Video problem on Windows 7
Hi Everyone
I am having problems with the graphics on a new laptop from eBay which has Windows 7 on it. However, I do not have these problems with an old desktop computer that I have with Windows XP on it.
The specs of both computers are as follows:
Old Computer:
Model: Dell Vostro 420
CPU: Intel Core2 Quad CPU Q8200 2.33GHz
RAM: 2GB
OS: Windows XP
Graphics card: Nvidia GeForce GT610 (internally installed)
New Laptop
Model: Dell Latitude E6230
CPU: Intel Core i7-3540M 3.00GHz
RAM: 16GB
OS: Windows 7 Profesional 64bit
Graphics card: Nvidia GeForce GT610 (attached via a PE4C V3.0 ExpressCard PCI-E eGPU adaptor)
As you can see from the specs, the video card is the same on both computers and the new laptop is pretty high spec.
I am viewing the output from both computers on the same monitor, an Asus VG278H 27-inch monitor connected via an HDMI cable.
The problems with the new laptop is that when I play videos on it, they look a little faded and they are a little bit stuttery. However, on the old desktop computer, the colours are brilliant and the videos are very smooth.
I should point out here that before I attached the external graphics card to the new laptop, I had worse problems with playing videos. The internal GPU of the new laptop is an Intel HD Graphics 4000 GPU. I have disabled this internal GPU and the laptop screen while the external graphics card is attached.
I have done some research on the Internet about this problem and it seems that it may be something to do with the way in which Windows 7 handles GDI, hardware overlays and hardware acceleration. I don't really know much about any of this. I have attempted to do as some people on the Internet have suggested which is to adjust the hardware acceleration but I have encountered a roadblock to this: The "Change settings" button on the "Troubleshoot" tab of the "Advanced settings" for "Screen resolution" is greyed out so I can't get to the hardware acceleration settings.
Does anyone here know how I can improve the video output of the new laptop so that it is the same as the old computer?
Thank you very much.
Kind regards
Tim
