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.

We have received a HP laptop that does not turn on properly.

It seems to be a Windows 10 laptop.

I have tested this laptop and what happens is that the laptop powers up fine, goes to login screen fine but after logging in there is only a black screen displayed on laptop screen.

Every 10/ 20 seconds, the login screen loads back and when you click anything on keyboard, the black screen displays again.

Here are some things I found:

- The mouse pointer can be seen over black screen.
- Pressing "Windows key" and "P" brings up Project menu with four options which can be navigated through but not picked
- Ctrl+Alt+Delete does not do anything
- Ctrl+Shift+Esc does not do anything
- After black screen displayed for a few seconds, pressing a key makes the black screen slightly brighter

What should we do to fix this issue?

can someone give me an opinion about this strange bar that appear on my laptop screen when i turned it lnw and disappear after a few minutes ?

Thank Strange Bar on my screen
Mac mini 2018 Mac OS 10.14.6 Supplemental Update 2 no longer supports 2 displays (Monitors).

At Startup, System will not display screen on both monitors, swapping displays or using single display in each of 2 does not resolve issue - both monitors (1 at a time) work OK using either of 2 Thunderbolt connectors.
Have a client who wants to use - Samsung LC49J890DKNXZA 49" 3840x1080 Super Ultra-Wide Monitor with USB-C for Business as their monitor to replace (x3) 22" Displays.  One of which has burned out.  The computer is a newer Dell XPS Special Edition (2019) with i7-8th Gen and big video card.  The video card has mini-display ports, and this monitor uses USB 3.1c.  I have not worked with monitors connected only by USB 3.1c.  What can anyone tell me to look out for?  Will this only work with onboard graphics or the discrete video card?  Can he add additional mini-display port monitors?  The existing USB 3.1c hub would connect after the monitor, but will this be a problem with USB 3.0 devices, like backup HDD?
 I have Nvidia GeForce GTX 1050Ti video card in my computer and like to know if I buy a 10-bit capable monitor, this video card can produce 1.07 Billion Colors?


Strange thing today.  My computer monitor messed up and just replaced it with a temp monitor.  All works fine but Netflix won't.  It gives error:

Error code: U7361-1255-C00D7159

Open in new window

When searching the error, I have:

Netflix Error H7361-1255-C00D7159
If you experience the error code H7361-1255-C00D7159 on your computer, it's typically caused by using an unsupported video output method, such as a Wireless Display Adapter. Netflix is only compatible with video output methods that support content protection (DRM). To immediately stream on your computer, follow the troubleshooting steps below. To successfully watch Netflix through a video output method, contact your device manufacturer to learn which devices support DRM protection.

The strange thing is that I only change the monitor.  If I move the Netflix apps to the notebook (my computer is a notebook with an external monitor connected), it works, so it seems it's the monitor.

The setup is:
- the notebook has an USB connector
- in that connector is a Insignia USB to Hdmi and an USB cable connected to the monitor.  I had this same setup with my old monitor.

Please let me know whats going on or is it a configuration.
Is it possible to manually assign monitor's number sequence in window 10. I would like to make monitor 3 monitor 1.
I keep getting a "No Signal" message on the TV when I plug a PC display port cable into my Sanyo TV. The cable I purchased is Display Port to HDMI.
I have a Lenovo pc and am running Windows 10.
I have attached pictures of pc bios settings and a diagram of the back of TV.
I want to see my PC image on my TV screen.  That's my goal.

I thought that I would be able to use a micro-usb to usb-c cable to pair this Magedok T1116D 1080P FHD Capacitive Touch Portable Monitor shown here http://magedok.com/touch-screen-monitor-t116c with this Microsoft Surface Go device https://www.microsoft.com/en-us/p/surface-go/8V9DP4LNKNSZ/L8M8?activetab=pivot%3aoverviewtab.

While the monitor does come on when it is plugged in using only the micro-usb to usb-c cable, it says "no signal" very briefly, and goes to black.

Is there any way to pair the devices so that the second screen will function?

I need a portable swivel arm that secures to the edge of a table for my Magedok T1116D 1080P FHD Capacitive Touch Portable Monitor shown here http://magedok.com/touch-screen-monitor-t116c. It does not have VESA holes on the back despite the picture that shows them.  The screen is 7.5" tall when turned to landscape view. That's the shortest distance edge-to-edge, so the arm needs to be able to hold that securely.

The two pieces that I purchased on Amazon are noted below, and while they are portable enough to put in a laptop bag, which I like a lot; they are not sturdy enough to hold the Magedok where it doesn't move around too easily.

If I find something that works, the plan will be to get it fully assembled and leave it fully assembled so that I can just pull it out in a ready state, and attach it to the side of a table when I am ready to do a demo in a public place.

Assistance in finding the right monitor arm to give me this perfect balance between sturdy and compactness is greatly appreciated.
We have one brand new HP EliteBook 850 laptop that is used with an HP docking station and 2 ViewSonic Monitors. All 3 screens are used in this case (laptop monitor + 2 ViewSonics).
Every night the laptop is powered off. When powered back on in the morning, 'sometimes' the screen orientation is lost. Meaning 1-3-2 becomes 1-2-3. and of course mouse travel from left to right doesn't work anymore. When the user takes the laptop home with him and returns in the morning and re-docks the laptop, the orientation is always messed up.
Any ideas on why this happening?
We are able to reconfigure each morning so that the monitors work as 1-3-2 and the mouse moves from left to right across all three screens.
I have a Commodore 64 working with video cable and 1702 monitor. Will the same cable and monitor work with a Vic20?
I need to decide on a brand and model for a new monitor. The computer is a Dell Precision Workstation T3600 running Windows 7 Ultimate. The graphics adapter is an nVidia Quadro 600 with 1GB memory and DVI and DisplayPort outputs.

The usage is basic - Microsoft Office (Excel, Word, Publisher, some PowerPoint), email, web surfing. The monitor needs to be about 27" to perhaps 30" - it has to fit some tight space constraints on the desk due to an overhead hutch. Single monitor - no dual configuration.

A thin (in front-to-back depth) model will be helpful given the space constraint.

I want a highly reliable brand. Presumably a fairly basic or intermediate performance monitor will suffice.

In the past I have always used Dell monitors. Should I continue that? Or do you think there is a different brand/model I should consider this time? Please share your reasoning.

Thanks, Pete
I think an old Dell 2709W monitor just died but want to check if I am overlooking anything. The monitor display suddenly became a mess of unreadable, moving colors. I did not take a picture of that but have two others below.

Here is a picture of the monitor's on screen menu:
on screen menu
And here is a picture of the text that moves around the monitor screen while no input is active:
screen saver with no input
The monitor looks the same way when disconnected from any computers and video input cables. The computer to which the monitor was connected when the failure occurred is working fine connected to another monitor.

I cannot read the on screen menu enough to try resetting the monitor to factory defaults.

In your experience is there a way to possibly restore proper operation of the monitor? Or should I stop investing time in it and replace it?

Thanks, Pete
need advise on a good 4k color correction screen. this viewsonic seems to do the job but when comparing with this dell im not sure (forget the price for now)

the dell seems faster with response time

and the dell has all the adobe rgb colors while the viewsonic at 78%... does this make a huge difference for editors?

I am putting together what I call a computer audio workstation for my office. To cut to the chase, what I want to do is use BOTH a Toshiba laptop a Dell desktop along with an external CD player/burner.  i will also be recording vocal stuff using a couple of microphones routed  to computer through a Berhinger Eurorack mixer.

I'd like to use the screen on the laptop as a monitor for the Dell for certain applications.

I know this sounds a bit old school, and it is. I have some specific audio recording work I'm planning to do on a regular basis and have determined hat a separate audio workstation will  enable me to do it easily and  save time.

What do you recommend?

How do you adjust the size of a maximized window to fit a particular monitor?

When I maximize a window, it is slightly larger than the viewable area on my screen. As a result, the outermost border of the window is not visible due to being obscured by the black edges of the monitor.

The thickness of the obscured edge appears to be 12 pixels on all sides. This was determined by running the following AutoHotkey script:

WinGetActiveStats, Title, Width, Height, X, Y
MsgBox, The window position is:  %X%, %Y%, %Width%, %Height%

Open in new window

The monitor resolution is 3840 x 2160. However, the script returned the following:

      The window position is:  -12, -12, 3864, 2184

So this shows that the actual upper-left origin of a maximized window is -12, -12, rather than 0, 0 as it should be. Also, window width and height of 3864 and 2184 exceed the horizontal and vertical screen resolutions of 3840 and 2160 respectively. In each case, the difference is 24 pixels.

Connect 3 monitors to Mac mini [late 2014] - OS X Mojave 10.14.5 only any 2 of 3 connected are active displays.

2 connections are Thunderbolt/VGA, other is HDMI/VGA.

I can have temporary access to Mac mini 2018 - will this solve 2 of 3 --->all 3 issue?

I have a Lenovo X1 Carbon that was working fine until recently being update to Win 10 1903. Everything tested so far has been fine except the 3CX Soft Phone client. It will not display on the builtin monitor. If I attach another monitor, set the monitor as primary, then it will display on the second monitor. I can drag the Soft Phone to the builtin monitor and it will display fine. Once I disconnect from the monitor and restart the Lenovo I cannot see the Soft Phone. I have tried many screen resolutions and nothing seems to alter that. The builting monitor is using Intel graphics drivers. I have updated them and still no good.

This is a touch screen display. The X1 with the issue is 2nd gen. I have a seventh gen X1 (non-touch screen) and it is working fine. Same OS - Win 10 ver 1903
I currently have an Nvidia Quadro P2000 card, and I am installing (2) 50" 4K monitors, that require a 40' HDMI cable.
My video card is Displayport, and I don't want to have to have an adapter from Displayport to HDMI, so i've been looking for
Display port to HDMI 40' that does 4K and I can't find any.

Should I change my video card and go with a video card that is HDMI?   If so, what would be a good one that supports 5 or 6 monitors, full 4K resolution?

I'm thinking at this point, I might just try a 40' HDMI cable with a Display port adapter, but the HDMI cable will be in the wall, so I can't replace it if this
setup doesn't work.

Any suggestions?
How do you stress test a video card?
How  can you push the limits of a video card?
How do you find out the limits of a video card?
How to you test if a video card is working correctly, beside running a hardware diagnostics?
Hello and Good Morning Everyone,

           I wish to add a third HDMI device to my VIZIO television, but, it only has 2 HDMI ports.  That said, I am wondering if there is a device which can be hooked up to my television which would extend or add HDMI ports.  In concept, it would be similar to a USB hub.  But, I am unsure if such a device exists for HDMI interfaces.  

           Any shared thoughts or suggestions would be greatly appreciated.

           I look forward to hearing back from everyone regarding this question.

          Thank you

Any alternatives to Teamviewer that allows for dual monitors?   I need to setup a user to be able to connect from her home desktop (Windows 10) using dual monitors to her work desktop (Windows 7 Pro) to use her dual monitors there.   We're a very small company and the cost of Teamviewer is out of our budget.   Anyone successful out there without breaking the bank?

We have a user that has a burned in image on his ThinkPad W530. The example is below and right near the cursor you can see writing and what looks like a bar going across the screen. We have changed the background and to different pictures but this is burned into the screen. Is there anything that can fix it besides swapping the screen out?
