🔧 HDMI VGA LCD Screen Controller Board for LP140WH1 / LP140WH4
I bought this controller board to repurpose an old laptop LCD screen (LP140WH1) into a secondary monitor. The idea of DIY-ing a functional external display instead of tossing it was just too tempting—and the price on AliExpress was unbeatable.
What pulled me in? The board supports both HDMI and VGA inputs, which I knew would give me flexibility with my current desktop setup and retro gaming consoles. It looked simple enough for a hobbyist with some soldering experience.
Experience using it: Once it arrived—surprisingly quick shipping to the US in about 10 days—I hooked it up, connected the 40-pin LVDS cable, and powered it with a 12V adapter. The board recognized the screen right away. No configuration was needed. The picture quality was clean at 1366×768.
Pros:
-
Compact and easy to connect
-
Clear, bright signal output
-
Included speaker connection—didn’t expect audio!
-
Works with multiple screen models
Cons: – No mounting holes or bracket—had to DIY a case – The included cable was a bit short – Instructions were basic (YouTube helped)
Price vs. US alternatives: This board was under $15—compared to $30–$40 on US DIY sites. Major savings.
Did it meet expectations? Yes, and more. Honestly didn’t think it would fire up that easily or output such a stable image.

Final Thoughts
Honestly, I didn’t expect all 10 of these AliExpress items to work this well—especially considering the price. I was cautious going in, but every product met or exceeded my expectations. Shipping times ranged from 10–15 days, which was faster than I anticipated. I’m genuinely impressed by the quality of these DIY electronics parts and screens.
I’d definitely recommend these to anyone looking to repurpose or build screens, monitors, or embedded projects on a budget. I already have a wishlist full of more components to test and build with. If you know what you’re buying and match screen models carefully, AliExpress can absolutely deliver.
