U2515H, no signal from ThinkPad T510, VGA to DP
Hi Chris,
I am using a dual monitor setup with ThinkPad T510 which has a VGA and Display port on the laptop. So,I am using DP to the first monitor and VGA to DP adapter to the second monitor. The first monitor works fine, second doesn't. If I swap the cable, say VGA to DP adapter to first and DP direct connection to second, second monitor works and first doesn't. So, I have narrowed the problem to VGA to DP setup. But I am not sure why it won't work. Could you please help?
Thanks
Archana

The U2515HX and U2515H are the same monitor. The U2515HX shipped with the HDMI to HDMI cable and DP to mDP cable. The U2515H only shipped with the DP to mDP cable.
A Laptop VGA out port cannot upconvert to a monitor DP/mDP in port. The adapter you bought is designed to do the opposite =
Laptop DP out port --> DP to VGA adapter --> VGA to VGA cable --> Monitor VGA in port
I need data on that second monitor.
ThinkPad T510 video out ports = DP/VGA
U2515H video in ports = DP/mDP/HDMI
Second monitor video in ports = ???

Yes. But the ThinkPad T510 VGA out port will not drive up to the U2515H optimal 2560x1440 60Hz resolution. All you will get is 1920x1080 60Hz.
ThinkPad T510 DP out port --> DP to mDP cable --> #1 U2515H mDP in port
ThinkPad T510 VGA out port --> VGA to VGA cable --> $15.99 VGA to HDMI adapter --> HDMI to HDMI cable --> #2 U2515H HDMI in port
