The HDO2’s have an IPD adjustment range of 54mm – 74mm, making them more universal for those with narrower and wider set eyes. This has been a problem in the past with Fat Shark goggles with an IPD adjustment range of 59mm – 69mm, but they have worked to correct this. To appropriately merge two screens into one, the lenses have to be centered on your pupil in each eye. This is the distance between your eyes, and it’s important to be able to adjust this for each individual user. This comes down to the difference in distance from the front optical lens to the screens.īeyond the FOV, there is the interpupillary distance adjustments, or IPD. The Fat Shark HDO2 has a 46° FOV and the ORQA FPV.One has a 44°. There is a very slight difference between the two as shown in the graphic below. Despite having the same screens, difference in the optics can affect things like field of view (FOV). It’s evident from the moment you put the goggles on that there is a difference in how each company has approached the construction of the optics. Also, both the HDO2 and the FPV.One are capable of switching from 4:3 screen ratio to 16:9. The ECX337A has a resolution of 1280 x 960 and the OLED screens deliver better blacks and a much better contrast ratio over traditional LED screens. Unless you’re using a full HD system, the better displays would be all but wasted.īoth Fat Shark and ORQA chose these screens due to the supply cost and the great specs they offer. However, they are cost prohibitive to put into a pair of FPV goggles.

Are there better displays out? Absolutely.

Originally designed as a view finder in digital cameras, these micro displays are arguably the most expensive part of the FPV goggle. My guess is that they are the Sony ECX337A. Both the Fat Shark HDO 2 and the ORQA FPV.One use the same micro displays from Sony, the 0.5″ OLED.
