Solved Problems with my new monitor.

October 21, 2011 at 08:15:46
Specs: Windows 7, i7 2600 @ 3.4GhZ / 8168 MB
Today I bought a S24A300BL 24” LED monitor, on the back of it, it had both DVI and VGA ports. Since my old monitor had only VGA port and my video card ( ATI Radeon HD 6850) had only DVI port, I had to buy this "thingy" which changed one of the ends of cable (both ends were VGA like) to DVI, so I'd plug it in my PC. And it worked fine.
Yet now, this new monitor, I connected it the same way I did with my old one.. VGA end of the cable in my new monitor, other end via that "changing thingy" into my PC. ( DVI port)
Now it only displays, " Check Signal Cable " and bellow it " Digital "

Oh and regarding installing right drivers, it's making me chose like "analog" or "digital" at the end of installing drivers, tried both, non worked.

My only guess is that I need a cable with both DVI ends.

If You can help, I'd greatly appreciate it.

The "thingy" is a gender adapter - a standard DVI male to VGA female gender adapter. It will allow you to produce video on a VGA connected monitor ONLY when BOTH the video card and the monitor supports the DVI-I standard.

I'm assuming you have only the one gender adapter that worked with the previous monitor
Your HD 6850 video card DOES support the DVI-I standard (analog - VGA - and digital video) , but apparently some newer monitors only support the DVD-D standard (digital video only). You must either plug in a VGA connected monitor into a VGA port on the video adapter, or use a DVI to DVI connection.

I found no support on the Samsung web site for S24A300BL, but I did find this for S24A300B :

Samsung S24A300B User manual

..which shows at the beginning of it that it is also for S24A300BL.

There is no mention in it of being able to use a gender adapter with a VGA connection to connect to a DVI port on a video adapter, so it appears you must use a DVI to DVI cable with it, which it and probably your model apparently does not come with.

Page 15 - zoom in to see the DVI port better

Go here
Digital Visual Interface

Scroll down to Connectors

- the DVI port on the monitor is DVI-D (Dual Link)
You must use a cable with a DVD-D (Dual Link) connector on at least the monitor end with it.

- the DVI port on the HD 6850 video card is probably DVI-I (Dual Link)
A DVD-D (Dual Link) connector (male) can be used with it (female) but a DVI-I connector (male) cannot be used with a DVI-D video port (female).

Manuals for older monitor models DO often mention using a DVI to VGA gender adapter if you require one to use a VGA connected monitor with a DVI-I port on a video adapter

All video cards - that you install in a mboard slot - that I know of that have a DVI port that supports the DVI-I standard. They often come with a standard DVI to VGA gender adapter.

Some onboard video adapters - that are built into the mbord - that have a DVI port that supports only the DVI-D standard - they can't be used to produce video on a VGA connected monitor when you use a standard DVI to VGA gender adapter,

I'm assuming that you plugged the monitor into the video port BEFORE you started up the computer. You can DAMAGE the monitor and/or the video port circuits on the video adapter if you plug it in while the computer is running.

If your computer has both (a) video port(s) for onboard video and a video card in a mboard slot, usually the onboard video port(s) will NOT produce video when the video card is plugged in.

"Oh and regarding installing right drivers, it's making me chose like "analog" or "digital" at the end of installing drivers, tried both, non worked."

Monitors DO NOT require drivers to be installed on the hard drive in order to produce video BEFORE the operating sysytem loads while booting, or after the operating system loads - the monitor, mboard bios, video adapter, and Windows have built in support for displaying basic video.

Monitors with both a VGA and DVI port or integral cable can be used for one or the other type of connection at a time, not both.

You install video drivers for the monitor for the type of connection you're using so that, by default, Windows will only show you settings that the type of connection supports that will not damage your monitor if you use them.

When you install drivers for a monitor from a CD that came with it, or by running a download you got from the maker's web site, Windows may not be actually using them - you may also need to select them in Windows.
In Windows 7 or Vista, RIGHT click on a blank part of your main desktop screen, select Personalize, then Display Settings.
If Windows is using the proper monitor drivers it will say there Samsung xxxx on HD 6850 or similar.
If it says Generic PnP monitor on HD 6850 or similar, you need to select the proper drivers.

I'm going to disagree with the last post. If you are able to plug in a vga to dvi adapter, then it should work fine. On the dvi side of the adapter you will see 4 prongs surrounding a larger prong on one side. The larger prong is the digital, and the smaller 4 prongs are the analog. If a piece of equipment does not support analog, you can not even plug this into it as the female part on the monitor, video card, etc. will not even have holes for these 4 prongs. Check the manual to see if you are able to switch your monitor from digital input to analog input.

If builders built buildings like programmers wrote programs, then the first woodpecker that came along would destroy civilization.

Since your video card and monitor supports DVI digital signal and the digital signal is definitely better, just go out and get the DVI cord. That way if the monitor still does not work, you can return it. IF the store you are going to is where you purchased the monitor, take it with you (especially if it is a long trip) and have them test it on their computer with your new DVI cable so you are sure that all should work when you get home.

You have to be a little bit crazy to keep you from going insane.

The DVI cable has to be a DVI-D cable, not a DVI-I cable, because the DVD port on the monitor is DVI-D (Dual Link).
(A DVI-D male connector on at least the monitor end of the cable; a DVI-I male connector won't physically plug into the port on the monitor.)
