I just bought an emachine (t2792) from BestBuy. I only seem to have blue, yellow, white, and black for colors. I’ve tried going to the setting and changing display. My wife (who knows more then me) has spent a couple of hours trying to get it to work. Still only those colors.
Is it an inherent feature of this machine to have only these colors? Or is something realy wrong with it. If it an inherent feature, I WANT MY REDS…AND PINK…AND GREENS…and all of the other 256, 4,000 or bijillion colors.
Do I need to get a different “color card” or whatever to get these colors?
Sombody will tell you more than I know. I will assume that an emachine is just a PC and that it has Windows XP
hit start button in the lower left, hit control panel,click display icon,click the settings tab, screen resolutin 800x600, color quality- highest,32 bit
You can right click on the desktop (anywhere on the background that is not an icon or some other object) and choose properties.
Then go to settings. Make sure the resolution is what you want (higher equals more desktop space, but if you don’t have a large monitor everythign will look smaller) and make sure the color depth is set to 32 bit (highest).
All color CRTs utilize a shadow mask or aperture grill a fraction of an inch (1/2" typical) behind the phosphor screen to direct the electron beams for the red, green, and blue video signals to the proper phosphor dots. Since the electron beams for the R, G, and B phosphors originate from slightly different positions (individual electron guns for each) and thus arrive at slightly different angles, only the proper phosphors are excited when the purity is properly adjusted and the necessary magnetic field free region is maintained inside the CRT. Note that purity determines that the correct video signal excites the proper color while convergence determines the geometric alignment of the 3 colors. Both are affected by magnetic fields. Bad purity results in mottled or incorrect colors. Bad convergence results in color fringing at edges of characters or graphics.
I don’t know if a faulty video card could cause these problems. Your best bet is to return the monitor (or the entire system) and let the store replace it.
I suggest checking the monitor cable to make sure that it’s seated correctly both on the back of the computer and the monitor itself. It’s possible that one of the pins is not making contact correctly. Also, check that none of the pins are bent.
I once had a similar problem, and eventually found the cause: two of the pins on the monitor lead were bent up and not making contact. I straightened them with a pair of pliers and it was fixed. Just an idea.
I replaced the monitor with an old one and have good color. So you guys seem to be right in that it is a monitor issue. I’ll check for bent pins on the new one, otherwise it’l need to be replaced.
