Sony BVM-D24 & D32 comparison

[alfshusen]

Hello everybody

I recently got a Sony BVM-D32E1WU. I already have a BVM-D24E1WU from september 2004 having 19506 hours on the conter. The D32 however, got 55425 hours,
and is manufactured in May 2003. It is around 1 year older and 36000 hours more usage.

The D24 Is the sharpest monitor I have ever seen and I absolutely love it. The reason I got a D32 was that I wanted a larger screen. Both monitors has 1000 TVLines,
but since the D32 is larger, I knew it was not going to be as sharp as the D24.
I put them side by side and began to calibrate the D32's linearity and contrast to match the D24.

What I noticed first was that the color temperature was somewhat warmer than the D24, even though the setting was the same. The image also was a bit darker and the white was
not as "snow" white as the D24. It was more yellow\goldish in a way. When I adjust the brightness I simply can't get it as bright as the D24 while still maintaining the correct
black levels.

Is the reason for this color issue that the D32 has over twice as many hours than the D24?

That or not calibrated correctly.

How do I calibrate?
I have adjusted settings in monitor menu and on the bkm controlunit.

Best way to calibrate is to get the BKM-14R color probe and do an auto calibration. These can be quite hard to come by and they can be expensive. The BVM series also supports manual color calibration with a certain Minolta color probe, and a couple of other brands. This info is in the manual.

Also, FWIW, the D32 monitors apparently had a bad batch of tubes when they were first introduced, to the point that most of them had their tubes replaced early on. Supposedly the 32 inch tubes are unreliable because of their large size.

[alfshusen]

Can this calibration probe calibrate on a different level than what you are able to do manually?

I have also heard that the D32 have some issues with the tube itself. I have seen many for sale with discoloration issues and some also had several tube replacements.

When I bought the D32 I was also offered a D24 with just a couple of thousand hours on it. Almost as new. It also came with a BKM-14L probe. I should have went for that deal instead :/

Why would you go to expense and effort of finding a probe that probably went out of spec years ago at great expense when you could just get an X-rite i1 display 3 and free HCFR software, which you can also use for TV and PC monitors?

I’ve had a few problems with my D32 prior to calibration, but now it’s the greatest thing ever. Can’t complain about anything except that it’s going to be pain in the ass next time I move.

[FinalBaton]

sixbynine, have you posted pics of your D32 in action yet? If so, I would like to see them. If not then I hope you'll do soon I'm curious to see some pics of 240p stuff on it, but also 720p, 1080i@60 and 1080p@24

sixbynine: What manufacturing year has your D32 and how many hours?
Had it any issues when you got it, and how did you calibrate it?

Ah, sorry. Just checked for hours and it’s an A32, not a D32. Issues were very slight convergenze, some discoloration. Fixed via BKM-14L.

Here’s the STATUS page:

Almost 28k hours. I find the serial number interesting and wonder how many of these were even built. No Idea about the year.

Again, sorry A32. I took a couple Saturn and 720p shots, haven’t had time to test 1080i and 1080p24 (does the monitor even support this?) yet. Will post pics in fudoh’s thread. But they don’t do the machine justice, can’t seem to take good CRT pictures.

[alfshusen]

Okay, it has around the same amount of hours as mine, but since mine is a D32 the menu only shows operation hours, (I guess), and not actual crt turn on hours

It does not seem to be many problems with my picture, except I can't adjust the brightness level correct. I see at your picture that your white level is very good, as I want mine to become.

Manufacturing date is usually located on a sticker at the backside of the monitor, at least on D-series.

GeneralLight: I have seen D-24's show up here and there, also in Ohio. So just keep an eye on ebay and they show up every once in a while. I bought mine in New Jersey. But they are absolutely more common in California. I had to get my D-32 from LA.

[sixbynine]

Strange that they’d display only operation hourse (that’s crt turn on time + standby time I guess). Since who cares about the standby time. Maybe they just had not means of differentiating in the monitor.

No date on the back, last service (there’s a Sticker) in 2011. Since the serial number is so low and as far as I know they were built from '06 on I guess '06 or '07?

How do you use the BKM-14L probe? Do you plug it in and it adjusts automatically?

Maintenance menu, possible codes are discussed on this page, not sure if they work with D-Series BVMs, they certainly do with A-Series: http://shmups.system11.org/viewtopic.ph ... start=1410

If you do get in, thread lightly. Make pictures of every setting you change. Everything that can be done with a BKM-14L can be done by hand, the probe just makes it easier, faster and more accurate (reproducable). Again, this is all from my experience with the A-BVM, your experience may differ.

[alfshusen]

Thanks. Just as I thought that it could be done by hand too. I'm going to fiddle around a bit and see if i can make some changes.

[alfshusen]

Now I have done some adjustments, but just some simple stuff. My D24 runs STD color temp, but my D32 gets too warm color temp compared to d24 in STD.

COL 1 however was looking much better on D32. They are pretty close compared right now. D32 in COL 1 looks slightly darker and colors not as intense as d24. But still much better than STD.

Still it would be interesting to calibrate with a probe some time. If I can find one.

When I enter the probe option there are 5 alternatives.
Sony BKM-14L
Graseby SLS 9400
Minolta CA-100
Philips PM5639
Thoma TF6

I guess any of these probes can be used for calibration.

[alfshusen]

I found out how to tune the brightness and color level within each color temperature. Now they are more or less identical in STD mode.

[Ed Oscuro]

Was that via menu settings?

[alfshusen]

Yes, same settings this guy is talking about: http://shmups.system11.org/viewtopic.php?f=6&t=57157

[gomados]

Im looking foe KONICA MINOLTA CA-100 probe

but connector is different i dont know how this probe can work with bvm, adaptor maybe?

ok found

Does anybody with a BVM feel like trying a 1440i resolution on the monitor? You'd have to set it up with a program like Custom Resolution Utility. I'm assuming it would work because it has an identical horizontal and vertical frequency to 720p.

I'm just really curious if it looks OK, because that would make the BVM a decent PC monitor (for games and movies I mean).
