Laptop to TV - VGA to HDMI output is BLURRY!

Hi there,

Trying to hook a Dell Inspiron 1545 to my Samsung 32" LCD TV (LE32B450C4W).

I have a VGA to HDMI converter box but no matter what I do the resulting picture on the TV is blurred beyond belief. I have a feeling it could be the resolution, I hope it is not a faulty converter...

I have tried 1280 x 720 as the laptop screen resolution but the image is still unbearable. The max laptop screen res is 1366 x 768, if I could set it to 1920 x 1080 would that make any difference? I am using the 'duplicate' screens setting with regards to monitors 1 & 2 so laptop and TV are the same.

Or could it be something to do with the TV's firmware? It is about 4 years old it could do with an upgrade but I have absolutely no idea!

Very frustrating... Any help gratefully received!

Many thanks
Tom

don't use duplicate, as it will force it to the laptop resolution. You should be able to go full 1080p out of the vga port, but not in duplicate mode.

What do you get if you "Extend" instead of duplicate (in which case you could set a different resolution for the TV (try native) and Laptop?

Hi, when I choose extend the tv goes blank and I get a "No Signal" message. I also tried to set screen 2 as the default screen which works (albeit still blurred), and it gave me the option of all resolutions including 1920 x 1080 however when I selected that the screen went blank and said "no signal"...

Is this VGA to HDMI adapter powered? If not, it is not converting an analog (D-sub aka VGA) signal to digital (HDMI). I bought a VGA plus sound to HDMI converter for an old HP PC from Amazon and it works perfectly in 1920x1080 on my plasma; it looks just like an HDMI device would in 1080p. It uses a USB cable for the power that it needs to convert the signal to true HDMI. This is the exact product, but I paid much less for it (around $25). Newegg has one exactly like it for much less (I once saw it for $15 on their daily deal page): http://www.amazon.com/3-5mm-Stereo-Converter-Female-40H...


It is powered, not USB but by standard mains plug

Make sure the resolution you are trying to use is usable by the TV, find out what it's native resolution is. The Laptop resolution does not matter for this. Also make sure you set it to 60hz, although I ran a VGA to HDMI converter and had to set my TV to 59hz, but yours could be different.

If your TV supports DVI then go for a VGA to DVI converter. If it supports VGA then put it straight.

Hi there, the TV resolution is actually 1366 x 768 as I've just found out. And the refresh rate is correct, 60hz. Technology was supposed to make life easier....!!

Had to add this to the post, that TV looks to have a regular VGA input on it.
PC In (D-sub) 1

Why not just use that? No need for a converter, just get a VGA cable (you may have a few of them already) and use a regular 3.5mm male to male audio cable for the sound?


1280x720 should be right for this TV, the text will be fuzzy though, even with a DVI to HDMI direct cable. I have a 720p LCD monitor and the text is not the best, it's a bit broken up. Video looks pretty good though. If things are really annoying you, going to a 1080p monitor may help, but the issue may also be the converter you are using. The one I got was the Rosewill one, worked for me with my hardware and a Sharp Aquos older LCD (no PC inputs on it).
