HP LP2275w Monitor HDMI to DisplayPort possible?

Hello forum,
In the proccess of connecting my monitor HP LP2275w to computer HP Pavillion. The computer has HDMI and VGA output, the monitor has DVI and DisplayPort inputs. Recently bought a HDMI to DisplayPort adapter, in order to use the HDMI-cord, but it does not work. My computer does not "find"the monitor what so ever.
Why does the adapter not work? Do I need som sort of drive-updates?
Hopefully the forum has all the answers.

Hi,
In theory they are BOTH using digital signals therefore just straight one to one BUT practicality, this is a hit and miss business in many cases. Back to your connection: have you tried to use F4 key which tells the machine to send signals to the monitor ?
Regards.

Cinema 30" PC Monitor can use w/HDMI or DisplayPort?

Hello,
I have a 5 years old 30" Cinema Display I use as PC monitor. I want to upgrade my motherboard, and the ones I am interested in do not have DVI ports anymore, only HDMI and DisplayPort. Is it possible to adapt my display DVI cable to either of these ports and still retain 2560x1600 resolution? What do I need to do?
thanks

Yoga micro-HDMI to Displayport options

I'd like to get video from a Yoga with micro-HDMI output (female) to a monitor with (normal) DisplayPort input (female).
I've looked around and there don't seem to be many good solutions for this. Aparently HDMI to DisplayPort is not possible without an active adapter? The best I've been able to come to is:
1) Monoprice high speed micro HDMI (male) to HDMI (female)
then
2) Cable Matters HDMI (male) to DisplayPort Converter (female) - this plugs in USB for power
then
3) DisplayPort cable (male to male)
Are there any better solutions for this? That's $55+ just to get to DisplayPort. I also think the Cable matters converter will likely send at max 1080p signal.
Thank you for your input(s).

What model of monitor is it, if it is a DP++ input it should be able to use a passive adapter but will be limited to I believe up to 1920x1200.
I own a Y510p SLI, and Yoga 2 Pro

DVI, HDMI or DisplayPort

Hello,
I'm a Windows user but getting a rMBP 15". I was wondering which would be the best way to hookup an external monitor to the MacBook?
I have a high-end 27" monitor with 2560x1440 resolution (LG 27EA83) that has dual-link DVI, HDMI, and DisplayPort connectors. Since I can get a Thunderbolt DVI connector for the rMBP, but the laptop also has HDMI and DisplayPort connectors as well, which one of these would suited the best to connect the monitor to the rMBP?
Since I have no speakers, at this point I'm only focusing on display quality and don't care for audio.
Thanks.
PS: In case if I were also concerned about audio, would you recommend HDMI or DisplayPort?

Conveniently, I did order a DVD-D cable by sheer luck. I just picked the first one that had male connectors at both ends.
Now that I've got that in place, I seem to only be able to get a max resolution of 19290 x 1080 according to the options I see in the Display control panel. I've got the DVI-D cable out from the monitor and into a DVI to mini-display port adapter that connects to a Thunderbolt port on the rMPB.
I think the display is now a little sharper than when I was using the HDMI connector, but that could just be my imagination.
Time to start Googling this to see if I can sort out higher resolutions.
I had no idea there was so much variation in cable type when it came to this stuff.
Thanks for your help!
UPDATED: I finally did what should have in the first place and looked up the specs on the monitor I purchased. 1920 x 1080 is the highest resolution the monitor offers. I can live with that. It's still nearly 2x as large as my rMPB's 15" screen. [http://www.lg.com/us/monitors/lg-27EA33V-led-monitor]

Mac mini to 2 VGA monitors? IS it possible?d

I am very interested in purchasing a Mac Mini. I would like to connect it to 2 VGA monitors. Is this possible? And if yes, how do i go about getting this done.

Yep. However the quality won't be on par with digital connections like HDMI and DVI. You will need a mini Display Port to VGA adapter ( http://store.apple.com/us/product/MB572Z/A ) as well as a HDMI to VGA adapter ( http://www.amazon.com/HDMI-VGA-HD15-Male-Cable/dp/B001OLCHJ6 )

HP Elite L2201X HDMI to Displayport

Hi,Operating Systen - Windows 7 64bitI have a Lenovo Y460p laptop. It has a HDMI out on the video card. I also have an HP Elite L2201x with a DisplayPort in. I bought a Startech.com HDMI2DP which is supposed to actively convert the HDMI to DisplayPort. When I plug up both to the converter, the monitor just blinks orange. The monitor has been installed using the CD. The converter has been hooked up correctly. I don't know what the problem is. Can anothing help?

gsuren, Here are the specs for your HP Elite L2201x 21.5-inch LED Backlit LCD Monitor. According to the specs, your HP L2201x monitor has a single DisplayPort input and no other video connections. You must connect the monitor to a computer with native DisplayPort output or use an "ACTIVE HDMI-to-DisplayPort CONVERTER". From "HP ZR24W and Displayport"11-05-2012 06:53 PM - edited 11-06-2012 07:46 AM @ off1c3r, mikasa, bcody79, and others with the same DVI-D or HDMI to DisplayPort issue. The problem isn't with the monitor... it is with the way you are trying to connect your computer to the monitor. The monitor has a DVI-D input and a DisplayPort input. If your computer doesn't have native DisplayPort output, you can't use the monitor's DisplayPort input without an expensive active converter. But you say you purchased a DVI-D or HDMI to DisplayPort adapter cable??? Wrong, unless it is an active converter there is no way to go from DVI-D or HDMI at your computer to a DisplayPort monitor. The cables you have purchased are designed to go from a computer's DisplayPort output to a monitor's DVI-D or HDMI input. This is facilitated by the graphics adapter sensing an active DVI-D or HDMI connection (via adapter cable) on the DisplayPort output and switching the signaling to DVI-D or HDMI. Please read DisplayPort.org/FAQs for more information on the subject. You can also check out wiki/DisplayPort for more information as well. From DisplayPort.org; Q: I just purchased a monitor that only has a DisplayPort connection. How can I hook this up to my computer that only has VGA, DVI or HDMI?A: There is not a cost effective way to do this. The adaptors that are available only work from a DP computer to a VGA, DVI or HDMI monitor and not the other way around. If you have a desktop you can purchase a graphics card with DisplayPort. Our best advice: Before you purchase a DP only monitor make sure you have DP on your computer.

Imac 27" Intel Core 7 CPU. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware scan and all is fine. Did clean wipe from Mavrick back

Imac 27" Intel Core7 CPU 16 Gig RAM. Screen goes black and will not respond except with a push of power button. Second monitor connected via displayport continues to display fine. Apply Store did full hardware diagnostic and all is fine. Did clean wipe from Mavrick back to Mountain Lion but problem remains. Apple Store can do no more.

I did some more digging, it appears to be a backlight problem only. I can see the screen very dimly if I use a bright flashlight in a very dark room. It also seems to run ok if the brightness is turned down a LOT.
So I'm thinking this is a LED driver board issue or the display itself. I'll open it up and check the connection between the two and see if I can get any more clues. At least I can use it somewhat now by dimming the display significantly...

ATI HD2600 MacPro DVI problem with HP LP2275w monitors !!

What QT7 settings do I use to export a 1080p video for playback on iPhone4? I'm using the iPhone to playback 1080p video on 1080p monitor. Is this possible?

Does anyone know what settings I should use to export a 1080p video for playback on iPhone4? I'm hoping to use the iPhone4 to playback 1080p video on 1080p monitor. Is this possible?
I have previously saved my .mov file as Apple TV, but the quality is reduced from 1920x1080 to 960x540. I was unable to sync the higher quality file to my phone (and am worried this is the limitation of the hardware). I added this file to iTunes, added to a playlist, and sync'd to my iPhone. The playback works but the resolution is obviously a lower quality.Is it possible to keep the higher quality for playback through a 1920x1080 hd monitor? Otherwise, would I be able to sync a 1920x1080 mov file to a new iPad or other device? Thanks in advance to your answers.

No. Only the iPhone 4S, iPad3, and TV3 currently support 1080p30 content. Even then the 1080p30 playback support for your monitor may depend on how the device is connected. The iPhone 4 is limited to 720p30 playback.

Not on your current device. As previously stated, the latest generation of iPhone, iPad, and TV devices support a maximum 1080p30 playback capability but may be limited to lower resdolutions depending on your method of connection to your monitor. This information can be found on the Apple web site TechSpecs page for each respective device.

Dual screen with HDMI and DisplayPort

Hi all,
I have one question regarding my MSI GTX960.
Today I just received a DisplayPort>HDMI cable to connect my TV with HDMI.
So here is my configuration :
- GPU HDMI => Primary Screen HDMI
- GPU DisplayPort => TV HDMI
Here is my problem :
- When I boot the computer, the GPU DisplayPort takes priority over the GPU HDMI output which my primary screen is plugged in.
- Unless I unplug the HDMI cable from my TV (plugged to the DisplayPort of the GPU), it won't boot on the GPU HDMI output.
I tried all DisplayPorts to see if there was some priority but with no chance.
So I'm really disappointed as even if my TV is shut down, the computer will not boot on the GPU HDMI output and I can't access my BIOS from it (unless I unplug the DisplayPort cable before booting).
Is there a way to set default port or fix this annoying issue ?
Thanks in advance.

Thanks for your quick replies guys :D !

nope, this can't be changed its how its works
That's what I was thinking about and in fact I think it's more related to my TV as when I connect it while shut down I hear the connexion sound. It seems it is more in standby than totally shut and the GPU may have a signal from it.
Quote from: RemusM on 16-June-15, 00:43:16
The ports priority order is defined in VBIOS.
As Svet already mentioned, it cannot be changed.
Maybe having another DisplayPort for my primary screen would fix the problem ? What do you think about it ?

Samsung Monitor not receiving signal through HDMI Mini DisplayPort

I have been having issues using my Macbook Pro on an external monitor lately.
Up until a couple of days ago I was using my monitor as the primary display for my laptop and using the Bluetooth keyboard and trackpad, so my laptop has been closed. I tried to 'wake up' my mac as I usually would do but nothing happened, the monitors power light kept flashing, which is what is does when it isn't receiving a signal, so as anyone else would I investigated and found that my macbook was working the way that it normally would except it doesn't detect the external monitor at all.
I have tried changing the cable, changing the monitor from my 23" samsung display to my 42" sony tv, Restarted my mac more times that I could count and have also updated to the latest software that I possibly could.
I am going to buy a new Mini DisplayPort adapter tomorrow but I would rather just fix it with what I have if I can.
Thank you for any help that can be provided.

Check the cable does not have an air gap at either end.
Sorry ... no other ideas.

Dual Monitors with Zotac DisplayPort to Dual HDMI Adaptor?

Has anyone had the chance to try the "ZOTAC DisplayPort to Dual HDMI Adaptor" with the MacBook Pro's yet?
http://www.zotacusa.com/zotac-displayport-to-dual-hdmi-adaptor.html
I'm currently using a Mini DisplayPort to DisplayPort adapter to connect to the Zotac device, but I'm not having any luck on getting the MBP to detect the displays. I wonder if I need a specific adapter, or rather just a mini-displayport to mini-displayport?

FYI, the ZOTAC mini-displayport to Dual HDMI Adaptor doesn't quite work as advertised on my 2009 MBP 13. Under MAC OS X 10.6.8, limited to 2560 x 1024. (That's spread across the two external displays, as expected.) If you try 3840, the external screens just flicker madly. Under (bootcamp) XP, also limited to 2560. 3840 is not even presented as an option.
I know my monitors support 1920. Indeed, if I unplug either of them from the Zotac box, I can get full 1920 resolution on the other.
The reduced resolution is at least usable since I use this setup just to write code. It's frustrating though. Maybe it's due to my older laptop. I've read of this working better on newer MBPs.

Monitor Unrecognized Through DisplayPort, OK Through HDMI w/ R9 270X

I just upgraded from Sapphire AMD R7 260X to Sapphire R9 270X and am having issues with the DisplayPort. I get the wrong resolutions and unknown monitor only when connecting through DP, but everything works fine through HDMI. I am using an ASUS PB278Q 27" monitor at 1440p. The DP worked fine on the R7 260X. I was able to manually add my resultion using this xrandr guide but of course this does not persist through reboot, is quite annoying, and should not be necessary. Does this sound like a hardware bug to anyone? Should I be contacting Sapphire?

Connecting Dual Monitors: HDMI & VGA to MacBook Pro (Non-Retina)?

Whats up Apple Fam,
So i have a MacBook Pro along with a LCD TV i use as an external monitor and its connected via Mini DisplayPort to HDMI adapter.
Now, i’d like to add an additional computer monitor, the cable coming out of it will be a VGA. Hence my question; what type of adapter will i need to accomplish my goal while achieving it at the lowest price possible?
My only concern is that the Mini DisplayPort is already being used by the LCD TV. So i’m a bit unsure what to do. Any help is appreciated. Thanks !

You could purchase 2 mini displayport to DVI adapters ($30 ea) and use the 2 Thunderbolt ports. I have one external DVI monitor connected to 1 of my Thunderbolt ports. Works great!
Sorry my mistake. You said non-Retina.

Differences between adapters? (MiniDVI- VGA/HDMI and DisplayPort- VGA/HDMI)

Hello everyone
I'm going to buy a new Late 2009 Mac mini, wich for the time being will be connected to my old 17 inches Samsung LCD using VGA (I know, it's not the best solution but I can't afford buying a new monitor now) and occasionally to my Samsung FullHD LCD TV. So here are my two questions
1) What's the difference between using a Mini-DVI to VGA adapter and a Mini-DisplayPort to VGA adapter?
2) What's the difference between using a Mini-DVI to HDMI adapter and a Mini-DisplayPort to HDMI adapter? Are both HDCP compliant?
I know these may be stupid questions, but I'm a ex Windows user and the "Macverse" is new to me Thanks

One important difference between the VGA versions of the adapter is that DisplayPort does not output analog video. As such, the adapter is expensive because it has a D to A (digital to analog) converter built inside of it. It may be more prone to trouble, but it is also able to be firmware upgraded, which has already happened one time. Anyway, I would tend to choose the DVI version of the VGA adapter if for no other reason than it being cheaper.
The difference between the DVI/HDMI adapters is not so big I think, so it wouldn't matter which was used to drive an HDMI display. Either port on the back of the mini will support HDCP, and that is important with HDMI.
