![]() Let me review the final material sources: Luckly, the painful experiments were worthy to make this so-satisfactory 4k beamer. I tried to build my 4k beamer with the LCD, and tested many lenses. If you have problems, you will have the problem forever as there are not many alternative materials.įinally, I could get a 10.1" 4k LCD with a proper driving board. Lens limitation : the lens combination to be used with 15.4" LCD is limited.Also the throwing distance would be limited. Size limitation : if you go for 15.4".In addition, it works only with some specific VGAs. It uses DP cables, and the length is limited. To be straight, all the boards are garbages. Poor driving board : In, several sellers sell the boards.However, there are many obstacles in the usage of 15.4" LCDs. It's been around one year since I had a plan to make a 4k beamer.Īt first time, I tried to use 15.4 inch 4k LCD as there are several taobao sellers selling 4k boards to drive the LCDs. I hope this instruction may be helpful to someone wants to have a 4k beamer. You can make this 4k beamer rather easily using my AutoCAD drawing files and this instruction. To save your money, I've done many experiments (tests) instead of you guys. I like to build something new by myself.Sorry to guys who followed my 2k builds so far! I haven't used my DIY 2k beamer, but used my DIY FHD beamer due to several issues it has poor brightness, the only media source is PC, and 2k resolution is not commonly used.Want to watch Neflix in 4k resolution!!.Anyway, the 4k beamers are way tooo expensive for me. The another type of 4k beamer uses so called "e-shift" technology, but it is not physically 4k. In the current market, commercial "real 4k" beamers are only made by Sony, and the price starts at 9,999 USD except the discontinued models. ![]() Here, the 4k means "3840x2160" resolution (called 2160p) upto 60Hz. in my English blog : go to my English blog.The original post is in my Korean blog : go to my Korean blog, and.I want to share my newest build: A DIY "real 4k" Beamer.
