I wonder how easy this would be to repair
15:11
<
Sarayan >
you need to change the connector
15:11
<
Sarayan >
that's what, 15 pins?
15:11
<
andlabs >
seems to be a permanently attached cable
15:11
<
Sarayan >
that's surprising, but heh
15:11
<
andlabs >
this monitor has not sold for two months or so
15:12
<
andlabs >
the only reason why I'm paying attention is because it's FEDERAL EXPRESS branded for some reason
15:12
<
Sarayan >
the question is whether it's damaged in the first place though
15:13
<
andlabs >
well some of those missing pins are signal pins so the monitor won't actually display an image properly
15:15
<
andlabs >
actually huh both hsync and vsync are present on that cable, so the image shouldn't look that messy
15:15
<
andlabs >
oh wait the sync grounds are missing
15:17
<
andlabs >
also with only red connected that image should be red
15:17
<
andlabs >
unless this is somehow vga monochrome
15:17
<
andlabs >
or maybe this is one of those early vga monitors that literally only supports the resolutions of the original vga card
15:18
<
Sarayan >
it may be damage, but in a way it looks too clean
15:19
<
Sarayan >
as if the pin was never there rather than it broke
15:21
<
Sarayan >
anyway, I need to dump all the data we need to add
15:22
<
Sarayan >
gah not here
15:23
<
andlabs >
"needing to dump all the data" is a mood
15:24
<
andlabs >
also huh no one seems to want to say what the original VGA card was
15:24
<
andlabs >
or even the original VGA chipset, which I do get was an IC
15:24
<
andlabs >
I wonder if it's been decapped

andlabs: are ypi sire that
19:53
<
Foone >
andlabs: are you sure that's damaged, and that's not just one of those weird monochrome VGA monitors which only have some pins?
20:13
<
Sarayan >
Foone: pretty much what I was wondering too, because it doesn't look damaged
20:46
<
andlabs >
I don't know
20:47
<
andlabs >
it may require opening up the thing to find out
20:53
<

foone sur Twitter : "And here's the VGA cable for it. Notice that it's actually just MISSING the blue and red pins.… "

so the question is then what's going up with that bad image
22:29
<
Foone >
if it's anything like mine, it's VERY picky about what sync rates it supports
22:29
<
Foone >
so they may just be running it at something it can't do
23:39
<
andlabs >
if you want to find out it's $30
23:40
<
andlabs >
I probably won't get it
