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.

I need an inexpensive KVM that supports three (3) display ports.

I can't seem to find anything under $100 that supports the DisplayPort (dp v1.2 or 2) and does this all in one device.

Assistance is greatly appreciated.

This product works and I have it but it needs to support the third computer.  It only supports two.

On my Dell 24' touch monitor the cursor jumps horizontally when I touch the screen.
The electricity is connected to converter from 24v to 220v. I have tried to connect the monitor to my
laptop and my desktop but it works the same way on both computers.
All other equipment connected to the convertor like TV , PC and some navigation instrumnet works fine.
But when I connect the monitor to normal 220v outlet it works fine.

A coworker recently obtained a new docking station for her laptop and complained that her external monitor seemed "fuzzier" than it was.  Originally, we had her laptop connected via HDMI.  However, our IT support company connected the docking station with a VGA cable.

I theorized that the switch from HDMI to VGA was probably the cause of the video degradation.

When switching between the VGA of her docking station and "hardwiring" an HDMI directly from her laptop, she felt that the display did look better.  The difference seems barely perceptible, but I can imagine that staring at the screen for hours on end would make a difference.

When I looked at her new docking station, I noticed that there is no "HDMI out" port.  Rather there is a VGA, two DVI, and two DisplayPort (DP) out ports.  Her current monitor is only capable of connecting via VGA or HDMI cables.

Given this configuration, would you agree that connecting a DP-HDMI adapter to the docking station, and then an HDMI cable from adapter to the monitor is the BEST solution in this case?  Other than purchasing a different docking station of course.

It looks like I can purchase a DP-HDMI adapter for about $25.  So that's the way I'm leaning unless any of you experts believe there is a better solution.
Windows 10
External monitor  24"  hp compaq la2405x
lenovo think pad t430s

I have 2 problems
Ever since i went to windows 10 the scale is always off....programs too big for the screen. Laptop and external monitor.
Laptop screen and monitor screen flickering back and forth ?

I have a particular area on my wall where I would like to mount a 70" big screen flat panel TV that needs to be extended (offset) around 3 feet from the wall (so that it won't obstruct a wall vent).

What are some good flat panel TV mounts that will allow this to be done?
What are the best rotating or pivoting ceiling TV mounts that will allow for a 70" big screen flat panel TV to be pivoted at a 120-degree angle so that the TV will be visible from different locations in the room?

I need to have this TV visible from one vantage point while I am sitting on my recliner or couch and then visible at another angle while I am sitting at my computer desk.

What are the best rotating ceiling TV mounts that will allow this to be done?
We have a user with a laptop running Windows 10 Pro. She has an external screen connected that she extends the display too, in order to use both screens.
Recently the external screen have a space between the window she is working on and the task bar. This space either shows that part of the desktop or just duplicates the bottom part of the window. It is not always there but randomly appears and then stays until the computer is restarted.
I have attached a screen shot as and example.
It only does this on the external screen display. Not the laptop display.

I have done the following.
  1. Uninstalled, rebooted and reinstalled the graphics drivers
  2. Installed all Windows updates.

Has anyone come across this before and is so how can I resolve this issue?

Thank you

I'm looking for a product that is the combination of the following 2 items:

ie an adapter that could connect to iPhone/iPad's Lightning port or Android's microUSB
& can output to TV HDMI as well.

Can point me to an eBay/Alibaba/Amazon link that has photo & selling that item?
I need to make my laptops ( Lenovo x230t and Macbook Pro 12" retina released in end 2015)
to be able to receive HDMI inputs (rather than the usual HDMI outputs) so that I could watch
Netflix streaming from my Telco's Set Top box : basically watching movies from 2 bedrooms

Any gadgets/accessories to recommend?  I guess softwares alone on the laptops won't work
or will it?

I do have 21" LCD computer screens that I can spare but they don't have HDMI input ports,
only VGA input ports (maybe with audio inputs)

I am using below extended monitor.

screen looks very bright to my eyes

i could not find any option to reduce brightness.
on right hand side bottom corner i see some buttons like 5 of them.
First one from last is to switch on and off
other four are very clear to me
i played around but no luck to reduce bright ness

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 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?
DP-USB C connection
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
