Hello, I have two LG W2243S monitors, and Ati RADEON HD 4650.

I have tried them to work as dual monitors, in 3 OS.

Windows 7 32 bit and 64 bit, and WIndows 8.

Always the same problem...I try to work with resolution 192*1080 in both monitors.

The first is ok at 59 Hz. The second gives me the choise to work till 1600*1200, but it does not go under 60HZ.

What is wrong? My card does not support the dual monitors in high resolution?

Thanks

Hello manin,

 

Can I ask what you are trying to achieve by running a dual monitor set up in high res, gaming or watching videos etc.

 

The reason that I ask is because the HD 4650 was only an entry level card capable of playing some games on reasonable settings and on a single screen, the dual monitor option was better suited to using two screens in a HTPC set up, also keep in mind that if your card is the 512MB version it will perform worse than the 1GB version + the better your other hardware the better the video card will perform.

 

Have you tried alternating which video ports the screens are connected to.

Hello, thanks for your answer.

 

The reason for having two monitors, is work. Lower res did not work for me.

My card has 512 MB memory.

So you believe that my problem is my card?  What must I have in mind choosing the next card?

It's memory?

 

I have two VGA monitors, so my options to your last question are limited...

I use VGA port and DVI port with an adapter

 

Thanks for your time

Hello manin,

 

Before saying that the card is at fault we need a little more info;

 

Can I ask what type of work it is, office work such as spreadsheets for example, this to see what sort of demand is being placed on the card.

I use VGA port and DVI port with an adapter

 

 

You should try swapping the DVI adaptor to the other VGA cable to see if that makes a difference, the card could be fine and the problem lay with either the DVI adaptor, the video cable or the screen itself.

 

Can you post the processor, Ram (amount and speed) and the PSU details for us

 

You are welcome btw

I work with TIA PORTAL. I have done the swap through card ports but no luck...
I have this pc 4 years now...I tried in the past with dual monitors, but it worked only for a short time, and then problems came up.
Problems as I have described above...
 
Now the strange thing....This morning, the second monitor gave me the option for 1920*1080 res and 59Hz, so I work just fine now...
I don't know why and what it has changed, and how long it will last

That is odd behaviour for sure but for me if the settings remain I will be happy for you 

 

Looking at your other hardware I would suggest a video card upgrade in any event, for dual displays you would benefit from having 2GB of VRam and a minimum of 128 - bits, 256 bit would be better if you watch videos or do any gaming.

 

Your Speccy log does not tell us your PSU details, can you let us know the brand and model name or number.

Not heard from you for a while manin, do you still require assistance or is the issue now resolved, an update would be appreciated.

Sorry for not responding...

My problem is not solved entirely...

From times to times, I have problems, but I solve them quickly...

It is obvious that I need a better graphics card

[manin]

I updated my machine with Nvidia Geforce GT 730 and new power supply...

The new with dual monitors is what you see in the video.

 

I start Trading STation application, and when it goes to full monitor the monitor goes to power saving mode...

It turns to normal only if I bring desktop in front

In one monitor I use a VGA to DVI converter. I believe that this is the trouble maker this time...
