I got plenty of broken LED screens, but no time. You would leave the inverter as it is (for the LED indicators), but drive the LEDs with a small electronics board in PWM mode.

I presume that mod would reduce power consumption and improve battery life also?

I'd love to perform this mod!

Do you by any chance remember where you saw it? I am willing to give it a try.

Hello all,

I just would like to add, that I, too, replaced a SXGA (T60(p) 15"inch) with a UXGA from the above mentioned source in China (Taiwan?) : ebay-Seller ID: cgsplcd

Delivery was very swift, it was completely new, well protected and properly cushioned. The display is bright and of best quality, no dead or stuck pixels.

The new display is just perfect.

The BOE hydis HV150UX1-101 although is the same panel, i don't think it has the EDID EEPROM of the HV150UX1-100 so probably will not show a display etc.

Hello All ..
I can guaranteed the HV150UX1-101 ,100% workable on IBM's T60 same as HV150UX1-100 ,the EDID value also ,so don't worry ,if you can not workable ,i accept 100% return ,thanks !!

beeblebrox wrote: Then I had a few T60 SXGA+ with the infamous IPS from LG-Philips. They had a very poor supplier with CCFL lamps which lasted only about 6 months and then started fading drastically. After about 2 years all LG-Philips SXGA screens were yellow and dim. I replaced the CCFL lamps myself (as usual) and used lamps from a broken Samsung LCD which are known to be bright and have a blueish tint.
Result: excellent SXGA displays. So the problem was the subpar CCFL supplier for LG-Philips.

As an owner of two LG-Philips SXGA+ IPS displays (one slightly yellow and reasonably bright, one very dim), I would also like to try the CCFL replacement on my very dim panel, which is otherwise perfect (no dust spots, pressure marks or dead pixels) -- if anything goes wrong, I still have the brighter panel available for use.

I switched back to the SXGA+ display after having used the Hydis UXGA -- and being spoilt by its excellent brightness and white point -- but unfortunately the text is too small to read for comfortable use

Can anyone recommend a good source (in Europe) for CCFLs? I have found the following offer from a Chinese seller in the UK, which is very cheap:

http://cgi.ebay.co.uk/15-1-laptop-LCD-T ... 3f0817c388

What are your thoughts? Is the length correct (310mm)? Is it better to go for a more expensive CCFL from a different supplier? Or is it just pot luck? Will this one go yellow in no time just like the original LG-inbuilt one did?

Also (question directed primarily at beeblebrox and perhaps others with experience), what did you do to prevent dust getting in? I have heard stories of people doing the CCFL replacement in the bathroom just after having run a hot shower to create a dust-free environment -- is this necessary and does that work?

Thanks in advance,

Why not bump up the DPI if you prefer the Hydis LCD? It works quite well in Vista, Windows 7 and Linux. It doesn't work quite as well in XP where some fonts are hard coded and won't get bigger.

Good question. I tried it and wasn't really happy with the result (I'm using Ubuntu btw. but would expect similar results with Windows). The biggest problem is with web sites, as the graphic elements generally do not scale (or scale in a jagged way) -- if you scale the text above a certain percentage, it will no longer fit inside the available space. And I like to be able to sit back when reading Web sites like this one

The other issue is that I am using an external monitor with a docking station when at home -- the lower DPI is ideal there, which helps to maximize the amount of workspace. So I find the SXGA+ resolution to be the most practical solution for me, even if the panel is not as good.

Hello all ..

OK - Out of curiosity ordered a BOE hydis HV150UX1-101 panel from cgsplcd and can confirm it works a-ok in a T60 - Although the spec sheet for the HV150UX1-101 claims that there is no connection on pins 4,6&7 for the EDID eeprom, it seems that this panel does indeed support an eeprom(?).

Whew! Got my order in just in time.

Received my panel today. It was brand new and well-packed, just as advertised. I'm still waiting on a lid assembly to put it in, so I haven't tested it yet, but I'm very worried. There is not an IBM part or FRU # to be found anywhere on this thing.

I "upgraded" from a some years old SXGA+ LG/Philips IPS panel to a brand new UXGA BOES with -101 on the end IPS panel and I don't see a big difference. It's even hard to find a small difference. It is slightly brighter. The contrast is around the same.

The -100 and -102 Boeys panels fit into the T60. I tried it with the -101 and it fits, too. This maybe because of some additional information stored within this panel - I do not know.

This is not encouraging.

I have to admit I never really liked the thinkpads flexview displays so much. I much prefer my EIZO displays I am very used to. Being not so satisfied with the SXGA+ LG/Philips panel I tried to get the "best of the best", the BOES UXGA. The -100, -101, -102 do have slightly different color schemes (RGB mode changes) but I am not familiar with all this talk.

The new UXGA display (-101) has a much lighter white which I dislike. It is not healthy to look into this light white. My EIZO has an extra setting for displaying web and text content: in these cases the display changes to a more yellow color scheme. So it is easier on the eyes. Try to look in the sun or something other very bright and you notice some effects on your eyes Once I see a movie or display pictures on my EIZO, it changes back to RGB so I see all the colors.

I'd like to change the bright color scheme on my BOES -101 back to a more yellow level, I just do not know how to do that.

Just out of curiosity, what Eizo monitor in particular?

Generally, look for ways to change the "color temperature", i.e. modify the white point. I didn't check, but I believe the Hydis screens are set to meet D65, i.e. 6500K, which is the same white point for the sRGB color space.

In catalyst control center, a setting for this should be available (it used to). Alternatively, Powerstrip can also do this in Color profiles -> Configure -> Temperature, or select one of the many presets from the drop down box.
When screens are new (including desktop monitors) they perform close to the 6500K color temperature. But as they age, they turn more and more yellow causing a warmer "look" to the colors. Professional photo editing displays feature a light sensor which is built into the panel, which measures light output and change in color temperature.

I don't use a dedicated gpu. I have the intel 950 gma chip. Only this way my notebook is completely silent as it does not use any fan.

I use an Eizo S1910. Great for text mode. Great for browsing the web. The newer EIZOs are junk, I have used some, but they tend to have problems being silent or their panels shines too much, as the boeys ones do.

This is much better. I like my whites to be white, not yellow.

goofyGAguy wrote:This is much better. I like my whites to be white, not yellow.

There is not one true white, and our perception varies depending on surroundings.

I've posted some pictures in the past where the same screen can look bluish compared to another, and greenish compared to a third.

Compare, say, fluorescent to incandescent to sunlight.

When you say you like white, not yellow, you probably mean that you like blue, not yellow. Which is OK and quite common.

ssd_thinkpad wrote:The new UXGA display (-101) has a much lighter white which I dislike. It is not healthy to look into this light white.

Doesn't it simply mean that the display is brighter? Won't reducing the brightness negate the effect?

If you want to do photoshop or edit videos, a srgb calibrated display is the best. But when you want to read text, a more yellow display is just healthier to your eyes.

As an example:
- try to read a printed paper
- and then read on an old school overhead projector. Your eyes will burn.

Because of that EIZO has put a "text mode" into all their monitors since years. Just decreasing the brightness does not help in the -101 boe panel as its contrast is not so good. If I reduce the brightness, the black is just not deep ("black") enough. I am happy to use the T60 as I would definitely very uncomfortable with other notebooks From what I saw on the x301 there are huge quality differences in notebook displays.

ssd_thinkpad wrote:- and then read on an old school overhead projector. Your eyes will burn.

And you say that it is caused by the color tint, and not just by the fact that the projected image is far brighter compared to the surroundings?

I was worried for nothing. This screen is beautiful.
