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.

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.

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.
Hi Expert,

I am having a flicker issue on and off(not often) and sometimes when the pc sleep it's unable awake it, tried changing HDMI port, cable and Monitor still same.

In the event viewer, I found error: Display driver nvlddmkm stopped responding and has successfully recovered.

I did research it's due to my GPU overclocked which I didn't, need to be on Nvidia reference clocks.

I am using GeForce GTX 1080, below are the specifications  https://www.geforce.com/hardware/desktop-gpus/geforce-gtx-1080/specifications

CUDA Cores
Graphics Clock (MHz)
Processor Clock (MHz)
Graphics Performance

Strangely no issue on gaming but it happens often in video and tubing, using Windows 10 pro.

I would like to check how can I check on my current GPU clock? Is it have to download 3rd party software? Also how can I adjust to Nvidia reference clocks?

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.
Question - we just purchased a new Dell gaming PC with an NVIDIA GeForce GTX 1660 Ti 6GB video card. We have a 27" Dell Monitor as well. We have a similar PC at another office, using dual monitors. The resolution  on the first PC is 1920x1080 (which is the "recommended" resolution in Windows) at the other office with the dual monitor, the resolution is 2560x1440. Is this high resolution because of the dual monitors? The connection I have from the monitor to PC is HDMI.
I have been using f.lux now for a few years and it's been working fine.  I just got a new monitor, a 32" LG 4K computer moniotr and since then, f.lux as stopped working.
Here's the website: https://justgetflux.com

1. I have installed the drivers for the monitor
2. I have uninstalled and reinstalled f.lux at least 3 different times and restarted since then

Any suggestions what else I can do to get it to work, maybe f.lux just doesn't support 4K?
Howdy all!  I've been curious as to how i can make sure that my TCL 4K 55" tv has all of it's components and electrical pathways are as new. I would deeply appreciate it, even more, if there might be anything else that can be checked. i.e. Those free floating crystals embeded in the screen.  If you know exactly what must be done.. I'm all ears!  Or, rather, "eyes!" :D
I would like to be able to use this Magedok T1116D 1080P FHD Capacitive Touch Portable Monitor shown here http://magedok.com/touch-screen-monitor-t116c as a second monitor for my Windows 10 Microsoft Surface Go device shown here https://www.microsoft.com/en-us/p/surface-go/8V9DP4LNKNSZ/L8M8?activetab=pivot%3aoverviewtab.

I would like to be able to either go miracast (wireless) with a device like this https://www.amazon.com/gp/product/B07X7FCC1F/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 or wired. Either way would work fine with me.

I have also ordered this device https://www.amazon.com/gp/product/B07DNH2SHR/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 and I own the standard docking station that works with all the Microsoft Surface units.

I notice that the Microsoft Surface Go device has the proprietary charging port, as well as a usb-c port.

The monitor has a micro-usb port as well as a usb-c port and and mini-hdmi port.

The monitor "appears" that it can only be powered through the usb-c port, but I am not sure of that because just connecting it to the usb-c port on the surface is only enough to power it on, but does not allow the screen to display.

Assistance in figuring out the next step here is greatly appreciated.
Hi all,

I have a Samsung DB10D signage screen and like to get content on it.
I've been trying via MagicInfo Express.  When going to the final step, uploading the content to the screen, the application tells me that the screen needs to be updated.
However, when going into the update menu of the screen, it states that it's fully up-to-date.
Any ideas on how to get the screen updated to use MagicInfo Express?  (download section on the Samsung website is limited to partners)
Any other possibilities to get content on it (other application, cloud solution, ...)?

I have a KVM connected to my primary computer and secondary computer. Monitors 1 & 2 are connected to my primary computer and monitor 3 is connected to the KVM over HDMI. The problem I am having is that when I switch back to my primary computer whatever I had on monitor 3 prior to switching to my secondary computer is kicked over to monitor 1. I then have to move it back over to monitor 3. I know that when I switch to the secondary computer my primary computer loses connections to monitor 3 and this is causing the problem.

Is there a way configure the primary computer to drop the connection to monitor 3 when switching the KVM?

My new laptop is slow when using a USB docking station and external monitor.  When I first plug it in, performance is fine (no issues with control inputs or video).  However, after rebooting, the computer slows down dramatically - when I resize or drag windows, they seem to stutter across the screen, and mouse / keyboard is either laggy or stutters as well.

I tried doing a factory reset, then installing Mcafee, Updating Windows, and then updating drivers (have not installed any applications other than Chrome or Firefox) and get the same symptoms.  My hardware is pretty 'beefy' - I don't think that's the issue, but even after installing all of the drivers from Asus, Dell, and Targus, I still have these issues.

The hardware is:
1. ASUS Zenbook Pro Duo - 32 GB of RAM, I-9 processor, Nvidia RTX 2060 graphics.
2. Dell 3415W Monitor
3. Targus DSU400 USB docking station, connected via Thunderbold

Does anyone have any suggestions as to how I can try to resolve it

if i have two desktop computers, can i connect both of them AT THE SAME time into a curved monitor. so i could split screen? would this work?

thoughts on neck risks here? i am a big fan of look straight ahead and not engaging some old whiplash pain by looking left and right for prolong periods
Screw needed for this monitor arm that is less likely strip

I bought this item which came with an allen wrench to tighten up two places where the arm turns. Unfortunately, it strips out and I need to replace the screw with something more sturdy.

Suggestions are greatly appreciated.


We are current using OpManager to monitor performance and availability of all servers and network gears in our network environment including servers, switches, routers, f/w etc.

We also are using Cisco Prime to monitor Cisco gears including wireless WAPs, controllers, switches etc.

There are other tools as well, there are some overlapping scopes regarding monitoring.

We have been migrating about 70~80% of the servers into cloud (Azure and Office 365 and AWS and other 3rd party cloud service providers).

We are looking for some network monitor tools to give us 360 degree view including performance, security alerts, availability, bandwidth usage etc. Please see the following tools for consideration are just a few examples:

 MS Advanced Threat Analytics,
Network watcher etc.
Cisco Prime

Is there any product available in current market which would provide all the information as a network /system admin needs?

Any information and help would be much appreciated.

Thanks in advance.

I purchased an Onten VGA to HDMI Adapter to hopefully connect an older model ELMO TT02 that doesn't have HDMI to a Smartboard SB-6065 that doesn't have a VGA port but only Displayport and HDMI on to convert signal.  Not having any success doing this.  Instructors would prefer to not have a computer inbetween the ELMO and Smartboard if possible.  Does anybody know a possible method out there to accomplish this?
Surface book with dual external displays on surface dock maxing resolution at 1680. The screen looks horrible. I have another surface here connected the same way with one monitor that is showing 1980 just fine. I cannot figure out what this particular surface has such issues. I tried updating driver, installing all the windows updates. using only 1 monitor instead of 2. Also, when lid is open, the display allows 3000 X 2000. The second you close the lid, the resolution changes to a max 1680
We have many network monitor tools which have lots information, please see the following:
1.) Opmanage : monitor switches, servers.
2.) Exinda: monitor network traffic on different networks.
3.) Cisco Prime: monitor mainly wireless network.
4.) Cisco ISE: monitor users authentication process.
5.) Barracuda Cloud control: email alignment with SPF and DKim and DMarc  alignment
6.) PPT: report of email spam, phishing and virus.
7.) AV SIEM solution: report of abnormal/malicious network traffic detection.

We would like to consolidate all the high level graphic/charts/data info from above seven monitor systems into one system displaying on a single big screen (or two ~three screen, displaying each screen with 5~10 seconds in turn) with live dynamic updated data/info, which would be on the wall outside our IT department.

We approached Splunk for a solution 2~3 years ago, it can be done but very expensive: we talking about $200k-ish, which we would never be able to get it approved by senior MGMT.

My questions are:

1.) Has anyone done this before?
2.) What is the best approach for this consolidated high level info/data on one system?
3.) How to achieve this? and what is the cost?

Any information and help would be much appreciated.

Looking for 4k monitor options for Windows to use with Radeon card with 2 displayport.
I'm being told by a retailer that 27" is the smallest option for 4K for Windows.  Is this accurate, and what are some low-price options?
For 4K work is it better off getting a 4K capable laptop?
Monitor, maximized window blank/empty space on top of screen.
It does appear on the top or the bottom of the windows explorer or chrome or any other program. If you click / right click on this bar it seems you click / right click on the window that was active under it or the desktop is there is no other screen below.

It is not reproducible, it's not constant. Some days it happens every 5 minutes, other days it happens once.

Tried everything I can imagine with it. Getting nuts / frustrated. And our client even more so.

- changed display drivers to latest version, older version.

- reinstalled windows even with an old version of windows. With and without drivers from manufacturer or with and without windows updates.

- changed hardware (monitor and also changed vga cable)

- changed scaling. In windows, in intel drivers, monitor scaling, windows scaling, ....

- disabled fancy windows graphics settings

Everything helped for a few minutes / hours but the problems always returns.

My work 2 laptops desktop backgrounds keeps randomly turning black.  It's hurting my eyes b/c it flashes. HP says it happens when security or legal remotes in, but I checked on that and that's not happening.  I have Stardock Fences installed, too as my icon management app.  This is on Win 10 and it's up to date.
thank you,
There's been a thread of this error, but no solution applicable to my situation. (Dell XPS 8930/Win64/pro 1809

Every couple of days, particularly when using productivity apps, my screens will go black for five seconds, then come back.  In EV I get event 4101 and this: " Display driver nvlddmkm stopped responding and has successfully recovered"

This did not start until an MS tech, helping with another problem, updated me from 1803 to 1809.

My instinct was to update the display driver. I see two in DM: Intel UHD Graphics 630 and NVIDIA GeFore GTX 1060 6GB. Can't figure which one to dry to update.

Some other considerations. On 3/30 when the machine was updated to 1809, this appeared in DM Events for the NVIDiA:
And this appeared for Inter UHD Graphics 360:
Another complication: Can't find latest driver for NVIDIA on their site. Went to Dell site for drivers for my machine and was offered this with service tag:
It does not appear to be the driver listed in device manager GeFore GTX 1060. I'm guessing there might have been two options for graphics cards when the machine was purchased, but wouldn't my express service tag picked the right one? And for the life of me, I can't find a driver for the GTX 1060 on their site.

How does a Microsoft Surface tablet work? is there a white paper on how the Microsoft Surface works?
In an environment in which a desktop computer is using an Nvidia GTX 1050 video card, a Dell monitor is plugged into this card's DVI port.  From the HDMI next to the DVI port, an HDMI cable is going to an Inland HDMI 5 port splitter's HDMI In port from the HDMI outport an HDMI cable is going to an Iogear cat5 HDMI extender to two Vizio televisions.  A program titled Media Shout is installed that requires the computer to be set to Extend displays and works fine.  But for some reason if we want to Duplicate the display, the television screens go black.
I have user who keep loosin top of all applications randomly. Her Internet explorer will look like it is in full screen mode but she has not pressed F11 ( I know it as it happen in front of me. But problem is not limited to I.E , she will loos top of PDF reader, File Explorer and whatever app is opened. Resolution o both screen is same which is 1920*1080. Laptop is thinkpad L480 and the second screen is Iiyama B2483HS.
For some reason Windows+P is not working on our Windows 10 Enterprise (1809 - build 17763.253) estate.

This was a handy way to quickly switch between projectors and attached screens and people are used to using it.

Other Windows Key shortcuts are working (Win+R for instance).

This is not working on laptop or attached keyboards.  If we open Project manually from the notifications bar, then Win+P will allow you to step between the different options, but won't bring up that menu without manual intervention.

I have seen web posts about new versions of DisplaySwitch.exe maybe suppressing this behaviour (for version, see screenshot) but reverting to an old version of DisplaySwitch.exe seems to be a bit hacky and extreme.

DisplaySwitch.exe version
I don't know if this is just broken for us or if it is a general thing that Microsoft have changed for some reason.

Does anyone know if this is a universal change or just a quirk of our environment?

Is there a way to enable/disable this (via registry, GPO, InTune or something else) that might help us to get it working?
