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 a 4K Sony TV monitor with a touch screen overlay on it.

A Windows PC is connected to this screen via a HDMI cable.

With this PC and display, we use Microsoft Word for brainstorming sessions where people can illustrate their ideas via the touch aspect of the Sony display overlay.

Although this solution is okay, it is not ideal.

We would like to use software created mainly for use with touchscreen drawing.

What would you recommend as the best software for touchscreen drawing?

This Sony VIAO VPCS111FM screen is DIM and does not change when using Fn+F5 or F6.

I went into Control Center and turned Automatic Brightness OFF.  No change.
BIOS is up to date.
Looked at Power Management but everything looks OK, brightness at every option is set to 100%.
Have tried turning Sony's Control Panel's Adaptive Brightness on and then off, no difference, no change.

KEY INFO, I think:  When I uninstalled the display adapter driver and told it to delete the software, the screen went black. Eventually I rebooted and the screen was BRIGHT while restarting and thru while the "don't turn off your computer" "updating ******%" messages were on screen. But just before the Welcome screen, the screen dimmed to its usual level.

When I went into BIOS, the screen was BRIGHT.  When it first starts booting, the VIAO screen is bright.  So I don't think it is a problem with the screen itself or the graphics adapter or driver.
Am thinking about doing a clean install of Win10 and scrapping all of the SONY add-ons.  But would rather fix the current installation.
So this was originally Windows 7 Pro 64-bit and upgraded a few years ago to Win10.

Please provide me with a list of the best 27" 4k Windows monitors.
A Window 10 can connect to a HP montior through HDMI. There display can be projected properly on the monitor but there is no sound come out.

Is there any potential reasons for this problem ?

On a simple office desktop - not worried about high quality graphics / redraw refresh, etc...

The new dell optiplex 3050 has DisplayPort & HDMI connectors.

The monitor has VGA (the 15 pin 3 row blue connector) and DVI (the white connector).

Thoughts on which connector to use at each end?  I would think either at each end is fine for typing word docs, speadsheets,  the occassional funny video on youtube.

I guess it comes down to the ease / cost of the cable to convert from 1 end (DisplayPort or HDMI) to (VGA or DVI).

I want to connect the iMac to additional two monitors .
So the iMac will be in the middle and one monitor on each side.

Now when I tried it , I got an error , that it's taking too much of the computer resources .

What is the est way to accomplish this?
I have two of http://www.dell.com/en-us/shop/dell-ultrasharp-38-curved-monitor-u3818dw/apd/210-amrc/monitors-monitor-accessories and trying to get them both running off a Dell XPS 15. One display is on usb c and the other HDMI but getting two different resolutions. Is there a USB to dual usb c adapter?

Seems like they dont like the HDMI
Is the Dell P2715Q monitor a 4K monitor?
What monitors when connected to a Lenovo T470 docking station (model 20HD005GUS)  will have the best and highest quality display?
Dell Optiplex 9020
2 Dell UP3214Q monitors.
Graphics cards are 2 AMD Radeon HD8490.
Each monitor plugs into one graphics card with an HDMI cable.

The problem is that whenever this computer is rebooted, only one of the monitor boots up. The other one stays dark and the power button flashes on and off.
It stays this way until the user turns the monitor off and on again.

It used to be that even this wasn't enough and the monitors needed to be unplugged and plugged back in.
Updating the BIOS fixed that.

I'm not sure how to get it so both monitors boot up though.
I already updated the graphics card drivers, BIOS, replaced the HDMI cables. What else to check? Has anyone had a similar problem?

I'm working on an optiplex 390 desktop with integrated graphics (Intel HD Graphics 2000).  It has VGA and HDMI connectors

Just got an AOC e2470swd monitor. Supposedly gets up to 1920 x 1080.  It has VGA and DVI connectors.


They are connected via VGA cable.  Going into display properties in win 10, it lists only 2 available resolution sets:
1366x768 (which it is set for now).

In there, the monitor tab says 'generic nonPNP monitor.

I got drivers from:  http://us.aoc.com/product_feature.php?id=57 but when I point the win 10 machine to the folder, it says I have the best drivers!?

Anyone be able to help me with this?

Do I need to get a DVI to HDMI cable?  Hard to get?
What's the max for VGA connectors?

Any other thoughts?
I have a 60-inch plasma television connected to my laptop's docking station (port aggregator) by way of a USB-to-HDMI converter. In the following Settings dialog, it is identified as display number 3:

I have a subscription to NBCSports.com where I use Mozilla Firefox to stream live and recorded content. So that I can watch the videos on the 60 inch screen, I select the USB to HDMI speaker for audio output…

 and then drag my browser over to the television screen (i.e., display number 3).

After logging in and selecting the video I want to watch, I get the following:

Although  I can hear the audio through the speakers connected to my computer, there is no video until I maximize the window…

I'm not sure why that is, but I can live with it. The real problem is that the audio is coming from my computer's speakers instead of the television's speakers. I'm not sure whether this is unique to the NBCSports.com site or the way in which FlashPlayer is being called, but I don't have any problems routing audio through the USB-to-HDMI connection when watching YouTube videos.

By the way, for the purposes of preparing this question, I muted the audio on the NBCSports.com tab. I use speech recognition to interact with my computer, and that was interfering with the process. Before anyone had an aha moment, I just thought I'd let you know.

While playing the video in full-screen mode on display 3, the taskbar on Display 2 looks like this:

Right now we have multiple conference rooms with the same issue: multiple cables for every type of laptop to connect to the giant HDTVs for sharing their screen.  I want to eliminate cables and find the easiest way for our employees or even our customers/vendors to come in and easily share their laptop screen onto our Samsung TVs.  What is the best solution?  Thank you.
I have recently purchased a APC Back-UPS CS 500 to support a small system. I have a new Samsung CF390 curved monitor
but for the life of me cannot see how I can connect it so it is supported by the ups.

Does anybody no if there a way as there is no point in supporting the tower if the monitor will go off.

Thanks in advance
I am looking for a 24-27" 4K non-glare touchscreen monitor. Does anyone know of any?
External Display not working well on Toshiba C850 Laptop. it flickers and keeps disconnecting frequently. Also, changes resolutions by itself.

Windows 7 32bit & Windows 10 same issue
I tested the same display with other devices and working fine.
I already updated drivers from Microsoft and AMD,

Anyone Help, please
When I go into the monitor's onscreen menu, it shows my resolution as 3840x2160, 30Hz (connected via DisplayPort).
Next to that it shows 3840x2160, 60Hz (maximum).
Based on the information I've been reading, it looks like the Mac Mini can't do anything over 3840x2160, 30Hz so that makes sense.
However, when I go into SYSTEM PREFERENCES > DISPLAYS and choose "Scaled" for the resolution, I get only the following options:
- 2560x1440 (low resolution)
- 2304x1296 (low resolution)
- 1920x1080 <- this one is marked
- 1504x846
- 1280x720
I have an abundance of cables but nothing allows me to get this thing to 4K.  Dell doesn't support Apple's OS so they don't want anything to do with it but I've been reading online that THIS monitor is supposed to be one of the recommendations online for a budget 4K monitor.
Any help would really be appreciated.
Is there a tool that can save the layout of all open programs and documents in windows before rebooting so that when windows comes back and i login everything is restored ?

I have this huge screen sitting next to me.  Is it possible to utilize it as an extra remote computer.  Remote Desktop to it and see a large design blueprints?  Need a large screen to see design documents.  I see it has an Ethernet port.
Model 1597

Got this PC and it has a HDMI port and a VGA I think.

Can it display on two different monitors?

I want to know before ordering a second monitor for it.

So the goal - one monitor connected to the HDMI
The other to the other port

Its win 10 and the end user is having difficulty doing it but it may just be him and not the capability of the PC  

> He tries to connect an additional monitor via the HDMI port to a Display adapter port on a HP screen via an adapter and it doesnt work.  Long story. Please dont ask if possible :-)

So will this PC display to two screen or not?

If all else fails I will add an additional video card - but do I need to?  

I have a Dell OptiPlex 7050 - Core i7 7700 3.6 GHz - 8 GB - 1 TB, with 2 Display Ports, and an HDMI output port as well.
(There are no VGA ports available)
When connecting the HDMI monitor to the computer for the first time and powering it on, nothing appears on the display..
The monitor has power, is plugged into the HDMI port at the back of the computer, yet no output on the screen from the computer.. just a floating message from the monitor itself.. which proves that it's working...   (The monitor only has 2 HDMI inputs and nothing else to connect to the computer).

Can anyone assist with any suggestions?
Many thanks.

I have a Dell Optiplex 980 SFF which was purchased from Amazon.  The  unit appears to be in good working order, EXCEPT for the "on-board" VGA port does not work - the unit came with a graphic card and now I know why.
> I removed the graphics card because it was running very hot and for this application that this workstation will be used, simple VGA will work just fine.
> Connecting to the on-board VGA port, there was not video during POST and after a time, I could hear Windows familiar chime when completing it's boot up.
> I started to troubleshoot.
> After having to deal with a dead CMOS Battery, I was able to configure the BIOS to use only the on-board Video (aka the VGA port) and after several attempts, the only way I can get Video at POST is with the graphics card.

So, I purchased a new(??) Optiplex 980 System Board (Which also had a dead CMOS battery, which I replaced with a new one) and low-and-behold, it TOO has a faulty VGA port.  So, now I have to ask myself...
> Am I doing something wrong?
> Is this a class issue with the Optiplex 980 SSF models?
> Was the second system Board a "used" one with the same problem?

So, I thought I would reach out to the nebulous and see if this is me or something else.

Inquiring minds need help....

Dumb question.  So I have a Lenovo ThinkPad 570 with two graphic adapters.
One Intel HD Graphics 620, and 2nd
NVIDIA GeForce 940MX.
They both show in a device manager.

When looking into the display adapters properties it shows that its using an Intel adapter.  So how exactly is the 2nd one being used?
Client purchased two new monitors for his office. One is an HP Pavilion 32q and the other is a UHD 4K 27" monitor. Both have only HDMI and displayport connections. He wants to use them in his office with computerts that only have VGA video capability. Is there an adapter that will work going from the VGA on the PC to either the HDMI or the Displayport on these monitors?

Thank you.
