HP Envy 14 - mini Displayport to 30 inch monitor

So, I have a Dell 3007FPW-HC that is dual link DVI and 2560x1600. According to the specs I found, the 5650 Mobility should be able to support that resolution on the Displayport output.

I picked up an active adapter (Accell) that converts a mini Displayport to a dual link DVI. I hooked it all up and no dice. The ATI drivers do not detect the monitor. At first, I thought it was the adapter being a dud so I took it into work and tried it with a Mac and a Mac Cinema Display which worked perfectly. It seems there is some limitation on the driver or port. I also tried it to a single link DVI with the same results (1920x1200).

Has anyone else tried to drive an external DVI based monitor with the mini Displayport with an adapter? It would be nice to get this working.

 

you may have to use some sorta hdmi-dvi adapter instead.


not sure. people were having a couple problems with the mini display port

 

Interesting. I had seen some using the displayport adapters on the Envy 17. I wonder if this is an Envy 14 specific issue?

I already have an HDMI to DVI adapter I am using today. Guess I will have to use the 24 inch monitor instead of the 30. Dang, it would have been nice to leverage all that space. I used that on the 30 inch but, of course, with ony half the bandwidth, the max resolution is 1280x800. Using the desktop is like playing with Duplo Legos.

I am going to look into this a little more. It's going to bug me.

EDIT: Just looked on the Dell site. The connector is certified to work with the Dell 3007FPW so it looks to be something with the laptop.

 

I have a similar issue.

I have a mini display port to VGA that I bought with my MacBook Pro. When I plug it into the E14, it doesn't even recognize that the monitor is connected.

Could there possibly be a set of mini display port adapters that only work with Mac products?

I called HP. The rep's answer was to use the HDMI since I already noted that worked. Problem is, the HDMI connection type is A (single link) and would not support dual link (as far as I can tell). They noted that 1.3 can support up to 2560x1600. The specs of the 5650 not 1920x1200 max but that is in deep color mode (48 bit). I think it is a cable limitation, however. Have to look into that more.

Now, for some tests. Mac to Mac monitor with mDP adapter - works. Mac to Dell monitor wth adapter - works. HP to Mac -does not work. HP to Dell monitor - does not work. I wonder if a BIOS update is needed.

 

I'm having problems connecting to my tv through HDMI. It says its outputting 1080p but it only fills around 90% of the screen. Setting the tv to 'just scan' or 1:1 doesn't fix it, which is odd because my old computer that used DVI->HDMI displays just fine and it fills the whole screen.

Also tried messing with settings in display properties and CCC but no luck so far...

 

Some facts regarding the video outputs.

HDMI - It is a 1.3a setup which had increased bandwidth to support up to 2560x1600 resolution. There is no dual link DVI adapter. It will only work on a single channel.

mDP - supports up to 2560x1600. This "should" work with the adapter but the ATI card does not detect the monitor. You need an active connector (USB powered). Alternately, you can get a mDP to VGA adapter that supports up to 2048x1536 (not on the 30 inch).

You will always need an active mDP adapter for any resolution above 1920x1200. Best bet, stick with a 24 inch monitor or get a 30 inch with HDMI or mDP already built in.

 

I get the same thing on two different TVs through HDMI. It appears that a border is added and the image rescaled to fit in the smaller area. I guess this is to ensure that the full image is visible on a broad range of devices??? Interestingly it doesn't add the border when connected to a PC monitor. Has anyone worked out how to turn this border off?

 

Ok I tryed everything out here...
The following monitors where used; the samsung is mine, eizo of my parents, the apple is my roommates, iiyama is from my uni:

• samsung syncmaster 2494hs
• apple cinema display 30"
• eizo s2433we
• iiyama prolite E2210HDS-B1

These are my conclusions:

mDP -> to anything expect dp will not work.

• mDP->hdmi: monitor & resolution is recognised but not video
• mDP->dvi: monitor & resolution is recognised but not video (this was with a passive adapter)
• mDP->vga: monitor & resolution is recognised but not video
• mDP -> DP: video and everything works well.

I won't spend 100+ euro's on an active mDP -> DVI adapter unless I get a side job next to my uni ...(student's e not one of the richest )

Anywho ... hope this helps.
Though hdmi everything works fine...
I got video though a:

• hdmi - dvi kabel
• hdmi - dvi adapter - vga adapter
• hdmi - hdmi (sounds works with this one aswell )

 

Thanks for the tests.

mDP > Apple Dual-link DVI (active) with dual-link DVI-D cable: monitor & resolution NOT recognised

This is Envy 14 to Samsung 2494HM

Called HP and they offered to change the motherboard since mDP doesn't work. But this doesn't seem to be the fix at all.

 

Have you guys had any success with miniDP to VGA adapters? I bought the Apple one and it doesn't work. According to someone on this forum, it only works with the Macs.

I have not tried to get a generic one yet, but wanted to see if you guys had any luck with anything. I really do not want to buy an HDMI to VGA converter.

I bought this laptop, in part, to help me with doing presentations and now I can't even hook it up to a projector!

 

I purchased some mdp to vga and mdp to DVI adaptors from amazon. I have had no problem connecting them to my dell 17in sips monitor from 2002. I tried both the vga and dvi, no problems here. bios F.05.

 

in CCC go to
1. Desktops and Displays
2.Click on the little black trangle in the top left of the SMALL (repeat SMALL) display icon at the bottom of the window
3. Select Configure
4. Click on the 'Scaling Options' Tab
5. move slider til the image fits the screen

 

UPDATE: It works with the Moshi mDP to HDMI.

Mine is connected with
Moshi mDP to HDMI and HDMI to DVI-D. Works fantastic.

Dual 24" monitor fun with the Envy 14 now!

 

Has anyone tried the mDP to VGA adapter from Monoprice? They usually make good stuff, reliable, I've never had any problems with them, but it seems that the Envy is quite picky about what it will accept

 

yes i did. the screen flickers like hell. the max refresh rate i can set the vga monitor to is 75Hz (originally 60) and it still flickers.

the first one flickered, so they sent me another one and told me to return the first one

the second one still flickers. bull crap.

 

You guys might want to try an adapter that has a USB plug for power. Flickering on an active adapter is a pretty good sign it does not have enough power.

 

I tried the Accell USB powered adaptor, but there was no joy.

Is there any solution known to work with this? Cost isn't really an issue. Otherwise I may have to sell my monitor...

 

Hi guys,

Sorry TS for hijacking. Just a small question. I was wondering if this cable will be functional if i connected it from my Envy 14's mini displayport to a projector whic uses VGA?

Thanks in advance!

Regards.

 

Just bought a cheap Mini-DP to DVI passive adaptor in Korea.
Connected to an old 17" VX700 monitor (1280 x 1024).
Monitor detected, but no video.

Was probably worth a shot. =/

I'll try on a Samsung monitor. See if anything appears.

 

? Is there any definitive answer for this problem? I just bought a mDP -> VGA from the Apple store. You know I don't like wasting $30...I hope they will take it back...Because it doesn't work. Do I have to get a more expensive HDMI to VGA or DVI converter? I have a nice 22" ViewSonic LED 1080p monitor. It actually has TWO ports both a DVI and a VGA. Since the monitor shipped with a VGA cord I got a mDP -> VGA and figured sure great it'd work...Nope.

Should I go and exchange for a mDP -> DVI dongle and then buy a DVI cord? For what? Only for that not to work either? Then since the Apple store didn't have any corded mDP -> DVI nor cables, I'd be left with running all over town trying to return things that didn't work when they were freaking supposed to. Why even put a mini display port on a laptop if it isn't going to work? ?! I love my ENVY 14, but this is absolutely retarded. I would've taken an extra USB over this piece of junk clearly broken mini display port. It's a cord, a dongle, whatever. It shouldn't matter where it comes from. Why do I have to go to the moon to find something that works? Even if I did, has ANYONE PERIOD been able to get the mini display port to work? Or only with a monitor that has a mini/display port? Again...leaving one to go to the moon to find that. It's like that HP mini (i have one sadly) that has that stupid proprietary port for external monitors. Who was in charge of making these decisions? Fire them. Seriously, how can anyone think it's a good idea?

 

check your drivers. with the ATI driver 10.12 at least, the apple mini-dp to vga works flawlessly for me - no tweaking required at all.

 

I recently tried connecting my envy to a 42" TV and it didnt detect even when i tried to switch. The moment my fren brought his mac over to try, it worked even without having to switch displays or anything. Makes my envy look like a retard which makes me mad

 

i was worried that i wouldn't be able to connect to the projector at work - so i even put the presentation on a flash drive just in case.

turns out it worked right away using the mbp's mini dp to vga adapter, i can select it to be either extended desktop or duplicate, as well as the resolutions. it even allows me to have 2 different resolutions for the two screens.

make sure you have the ATI graphics active (i used i7, so that's the only one available to me), and update your graphics driver to the current release. other than that i don't know what to tell you? use an hdmi -> vga adapter instead?

 

Thanks a lot man! Yeah I guess the problem is that I had Intel GPU on instead of the ATI. The moment i switched to ATI the projector detected the input. However, this still doesnt work for the connection mDP to HDMI TV. Anyone has any solutions to this?

Thanks in advance guys!

 

if there's anyone out there wondering, 30" dual-link dvi to minidisplayport still doesn't work with this machine. the last word from HP was that the next bios update was going to fix it, but an update [F.23] was released and had no effect.

 

I'm installing drivers directly from ATI, perhaps HP had dated drivers on their web site. I'm not too happy with HP's software and driver support (I have another issue with possibly their 3D drive backup that's causing bluescreen errors on sleep). So we'll see....

Before reading the reply about drivers, I got an HDMI to DVI-D cable for like $15. Works perfectly and is cheaper than the Apple adapter. So something to consider for people too. Of course I'm also lucky in that my monitor has DVI and VGA.

 

What resolution are you running at? My 30" has DVI, and it only displays 1280 x 800 through the HDMI port. AFAIK, a dual link DVI - Dual link HDMI does not exist yet.

Has anyone been able to drive a 30" monitor at native res with the newer ATI drivers? Last time I checked I only had the old HP drivers and it didn't work with the Accell miniDP - dual link DVI powered adaptor. As a consequence I sent the adaptor back to the wholesaler.

Edit - actually HDMI - Dual Link DVI cables do exist and I have found a supplier here in Perth. I have ordered a cable and will pick it up tonight, I will let everyone know how I go...

 

I did some more research into the HDMI @ 2560 x 1600 and I don't think its going to work. HDMI has electrical compatibility with DVI but only at HDMI ver. 1.2 data rates. HDMI ver. 1.3 is the first revision to allow 2560 x 1600 resolutions, so it would seem that HDMI - DVI is limited to 1920 x 1200.

Also, from the ATI website the specs for the Mobility HD 5650 state that it is limited to 1920 x 1200 from the HDMI output.

I think I'm out of luck with this one...

 

HDMI 1.3 has higher bandwidth (to support >1920x1200) by increasing the frequency, but as you said this doesn't help with HDMI->DL-DVI conversion since the DVI monitor can't understand this kind of signal.

I ended up returning Envy 14 because of this and for now I'm using a laptop with an expresscard->pci-e adapter to attach my screen to a desktop video card.

 

So I'm running Catalyst 10.12 and while on ATI graphics, my mDP -> VGA still doesn't work.

Anyone have any other ideas?

 

I have yet to get one to work either. I tried both the Mac adapter as well as an Accell, and neither will give a signal to either my 1920x1200 Lenovo 22" monitor, nor to an older projector. An Accell mDP->DVI works fine, though.

 

Just want to throw in another model that work with the envy.
I used the moshi mDP->VGA cable, and tried it on a few monitor
and projectors and it works fine..

 

I'm just wondering why we are facing so many troubles with the mDP ports and HDMIs on the Envys..

My friend's Mac plugs right into a 51" HDTV via mDP-HDMI no problems at all and it even automatically detects. I can't even plug a HDMI-HDMI to that same TV.. Damn

 

People are having trouble with the HDMI? News to me...

ArchEnemy, you were running on ATI graphics at the time, right? Even if you weren't, my Envy prompts me to switch from Intel to ATI if I do plug an HDMI in while on Intel. I get nothing if I plug anything into my mDP, no matter what I'm running on.

 

Yup I was on ATI. My mDP port is officially useless to connect to TVs..

 

Should mDP to DVI work for any monitor under 30" without the dual link cable? I have a single cable that's mDP on one side and DVI on the other. Seems like it worked on my monitor for a while but just stopped working recently.

 

Hmm, have people tried a 2-step conversion instead? Mini to full-size, and then full size DisplayPort to DVI or VGA.

I've used the Sapphire DP-to-VGA on a desktop HD5570, and it worked perfectly; so I'd hope that'd work for laptops as well.

 

I've concluded that on the Envy 14 (NOT the Envy 17 or other sizes), mDP (mini display port) to VGA does not work and cannot currently be made to work (although there seem to be some fluky exceptions, see below). NOT the other Envy models, however. This is what the competent-sounding technician at HP says, and it seems to square with my experience. MDP to VGA just doesn't work on the Envy 14. It is a 'known issue' and it has been for months and months. The technician told me that a fix might come with a BIOS update, and that May is a popular month to release those. To be fair, though, he admitted he was mostly guessing.

I have my doubts that it's a BIOS problem for the simple reason that I would have expected them to fix it by now. Also because people complain that the mDP can't always output to HDMI or DVI reliably either.

PS I am NOT talking about HDMI to VGA--only mDP to VGA. HDMI to VGA seems to be a workaround (I haven't tried it yet, though).

It is true that a small number of people have got mDP to VGA to work. e.g., see http://forum.notebookreview.com/hp-envy-hdx/554145-working-mini-displayport-mdp-vga-adapter.html ---But as I said in that thread, I found the exact same adapter model at Home Depot today and it didn't work for me. And as far as I can tell, I have the most recent BIOS (f.23) and graphics drivers (8.771.1.0). (Please correct me if I am wrong about the driver versions--it would make me really happy if that fixed it!)

There is a thread discussing the mDP to VGA problem on the HP website:
Cannot get mDP to DL DVI working on Envy 14 to use a 30 inch... - HP Support Forum

 

Hi Guys,

I'm having trouble getting a mini displayport to DVI adapter to work on my Envy 14.

When I plug it in the envy 14 it detects the monitor name and max res but I get no video - just a black screen.

I have an HDMI to DVI adapter which works, but I'm trying to run two external monitors at the same time so need the mDp > DVI to work as well.

Interestingly, if the mDp adapter is plugged in, both that and the HDMI>DVI adapter don't show video on the screens (just black on both).

So, basically my question is... is there hope for my mDp to work via DVI? Is it worth me trying other mDp>DVI adpaters? Can anyone recommend one in the UK?

The mDp>DVI adapter I have already is this one: Gold Mini Display Port to DVI adapter for MacBook @UK on eBay (end time 24-Mar-11 15:13:17 GMT)

Thanks for any advice/help with this.

Mike

 

This is news to me I use my mDP to VGA port every day at work. I bought a cheap mDP to VGA adapter at Bestbuy and have had no problems. I also use it for overhead projectors.

Right after I bought my Envy 14 I had a bad graphics driver update. Was about to pack it up I did a complete system restore and then a new update (two months ago) Since then everything works great.

 

Any update on this?

I have the Envy 14 with a Dell 3007 30inch and I can't get the resolution to go any higher than the standard 1280x800. Right now I am trying the HDMI to DVI-D. It is huge but too low of a resolution at the moment.

 

Hi, since you talked about the apple cinema display. hopefully you can help me. i have the 2007(approximate) imac in school. i have a 25' hdmi cable. i was wondering if i were to buy an (HDMI -> Mini Display Port adapter from ebay) non-powered adapter for like 10 dollars. would that work to display my envy desktop on the imac?

and also i have 22"(approx) dell monitors in school. all use dvi. can i use a non-powered (as well) hdmi to dvi adapter?

i just want to save money and SPACE because i already bought the hdmi cable which is really good quality and length. buying adapters would save lots of space.

 

Anyone try an Apple minidisplay to DUAL DVI cable? They are expensive but it could possibly work?

 

My apologizes for bumping such an old thread but I just didn't see a need to make an entirely new one with the exact same issue.

Has anyone tried using (successfully) a newer mDP to VGA adapter with the latest ATI driver update maybe even with the Apple mDP to VGA adapter perhaps? I believe the driver version is 8.771.1.4000 and the update was provided in the driver update thread for the Envy14.
