Ok, then why does the same display work perfectly in windows? The display supports full RGB both 8 and 10 bit uncompressed. There is an open issue for this on the driver gitlab repo.
Don’t monitor shame me please. Also, the pixel density is within 5% of my 27" 1440p monitors.
We don’t tend to use air/air heat pump systems in the UK, even for new builds, always air/water.
Because of lower water temperature output of heat pumps compared to the gas boilers they replace, usually you need to increase the size of radiators to be able to achieve a room temperature change in a reasonable time. What is being referred to as efficiently, is actually just a measure of performance of the radiator, not actual energy efficiency.
