XPS 430, U2412M, Asus AMD Radeon R7 260x

Jump to solution

Hi All

I currently have a Dell XPS 430 (Intel Core 2 Quad Q8200 @ 2.33ghz), 8GB Ram running on Windows 10 Pro 64bit and 375W PSU.

The original graphics card (Radeon HD 4850 (512M) recently died. I had two monitors connected to it (Dell U2412M and Dell P2210).

I replaced it an AMD Radeon R7 260x.  When I first installed the new graphics card and started the PC both monitors loaded. Once the Drivers installed and the PC restarted the Dell P2210 loads fine from startup and within Win10. Unfortunately I have tried the various connections on the 260x but the U2412M goes into 'Entering Power Saving Mode' from the startup and is not detected within windows.

I have tried reinstalling the drivers....uninstalling....re-installing from Asus website....reinstalled monitor drivers.....not sure what i'm missing here.....please help!!!

What are all the kinds of ports on the AMD Radeon R7 260x? DVI-I, DVI-D, display port and hdmi

Which one appears to be #1 ... which one is working now? Dell P2210 is the only one that appears in display settings.

Dell P2210 - Native Resolution: 1680x1050 (vga, dvi)

Dell U2412M - Dell U2412M: 1920 x 1200 (vga, dvi, display port)


I would run the P2210 on DVI (or maybe just where-ever its working now)

I would run the U2412 on DisplayPort (with native DP cable)

Hopefully, both of those ports on the AMD-260x can be used concurrently. 

I don't use converter cables unless absolutely necessary. I try not to use HDMI unless I'm doing HTPC in Home-Theater. However, exceptions are allowed to get something to work.

When you say that the monitor is not detected within Windows I assume you right-clicked the desktop and select Display settings and tried to Detect the monitor. Is this correct?

Have you tried the U2412M by itself the the cable used for the P2210?

Only one of the ports on the AMD Radeon R7 260x will be Monitor-1.

To get the others to work, you have to Extend the Windows Desktop to it.

1. What are all the kinds of ports on the AMD Radeon R7 260x?

2. Which one appears to be #1 ... which one is working now?

3. If you need further assistance, it would help to know for each Monitor ... Native Resolution and all available Inputs Port types.

Also, IIRC ...  AMD Radeon R7 260x is kinda old. If so, it might barely work in Windows-10 64-bit. However, if it looks OK on DeviceManager ... you might have dodged that bullet.

thanks for the reply. Yes not recognised from startup, from display settings or from when I click detect monitor.

Tried the u2412m by itself using P2210 cable, a hdmi cable via dvi adaptor, display port adaptor to dvi...still nothing

You said the Dell U2412M did not work by itself with the P2210 cable. I assume all you did was swap the monitor at the end of the cable. Did you make sure that the Input Source selection on the U2412M was set to either Auto Select or whatever you are using for the P2210 (VGA or DVI)?

According to the U2412M manual, 1680x1050 is also one of the preset display modes, so it appears that both monitors support this display mode.
