Thailand Posted December 31, 2023 Share Posted December 31, 2023 Another cable question. Old TV only has AV outlet, 3 pin red,white yellow. Currently connects to an old Android box again via AV cable. Getting a new android box but the TV is OK so does not need changing. Just realised the new box does not have AV only HDMI access. I have seen that the AV HDMI cables are available so simply asking is this likely to work connecting the old TV - AV to the new box HDMI? I will know when I do get the new box and AV HDMI cable and try it myself but just asking if anyone has had similar experience? Thanks Link to comment Share on other sites More sharing options...
OneMoreFarang Posted December 31, 2023 Share Posted December 31, 2023 I am not so sure an AV-HDMI "cable" will work. But there are lots of converters out there that are cheap. I.e. Lazada starting from 59THB. So I am pretty sure you will find something that will work and is not expensive. 1 1 Link to comment Share on other sites More sharing options...
Georgealbert Posted December 31, 2023 Share Posted December 31, 2023 Many years ago, used an HDMI to AV converter. Yes it worked, but lost picture quality. I got a new TV fairly quickly. If your android box is receiving decent UHDTV or 4K channels, I think you will be disappointed. Unless things have improved in recent years, which I doubt, as old technology. 1 1 Link to comment Share on other sites More sharing options...
Thailand Posted December 31, 2023 Author Share Posted December 31, 2023 Much as I expected. The old TV is wall mounted in the bedroom and a new version appears to be about a quarter of the price of the old one! So will try the "cable" approach first if not successful a new TV for the new year! 1 Link to comment Share on other sites More sharing options...

JaiMaai Posted December 31, 2023 Share Posted December 31, 2023 Be careful and make sure you buy an HDMI to AV cable/adapter/ A lot (all?) of them only work one way round so buying an AV - HDMI adapter might not work. Link to comment Share on other sites More sharing options...

The old TV appears to be working on elastic bands , masking tape and seat of the pants so your assumption may well be correct! Off to the January sales!

brianthainess Posted December 31, 2023 Share Posted December 31, 2023 The price of new Smart TVs has dropped dramatically in recent years, by at least 50%. even more if you take inflation into account. 2-3 K for 32'', the first one I had cost me 12k but it won't connect to the internet anymore. so brought a bigger one.

By definition the picture quality of HDMI if much better than AV. It is impossible to convert high definition HDMI to AV. It is possible to convert AV to HDMI without much quality loss. But because of the limitations of AV it will never be as good as HDMI from a HDMI source. Link to comment Share on other sites More sharing options...

TV is mounted above a door so only allows max size 43 inches! So looks like I can get what I will need around the 4K mark. Link to comment Share on other sites More sharing options...

I currently have a 4k bluray outputting over hdmi to a hdmi to av (480i) converter thence to the av inout on the tv with no issues other than mild picture quality as would be expected. the converter is Mini HDMI2AV i can upload picture later if needed. Available on Amazon here, but from PRC so should be available. Link to comment Share on other sites More sharing options...

Fully agree, I was only using standard TV source when I used a converter, and found it had not only effect on the quality, but distorted picture size also. Would think HDTV, UHDTV and 4 K sources it would be pointless. Link to comment Share on other sites More sharing options...

I remember I watched VHS 40 years ago and we enjoyed the movies and didn't think about possible better quality at that time. Some people make the mistake that they think all must be in the highest resolution to look good. No, it's not necessary. It's nice to have but old, low resolution, is not by definition bad. It's just not as good as what's available now. Link to comment Share on other sites More sharing options...

My old Sony trinitron tube from the early 1980s actually looks remarkably good with the downsampled and converted signal. It is different from the digital signal used now, but resolution isn’t the be all end all. Edited December 31, 2023 by degrub 1 Link to comment Share on other sites More sharing options...

It is like watching the same channel online, HD and then comparing what I get through my local cable supplier, in Sattahip, you never watch cable again. That includes the Thai channels. Older movies, VHS, are going to look the same, so no problem. I never watch much TV, but would not want to limit the experience for a few 000 baht.

I've always thought that our posters recommending other members spend for tech they don't particularly want or need should be required to transfer the extra funds to the member's bank account.

By the way, I only talked about the loss in quality the OP may expect, did I recommend spending anything. I said I would limit my experience for a few 000 baht. Seems you did not like my reply in another thread, so you try to be smart here, maybe get that skin thin tested. Disingenuous. The OP doesn't have a decent TV and is therefore a loser? YOU wouldn't limit YOUR experience? Topic ain't about you. Transfer the money to the OP for that decent TV. Use PM to get the account number. 1 Link to comment Share on other sites More sharing options...
