I recently upgraded my monitor from a standard 17" CRT to a brand new Samsung 24" widescreen LCD. This required me to switch my resolution from 1024x768 to 1920x1200. But everything now is so DAMN SLUGGISH! I'm not talking games--see, even general purpose things like scrolling up/down webpages, or watching movies on DVD or Youtube are very slow now!! If I switch to 1024x768, everything is fast again. But, this monitor was made to run at 1920x1200 and looks a little blurry running any other resolution. I have a newish 7600GT for AGP, and the latest drivers from nvidia.com are installed, yet I feel that video acceleration is being switched off at the higher resolution. How do I fix this?

To me it seems like you graphics card, it wasnt made to run at such high resolutions. Read this with only a 128-bit interface and a 256MB frame buffer. This means that it has limited memory bandwidth, but this only comes into play at the highest resolutions, while few games require a 512MB frame buffer yet. Anyone with a 17in TFT panel won’t have a problem. i googled "high res slow computer"

fiddle with the resolution till you find one which coincides with the dpi of the screen it looks blurry because the resolution isnt quit matched with the screen. the idea is so that you can get a whole ratio so 1 dot from the graphics card is displayed on say 4 dots on the lcd. if its not a good ratio like 1 to 1.5 then you will lose data and it will look blury all text needs typos. There there for the reader to find,to distract them from the total lack of content. google it! wasnt the answer to the question i asked so dont be dense and give me that repl

This is your problem: "Dell Dimension 4400 Pentium 4 1.9GHz 1024MB RAM DDR PC2100 nvidia 7600GT AGP Windows Vista Home Premium" You are underpowered and under-resourced for Vista. I guarantee that Vista is gobbling up at least 66% of your resources before any drivers/programs are loaded. Your Memory is running at pc2100 which is 266FSB - way, way, way, too slow, you should be running minimally at pc3200/400FSB for Vista, and you have a bottleneck because your CPU is running faster (I think, I didn't take the time to look it up). In addition, you are running a CPU rated lower than 2GHz, and an Intel at that which has data pipelining structure making it slower than an AMD processor running same clock. Considering the above stats, I would guess that your power supply is borderline underpowered, probably around 300-350watt. Put it all together, and you will never get full performance you are looking for, especially if you try to add new technology as in your video card.

"yet I feel that video acceleration is being switched off at the higher resolution. " Go into your bios Setup and make sure the video is set to initialize AGP video first, and if there is a setting to set the AGP X speed, set it to the fastest speed both the card and the mboard supports. If you no longer have the original Dell software installation installed and you loaded Windows Vista from a regular CD or DVD, after Setup is finished you must load the drivers for the mboard, particularly the main chipset drivers, in order for Windows to have the proper drivers for and information about your mboard hardware, including it's AGP support. Dell often does not have the main chipset drivers listed in the downloads for your model - in that case you must go to the maker of the main chipset's web site, get the drivers, and load them. Some Windows Plug and Play Monitor driver settings often don't work well with LCD monitors, especially larger and/or widescreen ones. Load the drivers for the monitor from the CD that came with it if you haven't already done so. Windows will then by default show you only the settings both your monitor and the video drivers support. "If I switch to 1024x768, everything is fast again. But, this monitor was made to run at 1920x1200 and looks a little blurry running any other resolution." Higher resolutions and numbers of colors require more from your system. The video card will handle the higher settings fine, but if your system is a little short on resources (your 1gb of ram may be marginal in that situation in Vista), your video will perform noticably slower at higher settings. In that case, leaving it set to 1920 x 1200 and simply switching to 16 bit rather than 32 bit color will improve video performance, and most things won't change in appearance. 1900 X 1200 is the "optimal" or "native" resolution at which this LCD monitor display looks the best, but when you have a quality monitor such as a Samsung, it can still look nearly as good in lower resolutions, but the text may be harder to make out. Turn on Clear Type in Windows XP or Vista - makes type/fonts on LCD screens look clearer. http://www.microsoft.com/typography... .... I have been told by a pro who builds custom systems all the time you don't ever need more than 350 watts PS capacity if your mboard has no PCI-E slots, unless the computer is a heavily loaded server. If your present PS capacity is 300 or 350 watts it's fine. In any case a PS of not enough capacity is extremely unlikely to slow down your system.

Tubesand wires: why do most medium and hi-end video cards have separate power cords? Why do all mainboards have 4-pin molexes?? If you can answer that you will see the falacy of your theory.

Well, my computer only supports 1GB of RAM, and according to Dell, it will only take PC1600/2100. Actually, Vista's taking far less than 66% of my resources--only 39%, even at 1920x1200. My power supply is a PC Power and Cooling 360w, which I bought at the same time as the video card upgrade. I am using Vista's built in driver for my Intel 845 chipset, because Intel doesn't have Vista drivers on their site. Let's see here...AGP is set to initialize first, but there is no way to set AGP X speed. Perhaps it's fixed at optimal speed? When I set it to 16-bit color, everything really looks different. For example, I've set my windows to have a dark-red, translucent look, but now it's light-purple and isn't translucent. Even the minimize/close buttons look different. It DID speed up Internet scrolling A LOT, so that's a good thing. But DVD and youtube playback is still not very smooth. Thank you, guys, for your help and suggestions. Anything else I should try?
