Hi,
I have a Wei-Ya 2620H chassis, and have managed to get a picture on my 21" chunghwa tube. To be fair the picture is good some of the time, but never consistent. I have read that this chassis is good for 19"-20" tubes. The tube I have is 21". I contacted Wei-Ya about this and they were confident that the chassis is compatiblw with my tube. Despite this, I still have some issues that will not go away:
1) The brightness appears to vary depending on how much light and dark colours are on the screen at any one time. This has a similar effect to someone adjusting the brightness subtley as onscreen graphics change. If for example the screen was composed of 25% white, 75% black, if the screen then changes to display 50% white and 50% black, the white has less intensity than before (it becomes dim). This has a similar effect to someone turning down the brightness when the lighter colours dominate the screen.
2) As the the chassis does not allow you to adjust H-stretch, most games have about a 1" black band at either side of the screen (left and right when orientated horizontally). This doesn't bother me much at all, except that the edges quiver and distort depending on what is happening on the screen. This is quite off-putting when playing games.
3) Certain games display perfectly crisp and sharp - e.g. ghouls 'n ghosts. But others do not display sharp at all no matter what resolution I select in MAME.
I used to have a Hanterex monitor and chassis previously and never had a single problem with it until the day it died on me (a sad day). Whereas I feel I've done all I can with the Wei-Ya chassis, and still have issues. The chassis and tube are both brand new!
I'm very close to just buying another monitor and chassis out of pure frustration. If you have any idea why the above problems are happening, I would love to know.
Thanks,
Alan.
