Different Panel in TV? - Can't get high resolution on PC

wackojackouk

Hi guys

Back in January I purchased a 24" Technika TV (http://direct.tesco.com/q/R.207-2229.aspx) whihc states it has a 1920x1080 resolution. Finally hooked it up a month ago and yep got 1920x1080 resolution on the Desktop PC so :j

However I noticed a big mark behind the screen after a couple of days (like two large blobs of dirt) so called Tesco who agreed to exchange.

Got the new TV home and it had about 6 dead pixels so it went straight back.

The latest one has no dead pixels but won't display a higher resolution than 1366 x 768. I spoke to support who told me that was the highest it went although the box clearly stated 1920 x 1080 and also the first TV did this no problem.

Deleted the onboard graphic drivers and I can get a 1920 x 10XX but the TV wasn't compatible so it showed an invalid format message. It would show 1600 x 1200 but it's not an optimal setting so I went back to 1280 x 768 whilst I try and solve the problem.

Something is weird here so I thought lets get a new graphics card and got my hands on a 256mb Nvidia card. Once installed got the 1600x1200 settings but needed to reboot and low and behold now it's using the latest Nvidia drivers the most I can get it up to is 1366 x 768.

I now think it must be something to do with the monitor but does anyone have any idea's what?

I noticed Tesco also do another 24" TV (http://direct.tesco.com/q/R.208-9554.aspx) and wonder if the wrong panel is in my TV.

Any thoughts anyone and should I complain. I am currently running at the 1280 x 768 and would like it a little bit higher as it's a bit bulky on the 24" TV.

Cheers

Both tellies are visually identical, going by the images on the website. Looks like they either gave you the wrong telly in the first place, or the wrong telly as a replacement.

i agree that they are have probably given you the wrong replacement as they are almost identical but on the box will say what the max Resolution is and on the second one it only goes to resolution 1366 x 768 which is really 1080i not 1080p as advertised so you try to return it on that basis .

I have a 22" Matsui TV which I bought from an auction. It states it is 1080p and indeed the Xbox 360 sees it as supporting 1080p but the panel is in fact 1366x768 and the TV downscales the picture.

Thanks guys, the more I think about the more I think it's the TV as the first one allowed me to go to the highest resolution straight away.

Any idea why if I delete the graphics drivers (for either the onboard or agp card) and windows installs the standard vga one it lets me select 1600 x 1200? - that's the only thing that makes me think it might not be the TV.

Thinking of buying another one to be honest as everything else is okay with the TV and providing the new one is ok taking the old one back for a refund (I presume I can do this with 28 days or so).

It does that because the computer doesn't know what the monitor is so lists all supported modes for the graphics card. You need to go to the TV manufacturers website and see if there is a .inf or driver file to download for the TV which will then tell Windows what resolutions and refresh rates the TV supports.

I thought that might be the case as well although I can't find anything for Technika. Their support line didn't even know they did a TV with a 1920 resolution. I even did a system restore to a day before I got the new TV and the settings were exactly the same - so I would hazard a guess for some reason the PC recognised the TV as being able to display higher (inbuilt .inf??? possible) and the new one is just somehow not right.

Any more suggestions as to what I can do?

768 has nothing to do with 1080i, apart from the fact they tend to allow 1080i signals (then downscaled to fit the screen). My pioneer is a 768 but allows 24Hz 1080P signals

Regardless. Id be sending the tv back as its clearly not a 1080P model

I'm not happy with it but just don't want to get another one and look a complete tool.... lol

One thing I noticed is that if I put TV on it says 576i - what's that compared to 720/1080

576i is standard television and dvd quality

Whats that like compared to 720P and 1080i/p? Not as good clearly

Hi guys

One other wierd thing today. Turned PC on and got a nice blue screen saying no display detected. Rebooted pc and same thing

Tried once more and got the black XP screen as normal but as it was loading it went to the blue screen saying no display connected.

I was thinking perhaps it could be the vga lead so will try and get hold of another one anyway and test.

However once I removed the AGP graphic card I installed on Friday (and was working fine albeit at the wrong resolution still) it seems to be ok (minus the wrong resolution).

So now after working ok but at wrong resolution on agp card on Friday now it doesn't work at all and there is some conflict.......:mad:

Argh.... Anyway I will try and hook up my old monitor this evening with both internal graphics and AGP graphics and check 1) they work and 2) the best resolution.

Any other thoughts or things I should check?

Cheers for all your input so far.
