how to ? dual monitors

steviestar · Apr 18, 2014

I have a vga and dvi-d ports on the back of my graphics card.i have the same on 2 monitors . the guy in the shop said i can run 2 monitors off this . The vga works fine on both monitors but the dvi-d with a dedicated cable (new ) dvi-d to dvi-d is just showing a blank screen. i have tried downloading the latest drivers and rebooting the computer like ive seen in another post but still nothing . any ideas anyone

what inputs are on both monitors does the one with dedicated dvi have any other inputs ?

mickypheonix :

hi both have vga and dvi-d. one monitor is 10 metres away and is using a vga to vga cable and the port on my computer .the one that is left is the dvi-d port and ive tried the dvi-d cable to the monitor in front of me , nothing

mickypheonix · Apr 18, 2014

have you tried the vga cable on the other monitor just to see if it is working ok ?

steviestar · Apr 18, 2014

mickypheonix :

yes both monitors work with the vga cable

mickypheonix · Apr 18, 2014

perhaps there is a damaged pin on the dedicated cable or the cable is faulty , any possibility to try vga on both at same time ?

mickypheonix :

no , there is only one vga and one dvi-d on back of computer . dont think is cable its new . ive also tried dvi-d to vga conerter that doesnt work either.

Do you need to tell the monitor to use the dvi port?

mickypheonix · Apr 18, 2014

4745454b has a good point , some monitors will automatically pick up the video signal whilst some you have to manually select the incoming signal

yeah i have tried going to control panel typing in monitors and it gives the option of multiple monitors but wasnt picking up the second one .

4745454b · Apr 18, 2014

If it's not seeing the second one that might be your problem. What GPU are we dealing with?

steviestar · Apr 18, 2014

amd 2 x4 965 processor 3.40ghz

4745454b · Apr 18, 2014

No, GPU. What video card is it?

steviestar · Apr 18, 2014

amd radeon hd 5450

4745454b · Apr 18, 2014

Should work. Can the DVI port work if the VGA is unplugged? Did you try switching the monitor from VGA to DVI input?

steviestar · Apr 18, 2014

i have tried the dvi-d cable on its own with one monitor and it doesnt work. the monitor has a sticker on it saying dual analog and dvi inputs so i know this is ok to use dvi-d with . the computor has recently had the above mentioned graphics card put in and i was told i could use 2 monitors with it . is there some other setting in my computer i should be changing /adjusting ?

4745454b · Apr 18, 2014

Maybe not. What's the monitor model number?

steviestar · Apr 18, 2014

gateway FPD 1960 TFT LCD

Reading the review on your monitor it does support a digital connection. (I was wondering if you had a DVI-A port on the monitor because you said "the monitor has a sticker on it saying dual analog".) So this leaves the following options. 1) the DVI port on your GPU is bad/dead. 2) The DVI cable you are using is bad/dead. 3) You still haven't tried/done correctly the switch on the side of the monitor to switch from VGA to DVI.

The FPD1960 accepts analog and digital input, and the top button on the side allows you to switch between the two sources.

If you did the button already, I'd try another cable. If that still doesn't work that only thing that comes to my mind is the DVI port on the card is dead.

cheers that sounds feasible, i have tried the button on the side of the monitor it goes black comes back on and says "input analog". so i try the dvi-d cable (its definitely dvi-d on the monitor)All goes black cos no signal i press button again on monitor thinking its gonna appear saying now digital but nothing .

steviestar · Apr 18, 2014

i will trycable next , but its brand new from tesco is it possible its that .

4745454b · Apr 18, 2014

Is the card new or used? If cable is new and card is used, I suspect bad card/port.

Kekoh · Apr 18, 2014

I've heard of people having similar issues that were caused by using 1 digital signal and 1 analog signal together. After they switched to both digital signals their second monitor started working. I haven't seen this personally so I don't know if i's true.

steviestar · Apr 18, 2014

it was supposed to be new , but ive had stuff from this shop before and found its been used, so im suspecting the shop now myself , dam.wont know till tomorrow now ,if they are open and they can do it then . thanks for your help, will let you know what happens , your probably right .
