem is beeing addressed. But is will take time OS and Applications will need updating.

Please help@

Windows will scale applications display or windows will not scale application display depending on how the application is coded. Photoshop is coded in a way that its display is not scaled by windows. Photoshop knows about your displays high pixel count not its resolution so it uses its pixels however it does not scale its UI to make it usable on your display. Other application let Windows scale their display output.   For example Microsoft default for is Surface Pro 3, 216 ppi display is to scale applications display up 150% so the surface pro 3 display which has 2160x1440 pixels a 216 ppi resolution look like at display with the user is using with 1440x960 pixels. The Application works like the display is 1440x960 and Windows scale those pixels to the displays using the displays 2160x1440 pixels the effectively changing it resolution to 144ppi rather than the actual 216ppi.
The reg update and external manifest file effectively tells photoshop its working on such a size display display some number of pixel wide and some number photoshop uses that as the display size in turn Windows scale those pixels to use the displays 2160x1440 pixels efector lowing its 216ppi resolution. Photoshop CC 2014 2X UI would be like using windows 200% option applications would be shown the are working on a display 1080x720 instead of the Surface Pro 3 2160x1440. Note that 1080x720 does not meet PS requirement of 1024x768. Photoshop UI would not fit on the Surface Pro 3 display..
Since you have a 4k display if you have CC 2014 you can use its 2x UI effectively Photoshop will be running on a 1920x1080 display and have half the resolution of you 4K display 3840x2160 pixels four native pixels are use as a single pixel.   1920x1080 pixels exceed PS requirement.

Reading images efficiently

Hi all,
I have a question that I want to ask before I start building my next application. I have a camera which sends me images to a specified folder and with specified name format. At the moment the name is taken as a data in the following format:
0:yyyy-MM-dd_hh-mm-ss.fffffff.bmp
The name format can be changed. What I need to do is take every image from this camera in the correct order, read it from a specified path, and show it in LabView. The camera gives images with 30fps frame rate. Finally there are two questions:
- what is the most efficient way to read and show these files one after another as fast as possible
- what is the simplest way to iterate through names? Because I can change the name format maybe there is some other more 'LabView friendly' format of name I could use?
I appreciate any help.
Solved!
Go to Solution.

The format for the name of images doesn't change anything to your problem, LabVIEW can interpret the yyyy-MM-dd_hh-mm-ss.fffffff.bmp format so no issue here.
Reading images from disk, images that were save to disk by the camera, that doesn't sounds like the best idea to me ; it will probably work but not sure you will be able to display at 30Hz live (that will depend a lot on the size of your images). Maybe you could just get LabVIEW to load and display the most recent images saved at the rate you can. but that will use a lot of disk access.
What is you camera? What's the size and bit depth of you images?
If you have VDM (Vision Development Module) you can acquire images from your camera, and then you wouldn't have to get the camera to save to disk and your LabVIEW app to read from disk...
Hope this helps

Games in intel hd graphics 5000

Can anyone tell me what games we can play with a jntel hd graphics 5000?????like can we play far cry 3 or watch dogs etc????????

I have found this in the Intel website:
DisplayPort* 1.2 / eDP*
H-Processors: 3840 x 2160@60Hz
(Ultra-HD)
U-Processors: 3200 x 2000
@60 Hz, 3840x2160@30Hz
Y-Processors: 2560 x 1600
@ 60 Hz
HDMI* 4096 x 2304, 3840x2160 @ 24Hz / 24bpp
DVI 1920 x 1200 @ 60Hz
I doubt that Apple disables the maximum GPU resolution, and I don't think that a firmware update will be released for that. Instead, as you can see, it looks like Y-processors don't support a resolution higher than 2560x1600, so it's possible that the MacBook Air comes with one of those processors

Newest Mac Pro: Displays How will 4K be displayed? : 4K 3840x2160 UHD 4096x2550 Where as: 27-inch Apple Thunderbolt Display=2660x1440

How will 4K be displayed? :
4K 3840x2160
UHD 4096x2550
Where as:
27-inch Apple Thunderbolt Display=2660x1440

4k is the generic term for resolutions that have a horizontal number of pixels around 4000. The two most common resolutions are Ultra Hi-Def (UHD) and Cinema 4K (C4K). The first is 3840x2160 and is exactly four times the resolution of "Full HD", or 1080p. The second is 4096x2160 and is one of the "standard" resolutions used in digital cinema projection.
The HDMI 1.4 standard supports both of these, but only at certain refresh rates. UHD, being the consumer version, is supported at 24Hz, 25Hz, and 30Hz; C4K is only defined for 24Hz since most of the material is going to be film-sourced. (This implies that 25/30Hz will include TV material at half their original rates of 50/60Hz.) Over HDMI, all four of these timing formats run at the same clock rate (297MHz, ignoring the fractional versions). This is the highest clock used in this version of HDMI, although the standard allows up to 340MHz. (There may be PC timing formats between 297-340...)
Using generic terms, we call these modes "UHD30" to imply resolution and refresh rate, and if a TV supports UHD30 it will always support UHD24 (although it is not a rule, merely a reflection of reality). A TV can only support C4K24 in 1.4, but it doesn't have to. There are many TVs that will support UHD24 or UHD24-30, but not C4K at all. So the practical limit of HDMI 1.4 is "up to 4k30."
HDMI 2.0, which the Mac Pro does not have [yet], provides dot clocks up to 600MHz (although above 340MHz, they are all divided by 4) and allows "up to 4k60" for pixel encodings of RGB444, YCC444, and YCC422. The new standard also allows 4k50/60 to use YCC420, which sacrifices some color information (known as 'uses chroma subsampling') but allows the data to be transferred at the same rate as 4k30. While "fine" for video--since it was probably delivered over BD/DVD or streaming at YCC420 to begin with--it is not fine for you computer's output.
I just got a 4k TV because I was tired of my dual 1920x1200 DisplayPort monitors after coming from the original 30" Cinema display of 2560x1600. Specifically, I used to enjoy >1080 pixels tall. But here's the problem with the 4k TV: while it has HDMI 2.0 inputs, the MacPro has only HDMI 1.4 so the output is limited to "up to 4k30". Moving the mouse is laggy and not smooth as it would be if the display were 60Hz. Furthermore, the MacPro is not offering me a choice between UHD or C4K--both of which the TV supports--and is instead defaulting to the largest resolution of C4K. This means the refresh is only 24Hz. And that's why I'm in the forums today--to see if there's a way to get my output to be UHD, but at 30Hz.
In a couple months, several companies will be selling DP-to-HDMI2 dongles that will support 4k60. So I am holding my breath until then.
Now, to specifically and accurately answer your question: Out the current MacPro's HDMI 1.4 port, you will get the highest resolution your TV (called the Sink) will support. If your TV has C4K24, then that is what will show up. If your TV does NOT have that, but has UHD24-30, you SHOULD get UHD30. If your TV ONLY has UHD24, then that's what you will get. If you get a TV, the chances are really, really good that the panel will have 3840 pixels across and 2160 lines down. In this case, you want the Mac to output that resolution and put the TV into pixel-for-pixel mode so every input datum is mapped to a single display element. Since most displays overscan, the Full mode will expand the incoming data from 2-5% which can eliminated the crispness (and also cut off the extremes of the Desktop). Also, if you are outputting C4K (like I am) AND you have switched to P4P mode, the horizontal dimension is shrunk by 6.6%.
If any of this is unclear, just reply. But I will say that this 40" TV is really useful, and once it is running at 60Hz...bellisima!

Helix - Two external displays + laptop display

I would like to extend my desktop to two external displays (1080p) in addition to the Helix screen. Of course, we only have one mini-displayport on the Helix. I don't have displayport-enabled monitors which can daisy-chain. Which of these options would you guys recommend?
1. Using the Lenovo or Startech Displayport Splitter, which will make the two external displays look like one giant display to the computer.
2. Using wi-di for one monitor while using the physical mini-displayport for the other. Will this work? If so, any recommendations for a a wi-di adapter for a monitor?
I don't want to use a USB dock / monitor extension, since I don't want to be using CPU power to drive the displays. Are there any other options I am missing? If it matters, the internal display of the Helix uses a displayport-type adapter.
Thanks!

Trying to figure out how many displays that the Thinkpad Helix can drive via the GPU (independent extended mode, meaning each display is NOT a mirror/clone of another)
Tried to look at the manual/search, can't find it.
I'm sure you can do at least 2 connected displays, like any laptop sold within the past 10 years
1) internal display (1080p)
2) via Minidisplayport (1440p-1660p?)
How about 3 displays
3) via WiDi?
4) via Displayport chaining?
How about max resolutions? (all my displays are below 1080/1200p for now, but for future reference)
(not looking for the USB driven monitors, because
1) a lot of them tend to be cpu-intensive instead of being driven by the GPU
2) I want to be able to "dock" the helix with my existing large displays
