91331 2002-10-21 03:58:00 My 2 year old 17" PC Co. monitor aka. Likom 7034 has recently run out of adjustment on vertical size, contrast and brightness. Horizontal size has adjustment to spare. Generally everything is OK but I'm losing about 6mm on the top and bottom of the screen. I tried an identical monitor from another computer and after fiddling with the adjustments I was able to set everything with out getting anywhere near the maximum. That should rule out the video card. I have set my display at 1024 x 768 & refresh rate 75hz. Different settings alter things slightly but not enough to fix the problem. I'm on Windows ME. P3 & Geforce 2 MX Anyone got any ideas. Thanks in advance i-gordon (962)
91332 2002-10-21 04:04:00 Hi i-gordon

I have the identical monitor/graphics card/operating system/P3.

My settings are:

refresh rate: optimal
H-size: 38
V-size: 60

There will always be a black edge around the side, it is part of the non-viewable area of the screen.

Hope this helps.

91333 2002-10-21 04:04:00 Can you give it a go on 1024*768*85Hz? MadCap (2304)
91334 2002-10-21 04:16:00 Hi again, I might as well give you the rest of my settings to try on your monitor:

Contrast
95

Brightness
81

Information (i)
VESA- 1024x768
H: 68.1 Khz +
V: 84.2 Hz +

GRB colour manager

B 45


Let us know what these settings do for your monitor.

91335 2002-10-22 04:53:00 Thanks for the replys. None of the settings make anything more than a small change. I should have mentioned that the settings I have now are as good as it gets. I was hoping a tech person or 2 might be able to tell me what is going on with the monitor to cause this situation. i-gordon (962)
91336 2002-10-22 05:10:00 Well, the EHT may be a bit high. That would mean that the deflection factor is less, so you are not filling the screen. Technical enough? :D Graham L (2)
91337 2002-10-22 09:39:00 Thanks Graham, I think U got me. What is EHT and how do I fix it.

91338 2002-10-22 09:47:00 EHT is Extra High Tension (about 25,000 volts)

Unless you are well informed, trained and qualified you dont fix it. Or it will fix you.

If the voltage is too high, the beam travels so fast it doesnt get time to be deflected as much. The same circuitry is involved in the horizontal scanning section, which *could* also explain why you have plenty of width.

This is a dangerous place to play, so I wouldnt advise it. The EHT will easily jump an inch or two, so stay away!

Its a job for the service people, they have the necessary probes to measure the voltage. As an aside, does the size of the image change between a white screen and a dark one? If it does that can be a pointer to poor EHT regulation.

Unless you know this field, the technical explanations won't help, and if you are knowledgeable then you didn't need them anyway....catch 22

91339 2002-10-22 09:54:00 Thanks Graham, Really getting thick now.The image size is constant, white screen, dark, screen saver, background, everything. Not even a hint of change.

91340 2002-10-23 21:00:00 It looks like the end of the line on this one.Thank for the info godfather my mistake. ! last query. Anyone recommend a service shop in South Auckland to fix this problem. Thanks again everyone for your input. i-gordon (962)
