Looking for an affordable monitor for 4K cameras
 

Looking for an affordable monitor for 4K cameras below US$250.I need 5 or 7 inch,resolution no less than 1280*800,IPS panel will be better.
I just need HDMI and AV in,no need HDMI output..
The 4K UHD 2160p format should support 60/50/30/29.97/25/24/23.98.
If monitor is with light weight and slim design,that will be great.
I want software functions such as:Peaking Focus,Check Field,Pixel to Pixel ,Image Flip,Image Freeze,etc.

Does anyone know what brand monitor I can buy?
My friend recommend me a feelworld 7 inch monitor FW74KV2.It seems it is nice.Does anyone try this monitor before?
