Parts required for overclocking LG IPS panels?

RE: Parts required for overclocking LG IPS panels?
I have a Dell U2711 and I broke the LCD panel after a shock on the screen with a cupSad It's the most expensive espresso of my life!

I called to Dell and they asked me 900 euros for a refurbished panel!

At the beginning, I planed to buy a new LG panel LM270WQ2 but the part is difficult to find, and the prices are high...

After some researches I found:
- the LM270WQ1 which is less expensive and easier to find because more Apple monitors was sold compared to the Dell monitor.
- the LM270WQ3 which is used in other monitors

Here is my key interrogation: can I plug in my Dell U2711 the Q1 or Q3 panel ?

If so, what kind of manual adaptations have I to do ?

Please note that I am not concerned if I lost some functions of my screen or if the final performances are a little but lower.

Regards,

Benjamin

Supposedly the timing controller is interchangeable between the LM270WQ2 and the LM270WQ1, but the LM270WQ2 has CCFL backlighting while the LM270WQ1 has LED backlighting, so I don't know if the backlight control is interchangeable. Even if it worked, the LM270WQ2 is a wide gamut panel while the LM270WQ1 is a standard gamut panel, so the colors will look different. I think you're better off just getting a new monitor like one of the Korean 2560x1440 monitors on eBay.

Well after many months of search, failed purchases, etc. I have finally got the required parts and managed to OC my Shimian to 120Hz! Big Grin
I uploaded the frame skipping test on You Tube, @ToastyX what do you think?
Are those 120Hz valid?
It may be capable of more than that but my 290x i struggling to achieve constant 120 fps already.

Definitely looks like real 120 Hz.

Hi Miskonius,

Could you please tell us where you got the correct parts from (and what they were).

Any help would be greatly appreciated

Thanks ToastyX!
I even managed to get it up to 130Hz, frame skipping test looks OK it works fine in games but I am getting a lot of flashes when browsing so I left it at 120Hz.
I tried 140 Hz but for some reason Windows is refusing to accept it.

You need:

Logic board
LM270WQ1-SLA1

Driver board
LM270WQ1 /LDK-LE256/HY-2560M

You can get them at overlordcomputer.com for $200 OC PCB set or you can try at on Chinese taobao.com and use yoybuy.com to purchase it for you.
I bought driver board from overlord (~$90 with shipping) and logic board from China ($50 with shipping) which ended up $140.
You can only buy the driver board at overlord since the guy who sells them in China sanelin88 does not respond to messages.

Damn I guess you are right.
Talk about a last minute purchase on my part. Big Grin
Ask sanelin88 over here http://en.agreetao.com/item/37901630265 he might answer.
It occurred to me that he might be ignoring yoybuy because he knows that its for foreigners for which he charges extra.

Thanks once again Miskonius. (Great info and help!)

Do you know where to get the original Driver board from (the non 100hrz DVI board)?
