thanks for the info. what about 1920x1200 85Hz? do you get issues when not using gtf timing (e.g. some of the timings requested by windas)?
on my old pc, i have a gtx970, which has dvi-i
my new pc has a amd 5700xt which only has digital outputs
yup 2560x1440x80 works via CRU. 425.22MHz
the first day i tried, yes i saw some weird phenomena, wavy patterns on left and right side of screen.
edit: got that again randomly. leftmost and rightmost columns of display somehow get swapped. not sure how to reproduce.
edit2: also got the...
i've owned 3 smartphones and recently a laptop (galaxy chromebook) with oled displays. they are all samsung panels. i have the following complaints:
1. black crush. and the fact that the amount of black crush varies depending on the brightness setting.
in principle this can be fixed by...
i just ordered one of these from amazon uk. i wonder how long shipping to u.s. will take
https://www.amazon.co.uk/gp/product/B01NAWRQF1/
there's also delock 62967 on amazon uk
on ebay, there's delock 62967 and 87685 available from some italian seller

if this were f520 i'd gladly spend a day driving down from illinois to get it
a circular polarizer is just a linear polarizer plus a quarter wave plate.
ideally the linear polarizer lets through 50% of light, and the quarter wave plate doesn't absorb any of that.
a 50% neutral density film should be better than a linear polarizer. but might be hard to find i guess?
OLED displays have the same issue.
circular polarizers are the best solution. yes they block 50% outgoing light but there's no getting around that if you want blacks with ambient lighting.
in terms of making black black, and blocking as little outgoing light as possible, circular polarizer >...
here's an old post where i tried on my tablet a nushield dayvue film, which is also a high transmittance ar film
https://hardforum.com/threads/24-widescreen-crt-fw900-from-ebay-arrived-comments.952788/page-290#post-1041253510
(btw i think the original ar is darker and less reflective on the...
i'm not sure you get the point.
a untreated glass air interface reflects about 4% of light intensity. (see e.g. https://en.wikipedia.org/wiki/Fresnel_equations#Normal_incidence)
a good ar film or treatment bonded onto the glass can reduce that to 1%. (if not bonded, you create more interfaces...
about this ar film stuff: i am of the opinion that a film/treatment/whatever that has high transmittance is not very useful. why?
1. in a dark room, there's no issue to begin with.
2. in a lit room, the diffuse reflections from the phosphor layer are way more annoying than the specular...
don't bother with a polarizer unless you are sure it is a circular polarizer.a
neutral density film is better than a linear polarizer.
personally i would not remove the ag film unless it's really really scratched
alignment question:
is it better to align to be parallel to the edges of the plastic bezel, or to the edges of the viewable portion of the screen (i.e. where the glass becomes solid black)
on mine, those edges aren't always parallel (only by like 1mm)
mystery solveddddd
apparently if you start off in sRGB mode in the OSD menu, you can't adjust settings except for g2 in wpb
wouldn't have spent all afternoon starting from an MPU and doing all the alignments if i knew that :P
nop it told me to do 1920x900, which is not possible in that version of CRU
but the timings are the same as for 1920x1200 with 150pixels off at the top and bottom. so i made such an image in gimp
also: in the factory preset part, i couldn't do mode 5 (gtf_107 or something). it would say the...
why exactly do old crts have worse focus?
my understanding is that with use, the cathode gets crap on it and becomes less emissive.
so somehow the voltages are adjusted to compensate, and this leads to a broader spot between g1 and g2 that cannot be focused onto the screen well?
thanks for the advice
i ordered a 60cm ruler from amazon as i figured there's no way i'd be able to hack together enough things to do geometry accurately
by the way for convergence, i think it might be better to use rgb colors like 100,0,255 because blue is harder to see than red with...
cool, thanks
i don't have a ruler with me.
does anyone know the dimensions of the viewable portion of the fw900?
my plan is to draw some pictures with carefully placed lines to eyeball the amount of unlit display at the borders
for example, if the viewable width is 500mm and I want to achieve...
well guess i need to either go with
not doing a WPB but keeping most of the stock parameters
or
MPUing and having to go through all the geometry adjustments
was the geometry guide ever posted?
did an MPU and rushed through the WPB process. this monitor's 9300K C_MAX_B_MAX is 105 (note: this is with the antiglare film). average i guess
i then loaded the original dat file that i saved before doing any adjustments and tried wpb again. again, nothing after the g2 slider works!!!
my...
ohhhh now thats interesting.
i cant figure out the equivalent on fw900.
holding the joystick-> completely white screen
left -> big white square
right -> model, serial number, manufacture date but no hours count
and... i held down reset which wiped the manufactured date (which was 2003-43)
halp...
i got windas mostly working but during wpb, the sliders after the step to adjust G2 do nothing...
edit:
k did an MPU
now the sliders work.... wtf....
hmm so image restoration decreased my black level (0.064 to 0.048) a little bit
anyway now i'll do a wpb. good thing i saved all my old files and a copy of windas in google drive :D
yes i remember the c_max_b_max thing
are there some ways to maximize tube life? for instance i suppose viewing darker content leads to less wear than brighter content. i remember Vito recommending to turn off monitors rather than using sleep mode, but i was never very convinced about how much...
i mean that i don't recall that we ever figured out what precisely it does (what parameters are adjusted).
i guess i'll fiddle with it a bit before doing a calibration in windas
spacediver do you still recommend the same software (irfanview and hcfr) as in your guide for white point balance?
i didn't try very hard, but i couldn't get it to work. i think my laptop's gpu has enough bandwidth (internal display is 3200x1800) but the adapter simply does not like to take custom resolutions...
i guess i'll move my desktop from office to home later this week. originally i was planning to...
indeed. i may have gotten really really really lucky. sharpness is great corner to corner. it's still warming up right now so i'm not sure how the black levels are. unfortunately i'm running off my laptop (intel gfx) + an adapter right now, so i'm stuck with quite awful 60hz flickering (i assume...
thursday night i went to check the two goodwill's around here. found absolutely nothing interesting. came home, checked craigslist. accidentally typed fw900 instead of "crt monitor" (at that point i would have been happy with any decent crt). there was a single post in milwaukee area. email'd...
guys...
is this site legit?
http://www.tamayatech.com
seems like they have lots of refurb'd trinitron displays for sale
(in search bar, type trinitron in description and 5000 for max price to filter out the out-of-stock displays)
yea that ebay link's price is completely ridiculous
on the other hand it seems ebay crt monitor prices just generally tend to be higher than craigslist's
this is the best i can find remotely near me

wow it's been a while since i last posted in this thread. so i've move from california to sorta the middle of nowhere in urbana illinois. unfortunately i (barely) did not have enough room to bring along my cpd-g520p, which is now sitting in my parents' garage. now i sort of regret fitting my...
yall are too caught up with the idea of using a "polarizer"
any neutrally tinted film achieves the same effect (and generally will be even better than a linear polarizer)
also idk about the fw900 film, but the original cpd-g520p film isn't "diffusing" like the matte lcd antiglare films. the...
probably. how much better it is depends though
if you find that the numbers are always quantized to some multiple of 10ms or 16ms or something, then don't trust the results too much
