Sony Vaio VGN-SR29VN: Problem with VGA and HDMI

by liaky / June 21, 2010 4:38 AM PDT

Hi all,

I'm running a Vaio laptop (32-bit MS Vista, 4Gb RAM and ATI's Mobility Radeon HD 3470). 3 months ago I bought a Samsung B2230 monitor to plug into my laptop but came across some problems (I posted the same message in CNET?s Samsung forum as I'm not sure if the issue lies with the laptop or monitor).

Problem 1 ?

At first, I used a VGA cable for connection and set resolution to the full 1080. This was mostly fine except for some annoying horizontal waves that vibrated across the screen. I checked for interference but I think the monitor was far enough from the speakers and my mobile phone. All my drivers are up-to-date too but I can't figure out what it is. I use VGA cables at work all the time with laser projectors and have never had a problem, so is this a common issue with VGA and monitors?

Problem 2 ?

I've started using an HDMI cable to solve this and continued on 1080 resolution. The image is now completely stable but all text on screen - from my Firefox browser to iTunes, Office programs and even folders in Windows - are unclear. The spaces within many letters are yellow in colour and the gaps between the letters are yellow too (when it should all be matching whatever the background colour is). I've noticed it affects some letters (m, h, t, l, i, a, u) more than others. It?s making text look very patchy.

I've made sure all drivers are the latest, and I played around with ATI controls (CCC) setting pixel format to Full RGB. The latter seems to have improved things, but not completely solved it.

Problem 3 ?

Again with the HDMI cable, whether I choose small, medium or large desktop icons, all the icons get clumped together in one great mess when I turn on auto grid alignment. I can?t change icon names either by slowly double-clicking them, and it forces me to right click and go to ?rename?.

As you can see, lots of little annoyances since using HDMI not to mention the painfully slow startup speed! Never seen this before and it?s really weird...

Does anybody know what's going on here?!

Thanks for your help!

", so is this a common issue with VGA and monitors?"

Sadly yes and last week I changed to HDMI for the same reason. HOWEVER I knew to use Windows 7's advice for the native resolution and then let CLEAR TYPE have a go at this.

Sorry if I decline to write a tutorial here but the VGA connection is analog and subject to interference.
