HP Z420 (LJ449AV)
Microsoft Windows 10 (64-bit)

Hi,

 

Currently I have a problem with my HP Z420 v2 (Xeon E5-2680 v2, 64 Gb) : unable to connect a VGA screen with adaptator HDMI => VGA on a MSI GEFORCE GTX 1050 TI 4GT OC. Black screen, no error beeps, workstation boots.

 

The adaptator works fine on another computer with same graphics card and display. Tests made with 2 HP display w2216w and S2331a.

 

My Z420 has the latest bios installed (03.96 Rev.A). Power supply 600 W HP. No power connector needed for this graphics card (75 W). 

 

It's OK with the DVI connector and another display...

 

Thanks in advance for your help.

Hi @BambiBoomZ,

 

So I can confirm that with an active HDMI to VGA adapter I don't have a black screen from the initial display of the bios, and that with my VGA display I can work normally on my Z420 ! I am installing VMware vSphere Hypervisor 7.0 (ESXi).

 

Adaptor found on Ebay :

Thanks again for your help with your answers.

 

See you soon for new adventures !...

you should already know the answer, either the card/video adapter/monitor you have refuse to play nicely together

the solution is to simply replace one part,

 

due to the shear number of devices in the pc world, there are cases sometimes where some parts will not work together due to how the individual  products are designed replacing one part such as the adapter vid card or video monitor will resolve the issue

 

if you have a different monitor try it.... as your existing monitor may not like the existing video adapter and can't detect a video signal, hence the black screen or try a different video in as most monitors made in the past 7 years have multiple video in ports

@DGroves,

 

As I told you the graphics card, adapter and display work fine on another Core I7 based configuration. So the adapter / graphics card / display compatibility issue seems a bit dubious to me.

Except a compatibility problem with the Z420... What I'm trying to figure out.

So that's why I allowed myself to ask the question.

But thanks anyway for your answer which did not advance the Schmilblick as Coluche would have said.

 

[EDIT] : 

 

Having to absolutely be able to use my workstation, I therefore mounted an old Radeon HD 6670, which works perfectly with it.
Too bad considering the price of the Z420, even used ...
End of the story.

John_McClane,

 

0.  Just checking; when you say "VGA" do you mean "DVI"?  I'm not aware of a GTX 1050 Ti with a VGA output.

 

1. Consider booting to setup (F10) > Advanced > Slot Options and checking that the primary GPU slot (Slot 2) is enabled and set to Auto- which will = PCIe 3.0 x16 or reset it manually to the highest setting.  Check and, if necessary, correct the settings for the 2nd GPU (Slot 5)  slot also.

 

2. If that does not solve the problem, consider trying the GPU in the secondary  GPU slot. If it works, then there may be a new problem with Slot 2.  Can you try another, known working, GPU in that slot?

 

3. If neither 1 nor 2 works, consider trying a different port and adapter on the  GTX 1050 Ti, e.g., : DisplayPort > VGA (or DVI).

 

4. In my experience HDMI  cables vary in quality and can be "temperamental".  The situation may be better now. I use a Samsung 40" 4K TV as the monitor for the office z420_3 - it has 3X HDMI and no DP input  -and (two years ago) that required three HDMI  cable experiments before the expensive Tripp-Lite cable worked properly.

 

It's a mysterious problem. There's an outside chance that  the primary Decasimüchron timing is out and affecting the Pendantascope saturation.

 

Let us know what you find out.

@BambiBoomZ,

 

Thanks for your answer.

 

 

0. It's an adaptator "HDMI => VGA", no VGA output on my graphics card. 

Same graphics card and adapatator are OK on another HP computer (Core i7 880 - 16 Gb).

 

1. I did these tests correctly as soon as I encountered the problem. The slots are well activated, in automatic speed, and the same when playing with the speeds on the 2 PICe 3.0 16x slots.

I made a default reset of the bios config.

With GTX 1050 Ti's DVI-I connector on a DVI display it's OK. 

With an very old Radeon HD 6670 1 Gb, no problem with 2 slots PCIe x16.

 

2. I have tested the secondary slot, same problem. 

 

3. I cannot test with a "display port => VGA" adapter, there is not enough space to plug it into the card. And I don't have a display port to VGA cable (if it exists). 

 

4. I will test another adapter, this one active. We'll see.

 

Yes, it is a mysterious problem. Yes, we are in the fourth dimension ...  🙂

 

 

Bye !

1x DVI,

1x HDMI,

1x DisplayPort

 

Reviewing 1,2, and 3 above, in consideration of the fact that VGA does not have the bandwidth to support HDMI, and that HDMI is unnecessary as neither monitor supports the audio component, consider purchasing:

 

1x DVI to DVI cable  > Connects GTX 1050 Ti to HP s2331

1x DisplayPort to DisplayPort cable  > Connects GTX 1050 Ti to HP w2216v

 

And in that way, both monitors may be connected simultaneously and without any signal conversion.

 

Over time, I've found two monitors to be indispensable; the left with the active application, the right with  second+ applications, menus, Winders Explorer, supporting documents, images, the inevitable UTube Mahler controller, & etc. In review, I may need three monitors,...

@BambiBoomZ,

 

I have a HP S2331a with my other HP computer.

 

My VGA monitor is an HP w2216w which worked perfectly on the same graphics card with the HDMI to VGA adapter. I used it in double with the HP S2331a monitor in DVI.

 

That's just why I'm wondering about this "problem" on the HP Z420.

 

I'll either see about testing another active HDMI to VGA adapter, or I'll change my VGA monitor.

 

I'll come back to give news.

 

Thanks again for your answers, @BambiBoomZ and @DGroves.

3. GTX 1050 Ti Outputs:

1x DVI,

1x HDMI,

1x DisplayPort

 

It's a detail, but the above does not align with the statement, "My VGA monitor is an HP w2216w" as it appears that it is the HP s2331 having the VGA input.

 

That the GTX 1050 Ti does not have a VGA output and the signal is passing through an adapter may be the entire problem. All of the GTX 1050 Ti outputs have a higher bandwidth than VGA which is one of the earliest specifications; HDMI surely and  DisplayPort possibly can not be easily squeezed through VGA.  Overall, it's best to use the most modern, most direct connections available and avoid any level of signal conversion.

 

There is not an obvious why the z420 should not work in the same way as the other system, except that the z420 being newer is possibly not 100% legacy supporting . In any event, I strongly recommend using only the direct / same connector cables and take both VGA and HDMI, out of the equation:

 

 DVI to DVI cable > Connects GTX 1050 Ti to HP s2331

 DisplayPort to DisplayPort cable > Connects GTX 1050 Ti to HP w2216v

 

These small details often seem to produce strange complications: "Just a fly in the ointment, Hans. The monkey in the wrench."

OK,

 

The answer is here : the Pascal generation of Nvidia has only digital outputs ; so you need an active adapter to convert  a digital signal (HDMI) to an analog signal (VGA).

 

Yes, the Z420 is newer than the other PC.

 

I therefore close this subject by thanking you once again.

 

Bye !

John McClane,

 

Sorry to press this point, but the reason mentioned in the previous reply- that of requiring an active converter for VGA is the reason for mentioning avoiding both VGA and HDMI.  The GPU and both monitors listed can avoid the need for that conversion and eliminate that as a possible impediment to the system working. The purchase of one DVI or DP cable depending on the monitor may solve it. I can't think of any other component relating to the problem that is as suspect as the converter.

 

I apologize if I've annoyed you in this conversation.
