One, the adjustment of high resolution

14 inches of VAST SVGA of a compatible machine, when resolution setting is 800X600, screen is spent below DOS and Windows, can use below the resolution of 640X480 only. But when the software such as CAD and Quake3 runs below 640X480 resolution, indication form of a written or printed character and graph are very coarse, exercisable is actual screen space is narrow small, as real as the delicate and exquisite indication screen that resolution is 800X600 great difference, day, is what this machine matchs TNT 2 Ultra unexpectedly (does somebody topple? ) 　
Observe the grating of this monitor, window is very fine, can judge by old experience, this should be a monitor that 0.28mm dot is apart from. The geometrical distortion factor of besides grating is very minor also, knowable the quality of this monitor is good still, be not the vintage VGA monitor of low line frequency. The cause that cannot install high resolution is probable the line frequency that is monitor is by in-house setting on the resolution of 640X480 (the colour on a lot of vintage servers is shown often is such) , and cannot be the same as foot to rectify line frequency by oneself when 800X600 resolution, created afore-mentioned appearances consequently. 　　
Undertake adjustment by the following measure: 　　
1. is in the main circuit of monitor board on the fine tuning potentiometer that finds the 31.KH2 that adjusts line frequency synchronism and 35.5KH2, and be adjusted relevantly H.PHASE of potentiometer of phasic fine tuning all right place. (if lack corresponding professional knowledge, as long as to " 31.2KH2 " wait for a few key word to be searched one by one, be no problem. )

2. open lead plane, adjust the extent of grating, standard reference conditions is till direction. (the purpose of this action is for next suddenly synchronous line frequency is adjusted provide a proper grating place. )

The order that 3. enters resolution to be 800X600 below pure DOS condition (be like See1.3 of classical program seeing a picture) , right now monitor begins to lose a condition, screen shows the horizontal horizontal line of many scroll, the choice undertakes adjustment operating below pure DOS system, because the stability of the switch of resolution is right now taller,be.

The potentiometer of synchronism of 4. adjustment 35.5KH2, picture synchronism, and hold the position correct, resemble broadcasting slide same, very easy. Of course, patience or must. Attention, 31.2KH2 synchronism potentiometer is adjusted when some monitor, see at Euramerican old brand colour is shown more.
