Is 1600x900 possible over single channel LVDS?

Yes very easily, did you check it before doing the swap?

 

Unfortunately I can not tested the new screen, but with the old one it works perfectly.

 

Sorry to revive a necro thread, but I'm looking for info on a very similar topic.

I have a Latitude E6430. Mine came with a 1376x768 over single channel LVDS, but there is a 1600x900 model (which requires swapping out the single channel LVDS for dual channel LVDS).

I have purchased the cable and the screen, and will be upgrading soon. But I was really curious about the possibility of putting a 1920x1080 screen in.

I have had kind of a hard time finding an LVDS 14" 1920x1080 screen... And I don't understand the difference between 40pin and 30pin...

I wonder how applicable this is: Replacing T430 screen with a better one - ThinkWiki

I read on one ebay listing for a replacement stck E6430 screen that the connector was 40 pin, so I've been going on the assumption that they were fundamentally different connectors, but this thread seems to suggest differently. But I'm a bit in over my head.

But a lot of these cases are a lot more complex than mine. Should my laptop be able to support a 1920x1080 screen from another laptop, just PnP?

Any reading material or advice is hugely appreciated.

 

You need a screen with the same pin count connector (probably 40?) as your new cable, dual channel lvds can handle 1080p.

 

In theory you should be able to to 1080p over dual channel LVDS, but as you are finding out there are basically no 14" 1080p LVDS screens. All of the 14" FHD screens I've been able to find are 30 pin eDP, which is a completely different signaling system that is incompatible with LVDS.

The best 900p LVDS you're going to find is the X1 carbon screen listed on that wiki, but while the signaling is compatible there's physical incompatibilities that will make it hard to install. The wiki and related threads have good info on the physical problems you'll have to overcome.

If you don't need full sRGB gamut or a matte screen, I'd recommend looking at the B140RTN02.1. It should be fully compatible, and has better viewing angles and contrast than most. I believe this was the screen used in Alienware m14x R2, so check out reviews for that.

 

Ah, interesting.

So does 30 pin = eDP, 40 pin = LVDS? It had seemed to me that there was 30pin LVDS and 40 pin LVDS...

Does the existence of this change anything? Sct 40pin To 30pin Led To Lcd Converter Cable - Buy 40 Pin Lvds Cable,Led To Lcd Cable,40pin To 30pin Led To Lcd Converter Cable Product on Alibaba.com

 

I'm in a similar situation: I would upgrade my Aspire 5920G from 1280x800 to 1920x1200. I bought a LTN154U2, same 30pin and backlight layout, but later is a 2ch lvds so when I tried I got a black screen, no image, but backlight is on. I have both LCD pinout datasheets, view attached media.

@triturbo: can you give me some advices about right cable to use or one I can adapt? Maybe an original Aspire 5920G one to mod, changing LCD pins positions?

 

Check this out: http://forum.notebookreview.com/threads/5920g-lcd-upgrade.691179/#post-9084482
Most of the info can be found on the first couple of pages, and this is direct link to the pinout.

 

@triturbo: Thank you for your advices. I found LVDS mainboard's connector pinout at page 18 of this document: Aspire 7702 mainboard LA-35551P's schematic http://www.rom.by/files/icl50_mb_la-3551p_r20.pdf. I will do remove all pins, like with a molex connector, and reassemble it to follow layout in Excel file you linked in previous post. Can you confirm 7702 cable has same plastic connector on mainboard (same dimensions) of Aspire 5920G? Or I must use the original one of my Aspre 5020G, disassembling my own and use it as replacement cable mainboard connector?

 

Yes it is the same. It was long time ago, but I think that only pin rearrangement was needed.

 

I have a lenovo z570 with a 1366x768 screen(1ch 6bit lvds interface). I got a 1080p screen LP156WF4(SL)(B3) which uses a 2ch 6bit lvds interface. It recognizes the resolution but the image is very distorted. Is there any way to fix that? or it this due to not having support for 2ch? I have included an image.
It looks as if the screen is cracked, but it only looks that way when the image contains multiple colors. If I display solid colors, it looks uniform but the colors are completely off.
black looks red,
red looks orange,
blue looks purple
green looks pink,
white is proper though.

 

That screen *IS* damaged. No way around it. You may not physically feel the cracks, but it clearly is damaged. It looks like it got stepped on with someone's heel.

 

I just found this thread and had already posted about wanting to put a 4k panel on my laptop that has dedicated graphics when they come out. I guess this LVDS would be the limiting factor.

Is there a resource that explains how LVDS works in simple english since I am not an engineer.
