When you switch back to the desktop, the desktop darkens and then goes back to the game, and the game is dimmed. Turn the brightness to maximum use. It's not very dark, just like looking at the LCD monitor.The monitor was just a year old, and school time was almost never used!The monitor is Samsung SyncMaster740NW, and the warranty period has just passed a few days.How much would it cost if it were not guaranteed?Two days before the display back to normal, but these days are just fine, I do not know what is going on?
I don't know what brand of display you are.Liquid crystal display mainly rely on the tube to light, brightness dimming, can be said to darken the tube.General display more than one tube, there are 4 lamps, you such a problem should be estimated one or 2 lamp does not light, it is the simple tube may be bad few, maintenance costs should be 50-100 yuan
The trouble of LCD should be that the power supply of the power supply circuit of the lamp tube is reduced, and the brightness is decreased sharply;There are two reasons for the power reduction of the lamp supply circuit:1 、 the load capacity of the monitor main power supply is reduced; the filter capacitor and diode in the rectifier filter circuit are not good, or the gain of the power switch tube is low (usually the bias resistance is changed);2 、 the fault of the lamp supply circuit;Landlord can borrow other people with the same type of power to try, see if the problem can be solved;If not only repair.
Graphics cards are not very good for game support. That's OK. It's normal.It will recover slowly.
Right click on desktop - Graphical attributes - color correction - brightness, drag blocks to enlarge brightness - apply - make sureHave a try.
Yes, there is something wrong with the backlight source. Samsung repair more expensive, it should be in more than 100, and the specific you still play his repair phone, say the situation to him, and then ask.
