content: Looking for a friend as they have bought an infrared camera for there gun and they want to make a screen for it, the camera resolution it outputs is 1020x596 (PAL) or 1020x508 (NTSC)we don't mind if it is just a screen and controller board as we can make a box or a kit like the camera car ones. Trying to find a high resolution to mean that the infrared camera is not limited.If possible ebay (looked the best i could find was a 800x480 but don't know if that is a limitation of the size as if the screen size is only a little bit bigger but a higher resolution it would be possible to change the screen size)

content: Screens with such high resolution in such a small physical size are extremely rare and almost certain to cost a huge pile of money if you can even find one. IME, there are no such screens available at reasonable prices.

content: High-resolution viewfinders are still quite rare. I'm not even sure the Sony HVRZ5U viewfinder has full resolution.If this is for a rifle, etc. you could consider a camera-type eyepiece type viewfinder (vs. a larger screen). For example you can get the viewfinder for a BlackmagicDesign URSA camera that has full 1920 resolution...http://www.bhphotovideo.com/c/product/1137318-REG/blackmagic_design_cinecamursanevfp_ursa_viewfinder.html

content: The Sony HVRZ5U has two viewfinders:An eyepiece viewfinder at 852x480A 3.2 inch screen at 1920x480I don't believe there are ANY "4K" viewfinders.Ref:http://pro.sony.com/bbsc/ssr/product-HVRZ5U/

content: Your best bet is probably to get a replacement LCD for ~4" inch smartphones or buy a cheap 4" smartphone and rip out the screen. I'm not aware of a screen smaller than 4" that has at least a qHD resolution.Here's an example:http://www.ebay.com/itm/Screen-Display-LCD-Module-LG-Optimus-L7-4G-P875-F5-4-3-IPS-qHD-New-ORIGINAL-/161148943447
