HD5450 Triple Monitor Support Problem

[Mundle101]

I recently upgraded my Graphics Card to a Radeon HD 5450 with Triple monitor support,
it has 3 outputs 1-DVI ,,1-VGA,, 1-Display port hooked up to 3 monitors, 2 samsung 19" wide screens and a I-INC 25" widescreen... Currently i have the 25" in the middle with a 19" on either side,, The Problem is when i go to extend the desktop in the Appearance box, and click apply i get a error ( Unable to save Display settings ) it will let me use that monitor i couldn't extend only if i disable another display first (IE: my main monitor) all the drivers for monitors and card is up to date,,

25" plugged in with a Display Port to HDMI adapter
19" plugged in with a Standard VGA cable
19" plugged in with a DVI cable

AND I'm about to pull my hair out on this, any input would be greatly Appreciated.

What I would do first is clear out the multiple-monitor setting by switching to just one monitor, restarting that way, and re-apply the desktop extension.

When you click "Detect" does it give you all three screens to work with, at least?

 

[Mundle101]

Yes it shows the 3rd monitor when i hit detect,, I will try to restart with just the one monitor and attach one at a time to see if it works

Thanks

If the Display Port adapter is not of the "Active" variety you'll never get all three working. Is your adapter on this list?

AMD Eyefinity Validated Dongles

Yea i think that's the problem, the display port i have is DP-HDMI i got off Amazon for like 20$ and it works fine as I'm using it now with a dual monitor configuration, so i need to get the right dongle to use all 3?,, as i understand it u need to have a passive DP configuration for using more than 2 monitors on the same card

 

[profdlp]

...so i need to get the right dongle to use all 3?...

Yes.

...as i understand it u need to have a passive DP configuration for using more than 2 monitors on the same card

Exactly backwards. Passive Display Port works with one or two monitors. The only way to get the third working is with the Active dongle.

If I sound very sure of myself it's because I bought a new XFX 6870 and a third monitor two days ago. The box for the video card said it had two Display Port connectors, so I bought an AMD-Certified DP-to-DVI dongle. Unfortunately, the Display Ports on the card are of the Mini Display Port variety and my dongle was the regular type. No one seems to stock such a critter as the Mini DP-to-DVI locally so I took a chance on a passive dongle. Everything I had read told me it wouldn't work - and it didn't. I had the same result as you: I could get any two monitors I wanted to work, just not all three at the same time.

I almost jammed my 4870 card back in there out of frustration, but my PSU would be pushing its luck with two video cards in it. I ended up ordering one of these from Amazon:

Now I'm just waiting for it to be delivered...

EDIT: See Post #4 for the link to AMD/ATI certified dongles if you don't want to get the one linked above.

Let us know if it works!

Let us know if it works!

Definitely do that - this thread will almost certainly be helpful to someone else, too.

Helpful to me. I got a graphics card with DP today and didn't know about active/passive dongles.

 

[profdlp]

Got it from UPS today!

One moment of mild panic when I plugged it in. Windows detected the new monitor but the screen was blank. Went to display settings, enabled it, and:

It's 3-Monitor PARTY TIME!!!

(Using the one I linked to in POST #6)

A couple of more for those in the US at least (or what to look for elsewhere) that should work with any HD 5xxx or HD 6xxx series card regardless of who made it,

Newegg.com - SAPPHIRE Active DisplayPort Adapter 100924 DisplayPort to DVI Interface

ir if your card has the mini port,

Newegg.com - POWERCOLOR Video Adapter ACTIVE MDP TO SL DVI-D ADAPTER-C Mini DisplayPort to DVI Interface

Nice links, stormy13.

It might be worth mentioning that for resolutions above 1920x1200 (WUXGA) you might need a powered Active adapter and you'll need to use the Dual-Link DVI port on your card. I'm not 100% sure since all three of my monitors are 1920X1080.

 

[Mundle101]

I got my Adapter today hooked it up and works great got all three of my monitors working fine,, thanks for the help with this prob every one.

Glad to hear it!

I-INC 25" Monitor Problem

Hey guys I'm back again with another problem this time with my brand new 25" I-INC monitor, The screen shows nothing but white, i currently am using this monitor with a Active VGA Dongle,, the Dongle seems to be working plugged my 19" Samsung into and it works fine.. i even tried plugging it into my ps3 with an HDMI cable and to no avail..I can't even get the monitor menu to come up it's self, everything i try gives the same result. I was taking a shot in the dark with this brand because I never heard of them before. any help would be great..

 

[profdlp]

I've got one of those I-INC jobbers myself (See "My Specs" below) and it's running off the secondary DVI connection. I tried it on the Display Port (using the adapter, of course) and it looked good. Good enough, in fact, that I'm considering getting another adapter for it.

Three dumb questions:

1) Have you tried it using the DVI?

2) Have you gone to Display Settings and enabled it? I had a brief uh-oh moment (see Post #6 in this thread), but got it going.

3) Check the manual for how to reset it. Under Input Setting make sure Auto Search is "On".

I hope you didn't get a dud. I almost took mine back because the color temperature gave it a yellow cast on a lot of things, but after fiddling around with the monitor settings I got it good enough for a third screen.

Let us know what you find.

 

[Mundle101]

I Had it working fine on the Display port,, this particular monitor does not have an DVI input just one VGA and 2 HDMI,,as soon as the monitor is powered on the screen goes white i looked into resetting it but u have to be able to see the menu i see nothing but White, I've asked around with this problem,, seems to be if your monitor is showing nothing but a white screen something has failed.. I got it from amazon. already shipped out the faulty one hopefully get a new one soon

 

[profdlp]

Good luck with the new one.

No Display port

Hi all,

This post exactly describes my problem, except that neither of my monitors have a displayport input.... I only have DVI and VGA.

I'd be very grateful for any ideas how I can get 3 displays working without a display port input...?

I have two IBM monitors (one straight VGA connection and one VGA cable plugged into the DVI output with a DVI to VGA adaptor) and a LCD tv connecting via HDMI

Thanks
