VGA and HDMI

I am going to buy a new monitor. My firend suggested me to buy a TV instead. I have an ipad 4 and a macbook air. I also have lightning to VGA and mini display to VGA. Most of the TVs have HDMI input not VGA. I am planning to get a VGA to HDMI converter to fix it. Will it work?

Instead of getting a VGA to HDMI converter, get a Mini DisplayPort to HDMI adapter and a HDMI cable, so you don't need a converter and there are more chances to make your TV work with your MacBook Air. See > http://support.apple.com/kb/HT4241
The main benefit of using HDMI is the possibility to use a HD resolution on the TV if it allows you to use one of those

I need to connect my Imac 27'' (newest version) up to 3/4 monitors (all 40'' LCD tv's with VGA and HDMI connections) with extended display to all external screens, not duplicate images. Is this possible?

I would suggest you visit an Apple dealer, preferably an Apple Store if there's one in your city, and ask for assistance in determining what you need. The questions and issues you bring up are rather complex to address in a technical support forum and would be better addressed in person where you and the salesperson can ask questions back and forth to arrive at the optimal setup.

HT4279 I have a Macbook Pro (late 2012) and I would like to connect it to 2 screens simultaneously (1 screen is a TV and can only take HDMI, the other is a larger computer screen and has both VGA and HDMI connections). How can I do this?

The article you cited refers to The Mac Pro, a 50lb silver tower -- not a notebook computer.
Everymac.com says:
2nd Display Support:
Dual/Mirroring*
2nd Max. Resolution:
2560x1600 (x2*)
Details:
*This model supports a simultaneous maximum resolution up to 2560x1600 on two external displays via Thunderbolt. Alternately, it can support a single display up to 2560x1600 via Thunderbolt and a single display up to 1920x1200 via HDMI. Although it can theoretically power all three external displays, as confirmed by a helpful reader, it runs too hot with three displays connected.
Also see: How many external displays can the Retina Display MacBook Pro models support? What is the maximum supported resolution of each? Are adapters required?
When using other than ThunderBolt displays, the ThunderBolt port is directly compatible with Mini DisplayPort, and can be forced into compatibility (with Single-Link DVI or HDMI up to 1920 wide) with a simple adapter.
To adapt to wider displays, an ACTIVE Dual-Link adapter is needed, about US$100.

hi,
In my system multiple monitors are connected (VGA and HDMI). In need to know the

But unable to determine monitor having its corresponding values? please help me to find a solution .
is there any other method to get multi monitor details?
thank you

Hi sumith,
I read some documents about WmiMonitorConnectionParams class, it should be able to get the video putput technology by the D3DKMDT_VIDEO_OUTPUT_TECHNOLOGY enumeration.
D3DKMDT_VIDEO_OUTPUT_TECHNOLOGY enumeration
So what happens when you are using WmiMonitorConnectionParams class? What prevent you? Anyway, please see a example of using WmiMonitorConnectionParams class, maybe you could get some hints on it.

Reinstall win 7, VGA and HDMI driver

Hi everyone,
2 problems
1.I treid to reformat my hp probook 4320s and reinstall windows back to factory settings. I made a recovery disk when i first got it (at least im sure i did) and when i try to boot it says windows is loading files, i see the white bar accross the bottom moving along until 2/3rd of the way then it stops. Ive left it for 8 hours this way and it remains frozen. did i not create the disk properly?
2. So instead i had a spare win 7 and reinstalled using that, i suspect the VGA and HDMI drivers are missing or something because now when i connect an external monitor via these 2 ports nothing comes up whereas it did before i reinstalled.
Does anyone know which specific drivers i need? I looked on the support page but iv eno idea which one i need.

Hi:
Since your model can have either the Intel or AMD/Intel switchable graphics, there is no way of telling without some additional information.
Go to the device manager and click to expand the Display Adapters category.
When the graphics drivers are not installed, you will see a device labeled Standard VGA Adapter.
If you see one listing of a Standard VGA adapter, then install the Intel HD graphics driver.
If you see two listings of a Standard VGA adapter, then install the AMD graphics driver.
The AMD graphics driver will install the drivers for both the AMD and Intel switchable graphics processors.
As far as the recovery disk not working, it is anyone's guess as to why.
You can order a set of recovery disks by contacting HP for the country you live in at the link below.

VGA and HDMI DisplayPort Adapter stoped work on Mountain Lion

Hardware: MBP early 2011
With Mountain Lion 10.8.0
My HDMI adapter stoped working.
With Mountain Lion 10.8.1
Both HDMI and VGA adapter stoped working

I found a solution to this problem!
Download the driver that's mentioned at the link below and follow username "asabaraba's" instructions. It involves ditching the RaLink wireless utility and using a compatible DLink one.

VGA and HDMI Problem

Hello all,
I had my mac mini 1.83 Intel connected to my Mitzubishi 63927 via the PC connection a VGA 1920x1080 with the VGA to DVI interconnecter. I wanted to see if the quality would be better with a DVI to HDMI connecter. So I shut down my mini and switched out the cables. The resoulition was jacked! I had to scramble to the video prefrences and change the resolution to something else. 1024x768 I could see the screen. I tweaked the setting to 1920x1080 (interlased). I looked worse the the VGA connection. So I powered down and and pluged in the VGA connection back in. I computer starts up fine but there is now Video. A black screen. There are ocaisional bars of light that go across portionial to the resolution i selected in the DVI to HDMI video preferences. I loward the res in the DVI to HDMI connection sceeme tryed all variations. I VGA connection will not work. What do I do.

With the TV and mini hooked up over VGA, try starting in Safe Mode (hold down the shift key during a restart) and see if you get a useable screen that way. If you do, go into Display Preferences and select the resolution you desire (1920 x 1080). Then restart normally and hopefully that resolution will stick and you will be back to where you started when all was good.

24" TV with VGA and HDMI and speaker connection?

Bought a 24" LED TV that has VGA input. Two to three inches to wide for a monitor, but got this one because of price and the VGA input. It also has a HDMI input. Previously when doing a search for TV with PC input the results would bring up listings that did not have PC input listed in the specifications. So much for search engines.
Would I be better off using HDMI input instead?
Wide screen is nice but not so much for monitor use. Everything is stretched horizontally on monitor. Have not yet found a setting to make this wide screen not be so wide for PC usage.
The manual shows, a picture, to connect PC speakers to monitor and another cable from PC to TV. Do not even know what size the jacks should be for cable. What cable should I be looking for?
Any other advice and experiences would be appreciated.

Hi,
LED TVs are digital and the best video display is going to be using a digital signal.
The techncial specifications for the TV should inform you what digital resolutions that the TV will accept.

Projected Image size different using VGA and HDMI

From my ipad mini with a VGA connector I get a full screen image on an Epson projector but a much smaller image using an HDMI connector - How can I get a full screen with HDMI?

Good to know there are no menu's I have missed. There are 2 things between the iPad and the projector - the HDMI cable and the mini display / HDMI adapter. So as changing the HDMI cable did not help it must be the adapter. Just to add I'm pretty sure the problem first arose after i upgraded to 8.1.2

IdeaCentre K450 "no signal" with monitors (VGA and HDMI)

I purchased a K450 (from the lenovo online outlet, refurbished) in December. I got an Acer H226HQL 21.5" monitor at the same time, and set up everything at once. I used the VGA cable to connect the monitor. Everything was working perfectly until a couple weeks ago. I went to wake up the computer and the monitor remained black. I pressed the power button to turn it off completely and turn it on again, "no signal" stil on the monitor. I've tried using the HDMI cable with the acer and the 8 year old monitor from my last desktop (with VGA cable) and still no signal. Checked the power strip, it's working fine. I'm at a loss!
I did run updates on firmware for everything, including the graphics, when I set up the computer. I'd check on the firmware for the graphics card, but it's hard to without a working monitor. Also, not sure if it's relevant at all, but it was running windows 8.1.
Is there anything else I can do to fix this?
Thank you!!
Solved!

Problems like waking up from sleepmode, black screen and other problems start appear after MS released their January 2014 updates. Also timing what you say your problem began make sense to January updates. Check also this topic:

VGA and HDMI ports are next to each other; any VGA cable blocks HDMI port; want 3 displays.

The VGA & HDMI ports are right next to each other on the left side of the laptop. I ultimately would like to connect two monitors to it, but am unable to occupy both ports because the everyday end of a VGA cable/extender is too wide. Any solutions?

Hi, Firstly you won't get 3 displays without buying more hardware for your dv7 that why you won't be able to plug 2 ports at the same time. Regards.

Mini-dp to vga or hdmi, need full resolution

I've HP laptop which has two ports, VGA and HDMI.
I want to connect the Apple 27: display, which has the mini-dp output to my laptop. When I purchased the display, I bought a mini-dp to hdmi adapter, and connected the display to the adapter, and connected the adapter to the laptop using a hdmi-hdmi cable. But, the image is very blurry, and I'm not getting the max resolution on the display.
Could you someone give any advice/comments? Do I need a dual link dvi-d adapter?
Thanks!

Your laptop isn't compatible with the Apple 27" monitor. There are only two possible interfaces that can be used to drive the 27" at full resolution. One is DisplayPort and the other is Dual-link DVI, neither of which your laptop has.

VGA or HDMI on Dell U2713HM

Hi,
I just bought the Dell u2713hm that supports the 2560x1440 resolution. My laptop (with Geforce GT540M) obviously has only HDMI and VGA port. I will use the monitor only for my job, so Photoshop, Autocad and Rhino (no movies or videogames). I have 2 questions and hope you can help me:
1. HDMI imput seems to be limited to 1920x1080@60Hz, while the VGA reaches 2048x1152@60Hz. You think I have to still use HDMI or I can go for the VGA with a resolution a bit higher?
2. Is there any breakthrough (converter or settings) that let me reach the 2560x1440 resolution with my laptop?
Thanks in advance for the answers

Take a look on wikipedia.org about vga, dvi, hdmi. The biggest difference between vga and hdmi is vga is analog and hdmi is digital. Dvi on the other hand is both and there is an adapter for vga/dvi and one for dvi/hdmi. As quite a few of the older computer only had a dvi connector.
When I looked at wikipedia about vga, I was actually shocked that the resolution went that high. I just assumed it could not handle the extra bandwidth. But I was wrong.
At this point in time there are very few monitors that are capable of going higher than 1080p. But that is changing ever sense Apple came out with their retina displays.
I just checked on Apple's website and it looks like the retina display is 2560-by-1440 and the Sharp 4K monitor is 3840 by 2160. I don't know whats available in the window or linux market for anything higher than 1080p. But I am sure they will follow suit.

Best Connection VGA or HDMI???

Ok people...i have read all these stories about plugging in DVI to HDMI on LCD's but my question is which connection is the best?? I have a Vizio 32in LCD with both VGA and HDMI. I'm currently using the VGA setup and it automatically went to 1366 x 768 when i first hooked it up. Will i get better resolution off of the DVI to HDMI connection? I'm trying to find the best connection for my mini with the best picture quality. any suggestions is greatly appreciated...

The answer to your question depends a lot on the TV. In a perfect world, the digital HDMI interface would be the superior one. But in practice, a lot of TVs designate VGA as the port of choice for a computer connection and don't correctly handle computer input over the HDMI interface.
The two most typical problems with connecting over HDMI are that native resolution of the panel isn't realized and the other problem is that an overscanned condition is forced by the TV's processor causing the edges of the desktop to be off the screen and out of view, as though they are under the TV's bezel.
You'll just have to try. If HDMI also results in 1366 x 768 and no overscan, then go for it.

I have a Mini DisplayPort to VGA adapter, then I purchased 3 VGA adapters: a VGA to HDMI, VGA to Component, and VGA to RCA. When I hook them up to my TV (I've tried multiple TVs) they do not detect a display, even when I click Detect Displays.

Does anyone have any suggestions on a solution for this? The only other Mini DP I found was a HDMI connection. I want to make sure I can connect to not only TV's via HDMI, Component or RCA, but also projectors (some of which may be older requiring a Component or RCA connection).
I'm using this Mini DisplayPort:

Any help would be greatly appreciated.

None of the three lower adapters pictured in your post will do you any good with your MBP.
1. The VGA-HDMI adapter does the reverse of what you want: it yields VGA output from HDMI input. The opposite is not possible; a VGA input does not contain all the information necessary to create an HDMI output. You'll have to get a direct mini-Displayport-to-HDMI adapter instead.
http://store.apple.com/us/product/H1824ZM/A/Moshi_Mini_DisplayPort_to_HDMI_Adapt er?mco=MTY3ODQ5OTY
2. VGA-Component: Lots of posters here when the MDP-equipped MBs and MBPs first came out tried adapters like this one with no success. What does work with the MDP (and a VGA adapter) is a converter box like this:
http://www.amazon.com/Startech-Component-YPbPr-Video-Converter/dp/B000G6Y0S6
3. VGA-Composite: This doesn't work with MBPs either. For Composite or S-Video output, you need a converter box like this:
http://www.amazon.com/PC-To-TV-Video-Converter/dp/B001CJOLBW/ref=pd_cp_e_2
or this:
http://www.startech.com/AV/Converters/Video/High-Resolution-PC-VGA-to-TV-Convert er-with-Remote-Control~VGA2NTSCPRO
These converter boxes will work fine in combination with your Apple MDP-VGA adapter.
