Display problem with laptop connected to monitor

post #1 of 5
Thread Starter 
I'm having a problem while I connect my laptop to 2 different screens .. my laptop is a Toshiba T215 11.7".


The laptop native resolution is 1366x768.

When I connect the lap to a 23" BenQ 1080p screen I get 1920x1080 with no problem in the resolution options, connected via HDMI cable... BUT when I connect the laptop to the 30" HP-ZR30w I connect it via HDMI to DVI-D cable but I can only get 1280x800 rez, I thought I could atleast get 1920x1080 in the 30"" screen to, although its native is 2560x1600.

What am I missing here? is the problem the DVI-D end in the cable I use to connect the laptop ? the HP-ZR30w doesn't have HDMI in.


Help is appreciated, Thanks.

The problem is that you're trying to make your laptop do something it can't do. You can try running 1920x1200, but the HP-ZR30w may not have a full scalar capable of handling it.

HDMI can't be converted into DVI and still run 2560x1600 unfortunately. As it is, I do not think you will be able to do what you want your laptop to do.

Not trying to get 2560x1600 ... just 1080p like it can with the 23", the only difference is how its connected IN the monitor mmm...

Yeah, as I said, it doesn't have a scalar, which means it can't take a 1080p signal. If you realllly want it to display 1080p, you have to scale it at the video card end, and then send an upsampled 1080p signal at 1600p - which the connection can't take.

Basically, if you send the monitor a 1080p signal (what your HDMI port is capable of) your monitor can't display it because it has no scalar.
If you try to send it a 1600p signal (what the monitor needs) then your HDMI -> DVI connection can't handle it, since it's a single link connection only and isn't fast enough* to send 1600p signals.

In other words, you're screwed. Sorry. Besides, true 1080p on a HP ZR30w would look terrible (it's a 16:10 monitor)
