Budget boards end up so fun to type on

oh, fair enough. i get that modding comment you made initially now... you'd be surprised though - many people i know prefer the hollow sound of undamped plastic. and there are a load that don't really care about sound too much like me i do agree with budget switches + long sessions... there are a lo

Backlight

Re "Is there any way to boost the brightness of the backlight of the key itself?": Presuming it is already at maximum brightness by Fn + W (or Fn + knob (if the keyboard has a knob)), only by using keycaps with better shine-through characteristics That may be difficult for the south-facing LEDs on t

Keychron K4 V2 white led looks yellowish?

First reset to factory defaults Unspecific, but par for the course is resetting to factory defaults and reflashing the keyboard firmware. Though reflashing the keyboard firmware is risky business for the original K series with proprietary keyboard firmware (which includes the K4 V2). It is a differe

Consoom all the keyboards.

I don’t have as many keyboards as a person in a post, but from what I tried, I was surprised by the quality of evo75. I couldn’t believe how affordable, beautiful and high quality it is. I also suggest you to pay attention to what layout you prefer ISO or ANSI. It is quite important, I absolutely pr

Holding Alt stops some keys from working

(K4 V2 is in the original K series. Only K4 V3 got QMK support.) It probably doesn't apply to the original K series, but RGB light off is a problem for some later Keychron keyboards.

Connectivity issues with the K4 V2.

Re "Keychron Launcher doesn't detect the keyboard even if it's directly connected via USB (with data transfer cable); VIA isn't compatible with the K4": Yes, the original K series, including the K4 V2, has proprietary firmware and doesn't support the Via protocol. (K4 V3 got QMK (and thus Via) suppo

Keychron K4 won't connect with Bluetooth, can't remove device

keychron K4 V2 Как не стараюсь, у меня Bluetooth даже не видит её, зато сам моментально подключается, но при этом она вообще никак не реагирует на нажатия

Just got an K17 MAX - can you increase the caps lock brightness? I cannot see it when on...

Re "can you increase the Caps Lock brightness?": Yes, drill a hole in the keycap Or get another keycap with better shine-through characteristics. But that will not be easy. Making the plate underneath more reflective may also be sufficient. The inside of the keycap could also be made more reflective

Does anyone else keystroke input lag this bad?

Nope. What about those people who's bluetooth adapters are away from their case on a hub. I have tried my BT on my MB, a dongle and a dongle on a hub that sits on my desk, about 2m away from my PC. The ONLY way that i get this fucking keyboard (K4 v2) to work as it should is with a cable. Regardless
