The UC is curved, the EK is not. The panel is different.

The difference between the Gigabyte M32U models, especially between the "M32U-EK" and "M32U-UC" variants, lies mainly in the following aspects:

## Display technology and colour representation
- M32U-EK: Uses a SS IPS (Super Speed IPS) panel, which is known for its fast response time and good colour reproduction. It supports 10-bit colours, 90% DCI-P3 and 123% sRGB.
- M32U-UC: This variant also uses IPS technology, but there are no specific details that differentiate it from the EK variant in terms of colour display and panel types. However, it is likely that the UC variant has similar colour characteristics to the EK variant, but without specific details this cannot be confirmed.

## Additional functions
- M32U-EK: Provides functions such as KVM (Keyboard, Video, Mouse) Switch, OSD Sidekick, PIP/PBP, Dashboard, Black Equaliser and more.
- M32U-UC: There is no specific information to show whether this variant includes all or some of the above functions of the EK variant. It is possible that some functions may vary or be missing.

## General specifications
- Both models have a resolution of 3840 x 2160 pixels, a refresh rate of 144Hz and a response time of 1ms (GTG).

### Summary
- EK: Represents the standard version with SS IPS panel, comprehensive gaming functions and productivity functions such as KVM.
- UC: Without specific details, but probably similar basic functions as the EK variant, possibly with some differences in the additional functions or colour display.

For exact information on the specific differences between the models, I recommend consulting the manufacturer's official website or detailed product descriptions.
