Upgrade T43 SXGA to UXGA using T60p LCD

[osse99]

Hi!

I'm into upgrading my 15" T43 (2668-92G) SXGA to UXGA and have found two different LCD's:

- T43p (IDTech N150U3)
- T60p (BOE-Hydis HV150UX1)

Have ordered a 91P6893 UXGA cable already.

- Is it possible to use the T60P LCD?

- Which one is the "best" choice (same price)?
According to http://www.thinkwiki.org/wiki/TFT_display the contrast is a little bit better for the T60p display.

Hi!

I bought an UXGA LCD assembly from a T42P and have done a successful upgrade.

I'm very satisfied, the higher pixel density compared to the SGXA+ screen is really something that makes a difference, its like a new laptop!

The LCD is nice, almost as good as my A31p screen (well, after 5 years daily use its a bit yellow and have some darkish spots, but the viewing angle and sharpness is still better than the T42p LCD).

Still thinking about the T60p UXGA LCD, is it any better than the T42p LCD or should i just forget about it, relax and enjoy my new setup?

I have a T42p with a 15" IDTech UXGA IPS screen. I have just successfully sidegraded the T42p with a new T60p 15" BOE-Hydis UXGA FFS screen (13N7194). The sidegrade was a simple drop-in replacement process - inverter was not changed.

I changed the screen because my T42p at 3 years + 1 week (!) suddenly started becoming pink on cold starts. Originally I was going to try replacing the CCFL tube, but bought the T60p panel as a backup measure.

Unfortunately because my old IDtech screen has become fairly dim (MonacoOPTIX reports 75 cd/m2 at max brightness), I can't give any comparisons on brightness or viewing angle. My new BOE-Hydis screen's maximum white luminance is measured at 175cd/m2.

Observable differences are:

1. Backlighting evenness - IDTech screen had large dark patches extending from two lower corners due to uneven backlighting. BOE-Hydis screen has small dark triangles at two lower corners but they only extend inwards 10 pixels. Also, IDTech screen had significant light leakage at the bottom and side edges when display was all black (i.e. for movies). BOE-Hydis screen has no light leakage at edges.

2. Power consumption - BOE-Hydis FFS screen uses 1W less than IDTech IPS screen and this is verifiable when running on batteries in Battery Maximizer's Battery Information. When running on medium brightness and low WLAN activity, this adds about 7% to battery lifetime!

3. Pressure marks - IDTech screen was very sensitive to pressure - pressing on the screen caused highly visible ripples of color extending for an inch or two. Pressing on the BOE-Hydis screen does not cause rippling and at most some slight brightness change directly where pressure was applied. Although my IDTech screen did not have any permanent pressure marks, I have seen units that exhibited pressure marks in the middle of the screen, presumably generated by contact with the LCD lid.

4. Color correction - Using MonacoOPTIX 2.0, I could achieve low color errors with IDTech screen (ave 3dE), but with BOE-Hydis screen the errors are larger (ave 6dE). Supposedly this BOE-Hydis screen is sRGB - this might be interacting with my color correction software, but I'm not experienced enough on this front to understand what's happening.


Personally, I would only change LCDs if your existing LCD is losing brightness due to age or if you are a perfectionist. Otherwise both screens seem very crisp and enjoyable.

I have done the same "upgrade" as user14159. I replaced the ID-Tech UXGA panel in my t42P with a BOE-Hydis UXGA for a t60P. I couldn't be happier. I find the BH panel to be a bit brighter, noticeably better contrast and very white whites. The ID-Tech had a slight yellow cast to the whites.

I used the cable and inverter that was in my T42P, only replacing the panel itself. I believe the 15" t42's that came with an SXGA+ panel use the same inverter as those that came with a UXGA panel, so in theory you should find the same success as I by going to a UXGA from an SXGA+.

skuff - Congratulations and Welcome to the BOE-Hydis UXGA club!

Thanks Peak2Peak! The LCD panel is the thing about my laptop of which I am most picky. I am a complete perfectionist in that regard. I have looked at many different LCD's over the years and have decided that of the options available today, even considering some of the high-res 17" panels, this BOE-Hydis UXGA is my nirvana.

After I bought and installed this one successfully, I even bought another one as backup as they are getting harder to find. Should my t42p ever kick the bucket or get too outdated, I can always find a used t60 15" and take my panels with me.

Hey guys...and thanks Peak2Peak for leading me to this thread...

Here is what I wan...no, I NEED to do. lol...I have a T60p w/BOE Hydis 15" UXGA. I bought two additional BOE-Hydis screens, so I want to get either a T61(p?) motherboard, and put it in my T60p "shell" with the S-IPS screen hovering above...

Alternatively, I am thinking to maybe buy a T61 14.1" and put the BOE-Hydis screen on it, replacing the junk screen that's wobbling over it. lol...Come on guys...I have a Penryn T9300 that needs a home on a mobo. I can't stand looking at it in its little box anymore. I have silver paste ready...This would so be the ultimate Thinkpad!!

And who is the seller? And how much are you guys been paying for it?

[Peak2Peak]

skuff - Yep! agree with you 200% for buying in another BOE-Hydis UXGA as a spare, exactly what forum member Crunch has done and what I am proposing to do soon - they very scarce these days and NOS are disappearing fast

My previous T43p had an IDTech UXGA panel which was a great introduction to the "FlexView" game - but after owning the T60p with the BOE-Hydis panel where colours seem to be more vibrant and sharper, I can not help but use it as a reference to judge other panels etc. (Am I a bad person?)

cmarti - Try ebay seller BLISS-COMPUTERS-LCD-SCREEN-STORE
