Running 2 Graphics Card for 1 Monitor

by sniping_dreamer / January 13, 2007 9:24 AM PST

Hello,I recently bought a Radeon 9250 256MB PCI graphics card for my computer. Unfortunately, it only runs Direct X 8.1. This does not fit into many games of today's world,and also causes some programs to run slow (for example, Google Video runs slow for some strange reason, Flash have poor refresh rate, some games just goes down in refresh rate).

This is my question: Is there a possible way to run my integrated graphics card (an ATI Radeon Xpress 200, with 128MB,and is Direct X9), and the PCI graphics card at the same time, so they can dually run under one monitor, and adding up to a total of 384MB of video, like how normal RAM is run?

If not possible, any way to fix my refresh rate of my monitor? I'm pretty sure Google Video doesn't rely on Direct X9,so I think it's my refresh rate. I mean,for my computer, it's a bitter sweet. In one corner,some old games run faster (BZFlag, Wolfenstein, WarRock), while in newer games (like Project Snowblind)go lag like molasses. I did not have any problems with this before I had this video card.

For completion. The answer is "no."

Such is not a feature of your selected video cards.

No can do.

No video monitor can display 2 video sources at the same time, unless in the rarest case, it has Picture-in-picture (PIP) like many modern big screen flat display TVs have. Unlikely in small dimension PC displays.

What you may be thinking of is the relatively new dual bridged video card technologies from Nvidia (SLI) and the ATI equivalent (I forget the name) where they have 2 identical or compatible PCIe slot cards bridged together and running in sync sharing the number crunching and GRAM. However even in those scenarios, there is still only 1 resulting video output signal generated that goes to the monitor. The monitor doesn't know or care what's creating the incoming signal, as long as it is compatible and readable.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
