we decided to give these Full HD TVs a go from Panasonic TX-P42S20B They are Full 1080i HD and look stunning The "S" is the cheapest of the pack but still a stunning picture. Trying to use a VGA - HDMI convertor from Maplins and also one from HDCable.co.uk but the TVs won't accept the incoming HDMI signal Why not ? The convertors seem to work having tried them on other Monitors and TVs But not on this Panasonic TV. the instructions on the convertor box says its converting any VGA/SVGA and higher into HDMI...

 

Any Suggestions?

The other thing that might be worth trying is a DVI to HDMI adaptor cable (assuming of course that you have a computer with a DVI output). These are cheap enough to buy as an experiment, and my hunch is they may work a bit more straightforwardly.

 

Interesting....Most of the PCs we are coming across only have VGA 15 pin output. These TVs are a Cheaper idea for Exhibition display. The Professional Panasonic Plasma with input boards, loudspeakers and Industrial table stands add upto about £2k now and the TVs are £450 +VAT

Do you have the ability to select the output resolution of your converters?

 

As far as I know Nick its set to HDMI output 1.2a It says that they accept all the various Inputs from 640 x 480 upto 1280 x 1024

 

One possible explanation follows:

It seems to me that this unit is probably not scaling the output, and therefore if you feed in VGA 640x480 you may be getting a digital version of 640x480 and if you feed in 1280x1024 you may be getting a digital 1280x1024. It is also possible that your Panasonic Plasma will only accept resolutions such as 576i 576p 480i 480p 720p 1080i and 1080p on its HDMI input. (If it has a DVI input - this may work via a passive adaptor)

 

Your units may just not be compatible.

As I read down this topic from the top that was my thought as well. A few site showing units which look similar to the Maplin unit mention that it does analogue to digital conversion - nothing about scaling.

I'm certain that is your problem. I work a lot with Sony BRAVIA screens and they will only accept 'TV' resolutions on their HDMI inputs - 480i/480p/576i/576p/720p/1080i/ 1080p(in some cases) and not the other VESA resolutions despite accepting a must bigger range of inputs over VGA/HD15. The solution is to use a combined scaler/format convertor. I have used a variety of things to do this with including this although I reliase it's a bit pricey, but it's great for situations where you want a fixed output resolution that should work with whatever someone throws at it.

At this point I hope that it is OK to recommend one surefire way to avoid the problems that have been mentioned above. I appreciate that the solution is more expensive than what has been attempted up to now, but....

 

The Kramer VP-434 http://www.kramerelectronics.co.uk/product...del.asp?pid=725 which has a seven year RTB warranty and list price of £449.

Interesting......I understand that there are different resolustions out of the PC but I thought these convertors converted the analogue signal to HDMI digital input. Seems they don't I appreciate the Kramer suggestion thanks Nick. We will keep trying to find a cheaper alternative otherwise we may as well purchase more of the Industrial Commercial Plasmas at £2k a pop

 

Cheers

These TVs are a Cheaper idea for Exhibition display. The Professional Panasonic Plasma with input boards, loudspeakers and Industrial table stands add upto about £2k now and the TVs are £450 +VAT

 

Just to hoik this off topic, but the reason that the 'Industrial' panels have the additional cost is partly the warranty - Consumer panels will not be covered for commercial use, so if you have a panel that dies, then there may well be a refusal to repair the unit under warranty. My wife works for a Waitrose Food and Home store, and during her time on the TV section, a plasma returned for warranty repair had the claim rejected, as the panels log file showed daily use from 09:00 to 17:30. Turned out to have been bought by an Estate Agent... Then there are also the additional cooling fans and other bits an pieces that make them more rental friendly, as well as the higher build quality.

Interseting Pete....My Plasma at home seems to have far more use than the Industrial Plasmas we put on Exhibitions...Serious..
