Please help about full HD with pc via LG 42" tv.

Hi guys,

Just bought the LG 42" 42LD490 from Currys. I've managed to get it set up via a dvi to hdmi lead so that I can use the pc through it. I did this before (using just a dvi lead) with my previous 720p 32" tv. My previous tv looked sharp as. I was expecting this one to look better, it's a better quality tv, and full HD which should make up for the increase in size.

The text doesn't look very sharp at all, and the icons aren't great. It looks like my 800 x 600 projector when I try to put 1024 x 768 through it, obviously in that case there aren't enough dots so it interpolates (I think the right word!). Now there should be enough dots here, so I can't see the problem. I've got a dvi -> hdmi lead v1.3 which should be enough. I've tried different res/tv options and can't get it much better. Game setting on cinema zoom aspect ration seems to be the best, not alot of difference between 1920 x 1080 and 1680 x 1050.

Phoned LG and they said to change the font setting to a bigger one, which of course makes it look better, but that's not the point, I want the bigger res with standard size text, otherwise I might as well have just bought a 720p again!

Any suggestions or anyone who has one can help me please??

Any settings on the TV you can change?

Sometimes you can tell the TV that the HDMI input is a PC Interface and it sharpens it all up. Turns off the interpolation I believe.

Yes mate, LG couldn't recommend any settings to change, but I've changed it to game mode and cinema zoom aspect ratio which is the best I can get it. I've tried every combo I can think of!

Pics in a few mins.

Thanks for the reply.

Sorry if they take a while to load, guess which one is from my laptop!

Now, I don't expect a tv to be perfect, but this is far worse than my previous 720p cheapo tv!

Notice the "e's" in particular, absolutely no definition on the tv, whereas on the laptop they are clearly defined.

I use my PC with two LG TV's as monitors both are fantastic, one is a 23" one is a 32", have also used our 47" for a while, you sure the PC is set to 1920*1080, also are you using the right HDMI port (should be labelled HDMI (DVI)), also in the TV menu set that sockets input name as PC.


Getting somewhere here! Have just changed HDMI 2 to pc, had no idea that you could do that!! (Neither did LG I guess otherwise they would've said!) Only reference I could find in the manual was telling me which cables to plug in, maybe I've missed that bit?

Anyway, it's different, not neccessarily better yet, but getting there I think. Will try hdmi1 now.

HDMI 1 the same, it's making a difference, but now the screen doesn't fill the screen if you see what I mean? Also can't set the aspect ratio as before so that's prob why it won't fill the screen.
#7
Getting somewhere here, 1776 x 1000 res with HDMI being labelled as pc is great!!!!!!
#8
Ok, so I can't work out how to make it full screen or higher res, so I've lost about 2-3 inches off my screen and some of the res that goes with it! About £30 worth of the tv lost in those few inches!!

Maybe a reboot will help? I'll try one with it set at 1920 x 1080. Back in a min.

Well, reset didn't help. Hoping LG will get back to me about this.

According to LG my gfx card (ati 3850) isn't powerful enough to run a 42" screen.

IT is, the size makes no difference, my crappy built in Intel can do 1920*1080.Anyway set it to 1920*1080 and it's too big, mine did this aswell. Make sure you're using HDMI 1 and have it labelled as PC, then turn off the TV and PC, then turn the TV back on and then boot up the PC, it should fit this time and be perfect, worked fine everytime after that. Just getting it the first time is a bit trial and error.

I know it can do the res, they say it can't do 42"!!! (I know they're wrong!!!)

You say 1920x1080 comes out too big? Mine doesn't, mine (now) comes out the same size as 1776 x1000 (since I labelled it as pc), ie squashed. I've labelled it as pc and tried both ports, they're labelled the same, just 1 and 2, they both say hdmi/dvi. I've reset loads of times hoping that it'll kick in some auto set up like I've seen on other tvs/monitors/projectors. But nothing!

They're phoning me back tomorrow as the other "expert" is in then, let's hope he's got something better than telling me the gfx card can't handle 42"!

Ah k, so you have black borders? Strange,I'm off to watch a film, will check back in about two hours.

Exactly mate, black borders. Losing about 3 inches of tv! I'll see what LG have to say tomorrow mate, I'm not doing anything more with it until tomorrow night now!

Thankyou for your help, you've got me a crisp 1776 x1000 which is good enough for now!

Didn't realise at the time that you could change the name of the hdmi input and that it would make a difference. LG were suprised this does anything and it's their tv!! Thanks for the help.

Keep playing with those TV settings. Also bare in mind that the native resolution for the TV for a PC interface might be different to what your expecting. IE. not 1920x1080, something else.

Just check the manual and it should tell you on the back pages I think, the refresh rate hz, the resolution, etc and so on. I am sure it is just a matter of messing around now on the TV and PC to get the right output.

Good luck.

Should be 1920 x 1080 I think, that's what LG said.
