The LCD monitor seems to be a mixed blessing. The image feels a bit crispier and the widescreen format is very nice in applications with a lot of palettes and extra windows, but the viewing angle is atrocious. It's enough that I lean back in my chair for the image on screen to appear 50% darker, and if I move my head sideways ever so slightly the image gets a yellow-ish tint. Don't know if I've just picked a bad model (which would be fully in line with my usual luck), or if LCDs in general still have a way to go before reaching CRT-level viewing quality.
I'm afraid that this is due to the inherent flaws in the type of panel that you chose. Your Samsung T220 has a 6-bit TN panel. While this type is the cheapest and has the fastest response time, it also has a reduced color gamut and the horrible viewing angles that you mentioned. I should have mentioned this before you bought it, but I made the mistake of assuming that you already knew about this stuff. My bad. :(
The other main panel types are VA (which includes PVA and MVA) and IPS. Both types are 8-bit and capable of displaying true color without dithering. They also have a much wider viewing angle. They are, of course, more expensive (IPS is a lot more expensive) and have drawbacks of their own, but they are generally much better than TN as far as image quality is concerned. One of their main drawbacks is that they are generally only available in panel sizes of 24" or larger. Here (
http://en.wikipedia.org/wiki/Thin_film_transistor_liquid_crystal_display) is an general explanation of the different panel types.
One thing that you can do is get the most out of your monitor by properly calibrating it. Forget about the factory presets. Chances are that they are way, way too bright, and that the colors are oversaturated to compensate for all of that brightness. While this is good for in-store display purposes it is not good for general use because staring at a monitor that is too bright for hours on end can be very harmful to your eyes. It should only be just bright enough to be easily viewable in a well-lit room and no more.
Start out by setting your video driver's color control to the default settings, and darken the room that you're in. Then visit this site (
http://www.lagom.nl/lcd-test/) and run through the tests. AFAIK, this site is the ultimate LCD monitor calibration tool. You're probably going to have to lower both brightness and contrast a lot. Use the adjustments on your monitor first to get the settings to as close to perfect as possible before you even touch your driver control panel's adjustments. That way you'll end up with the best contrast.
Be warned: this is going to take a lot of time, fiddling, cussing and eyestrain to get it right, and you will never get it perfect because of that TN panel's limitations. While testing, try to sit in the same position that you will be in while viewing the monitor for the majority of the time that you'll be using it because that terrible viewing angle is going to drastically effect these tests. What I do is scroll the pages so that 2.2 in the gamma test, the darkest set of squares in the black level test and the lightest set of squares in the white saturation test are in the middle of the screen while I'm making adjustments. In a nutshell, you're just going to have to find the best compromise that you can while still passing both the black level and white saturation tests. By passing, I mean being able to see the darkest square in the black level test and the lightest square pattern in the white saturation test without having to stare at them. If my cheap-a$$ed Acer AL2216W can do it, I'm pretty sure that your Samsung T220 can. ;)
In order to achieve the best contrast, you're probably going to end up with dingy, grayish whites. It's just a limitation of the technology. You'll get used to it, and you won't even notice it after a couple of days.
Games seem to be a mixed bag as well. Some games that didn't work so well on my old computer seems to be running a lot better on the new one, like Mass Effect and Neverwinter Nights 2, though I still need to use medium graphics settings in NWN2 to get playable frame rates. At least other games can be run with all settings turned up with good performance, and I managed to play Mass Effect for 4 hours straight with no lockups, hickups or crashes.
Other games that I never had any problems with on my old computer seems a lot less reliable on this new one, like Bioshock and Guild Wars. The former crashes after like 5 minutes or play, while the latter sometimes freezes during area transitions forcing me to reboot the computer. I also get some weird noise flickering over the screen image when playing some games. Tried playing Tomb Raider:Underworld, but that seemed to make the graphics card flip out, giving me a screenfull of green lines followed by a crash after just playing for a few minutes. I managed to just barely get through the first tutorial area, but crashed on the boat before I even had time to jump into the water.
In summary it seems to be the same old story repeating over and over. While some things get better when upgrading to a new computer there are always tons of problems and things can never ever just work as intended. A bit tiring, but I guess it's a natural law or something. :)
There have been a lot of reports going around the interwebs about the problems that the newer drivers from both ATI and Nvidia are having with older games, but you should not be experiencing any problems with the newer ones like Bioshock.
I do have a very possible solution, but I doubt that you'll want to hear it. I've tried to be polite about this before and you ignored me, so I guess that I'm going to have to be blunt this time around:
Do you seriously expect everything to be hunky-dorey and for everything to run flawlessly on an XP install that's, what, how many years old now, and has been transferred to how many very different systems, each with very different hardware, now? C'mon, stoffe! Surely you know better than that!
So please, FOR THE LOVE OF GOD, JUST REFORMAT AND GIVE THAT POOR MACHINE A FRESH INSTALL OF XP! :xp:
At the very, very least it would eliminate a corrupted OS install as a possible cause of the issues that you're experiencing.
