CRT ghosting??
Hi,

I've been using LCD monitors for a while and just changed into a crt, Mitsubishi diamontron 2070 SB. Color reproduction and image quality are great, much better than my Samsung 151s LCD.
It just that people are talking about ghosting with lcd in comparison to crt, how can I detect this? It just that in doom3, with my new crt, I saw the lights are trailing, is this ghosting or is it just the way the game is? I haven't compare this to my old lcd though.

It's probably easier to spot ghosting in 2D. Try moving around a small window over a bright desktop background for instance, to see if the edge leaves ghosting marks. CRT's hardly ever show a ghosting effect unless something is wrong. Games might have some effects intentionally.

easy way make your desktop black. make sure your mouse is white. move your mouse and you will see ghosting on your crt....

anyway i get heavy ghosting if I do this even on my crt.. however when I play cs and stuff i never see any ghosting but if I use my LCD I get really bad ghsoting when gaming

ghosting a CRT depends on refresh rate and overall quality of the video card and crt.... even the cable between the 2...

You should attempt to find a Monitor Calibration tool of sort and run some tests... find a resolution and refresh that works... adjust plenty of things.... sometimes having the brightness to high or to low can results in "ghosting" with a pitch black surface vs a white mouse pointer.. (usually the only thing that'll show some form of ghosting)

I get ghosting on my TVM AS6S crt... it was cheap though... my next major purchase will be a nice NEC monitor.

I saw ghosting here with a pitch black surface and a white mouse pointer. So is there anything wrong with my monitor?
Or do i need to reformat my HDD since i haven't reformat it after i replace my LCD?

Nope, not much you can do... make sure that the refresh rate is as high as your monitor supports for whatever resolutions you're using.

Phew.....I thought my monitor might have ghosting problem in games
but......
I still have the ghosting problem when I have black background and white mouse pointer. Could it be because i don't run the monitor at the recommended resolution, which is 1600*1200@85Hz (btw i'm running mine at 1280*960@85Hz)? Will increasing the refresh rates solve the problem?
EDIT: The max supported refresh rate is 120Hz.

I'm currently at work and test the problem on diamond view 17" at 1024*768@85Hz and guess what......no trailing even in the black pitch background with white mouse pointer . Hmm....maybe because of the background light here?? It's very bright here. I thought the diamondtron supposed to be the better one......well it has better color and image quality but ghosting???

So it isn't a problem with my monitor then.
