Delphi (via Parallels) - blurry fonts on 27 inch monitor

[Joe Sansalone 6]

Hi,

 

I'm using Delphi 12 on a MacBook via Parallels (running Windows 11 ARM).

It looks good on the 14 inch Retina MacBook display.

 

But, when I connect to a 27 inch Dell monitor, the fonts look blurry.

 

Anyone in this situation, what can be done? AND how to save settings so that I can swap between External monitor 

and macbook?

 

thanks,

Joe

Hi Joe

I don't have any problem on my 4K monitor. Did you installed the Windows drivers of your screen (if Windows & Parallels detect it) ?

A new release of Parallels have been published this week, perhaps it will fix this problem with others "optimizations and bug fixes".

Hi Patrick, I installed the driver in windows.  For some reason Parallels uses its own driver and it sets color to 8-bit.  I changed the setting in Parallels to use "External display" graphics and it helps.  Also, I noticed that in Light mode (Delphi IDE), the fonts are crisp and sharp.  But, in dark mode, it's a little more blurry.  My external monitor is not 4K .. it's 2560 x 1440.

 

Seems like the color at 8-bits is not enough to make Dark mode look crisp.

(I made sure to allocate 16GB to Parallels VM, hoping it would change display to at least 16-bit color).

 

Thanks for the suggestions.

Can you share a screen capture (taken from the Mac) ?

 

On my M1 I have only 8 gb, Parallels and the VMs don't need more to work.

 

Are you in full screen mode or in "unity" with your VM in a window ?

Both full screen mode and "unity" produce the same effect.

The Parallels setting "Best for external displays", did produce better results ... but dark mode doesn't seem as crisp.

 

I will take a screenshot later today (currently working day job, monitor is connected to work windows laptop)

The Parallels "Best for external displays" does work.

 

I showed someone, and they saw the same clearness with Light mode and Dark mode.

It's my eyes on the Dark mode - I saw some "double" that made it look blurry .. but it's totally crisp as the Light mode.

When I increase font size even a little (code editor) it looks super sharp.

 

When it was set to "Retina Display" but had external monitor, there was a real blurriness because the resolution and scale (windows) 

were not using the native setting of the monitor.
