One more useless model on the market. 320x240 in 2018 year... why not 160x120 or 80x60?

How do they states an 86 degree FOV with a 320x240 screen? That picture would be so large but blurry that you couldn't possibly fly off of them.

You beat me on that question... I came up with the exact same conclusion... not only there is less pixels but with 86 FOV you may be able to see only half of them at once.

I just copy paste my answer from another thread here.

To clarify that open questions, I may speak for TOPSKY.

What is Prime1?
The first entry into FPV can be expensive, growing out of cheap gear is always around the corner.
We tried to create a good bang for the buck, threw in some safety features and wanna offer "Affordable FPV for everyone!"

The resolution topic:
Prime1 has a VR resolution of 640x480.
A Box Goggle (one screen) 640x480 equals to what the Prime1 (two screen) will produce.

The two big screens measure 2.4 inch which gives a better result than stretching out smaller screens. One great advantage of 2x bigger screens instead of 1x huge screen is to reduce the eye distance and therfore unit size for quite a lot.

Getting back to customer needs, the design is compact enough that we were able to add a built-in diopter.
Another feature that has been asked for was a RGB adjustment feature, which can greatly correct a cameras color misinterpretation.

The above mentioned EV100 comparison:
A 720x540, 0.xx inch micro-screen gets stretched to a 28 FOV; Our approach was different.
In our opinion, a high pixel density on a small screen can not display a colorful and bright picture, neither the higher resolution can deliver more details within a small FOV. We wanted more view! We listened to customers, and tried to do a better approach.

The antenna topic:
Prime1 comes with 2x 5.8g modules in diversity mode, each module has 2x SMA outputs which makes in total 4 antennas.

Speaking of reception, we can report that we could manage to have more than 2dBm additional sensitivity (RF speech -2dBm more) to built-in receivers in current competitor products in the same price category.
Each 6dBm step doubles range.

Especially in terms of antenna orientation and placement, as well as possibility to add directional antennas to get a better signal coverage, we speak of trying to get 360 degrees, the reason for that design. Each module can be deactivated to save power.

Yeah, That's not actually how resolution works with dual screen setups, but I guess we'll wait and see. Not gonna shoot it down before I see a review on them.

This "VR Resolution of 640x480" is nonsense. It seems like a trick to try to get "640x480" into the specs so people will not notice that the actual screen resolution is 320x240.

Nobody else specs their goggles this way. By this metric, HD2 resolution is 1600x1200. Okay then... but it's not. And it's B.S.

Nobody should make a 320x240 FPV goggle in 2018, at any price.

Nobody should buy a 320x240 FpV goggle in 2018, at any price.

For all my complaint about the EV100 with its tiny FOV, at least they had the sense to spec a high resolution screen.

This goggle is dead in the water, in my opinion. Which is a shame, because the 4x diversity receiver with antennas pointing out the side is actually very clever. The adjustable diopter is very clever (-8.00 diopter, which is even better, because most only go to -6.00 and I am -6.75 so this would be very good for me).

Dear Topsky: I said it about the F7X -- you are so close to making a very good goggle, and then you make a few mistakes that kill it. You're doing it again. Go back to the drawing board and re-make this goggle with minimum 640x480 screen and it might be okay. At 320x240, it is not even worth looking at.

I completely agree with Joshua.

I purchased my first video goggles from RangeVideo in 2009 and they were 640 X 480...

Agree with the above. There are compromises that are reasonable to save money on budget goggles (e.g. being big/bulky like box goggles) but screens that are even lower res than the low-res analogue signals we're already suffering is ridiculous.
