If anybody is still searching for simple answer, then in Windows 7 it's as follows: Open Device Manager Expand Display adapters Right click on a graphic card and choose Disable Wait till the screen goes back and repeat step 3 with Enable. That's it.

On AMD Eyefinity Technology, there is this remark at the bottom: Driver version 8.66 (Catalyst 9.10) or above is required to support ATI Eyefinity technology and to enable a third display you require one panel with a DisplayPort connector. Do you have one screen connected with DisplayPort?

This cannot be solved with a passive adapter. Issue is in hardware and comes down to signaling on DVI, HDMI and DisplayPort. If I recall correctly DVI and HDMI require an own clock signal per output. Because DisplayPort is a package protocol it requires only one clock signal per card. ATI Radeon HD 5000-series has two clocks for DVI/HDMI so it is possible ...

If you press Shift + Esc while in the browser it will bring up Google Chrome's internal Task Manager. If there is a process titled GPU Process, then that means Chrome is using hardware/GPU acceleration in order to display/render a particular page.

I had a similar problem on windows 8 and found that just changing the screen resolution and changing it back again resolved the corruption.

Enabling GPU scaling should solve the problem. Open Catalyst Control Center Select Desktops and Display At the bottom, click the little arrow on the upper right corner of the selected monitor and click Configure In that screen make sure "scale image to full panel size" is selected and GPU scaling is enabled If that doesn't solve your problem click ...

To fix this: Uninstall any ATI drivers on your system. Run the CCC installer but I suggest canceling after it extracts the files. Navigate to: C:\ATI\Support\10-x_vista64_wi n7_64_dd_ccc_enu\Config EDIT InstallManager.cfg Change WorkaroundInstall=false to WorkaroundInstall=true Run Setup.exe and the CCC should install without a problem

The last time I needed to do this, I had to run two separate X sessions, made by having multiple Screen sections in xorg.conf, and it involved a lot of cussing. There's been a bit of overhaul to xorg since I had to do that, but I can't imagine what you need to do is too different (other than I think that by default xorg doesn't actually spit out a conf file ...

I had had some pci_stub-related lines in my rc.local but this was apparently too late in the boot process to help, running after radeon started fiddling with things. I fixed things by moving the pci_stub kernel module stuff to the initramfs: lspci -nn | grep Cayman to find the vendor:device numbers (at the very end of the line) for the 6950 and its HDMI ...

I ran into this problem on Windows 7 with an AMD card. I don't know what that key combination is supposed to do, but it seems to switch to 256 colors and 640x480 resolution. Correcting the resolution/bit depth To fix the problem, you need to return to normal resolution (and bit depth). You can do this with either the Windows "Screen Resolution" menu or in ...

I solved the problem by going into the CCC, into Power/PowerPlay(tm) and un-checking the "Enable Vari-Bright(tm)". After clicking apply, the problem was gone.

This is a common problem with default settings of Catalyst Control Center. To fix: open Catalyst Control Center go to My Digital Flat-Panels choose Scaling Options slide the slider all the way to the right (so that it is a 0%)

I solved it! You need to unplug the HDMI cable before you do this because the driver doesn't show up in the list if you don't. If you locate the driver in "Properties", right click the speaker down by the clock on your desktop toolbar. Select "Playback Devices". There you should have the "Digital audio (HDMI)" icon. Click it and select "Properties" at ...

The upgrade advisor only tells you that Windows 7 will work. It doesn't guarantee that your hardware will perform at optimal levels. Most likely, the Vista driver issued by AMD will work fine. But due to the age of the device, AMD never took the time to validate their Vista driver with Windows 7. The similarity of both operating systems, generally, ...

Yes, PCIe 3.0 is backward-compatible with all prior PCIe implementations. http://en.wikipedia.org/wiki/PCI_Express#PCI_Express_3.0 However, because PCIe 1.0 maxes out at 2.5 gigatransfers per second (GT/s) vs. PCIe 3.0's 8 GT/s, your video card may not perform as well as you would expect when installed in a PCIe 1.0 slot.

From some AMD presentation: Each SIMD unit contains 16 stream cores, and each stream core houses five processing elements. Thus, each compute unit in the ATI Radeon HD 5870 has 80 (16 × 5) processing elements. Analogue for CUDA core is Stream core, and SIMD unit is analogue to nVidia's Streaming Multiprocessor. The difference between CUDA core and ...

Right click the Desktop then select Screen Resolution. The displays should show up there and allow you to modify the behavior.

Have you looked at the CPU and motherboard temperatures during these performance drops? It could be that either your CPU or motherboard chipset are overheating and throttling back and so reducing performance. You can check most temperature sensors using Speedfan

Your graphics card has two main parts to it, the Graphics Processing Unit (GPU) and the Memory that the GPU connects to to store data such as graphics textures. You can push each of these units to higher speeds separately, hence you have two sliders. The highest you can push these two sliders does not solely depend on how hot the components will get but on ...

Graphics card performance figures are a boggy minefield of confused and conflicting information. The memory clock figures you listed are probably equivalent in that the AMD is listed as 1 real GHz, while the Nvidia is 4GHz "effective clock" with a 1GHz real clock that is "quad pumped". Chances are the AMD is quad pumped too so the actual memory bandwidth ...

I've done a bit of googling. Apparently, it is possible to run PhysX in software on an ATI card, which should apparently be built in. However, for hardware accelerated PhysX, you will need an Nvidia card, and furthermore, as of the most recent drivers update, can't even have an ATI card in the same machine at the same time. It's possible this will continue ...

You should post exactly what PSU you are using, as this is a crucial requirement for the HD 6990. But i will go ahead and post my findings anyway. From the AMD Gaming Forums the powerdraw can be up to : 150W + 150W + 75W = 375W. But a special Overamp feature allows it to consume 187.5W from the two 8-pins connectors. So all in all the card can draw up to ...

You need to use the amdconfig tool that comes with the AMD Drivers. If you do amdconfig --help you'll get something like: AMD Overdrive (TM) options: The following options are used to get and set current and peak, core and memory clock information as well as read the current temperature of adapters. By using the "--adapter=" argument the AMD ...

The Radeon R5 230 is a rebranded Radeon HD 6450. They use the same underlying GPU and differ only by memory speed. The Radeon HD 6450 uses a TeraScale 2 (VLIW5) architecture "Caicos" GPU with 160 shader cores operating at 625 MHz. Memory is 512 MB to 1 GB of either DDR3 or GDDR5 at up to 900 MHz. Specifications: Wikipedia, AMD. The Radeon R5 230 has the ...

This is because your XFX Radeon R9 280 Double Dissipation Edition video card only has one DVI-I connection. The other DVI connection is DVI-D and can't be adapted to VGA. Output - DL-DVI-I : 1 Output - HDMI : 1 Output - mini DP : 1 Output - SL-DVI-D : 1 However, you could use the Mini DisplayPort connection for VGA using an adapter like ...

The Radeon 7750 graphics card recommends a 400W or greater power supply. If your power supply is insufficient, it will not burn out your motherboard but instead, will either fail to boot up or your system will become unstable during load.

Today I did a clean install of Windows 7 on my laptop. I never had this problem before, until today. I went to system32 and deleted atibtmon.exe. At first it won't let you delete it because it is in use by the computer, but I have this brilliant and lovely tool, called UNLOCKER, and it unlocked it and deleted it for me. Problem solved.

Had the same problem and finally solved it. It has to do with overscaling, as @ChrisInEdmonton pointed out in the comments. You have to do the following: Open the Catalyst Control Center Display the My Digital Flat Panels menu. Click on Scaling options (Digital Flat Panel) Turn Scaling to 0% This will solve your issue.

The only thing adding more ram will likely affect is the loading time between areas of the game. The more ram you have the more areas that can be kept "in memory" and will have faster access times. FPS is very tightly linked to the performance of your video card above any other factor, using a laptop you do not have many options for improving that.
