It wouldn't be the same panel...you said it yourself, smaller screen and lower resolution.

If you want a low-res monitor just go nab one from Newegg or something for 200 bucks. You can watch slickdeals.net for some e-ips 1080p screens. They are cheap!

ScribbyDaGreat: Really looking farward hearing what you find out! Lets hope its possible to change the board in the Non-oc version. and that we can buy that board and mod the non-oc's ourself.

I was probably one of the first to report the new Catleaps having issues with getting over the 60hz range barrier (Mine only goes to 62hz).

Three possible reasons that I can think of for the change from from 2B to 2C is that:

a) Maybe the manufacturer discovered a flaw or some issue in the old controller.

b) Wanted to cut some costs and use cheaper components.

c) The old circuitry isn't available anymore or at least not in the quantity to meet demand any more.

In any case, since I have around 4-5 dead pixels, the seller has agreed to take mine back and pay for the shipping as well, which surprised me. Maybe I can get a 2B panel if he has anymore. Hopefully in my previous statement, the reason for the switch wasn't option A.

When paying, I asked if it was possible to have the screen checked before shipment (this was before the change in listing), and have not gotten a reply.
Id like to have mine checked and verified to be pixel perfect and defect free before shipment.
Thanks you

Hi
thank you for buying
I am about to send your order and just noticed the note.
we don't open a box to avoid an argument about the condition ( new or not ) ,sorry
there might be some dead pixels ( five at most )
if you don't want this monitor , I can cancel the transaction without any penalty
waiting for your reply
choi

Conitinued,

Me

I would rather it be opened and inspected to avoid having to ship back. I want it regardless. If it has more then 5 bad pixels does that mean its DOA and return shipping would be covered?

Quote:
sorry, I can't open it although you ask me to do that, sorry it is our policy and ebay's also
if you worry about the bad sector , I recommend you to buy the perfect pixel ( confirmed by yamakasi company )
I will give you discount if you would buy it

thank you
choi

So its not him checking the box, its new from the company with guarnteed perfect pixels. I wonder if thats the same panel as the U2711 then?

Great service. Who did you buy from ?

Here goes all the pics from an OC monitor.  Not so sure we could swap out internals since the PCBs on the panel itself seemed to be glued (and to me look like they have some funky attachments).

 

IMG_1352.JPG

 

RED for the PCB to the panel, BLUE speakers, YELLOW to brightness/volume/power, PURPLE to panel.   THIS IS THE DVI TO PANEL PCB.

IMG_1351.JPG

 

UP CLOSE OF SN ON DVI PCB

IMG_1353.JPG

 

FULL OF DVI PCB - CABLES WOULD NOT COME OUT EASY AND I DIDN'T WANT TO DAMAGE THEM

IMG_1354.JPG

 

BACK OF DVI PCB

IMG_1355.JPG

 

UP CLOSE OF DVI PCB TO PANEL PCB CONNECTORS - THESE ARE NOT THE SAME AS ON A NON-OC MONITOR

IMG_1356.JPG

 

RIGHT SIDE/TOP OF PANEL PCB

IMG_1357.JPG

 

CENTER PANEL PCB - THIS IS WHERE THE PCB DVI CONNECTORS PLUG INTO (UP CLOSE SHOT BELOW)

IMG_1358.JPG

 

UP CLOSE OF CONNECTION TO TOP PANEL PCBS

IMG_1360.JPG

 

 

UP CLOSE OF CHIP

IMG_1362.JPG

 

HERE'S THE MAIN DIFFERENCE BETWEEN THE TWO PANELS - THESE ARE THE CONNECTORS THAT LEAD TO THE DVI PCB

IMG_1359.JPG

 

LEFT SIDE/TOP PCB ON PANEL

IMG_1363.JPG

 

SN on the other PCB is 68705-0922A rather than 68705-0921A and is "SOURCE PCB (R)" instead of "SOURCE PCB (L)" - this is the left side of the monitor when it is flipped and you are facing it.

IMG_1364.JPG

 

Again, I am not sure how one would remove the boards on the back of the panel to make a switch.

I just got my Catleap Q270 last night; SE2C variant, and it won't hit refresh rates above 65Hz or so without wigging out. Otherwise it's a fantastic monitor wink.gif

Looking closely at the (very nice shots, thank you jbuschdev) pics posted so far of the 2C variant compared to the couple photos ScribbyDaGreat posted of the wiring at the back, it would appear we have a total of 3 components to worry about here.

1. The actual panel itself, including a couple thin PCBs that directly drive the TFT. I suspect this is the same in all cases.
2. A driver board located immediately below the two thin PCBs. This is clearly visible on the 2C shots and not shown on Scribby's 2B shots because he didn't remove the metal shield covering it (although you can see the cables that attach to it). This is connected to the two thin PCBs with a couple flat ribbon cables (at least on the 2C). I suspect this board is connected to the two thin PCBs the same way on all units.
3. A DVI converter board, which takes the incoming power and DVI and feeds the drivers/backlights, etc. This is obviously a different board on both units, as the wiring is different.

My current suspicion is that both the DVI converter board and the driver board are different between the two variants; they have different cabling that runs between them, so this stands to reason. It should be possible to replace both the dvi converter board and driver board from a 2B onto a 2C's panel and get high refresh rate out of it.

ScribbyDaGreat: When you're doing a teardown could you remove the metal shield covering the driver board (the one clearly visible in the 6th shot of jbuschdev's pics) and examine the connection between the driver board and the panel (two flat ribbons in his case)? If your connections there are the same, there's no reason you shouldn't be able to replace the driver board and DVI converter on your 2C monitor with your 2B's hardware and get high refresh rate out of it. This would be extremely invaluable, and would tell us exactly what's the difference between the two units.

EDIT: Just saw your shots Scribby, thank you; is it possible to swap the board attached to the back of the panel marked "LG Display" on the main chip? you should be able to flip the tabs up on the two ribbons and remove it, and put that part (and its associated DVI board) from the 2B into the 2C.
