HD 5450 issue

Hi,

Recently bought a HD 5450 to go alongside my r9 270x, I've installed the card and I can see it in GPU-Z, but can't find it in CC and when I connect a monitor to it, the monitor doesn't receive a signal. Any ideas on what the issue could be?

Have already reinstalled drivers and reseated the card.
 
Which drivers are you using? The R9 270X is will run with the normal drivers, but the HD5450 has fallen into the Legacy support so needs different/older drivers to function. Wonder if your 270X drivers are missing the parts to recognise/run the 5450.
 
Ok, managed to get them working on the beta driver, problem now is I have 2monitors plugged into the r9 270x and one into the 5450, the two monitors plugged in to the r9, the computer only recognises them as one and just duplicates the screen. Is there any way to get the computer to recognise the r9 has two monitors in it without updating the drivers? My overall plan is to have 4 monitors, 3 via the r9 and one in the HD5450.
 
Sounds like the screens attached to the 270X are in Eyefinity mode. Have a look under Eyefinity in Crimson settings and see if you have the option to disable it. If that leaves one working and one blank, check Windows display settings and Extend the desktop onto the blank screen.

Taking a step back, might it be easier to get all 4 working off your 270X? Or some from the GPU and some from your CPU onboard graphics - if it has it? What's your setup - motherboard, CPU, and monitor make and models?

I've previously run 4 monitors from my R9 290's (and once from a single R9 285), but now run 3 from the GPU and one from the Intel onboard as I've found a couple of games are happier with it this way round.

I've read you can't get 4 monitors off a r9 270X as the hdmi and dvi are linked?

Eyefinity is disabled.

Don't have an onboard GPOU, running an alienware x58 motherboard, i7 970 and the GPU is a sapphire toxic r9 270x.

Not heard of the HDMI and DVI being linked on the R9 270X, and it's not a standard feature of the card (https://www.techpowerup.com/reviews/MSI/R9_270X_Gaming/3.html mentions all 4 outputs being usable at the same time). Which make/model of R9 270X do you have as I'd hate to lead you down the wrong path if yours is different?

What make and model are your monitors, and do you ever hot swap them (unplug/replug when the PC is power on) or are then always connected at startup and remain that way?

The reason I'm asking is that the R9 series has only two clock generators (as have all AMD cards since the old HD series at least), and any DVI/HDMI/VGA output needs a clock generator, so you're usually limited to two DVI/HDMI/VGA outputs on the card. However, the R9 series has a special feature where if two monitors are the same make and model, and are plugged in at startup, they can share one clock generator - hence my three E2409HDS monitors are connected by DVI, HDMI and DVI and all three work fine. DisplayPort outputs do not need a clock generator so can be used if both clock generators are already in use. Passive DP adapters to DVI/HDMI/VGA still use the GPU's clock generator, but Active adapters include their own so don't use one of the GPU's.

So depending on what monitors you have, and what connections they have, we might be able to get all four working from your R9 270X without needing the extra GPU. :)

I'm running 3 different monitors, a Samsung T220HD, an Iiyama E435S, both have different resolutions and I'm running a Dell U2515H via the DP. My 4th monitor is going to be a 50inch tv

Wow - that is a pretty diverse set of screens mate! :)

OK, so we're definitely going to be limited to two DVI/HDMI/VGA outputs active at once from your 270X. Glad you've got a native DP screen there, as that saves messing about with Active adapters.

Just re-reading your earlier post and you mention you've got the screens working but one is duplicated. If you go into Windows display settings (usually right click on Desktop will give you the Display Settings option), can you highlight each monitor and select "Extended Desktop" on each?

So when I had the 5450 drivers installed, I kept two monitors plugged into the 270x, however, when I go to display settings, it only shows one monitor, both monitors work, but the computer thinks there is only one and just duplicates it. No option to extend. I've also got an active adapter if needed. I'm thinking it might be easier to buy a MST hub or an r7 240? Would probably solve this driver issue.
 
Either option would probably work, as would using older drivers from before the 5xxx series stopped to Legacy support.

Assuming you're running Vista or newer, it might be easier/cheaper to add the cheapest Nvidia card instead of the 5450. Nvidia drivers and AMD ones can happily coexist (albeit with some quirks, like Nvidia disabling PhysX when it recognises an AMD card is present) and that way you could have the correct drivers installed for each card.

Alternatively, might be worth looking on Guru3d forum and see if anyone has modified the latest AMD drivers to support the 5450 too, which should also sort your issues.

Do you know what drivers I could use? Tried the last beta one for the 5450 and an older one, but neither worked.
