Hardware – Display, Calibration, GPU
4K Screen (windows)
I use a 4K screen with 150% display for everyday life (internet, etc …).
But I need the maximum definition of my 4K screen for photo processing and approach: 1 screen pixel = 1 DC pixel.
In other words, approach the 1: 1 permanent display on the screen.
– Icon properties / Change DPI settings / Overide scaling = Application
The font size of the menus is small. With PhotoLab this is not the most important element.
Calibrate the screen
During calibration it is necessary to adjust the brightness to 80 cd/m2 in order to have a comparable brightness on the screen and the paper before printing.
Users who do not print or use other software, the brightness should not exceed 100 cd/m2.
For color calibration, see this excellent site (in french).
Can you point me to an equivalent website in English?

Graphics card benchmark (GPU)
During installation, DxO runs a GPU performance test to suggest the best export settings.
Sometimes a GPU running faster than the CPU does not meet the requirements. DxO has to consider additional constraints, for example Windows forbids the screen to be frozen for more than 2 seconds. It is up to the user to decide (force usage).
Purchasing tips
Choose a latest generation graphics card to benefit from the most complete instruction sets.
The difficulty is to select the right card at the right price.
Aim to Nvidia RTX 3xxx or 4xxx, AMD Radeon RX 6xxx or 7xxx.
The important parametre for PhotoLab is FP32 (5 à 10 TFLOPS are enough).
You can compare your GPU with those recommanded by DxO.
