New Card Needed

[James T]

Hi guys, first post so please be gentle.

Just getting my PC sorted which i will be running some video software through mainly (Sony Vegas), and running 2 displays. I did have a Geforce 7900 GTX Graphics Card (1024) installed, but when i plugged in my new 2nd monitor in to it this morning i got a blue tinted screen. Swapped monitors round and confirmed it was the card. So run down the local shop to buy a new card and all is good once again. BUT... my picture is now every so slightly vibrating and i know will really annoy me sooner or later.

So my question is... is the vibration down to this new GC? And if so can anyone recommend a similar card that will do me good??

The new card i have just put in is a 512 nVidia 9500GT.

Normally a vibrating or unstable picture comes down to a loose cable, in my experiences anyhow. It could also be a bad monitor. Try reconfiguring them through the Properties menu on the desktop. You can get special programs to configure dual screens, but I'm unaware of any.

I'm not so experienced with dual-screening, so give me some space to think!

Oh, and welcome to OC3D

Thanks for the reply. I've checked and double checked the cables and they seem to be securley connected. it's very odd as the original screen was perfect last night with the old GC, and the only new thing since then is the GC. But could just be a coincidence i guess.

TBH mate, the only thing I could offer is blind advice, as I have zilch experience configuring dual screens.

There's nothing on Google specific to both the 9500GT and dual monitors, so I can't jump to the conclusion that the fault is your graphics card.

Try following this small guide I found, I think its pretty much what you've already done, but it might offer a little bit of advice at least.

1. Attach the external device (monitor / projector) and turn it on. Make sure the cables are correctly plugged.

2. Right-click on the desktop and choose Properties.

3. Choose Settings.

4. You will see two displays, labelled as 1 and 2.

5. The numbers 1 and 2 indicate primary and secondary display. Display 2 is initially on the right side of Display 1. (This is an important observation. We will discuss this later)

6. Now click on the boxes 1 and 2 and observe that the resolution and colour slider below may change. This is because you can set the resolution of each display independently of each other.

7. It is important to understand that each type of monitor / projector has a limitation about the maximum resolution it can display. Most monitors nowadays are plug-and-play. This means, once the external display is attached to the PC, the operating system can automatically understand the maximum permissible resolution limit of the external display.

8. Now right-click on Display 2 and choose Attached.

9. This selection enables some additional check boxes on the dialog.

10. Now choose the “Extend my Windows desktop onto this monitor” option.

11. Choose Apply.

12. Now the second display will be enabled and will display a blank desktop. This is an additional desktop for you. It is not a copy of the base desktop. The appearance of the second desktop will depend upon the primary desktop configuration.

13. That’s it. You just configured a dual monitor display!

14. To prove that it works, move the mouse to the right edge of the primary desktop screen. Usually, the cursor would stop at the edge. However, now it simply spills over to the new, additional desktop. This desktop is empty by default.

Slight vibration is usually the frequency of the screen output.

If it is, u can goto the nVidia control panel, goto the changing of resolution section, and u'll notice there will be options for resfresh rates for the output. Nominally 60/66/75/8/100.

These 'should' be frequencies ur tv/monitor can accept in terms of what it reported back to the pc after being plugged in, so all of them should be selectable.

+1 first moment I read the shakey screen etc.. I thought refresh rates double check if their to the manufacturers specs

I haven't experienced much in 9500GT, have you checked your driver? I highly recommend to get the latest one.. (I won't suspect the monitors are the problem, coz it worked fine with the 7900, right?)

I don't know the specs of your displays, but if the problem comes from an "underpowered" cards, I'd suggest to get a better card, 9600GT or Radeon 4830 (bang for buck cards) should work fine (I've seen a friend of mine using dual-LCD monitor with resolution 2x 1440x900) for video-editing or gaming.
