Question about Dell UltraSharp 27 U2724DE
Hello, After analysis, I'm going to buy a Dell UltraSharp 27 U2724DE, with DisplayPort (2x) and HDMI (1x) ports for connecting the video signal. I have a VGA environment because of a KVM switch, all VGA ports. The PC(s)/Laptop(s) go to the switch in VGA, they come out in VGA to connect to the current VGA screen, 24" WUXGA 1920x1200. With the new environment, it's nice to keep everything as it was before, except using a male cable/adapter to exit the switch, from the female VGA output of the switch, to DisplayPort (in the case of HDMI) to the new screen. Is this type of cable/adapter available? How will the image on the screen react? My old one gave me: WUXGA 1920x1200, in VGA 24". The new screen is: QHD 2560 x 1440 pixels, 27". Thank you very much for your help. Best regards. Jannot

There is no active cable or adapter that directly converts a VGA (analogue) signal to DisplayPort (digital) to connect the VGA output of a KVM switch to the DisplayPort input of a monitor. Common adapters go from DisplayPort to VGA, not the other way round.
To use a display with DisplayPort input from a VGA source, you would need an active VGA to DisplayPort converter, which is a more complex and expensive electronic device, often sold separately. This type of converter adapts the analogue VGA signal into a digital DisplayPort signal.
As far as image quality is concerned, the VGA signal is limited in resolution and quality by its analogue nature. Your old 24" VGA screen displayed WUXGA 1920x1200. With a VGA to DisplayPort converter, the 27" QHD 2560x1440 screen will be able to display the maximum resolution, but the quality will be limited by the VGA source, so will probably be less sharp than with a native DisplayPort or HDMI source.
In short, to keep your VGA switch, you need an active VGA to DisplayPort converter. It's not just a passive cable or adapter. The image will depend on the quality of the converter and the original VGA resolution, which means it will be less than the screen's full QHD capacity.

Thanks for the answer.
I understand that the same scenario will apply in the VGA to HDMI situation.
Therefore:
1. Either I stay as I am
2. Or I buy a screen with a VGA port, at best WUXGA 1920x1200
3. Or I get rid of this switch and buy one with HDMI or similar.
Just ?
