Looking for recommendation on 3 pieces of eval kit hardware for LVDS driver

[Blowthar]

I am working on a fully hackable television controller (serial port uploads new OSD glyphs, commands control large flat screen. The hardware is intentionally dumb. You bring the brains. All open source and hackable) The end goal is to attach to a large screen TV's t-con board and replace the brains.

I have the middleman almost complete, which is the OSD compositor over the (zero-ish latency) output stream.

I am targeting 1080p at first as I can find serializer and deserializer chips.

My architecture goal is:

DP/HDMI/DVI... deserailize to 24-bit RGB -----> FPGA OSD compositor, input mux select, picture/volume constrol... ---> 24-bit to LVDS serializer.

I have the verilog for the OSD compositor section nearly finished.

I figure I can build the board itself for $20 to $50 worth of components in low volume, however in the meantime I need some eval hardware.

For the speed necessary, I was looking for a deserializer/serializer eval boards with mezzanine connectors and a powerful enough FPGA dev kit that can handle the RGB stream's signal integrity at ~150 mhz.

I figure the test hardware will be about $1000 to $1500 so I am trying to budget something less than that if possible.

Real-time OSD compositing confirmed in verilog simulator (Wow that thumbnail is tiny)

Why deserialise / serialise outside the FPGA? Just use an FPGA which can deal with HDMI input. Almost every FPGA out there supports LVDS output nowadays so you can hook up almost any panel.
