556346 2007-06-05 07:00:00 My work computer has been replaced while I was on holiday and I cannot get the page to fit the full screen. Gaps top and bottom. The colour quality is set to BEST - not sure what the resolution is. Is it the resolution I have to alter to adjust the size of the screen? The IT person is rarely at work and isn't much help at the best of times! I would rather dump the whole cruddy old thing in the bin - BUT...I do enjoy my job. Help will be appreciated. katharinem (3459)
556347 2007-06-05 07:20:00 a bit more information would be useful, what kind / size screen for example.

If the picture never fills the screen then the monitor itself needs adjusting, probably from the buttons on the front of it, however if the resolution is set to a size the monitor isn't well suited to it may be difficult to get right.

Many LCD's have an "Auto" button on the front

CRT's work over a wide range of resolutions but LCD's tend to have one default which will work best and some lower resolution "compatability" settings that won't look as nice.

Some common settings to try:
17" CRT 1024 x 768 @75Hz ( 85Hz is better for your eyes but make sure the monitor supports it before trying )
19" CRT as above or 1280 x 960(or 1024) @ 75Hz (again with the 85Hz advice)

17" or 19" LCD ( non widescreen ) 1280 x 1024 @ 60 Hz
refresh rate isn't as important on LCDs and most I've used are best set to 60Hz, they don't suffer the flicker problem of CRT's set too low, many also support 75Hz but there appears to be no advantage.

For CRT's under fluorescent lighting avoid refresh rates that are a mulitple of 50Hz as the two frequencies interact, so 72Hz can be better than 75 ( 1.5 times 50 )

absolutely agree

now my understanding of beat frequncies may be only at 7th form physics level, but if two frequencies are very close (but not identical) you will get a beat frequency which i suppose is this big fear about flourescent lights and monitors.

anyway, what you really want is a frequency as far from that 50hz as possible in order to make the beat frequency so low that it isn't noticed, whether or not it is a multiple has nothing to do with it, it just makes the maths easier:nerd:

556349 2007-06-05 22:03:00 there are usually controls on the screen itself which you'll find can stretch the pic to fit the screen however how the screen displays will also be considerably affected by the refresh rate selected.........try some combo of both drcspy (146)
556350 2007-06-06 06:17:00 the refresh rate won't affect the picture position would it? motorbyclist (188)
556351 2007-06-06 08:31:00 on a crt monitor yes it can affect the size of the picture relative to the available screen.... drcspy (146)
556352 2007-06-06 08:39:00 eh? :groan:
The refresh rate is the number of complete screens written in a second. Unless the refresh rate is increased past the maximum speed the monitor is capable of, it can't affect the size or position. At that point, the position of the picture would be the least of your worries.

556353 2007-06-06 08:41:00 that's what i thought! motorbyclist (188)
556354 2007-06-06 08:57:00 Well if I change the refresh rate of any CRT, I always have to adjust the picture as it will always change size or move, I think it's to do with what preset display modes the montor has in memory, and what settings are for each one

I have also noticed LCDs flickering like a CRT @ 60hz (these are under fluroescent light) perhaps this is also caused by interference of the building lighting and the LCD's CCFL backlight...

556355 2007-06-06 09:07:00 I suspect that the poster has now got an LCD screen, and the CRT settings are not suitable for it. If it's got 1024 lines and the video card gives it 768 lines, there will be a lot of blank lines on the screen. Graham L (2)
