Personally I use my HDMI monitor as my main monitor and have the secondary monitor attatched to VGA. I can't really tell the difference in performance between the two, however I never work with anything terribly graphics intensive.
and it hurts to hear that my Samsung 22" is also 'aging' of course so is my 17" secondary I guess maybe that'll be my next investment...
Sorry about the aging comment
But this is the answer I was looking for! I don't want to have 1 monitor hooked up via HDMI and the other VGA and be able to see a noticeable difference between the 2. I don't do anything graphics intensive either.
Thanks for all the responses!

Can't see dual monitor via HDMI on Lenovo U310

Hi All.
I try to connect second monitor (NEC MultiSync EA232WMi) via DisplayPort to my Lenovo U310 HDMI port and it didn't work. The only I can see is a black screen on NEC and nothing more. I tried Fn+F10 to select output mode and standard Windows 7 resolution settings.
Maybe I should use HDMI-DVI instead of HDMI-DisplayPort cable or need to install additional drivers?
Can anybody help with it?
Thanks in advance!

Solved this problem by using HDMI -> DVI cable connection.

Dual monitors with HDMI Splitter

I am wanting to use my ATV 2 at work to run a slideshow on 2 monitors. I bought an HDMI Splitter but it just has a black screen. If I hook up 1 HDMI it works fine. Any ideas?

It sounds like you are trying to use a passive splitter, which means when two displays are connected at the same time the Apple TV will be trying to talk to two devices at once causing corruption. You might try powering on one device at a time but my suspicion is it still won't work and even if it does you may well experience a degraded signal.
You probably require a multiplexer which is somewhat more expensive.

MiniDisplay to HDMI : How to turn off the Dual Monitor output when..

miniDisplay to HDMI : How to turn off the Dual Monitor output when the adapter is attached and the TV is off ? And will keeping the adapter connected even if it is not in use, cause damage to the adapter ?

I have my external monitor/tv setup of the left. If I leave the adapter attached with the TV off, I am still able to cross the border/boundry of my MBP screen ! As instead of detecting a TV, the MBP is detecting the adapter as a screen. I do not want to damage my thunderbolt/miniDisplay port by plugging and unpluggin the unit each and every time.

Dell Inspiron 7000 series dual monitor issue

Today tried to connect Dell Inspiron 7437 to external monitor using HDMI cord; it did not work. I changed setting to external monitor only and now cannot get an image on laptop screen or external monitor when HDMI cord is connected. Tried to restart computer; still goes to blank screen as soon as I plug in HDMI.
1. How to a return to default setting for laptop display so it's only set to laptop?
2. Is it possible to connect inspiron 7000 to external monitor with hdmi?
Thank you

Hello,
Yes, it is possible to connect the Inspiron 7000 series to an external monitor using an HDMI cable. Normally you can control how the video is displayed by using the <FN>+<F8> key combination. Normally your options are LCD only, duplicate display on the LCD & the external monitor, or just display on the external monitor (projector mode). Try that key combination to see if you can toggle between the available displays.
One thing you also might want to check to see is if that monitor is set to a resolution that your system cannot handle. Here is a link to the product support pages for the Inspiron 7437, and you will find user manuals on the page that will help explain which resolutions your video card can handle. You may need to set your monitor back to default settings (see your user manual for that monitor for details) and that should enable your system to send video to it.
Let me know if any of this helps or if you have additional questions.

Considering buying a Mac Mini but I need to know about support for dual monitors using DVI connectors.

I have a couple of DVI monitors and I'm looking to replace my Windows desktop with a Mac Mini. I found an article that says it supports dual monitors with Thunderbolt, but I can't find any discussion of using it with existing monitor, or running multiple DVI displays off a single Thunderbolt port.
Has anyone done this? If so, what's the best way to achieve it?

Yes, the Mac Mini has both an HDMI and Thunderbolt/MiniDisplay Port and supports dual displays in either Mirroring or Extended Desktop Mode.
It ships with an HDMI to DVI adapter that you can use for one DVI Display.
For the second DVI display you will need to buy a > Mini DisplayPort to DVI Adapter and plug that into the Thunderbolt/MiniDisplay Port.

How do I set-up my TV as a dual monitor for my MacBook Pro?

Hi
I have a mid-2009 MacBook Pro running (OS X 10.8.2) Mountain Lion, and recently I rearranged my home workspace so that I can view my TV from my desk while I work.
I would like to set-up my TV as a dual monitor for my MacBook Pro, so I can stream videos on my TV screen and have the whole screen to do work on my MacBook Pro at the same time.
Is this possible? I've seen people use TVs as a mirror display (where it works as their main and only monitor), but never as a fully operational dual display.
As an example, I would like to have my MacBook screen showing a desktop with the whole screen devoted to Photoshop, while I have another desktop running on my TV, which shows an internet browser or other application.
If this is possible, what cords/hardware would I need, and what are the settings that will enable me to do this?
- My TV is a modern flatscreen LCD, and it has two HDMI ports in the back.
- It's about 9-10 feet from my desk.
If anyone could help, that'd be awesome!
Thanks.

Yes, you can do that.
You'll need a mini displayport to HDMI adaptor:
http://store.apple.com/us/product/H1824ZM/A/moshi-mini-dp-to-hdmi-adapter-with-a udio-support
and an HDMI cable long enough to reach your TV
(look on Amazon or Monoprice for the best price on any of those parts)
In your display options, you will just choose extended desktop vs mirrored display.

Sorry no, this one > Mini DisplayPort to DVI Adapter - Apple Store (U.S.) plugged into the combination Thunderbolt/Mini Display port and then a DVI-D cable to the monitor.

Dual Monitor Support

Not sure if this one can be anwsered yet, but curious to know if there is a way to hook up dual monitors on the new Mac Pro cylinders? I don't mean just mirroring either. I have worked with dual monitors for a very longtime. One I use for my workspace and the other I use for tool palettes. I see that there is only one HDMI port on the new computers and I use DVI monitors. I really don't want to have to buy new monitors if I get one of these.

DVI can be converted to/from HDMI with a simple "all wires" adapter or cable.
Mini DisplayPort can fall back to DVI mode by asserting a control lead on the Interface, so another simple adapter.
ThunderBolt display mode is fully compatible with Mini DisplayPort.
So with the right adapters, you should be able to get six displays working.

Dual Monitor with iMac?

I have a iMac from early 2009 and wanted to use it as an external monitor for my laptop which has Windows 8.1 as it's OS. So my question is without using any software such as Synergy, Air Display, etc is there anyway I can make the iMac an external monitor for my laptop. I also have boot camp set up with Windows 7 as it's OS and I'm not sure if that's any help or not making this dual monitor setup work.
I was going to buy a mini displayport to VGA adapter (iMac (Early 2009) - Technical Specifications says: "Mini DisplayPort output port with support for DVI, VGA, and dual-link DVI via adapter," so I am assuming I cannot use HDMI) and use that to connect my laptop and the iMac together. And so I was wondering if that'll work out if I'm on windows partition in boot camp or not.

Any help would be appreciated, thanks.

Can't do it as far as I know. The mini display port on your Mac is for output only. You need a late 2009 or later iMac to do Target Display Mode Target Display Mode: Frequently Asked Questions (FAQ)

Dual Monitor Audio Setup?

Hi there!
Getting my new Mac Mini next week.
Question about setup - dual monitor and audio.
I will be connecting to my TV via DVI - HDMI and monitor via MDP - HDMI.
What are my best options for audio?
Monitor doesn't have speakers so I was thinking of using my current 2.1 system with a 3.5mm jack. I know I can use a splitter from the 3.5mm port on the Mini for analogue sound but is there any way of outputting digital audio to the TV and analogue to my speakers.
On my PC audio is carried to the TV via HDMI so auto switches audio when TV is detected, can the Mini do similar?
Cheers

Welcome to the Apple Discussions!
1. The mini's m-DVI and m-DP do not carry audio.
2. Switching from analog to digital audio is a mechanical process that occurs in the audio mini-port. The digital mini-plug is about 2 mm longer than the analog plug and effects the change.
3. You might consider using the audio port as the source of digital audio for your TV and get a USB adapter for analog audio for your speakers.
4. You can add the digital audio to the HDMI stream with this device;

Dual Monitor Setup S5-1070t

I am trying to connect a second monitor to my HP S5-1070t desktop It has an AMD Radeon HD 6450 graphics card installed which was ordered with the computer. This card has a DVI and an HDMI port on it. My main monitor is an HP 2011x connected to the DVI port on the card. I am attempting to connect a Compaq Q1859 monitor to the HDMI port using an HDMI to VGA adapter. I updated the AMD Calalyst Control Center to Version 2013.0328.2218.38225. When I run Detect Displays it only shows my HP2011x display.
I scanned through the previous dual monitor questions but I didn't find anything related to my problem.
Any help would be appreciated.

Here are the original specs and configurable options for your HP Pavilion Slimline s5-1070t CTO Desktop Computer. Here are the specs for your HP Pavilion 2011x WLED backlit monitor and your Compaq Q1859 Widescreen LCD monitor. According to the specs, the 2011x monitor supports both DVI-D and VGA video input connectors, while the Q1859 only supports a VGA video input connector.
You stated the s5-1070t with HD 6450 graphics card supports both HDMI and DVI video outputs but you didn't indicate which type of DVI it is. DVI comes in DVI-I (both analog and digital), DVI-A (analog only), and DVI-D (digital only). Please review this Wikipedia DVI article to determine which type is on your card or post a photo of the ports on the card.
You also indicate you are using a HDMI-to-VGA adapter. There is no way way to "adapt" a digital HDMI signal into an analog VGA signal short of using an expensive digital-to-analog converter. These converters normallly run in the hundreds of dollars and don't always produce good results. Until the monitors are correctly connected without this "so-called" adapter, the computer is only going acknowledge one monitor.
If, and only if, the Radeon HD 6450 supports HDMI and DVI-I, you can connect both monitors as follows and both monitors will work;
Computer ---> HDMI-to-DVI-D (digital) cable ---> HP 2011x Monitor
Computer ---> DVI-to-VGA dongle ----> VGA cable ---> Compaq Q1859 Monitor

Win 8.1 not remembering dual monitor setup after reboot

Hello,
I am running Windows 8.1 64-bit Enterprise N with the following hardware:
HP ENVY TouchSmart 4-1245tu Sleekbook with Intel HD 4000 Graphics
Dell Monitor
HDMI Out from laptop to VBGA In on monitor (HDMI to VGA Convertor used to connect with second monitor).
I have setup multiple monitors and it works fine. However once I do a reboot on the laptop the machine, after reboot only laptop screen is detected and second monitor/external monitor not detected ( it is blank with the External monitor having its backlight on (so its not in standby) but nothing is being sent to it.)
It looks as if Windows 8.1 is not remembering the extend monitor setup after a reboot.
I am running the latest drivers from Intel for Windows 8.1 64 bit and Intel 4000 graphics:
Release Version: Production Version
Driver Version: 15.33.5.64.3316
Package: 209756

Any ideas?

I have the same problem with HP8300 Elite CMT
Dual monitor works fine after reinstalling the video drivers.
When I restart the PC the second monitor is not found and the drivers have to be reinstalled.
I have opened a support case

Dual Monitors on Mac Mini Late 2014 not working on Dell S2340Lc

Hey guys,
Got a mac mini and using it mainly for work. Working for an ISP and no one has used macs and I've opted to be the poor sucker that gets to deal with old people that don't know how to mac very goodly.
I have two Dell S2340Lc monitors. I have one connected up via HDMI and that works perfectly fine. I turned off the mac, I plugged in Monitor 2 with a MiniDP/Thunderbolt to HDMI adapter, powered on the mac and whilst it was booting, it had the Apple logo and the loading bar on the Dell display plugged in to the thunderbolt to hdmi adapter and then once it loaded up the log in screen, it went to the HDMI display. I logged in and in the displays section, the monitor plugged in to the thunderbolt to hdmi adapter isn't being detected, however I can plug it in to a Samsung 55 Inch Smart TV and it works just fine. I can set up dual monitors between the TV and the monitor in HDMI, but the Dell S2340Lc will only work with a HDMI cable into the HDMI port on the mac mini and will not work through the thunderbolt to hdmi adapter. On the display it just says that there is no signal coming from the computer.
Just wondering if any of you apple gurus had any ideas as to why this isn't working?
Thanks!

Dual monitor connection for ATI Radeon 4350

I have HP Pavilion Elite e9300z PC with 512MB ATI Radeon HD 4350 [DVI, HDMI, VGA adaptor]... I want to connect a 2nd monitor to video card. I think my current monitor is HDMI, so for the other (DVI) is it dual-link? In other words, should I get a dual-link DVI cable or a regular DVI-D cable? Thanks.

Regular DVI-D cable shoould work, your monitor must have a DVI-D and not a DVI-I port...
