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 am running Windows 10 on a Lenovo P71 laptop.  I have a 21" Acer monitor.  Since getting my computer I've been running my monitor off the laptop's USB-C port, and everything works fine.  But I needed the port for other things, and used the HDMI output on the laptop to the HDMI input on the monitor.  The monitor has two picture settings:  Aspect or Normal.  The Aspect setting fills the wide screen monitor, but everything's stretched.   Normal just provides an old 4:3 ratio, with the display in the middle of the screen.  When viewed through the USB-C port the widescreen worked fine with no distortion (as on the laptop screen).  How do I have the HDMI connection work properly?


Suddenly, my monitor has started flickering.   I have an nVidia GeForce GTX 1050Ti connected to an Asus PA328 monitor Display Port.   I am running Windows 10 Pro 64 bit.   Suddenly, my display has started flickering.   I had tried Ubuntu without installing it, and that seems to be when the flickering started in Windows.   I do not know if there is a connection.
This machine is one I built recently.  I want to use the two video ports to run two monitors.  The problem it is having is when both the DP port and the HDMI port are connected to monitors, it hangs at the initial boot screen, the one that comes up like 2 seconds after I press the boot button and has all the F key descriptions at the bottom of the screen.  If I unplug the HDMI cable and press the boot button, boots fine.  If I reconnect the HDMI cable and "Restart:", it boots fine and runs both monitors fine.  It is only when booting from a shut down with both the DP port and HDMI port connected to monitors that it hangs at the F key screen.

I have been using a HDMI to DVI adapter to DVI cable to run the 2nd monitor.  It is this cable that when I unplug it, the machine boots fine.

Alternatively, when I unplug the DP port cable and leave the HDMI to DVI connected, it will boot fine.

And another alternative, when I boot it with one cable plugged in and then wait until it gets past the F key screen, the plug in the 2nd cable, it boots fine and both monitors display.

What can I look at to resolve this issue?

One more thing I tried and this may be a whole other issue, I bought a HDMI to DP cable and tried running from the HDMI port on mobo to the DP port on the monitor, but get no signal.  Wonder if that is just a function of the HDMI cable from mobo port won't run the DP port on the …
I need HDMI 1 in 3 out splitter  that will extend to 3 monitors.  Hopefully will be able to order on Amazon or best Buy and will not be expensive.
Windows 10 build 1803: monitor detected wrong

I got a laptop (Dell Latitude 5580) connected to a docking station (USB C). It has 2 monitors connected. A Dell 19 inch (1280x1024) and as primary a HD dell monitor (1920x1080).

All well, but now I replace the old 19 inch to a dell HD (also 1920x1080) monitor.
Windows "sees" the old 19" model, and refuses to detect the nw monitor. Even by restarting (obvious), removing the drivers from device manager, all done, I can't set the resolution higher than 1280x1024, making the new monitor blurry.

Tried a lot of things but no avail. Tried to put the monitor on the laptop itself over VGA and this seems to go well. Putting it back to the docking makes windows detect it as the old monitor. Is there a wat to realy force Windows to use the native (higher) resolution?

Display Drivers are updates, and I tried to manualy put the monitor te a generic HD monitor.  The displaycard id an integrated Intel HD620.
Hi Why my second monitor attached to my pc has a black mark? Please see the picture attached. and the black can move, but my eyes cannot see the moving unless several days later i can see the the mark already moved to other location on the screen. Thank you
Is it ok to use a vga to HDMI adapter to connect a spare smart TV that I have to a mini server?  Heard the quality is not good as it is a analog to digital conversion but not sure if this will damage the smart tv.  I use the smart TV for a trade show and when not in use, I'd to use to as an external monitor (so that I can put it in use).  It is at least 42 inch.
Hello experts,

I have an issue when I log into W10.
A black flashing screen appears.
I can continue with my tasks after this however I would like to know why I am getting this and how can I fix it.
I attached a video performed with my smartphone (black flashing screen appears between 8s-9s)
If you have recommendations and feedback on this please let me know.
Thank you in advance for your help.

Hello All;

OK, a few weeks ago my son called me while I was working and informed me that he had placed his drink on my desk, and my granddaughter hit it causing it to spill all over my laptop.
I took the system completely apart and cleaned it with alcohol, and allowed it to dry for the weekend, before re-assembly and turning it back on.
Everything is working great, except I have to replace the keyboard, and am just waiting for the slow plane from China to arrive, to get it in.
This question deals with the monitor.
I have dual monitors connected to this laptop and the external monitor is fine, so this is not a graphics card issue, but a monitor issue.

Do I need to replace the entire monitor? (Do not see this as the answer)
Do I just need to replace the LCD screen? (This is what I am hoping)

Attached is a video of the flicking of the monitor.
Please let me know what my next step should be.

Thanks all.

Surface Laptop 2 will not display on dual external monitors when connected to Surface Dock For Business

I have a client who has a Surface Laptop 2 and two HP Monitors. She wanted to connect the monitors to her Surface Laptop 2. So I recommended the Surface Dock for Business which I have for my Surface Pro 6.

She has all the cables and adapters for the dock & monitors. But when she attaches the dock cable to her Surface Laptop 2 both monitors display that there is no signal. The Surface Laptop is getting power from the dock and if we connect keyboard & mouse via USB they both work.

If I attached my Surface Pro 6 to the same dock both monitors get signal.

I have tried all Resolution and related settings but when her Surface Lattop 2 is connected nothing.

The Dock supports the Surface Laptop 2 so not sure what is happening or what to try.

Any ideas?
Having purchased Affinity Photo, Publisher and Designer, quite by accident I pressed and held down a. control an on-screen display of most functions.

This same as hovering over a control. e.g. View Tools [H], but for most - if not all - controls for the current.

How did I do this?

This a most valuable function!
I have a new PC with two Displayport connections for my monitors.  My monitors only has a VGA connection and an HDMI connection.  Would it be better to connect the monitors to the VGA connection or the HDMI connection?  I need to purchase the adapters and need to know which would be better to connect to. (VGA to Displayport or HDMI to Displayport).

Thank you

How to view and take screenshot of 'About' screen so entire 'About' page fits on the screen?
We have two LG 43SM5KB-B displays.   They were connected using the SuperSign software but recently we had issues with it.  I have tried to replace the input by connecting them to Windows 10 computers.  When I power them on they detect the RGB connection and display the output from the computers.    After a couple of minutes they reset to what was previously displayed using the SuperSign software.  

Once the display has reset none of the controls work.  I can not view settings change input etc.   I have tried to review settings but before I can get very far before the screen reverts to the previous SuperSign presentation and the menus do not work.  

How do I stop them from reverting to the old SuperSign presentation?  Or how do I reset them to defaults? or How do I access the menus and turn this off?

I have powered the displays off and uplugged them. Verified the computers are set to never go to sleep.   Set the input to RGB (before the screen refreshes), disconnected the wired connection (i can not get to the wireless through settings before the screen resets).

Thanks for any help you can provide
I have a legacy application that doesn't optimize for a resolution above 1024X768. As most of you know these days new computers and monitors want much higher resolutions. Does anyone know how to make a new computer and widescreen monitor work \ scale to full screen with a 1024X768 resolution?

I've been using a SAMSUNG TV as a second monitor for months now. I woke up today and the screen isn't the same.

The browser top and edges were cut off so I couldn't see the close box and header area. The text is all kind of pixilated. Not crisp. Same with images. Just really poor quality.

I haven't changed anything that I know of, unless I bumped something.

I went to the tv remote and use the settings to set the Picture Size (which is 16:9) to turn on Fit to Screen to get the browser headers back on the screen and the toolbar. It was off.

I did the remote control > settings > reset picture. On the picture it displays, it is crisp and nice. Not grainy. But when I exited back to my desktop, it is all still grainy.

I used the desktop  Display Settings to confirm the Scale and Layout weren't something unusual.
100% and resolution is 1920x1080 recommended.

Tried all of the other options and still grainy.

Not sure where to go from here.

With 1000s to choose from anyone any favs and tips ?

I have an Samsung TV UE555H6200 connected via HDMI to a settop box.

Please advise.
Hello and Good Morning Everyone,

          I am wondering if there are projectors which can project an image from a USB flash drive.  In concept, it would be similar to taking an image on a transparency but instead taking it from the USB flash drive and projecting it onto the wall.  The projector would also need to have controls for shrinking and enhancing the images and well as controls for clarity of the image.   Additionally, it would be nice to have a internal rechargeable battery which will hold at least 2 hours or more of charge.  

          If what I have just described is available on the market, could someone provide a online purchase link?  If it is not too expensive, I would like to purchase one.  I have an art and painting project which can be made much easier and with greater precision if I have a digital style projector.

           Thanks in advance for any feedback given to this question.

I have seen a lot of mini projectors popping up online lately.

Can anyone recommend a good one that will work during the day (i.e - not full darkness).

I want to use it in external meetings predominantly for presentations, to save the awkward 15 mins wasted at the start of every meeting trying to connect your laptop to someone else's projector :-)
Sony Projector model VPL-PHZ10 displays a blank screen at times. It works fine with some laptops, and displays a blank page with other laptops. The 15.5" Dells seem to work OK, But smaller Dells and other brands may work OK one day, and display a blank page later the same day or the next day. These aren't obsolete laptops - they're all i5 or better usually no more than 3 years old.  We've tried both a 25' HDMI and a 10" HDMI, both Blue Rigger brand. We have no problem when we use an Airtame Wireless HDMI plugged into the same HDMI ports of the projector. I have a call into Sony Professional Support, but they say 1-2 days for a return call. I see no firmware available for download on their website, although it's possible I'm looking in the wrong place. Any suggestions that might help us keep the connection stable would be very much appreciated.

I have a HP EliteBook, which has a usb c port.

I have a HP monitor which also has a USB c port.

If I connect the laptop to the monitor to the laptop via USB c cable, I just get 'no signal'.

I purchased a HDMI to usbc adapter from Belkin, but this also just reports 'no signal'.

Any ideas anyone??!
I have multiple spreadsheets open at the same time sometimes 4-5.

I have a client that with an intermittent issue, she has 2 screens, which I am thinking is part of the problem... but she has been fine for YEARS & no issue... she actually got a NEW computer too & the issue came back??  

She has a 1"-2" WHITE Space on apps when she opens the MAXIMIZE, doesn't happen all the time, but usually she has to reboot & this fixes it, until it comes back??  When this WHITE space is on you can NOT SEE the top of the app to close or minimize or bring out of maximize... just unavailable...

I have brought down the display options to 135% norm is 100%, alot of my clients like the 125% just so everything is bigger... she wanted it a bit bigger in one of her programs & so we have been playing with that area, 150% too big, 140% is good, but the 2" white came back.

I keep thinking it is the 2nd screen maybe causing it... I really don't know, we have been back and forth alot, but the only thing that helps temporarily is reboot or changing the %... but it always comes back...

Any ideas would be appreciated??  

Thanks guys!
I upgraded to the 2019 Windows 10 update from the previous version and it changed my monitor settings so that the screen washes out.  The (HP ZR22W) monitor display was working perfectly before the update.  Every time I power on or the monitor goes to sleep I need rest the monitor back to default settings in order to have a clear display.  Even in safe mode the monitor is washed out. Any assistance to fix this would be appreciated.
