Displays / Monitors





A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.

HI, I was wondering if there was a hardware way to make my laptop show the display of a vga.  Hard for me to explain, but if I have a server that has no monitor, can I see the display of it on my own laptop?  like a vga to usb with a program or something like that.

Thanks all.
I have an APC UPS and I was trying to load the software to monitor the power supply usage. The software didn't install I think because I have to have the cable connected between the UPS and my PC (see attached images). What type of cable do I need for the serial port on the UPS to either a serial on my PC or USB?

Also, I have three Dell UltraSharp U2412M 24-Inch Screen LED-Lit Monitor with a 16:10 ratio. I have windows behind me that create a pretty bad glare in the afternoons and I was looking for some good anti-glare/privacy screens. Any recommendations? I was wanting one that used a frame instead of the sticky tape. The monitors have the controls on the front of the frame of the monitor, so I wanted something that could accommodate the control. Just looking for recommendations on good anti-glare screens.

Dell Inspiron 14R / Windows 10 will not connect to external HP 2009 monitor.

Connection is VGA to HDMI cable. Windows & P keys & 'Second Screen Only'

Attempted connection returns

"Input Signal Out of Range Change Settings to 1600X900 - 60 Hertz"

2nd Monitor Menu key returns above message

My goal is to use HP Monitor as 'Second screen only'

How do I fix HP 'settings' issue?
My workstation is a Win7Pro with a graphics card running two 55" Samsung 4k TV's as monitors.  For a while now one of them will intermittently go black for a few seconds, then display normally.  It does this for a little while, then eventually stops going black and just works normally.  Some days it doesn't do it at all, then days like today, it just keeps doing it.

How can I figure out what is going on?
How can I look up the graphics card without having to shut down and open up the case?

Both TV's are plugged into ports on that card and are running in DVI mode for PC. I am using HDMI cables.  This has been running for about 2 years, maybe 3 years.  Seems like this started a year or so ago.

Driver updates won't install. It's been a while since I tried, but remember it says something like the updated drivers are not compatible or something like that.
What USB or HDMI device do you recommend on a non-smart TV so I can connect to Wi-Fi and view a website without having to CAST via a laptop like my old Chromecast requires ?
On a Dell optiplex 3050, it has HDMI and DP video ports

The DP port is connected to a Dell H2216 monitor (that monitor also has 1 other port - a VGA port.

The user is asking for a 2 screen experience.

Is that doable on the 3050? Using the HDMI port to another monitor? Or a video card? any recommendation on a video card that would support 2 screens. NOT for anything exotic / fast refresh... just email / word / things like that.

THey are looking at this as a kluge -- they want to use the OLD VGA monitor as the 2nd monitor... thoughts on that? It's an OLD monitor so getting a newer monitor would be an easy pitch to them.  2 the same size / model woudl be good.  Can we just get 2 monitors with DP and HDMI ports on them (or can you convert DP to HDMI or the other way around?)  and connect using the 2 current video ports on the desktop computer?

My computer power starts and goes off back on and then back off all time.

I unplugged the monitor the power does not turn off.

I removed the graphics card (was added to the computer) the computer does not power on.

I changed the power supply, removed memory one by one, changed the graphics card.

Please advise
Setting up a new office (at home).  I want to have a Tivo unit behind my desk.  My desk faces a wall on the other side.  I want to hang a TV on the wall, and get the Tivo HDMI output to the TV, so that all the TV has is a power outlet behind it, so no wires would show.  The Tivo output is HDMI.  The TV is a Samsung TH301 which includes pretty impressive wireless connectivity; they call it a Smart TV.  I find that I can connect to the TV with the Samsung utility on a notebook.  So I could use a browser and cast the output from a separate notebook to the TV.  However I want to use the Tivo remote, not a mouse or touch pad.  Ideally all equipment is in a cabinet in the unit behind the desk.

I visualize operation as using the notebook and its display to connect to the TV, then I switch to get the Tivo output onto the notebook, which would still be connected, thus appear on the TV.

So the solution is pretty simple IF I can just get the Tivo HDMI output into the separate notebook.  I am thinking of some sort of HDMI to ???? adapter.  If I can just get the Tivo output to the screen, I can cast the screen and the Tivo remote will work.  Would be nice, but not trying to preserve the HD resolution.

What is the best adapter or cable for connecting Microsoft Surface Book 2 to an external monitor using a Display port cable?

I have already tried using a general purpose USB C to HDMI cable adapter to connect this  Microsoft Surface Book 2 to three different monitors using an HDMI cable but nothing has appeared on the external monitors when I have done this (even though I have updated all drivers).

Microsoft Surface Book 2 info: 13.5 in. 512GB i7 16GB with GPU.
I am trying to set up a 3 display setup, using a Dell desktop with an AMD Radeon HD 6670 Graphics card the monitors consist of two dell monitors and a Magnavox tv.  One dell is connected using DVI with is the main monitor and the second dell is using HDMI connection, this monitor is touch screen and trying to connect the Magnavox tv using the VGA connection. The system is running windows 10. In display settings, I can see 1, 2, and 3 for all three connections but I never can get all three to display at the same time. When I click and highlight 3 which is the TV under Multiple displays I get Disconnect this display,  Duplicate desktop on 1 and 3, Duplicate desktop on 2 and 3, and Extend desktop to this display.
Display 1 is touch screen using HMDI, Display 2 is the DVI connection main screen, Display 3 is the VGA tv connection.  When I turn on Display 3 and choose, extend to this display Display 1 goes off, and only Display 2 and 3 shows.  Any suggestions on what I am doing wrong?
Hello everyone,

I have no idea how this laptop developed a cracked screen and have been using it for the past two years but just wondering if we could get the screen replaced as the touch screen functionality doesn't work on the left side of the crack.

Anyway, contacted Dell support regarding this and their recommended part number DT2CR costs a total of $221 which is obviously a very expensive replacement for an old laptop.

Could someone recommend something similar at Amazon or eBay? That would be tremendously helpful.

Thank you so very much for your time.

Hi Everyone,
I have a client with Dell Latitude 5580 and a USB-C/DP port with a StarTek dual DP connections and 2 external monitors. She is mobile so she disconnects/reconnects the StarTek adapter  regularly. Recently she tried connecting the StarTek adapter but the laptop does not recognize the adapter or monitors.
I have tried:
>Uupdating the Graphics Driver
>unplugging/replugging the DP connections at the monitor and at the adapter
>Making sure the monitors are set to DisplayPort input
*The monitors do not have a DP out so I cannot daisy-chain them, they have to use the adapter

Any other suggestions?

I bought a Dell U3415 Ultrasharp Ultrawide monitor and connected it to my laptop HP Spectre 360 via HDMI. The monitor is great, however... When the computer goes into the screen saving mode, the laptop starts to continuously exude chimes typical of what we hear when we connect a new device, like insert a USB flash key. That goes on indefinitely until the computer is woken up from the screen saving mode or the HDMI cable is disconnected. It does not matter whether the lid of the laptop is open or closed. I have replaced the monitor with another one of the same model, that has not changed anything. I use Win 10 Pro.  Any suggestions? As a last-ditch measure, I would be willing to turn the chimes off entirely, if I knew how to do it. Any suggestions? Thank you.
My main Windows 10 desktops that I use both at home and at work are both connected to six different monitors.

Are three any utilities that will allow me to define which applications or programs will launch on which monitors?

I would also like to be able to define exactly what part of the screen these programs open on.

Are there any utilities or programs currently available that will allow this to be done?

Hi everyone, I have a customer with a Dell Latitude 5580 and a USB-C/DP port. Is there a DP adapter that will connect to this USB-C port with dual, standard DP ports? I am trying to connect 2 external monitors?MysteryDP

I have a Dell Precision T5400 that I've had for a long time, which has been working great over the years. I recently purchased three new Dell Ultrasharp 24" U2412 monitors. When I installed one of the new monitors and plugged my system back in, I come to find out my power supply went out. So, I took my PC in to get a new power supply and at the same time I had a new graphics card put in that would support a three monitor display. The card I purchased is the following: ATI  Fire Pro card. The previous card that I was using was a NVidia GeForce GT 610 card that came with the system. The new card was installed with the new power supply and the old NVidia card was left in the system. My PC is back up and running, but I have encountered a few issues. First, my audio no longer works. In the sound playback it is showing that the audio is not plugged in, but I've checked and it is definitely plugged in. I believe that it was using the NVidia audio, but now that I have the new  video card installed that might have caused some issue and I need to go into the BIOS and switch to the onboard audio? I was reading an article about making that change. However, the problem I'm encountering is when I boot up, I no longer see the Dell logo screen or the Windows loading logo screen. My PC will start up, but the first screen that comes up is my login screen once the PC has booted up. Until that happens, the screen …
Hi all!

I have a bit of a piecemeal setup at work and I'm looking for a definitive answer regarding my setup, so hopefully someone out there can help me. In short: I want to connect 3 external monitors and close my lid. Is this possible with the following setup, and if so, how are some of the ways to accomplish it? If I need to purchase accessories, I can.

2x P2417H

1x P2414H

I currently am using 2x DP out, but that leaves the third monitor unused. I've been browsing for an hour now and I'm not sure what my options are specific to me. Any help would be appreciated.

Hello Experts

I just purchased the Blue Ray set of BBT Seasons 1-10.  I have a Blue Ray player attached USB3.0.  I've purchased Cyberlink Power DVD 17.  Following multiple errors I get error 0110.  It says "Cyberlink PowerDVD is unable to play this media because the required HDCP could not be initiated.  Ensure your graphics card, its driver and yokur display (e.g. LCD or projector) support HDCP."  

The CyberLink Knowledge Base says "In some OEM versions, CyberLink PowerDVD cannot output Blu-ray and CPRM disc content to analog display devices due to copy protection. To play this content, you must use a display device with a DVI or HDMI input interface that supports HDCP copyright protection."

My PC is a HP EliteDesk 705G3 with Windows 10 Pro, AMD A10-9700 3.5GHz Processor and 8GB DDRH 2133 RAM.  The video card is a Radeon HD7400 Series.  The display is a Sanyo FW40D36F 40" Flat Screen LCD TV.  The PC is connected to the TV using a HDMI cable.  

The Disk set is a UK import, Region Free.  I am able to play other Blue Ray disks (Titanic, Batman, The Hobbit) successfully.

Can anyone tell me where the problem lies?


I have a Gigabyte z370n wifi MB.  It supposedly supports 3 displays. 2x HDMI and 1 Display Port.  My 2 HDMI's work but only mirrored.  The 3rd Display port does not work. It is using an adapter that is HDMI to display port. So there are two issues. Why won't the Computer pick up that it is multiple displays so I can expand separate displays and two, why wouldn't the display port work.  I am not using an additional GPU.  I'm only using the built in for now.  I was thinking maybe some software might help, but I couldn't find any drivers or software on the Gigabyte website.  Thoughts?
I had a follow-up question to a my previous post.

I had contacted a Dell rep about the new 24" U2412M monitors that I looking at purchasing and mentioned the graphics cards in my previous post I was considering purchasing to support the 3 monitor display. They indicated my current system, which is a Dell Precision T5400 might not support the card due to lack of the necessary power/wattage needed for the card. The rep came back and said that the cards would be supported with the power, but said the only Dell approved card was the Dell 2 GB NVIDIA Quadro NVS 510 (4mDP) (4mDP-DP adapters), 9NPC8 ((4mDP) (4mDP-DP adapters) (QMGA3) (Kit)) . They provided a very expensive quote for that card. I checked on Amazon and found a much lower price point, which made me concerned they were blowing smoke and that any of the cards listed in my previous post would work in my existing system. I also found that the price on Amazon for the monitors I am going to buy was $50 cheaper than the quote I got from the Dell rep.

So, I'm wondering if I'm being scammed by being told that the approved card by …
