Anyone interested in a Hi-def (1920 x 1200) mod for PB/MBP?

changed MBP WUXGA

It's screenshot.

use SwitchResX.
1920x1200@56Hz redirect to 1920x1200@60Hz.

What would you like to know? There is a great deal of ground to cover on this topic so what would you like to know first?

Around the middle to end of last year I got very sick and tired of waiting for Apple to release a Hi-Def PB. When I recieved a non working one as a gift I got to work trying to figure out if I could make one myself - there were afterall Hi-Def notebooks available but Apple didn't make one. I managed to source a Sharp panel from ebay that was from a Dell. Set me back AU $149- I recieved it and found 2 things (I only bought it as a project) the first was that the connector for the lvds cable was too big and that the display was a 15.4 not a 15.2 as fitted to PB's of the time. Some 8mths or more later and a great deal of mucking about and some very handy Apple anouncments it's almost finished and I'm about to embark on my next project of a 12" PB based tablet (I've gotten sick of waiting for those too.). So if your after more details on how to do it yourself let me know.

If you do a 12" tablet, how are you going to get the touch screen into the computer? What about a small USB ready microcontroller with a couple A/Ds? A PIC from microchip could do this. You could run the usb wires right to the usb bus on the motherboard. I could help with microcontroller code or osx driver code.

Did you have another idea?

Color me impressed.
Maybe SwitchResX somehow works when DisplayConfigurator fails.

Sadly, I've still somehow butchered any chance of things working at all with some ridiculous settings in the EFI that won't reset. Still can't get the 1920x1200 display even working in Windows.

Maybe I'll give SwitchResX a try this weekend to see if I can replicate the results with my panel.

In the meantime, if anyone can replicate these results with a different panel or the same panel, I'd love to hear it!

- Tim
 
This makes it very tempting to take the plunge. I'm going to wait though to see others try it. I'm not financially well off enough to experiment like this.
 
Finally some success. I will have to seriously consider a MBP now. Fantastic work belldandy!

If I'm not mistaken switchresx works in a different way to display config X in that it re-routes display res/freq to existing resolutions where as DCX adds new res's. I was under the impression that earlier Tim tried a whole heaps of refresh rates with his panel. Anyways maybe 56 is the golden number.

HooRaaaaaaaah!

I've been thinking about htis one for a while now and I thinnk I want to use a pressure sensitive tablet ie wacom. Wacom do most of the tablets for PeeCee tablets (too many tablets in there). I had thought about using a passive touch screen but I'd want Inkwell etc to work and I'd want it to be precise. I am actually considering turning my 15" as seen in this mod into the tablet but haven't decided yet. I plan to experiment by building a display (stand alone) with a wacom T built in a la cintiq. Thanks for the offer and I may take you up on it - just not yet.
 
I'll have to mess around with these two programs on my MBP once it arrives... :D

Cheers!

I did try a whole heap of refresh numbers =p
They just apparently don't work with DisplayConfiguratorX but do with SwitchResX.

Stupid me... should have tried SRX. Now... I wonder if my panel will even work with SwitchResX now that I *somehow* managed to make it all ridiculous (vertically interlaced) in Windows...

Yeah that'd be fun. You'll definitely need some kind of driver software. Hopefully if you went with something like a wacom it might have an interface already on it. We just want to go with usb if we can so we know we can hook it up inside the computer. You don't want any wires hanging out. :)

Well Wacom make a lot of digitizers for tablets for OEM's but they also make their stand alone tablets (I don't know why I felt I needed to explain that). If you look at a 12 x 9 tablet it is exactly the same dimensions as a 15" 4:3 LCD. Now the good thing about this is the the tablet has the controller already and drivers for OS X :eek:

Now the digitizer in the wacom tablets is virtually identical in design to those used in tablet PC's except (and this is the kicker) the board that they are printed onto are bigger than those used in a TPC. So for example I have a 6 x 8 Wacom but the board for it is too big to fit withing the confines of a 12" PB. Furthermore there is only 10" of active area. Now on a desktop display you have all the surround of the bezel to hid the excess board behind so that is where I was planning to start.

I have a 15" Apple studio display (old blue and white one) that I was thinking of playing around with for it. But I would like something in a bit higher res so I have been looking at my Thinkpad A31P with 1600 x 1200 15"er in it and am contemplating ripping that one out and seeing if I can't make it work. All the boards on the back of the display need to be displaced in order for the tablet to work all over but it is do-able just look at the projector DIY'ers for inspiration.

I probably shouldn't always be giving away all my secrets but eh.. who cares right?

Oh and Tim, er I mean er... Mr Banned. I really hope you manage to get you're display sorted now too as you have been the longest running person on here trying to get some results and I really commend your efforts. Ddn't you get your LB replaced recently? Shouldn't that have fixed the EFI prob?

Nope... they rejected my repair because they claimed the case was "misaligned" (i.e. coming apart... their fault, I might add) when I "changed the hard drive" (I left out the parts where I changed the thermal paste and the screen). This case misalignment, they claim, is the cause for random shutdown issues. That's a load of crap, of course.

Luckily I went in under the hood once more and fixed the RSD issue myself. Moving some tape from above the thermal sensor's wire to below it... You'd think Apple would be a little less stupid than that, but hey...

I'm considering one of two routes, really. One is selling this one on eBay and footing another $700 or so for a C2D MBP... The other is getting a new topcase for this one and just trying to be content, haha.
 
Question: I'm looking at an WUXGA LCD on eBay that has no inverter. Would I be able to simply disconnect the inverter on my current cracked, but otherwise perfectly backlit panel and use it on the new LCD, or are those things LCD-specific and I'd need to order another one?

You don't need the inverter. Just the LCD with backlight. The inverter simply powers the backlight and the connections are almost always identical. Please have a look at the photo's throughout the thread to make sure they are compatable with the panel. Remember this has only been shown working on 1 MBP so it is not exactly proven but you have much better odds now than a week ago.

Maybe you can give me a short hint how to solve a strange problem after replacing a broken display in macbook pro 15".

attachment.php


I bought a replacement panel at eBay and my local apple dealer replaced it. The strange behaviour of having a split screen (see photo) appears sometimes after having used an external monitor.

The Vendor ID is 6AF and Product ID is 1974. I have alredy tried out any combination of copy and replace the files in the overrides folder even with replacing the hex vaue and so on. But this only changes resulutions but not this damned split screen.

Sometimes it works with 1280x1024 resolution and full (non split) screen, sometimes I have to PRAM reset a dozen times until I finally lucky after hours. But it has never worked with 1440x900 as it should.

After PRAM reset the boot logo appears normal, just before the login screen of mac os x appears the "four screen split mode" starts.

As you probably can imagine this makes me mad. So any hint is appreciated.

Thanks and regards,
Horst Schmidt

If an Apple Repair center fixed it... take it back to them and tell them the problem. I've never seen something like that before, so I don't know what to tell you.

Have you tried booting off the restore dvd to see if it might be a problem with your install?
