Introduction

Upgrade the LCD in your Thinkpad T520 to a quality 1080p panel.

The T520 is available from Lenovo with a 1080p high color gamut display as a $250 upgrade to the standard low quality display. The exact same 1080p LCD panel Lenovo uses is available online for under $100 and is easy to install yourself!

  • The victim. Any T520 will work with this upgrade. Even the most basic configurations can take advantage of a top of the line display. The Thinkpad T510, W510, T520, W520, T530 and W530 will all also work for this upgrade.

  • This display is more capable than the average LCD so if it is adjusted wrong it can be very obvious.

  • To simply make the screen look good for viewing images and office use, Windows has a built in Display Color Calibration utility that allows adjustment of the color balance of the display. The Intel IGP software can also be used to make adjustments instead. Right click on the desktop and select Graphics Properties...

  • It is also easy to experiment with color profiles others have created for this display. Every panel will be slightly different but it is possible to find a profile that looks good on your screen. I found that the first ICC profile provided by Sager works for me.

Successfully changed screens on a Lenovo T530 from an original 1600x900 to the 1920x1080 make and model mentioned in this guide. I was able to check the difference in quality of the two displays directly running side by side my W520 which has the 1080 and the T530 with the the original screen that I ordered for my father in law. The 1080 is a better screen altogether. And as this guide shows, replacing the screen is really easy - a no-brainer.

Are there fitting differences in the B156HW01 V.4 and the V.5 or V.7? Most places I look the V.4 is out of stock or discontinued.

Successfully installed on a Lenovo T520 with an original screen resolution of 1600x900. The new, higher resolution screen was easy to fit, and worked straight away - no need for a new cable or anything like that.

Thanks a bunch. Used this guide to replace a full display and hinge from a rather aggressive "drop". Trickiest part is the cable reinsertion - with the sticky tape underneath the original cable install it is a little finicky to get a snug and flat fit.

Best,

Very nice guide. One question to be save: wil a upgrade from a standard 1366x768 screen also be possible? I read elsewhere the motherboard or cable wil not support an full HD screen.

Replaced a 1366x768 in a used T520 that I bought a couple of months ago. works great, only difference from the guide was I had 3 screws on each side of the metal frame The 3rd picture on step 7 shows a threaded hole where I had a screw
