Resolved What is causing inverted black triangle, centre of screen?

@ Bill, the PSU in the HP Omen is 500W.

The onboard graphics are usually VGA (15pin) but the Omen may have HDMI??
Bobby, the graphics card installed as new has a DVI connection which is getting to be normal these days and the VGA is now in the 'old' bin.
This setup I am using has a 27" ViewSonic Monitor and the cable between my GT740 card (in the comp) is HDMI to HDMI.

 

Very interesting. New monitors offered, are they sold with HDMI cable/connector? Will need, my checking connector types carefully before deciding on new monitor.

 

Okay, but that's no guarantee it will be sufficient for any card that may go in there - especially if it does not have a relatively flat efficiency curve. But this is irrelevant if not replacing the graphics solution.

 

Are we referring to the current monitor in use? as I have no intention of replacing the 1080 graphics card.

 

@Bill, as I understand it this was the OE setup for HP Omen that Bobby bought brand new just 12 months ago. The card is original.

Bobby.

I am not sure. The choice at your card is for 1 x DVI and if you are just going to use 1 x Monitor you will be best to ask for a DVI to DVI cable of the length you require from the supplier.
Multiple Monitors can be connected by using the multi HDMI connections on the card.
As I have noticed, most new monitors have DVI and HDMI connectors. You will be able to seek advice from the suppliers when/if you purchase a new monitor.
As Bill has Posted the views of the various types of connectors available/in use, you should be able to recognize the connector you have in current use on your monitor and computer.

 

Certainly I am not going to use multiple Monitors now or in the future, space for one monitor is all that I have available. I am basically just a minimum computer user and leave all the fancy stuff to the young generation of gizmos users.

 

I am not suggesting or implying his PSU is inadequate. I was only saying if he (or anyone) is considering a different graphics solution, they must ensure their current power supply can support it. This only stemmed from the fact Bobby's monitor is 8 years old and may not have DVI, HDMI, or DisplayPort connections. He also said his computer had a 15-pin (D-Sub) connection but did not mention a digital connection. Since digital is the way to go these days, if getting a new monitor, and if the computer only has D-Sub, a new card may be in order.

 

According to my Display set settings: 1920x1080 Refresh rate 60Hz. No HDMI display available.
Graphic Card and Display are HDCP capable. DVI - PC Display.
I do not think that HP would fit an underrated PSU. Monitor presently in use is functioning adequately for my needs.

 

Bobby, many would argue otherwise. My wife's first computer was a Pavilion model with a 180W PSU - it barely handled the loads.
Other model HP Omen comps (less specs than your one) are supplied with a 300w PSU. Not large by todays norms but just adequate.

 

RL, being so ancient in my thinking, if aint broke leave well alone. It is a certainty, trouble of some kind will come along looking for me and that is a certainty. Regarding PSUs, you are hundred per cent correct, my previous computer's PSU packed in after less than two years, without prior signs of packing in. Replaced that PSU with a 500w capacity, and stupid me dumped it with the last computer. It is only expected that HP will fit a minimum capacity PSU, just to protect HP high profits margin.

 

You are right - but just barely. Many of these factory built computers come with supplies that are just barely adequate for the components they come with. But as soon as users attempt to add anything, even something as little (in terms of power requirements) as another hard drive or another stick of RAM, suddenly that factory installed drive becomes inadequate. And worse, they are often proprietary so you have no choice but to buy from them.

Also, all power supplies (even the best quality supplies) weaken as they age. Some compensation capability is built in, but they still weaken.

But this seems moot if you already put a 500W supply in ther.e

 

Bill, in my previous reply, I did say that I renewed the PSU with a 500k and unfortunately ditched it with my last computer and not the current HP OMEN. What you say about factory built machine absolutely correct, as my HP OMEN is a prime example, in its early days of use, was a complete nightmare. Is there such a computer built that is completely reliable? I have bought two HP of different models and each time bitterly regretted in doing so, after sale to me was none existent.

 

Until Man can create perfection 100% of the time, the answer will always be "no" - especially when those computers are built for profit. This is why I have been building my own for me and my clients for 25 years.

Because I cannot go to ASUS, Western Digital, Microsoft, Intel, EVGA, Antec or Micron and promise to buy 1,000,000 motherboards, drives, Windows licenses, processors, power supplies, cases or RAM sticks over the course of the next year, there's no way I can compete in price with HP, Dell, Acer, etc. But (at least IMO) I can build a better computer in every category, much more closely suited to my needs and those of my clients. But that does not mean I still won't have a PSU or motherboard fail prematurely.

 

You are absolutely correct in what you say, and still you depend that each part used will be dependable. . One thing no longer carried out by manufacturers "quality control", they realised it was more cost saving to ship out all production and wait to see how many failed were returned, just replace that failed item, cutting out the cost of employ personnel to check for possible failure. To find someone like yourself to build a computer "reliable", in my part of the country, is a non- starter.

 

Bobby, from your Profile your HP Omen specs:
OMEN by HP Desktop PC - 870-206na Product Specifications | HP® Customer Support
This model was also available with a 500W PSU for Gamers.
As you don't do any gaming - you probably have the 300W PSU. Physical identification may be necessary.

 

That is a very good question, what size of PSU is fitted in my computer. At time of buying computer, I was unaware as to size of PSU fitted, as I believed the computer was a Gamer machine at a cost of £1100. It would help me as to procedure to find this information 300w or 500w.

 

You will have to remove the side panel to find the info as per image.

 

RL, Yes as you say, side panel has to be removed to enable access to information label, thank you for pointing this out. It appears that the PSU passes not information to the motherboard. I have learned from HP Help Forum, that the OMEN 280-203na is as you said a Gamer Machine but can also be used as an Ordinary daily used computer, is fitted with a 300w PSU, it then points out it is better if fitted with a 500-600w capacity PSU. Now, it proves HP does fit components barely adequate for purpose, but it increases their required high profits.

 

No PSU that I know of does. That would require some sort of firmware in the PSU to maintain and provide that information to the motherboard. And it then would require a data cable from the PSU to the motherboard. There is nothing in the ATX Form Factor standard for ATX compliant motherboards or ATX compliant PSUs allowing for either. I note both would increase costs for little value in return.

Kinda sorta but not really. In fairness to HP and other makers who do the exact same thing, if they use over-powered power supplies, they would have to charge more for the computers when new. And then users would complain they are paying for something they don't need.

Just because a computer is able to be updated, that does not mean HP, Dell, Acer, etc. should automatically use extra large power supplies from the start to support those upgrades. After all, most users never upgrade their computers as the thought is users should be buying what they need from the start.

It reminds me a friend who complained he had to have a hitch installed on his SUV so he could tow his new fishing boat to the river. He said all SUVs should come with a towing hitch. I told him most SUV owners never need a hitch so why should they have to pay more for something they will never use?

Then I asked him why he didn't buy a SUV or truck with a hitch in the first place when he bought the SUV if he was going to be towing a boat? He said he didn't know he was going to buy a boat 2 years later. So is that the SUV maker's fault?

Nope.

Now he's complaining the little 4 cylinder engine in the SUV has a hard time keeping up with the highway speeds when he's towing the boat. So I asked him why he didn't get a SUV with a bigger 6 cylinder engine?

He gave me a dirty look.
