AV Receiver and 4K UHD TV Crowdfunding for Better Reviews on CNX Software

I’ve written a fair amount of reviews, mostly of Android mini PCs and development boards, and I intend to continue, but there are currently a few things I’m unable to test: S/PDIF and HDMI pass-through, and 4K video output, 3D videos, and HDMI-CEC.  The main reason is that the AV receiver and TVs required to test this are rather expensive, and these are not something I really need personally, since I seldom watch movies myself, I purchased a new Full HD TV last year, and I don’t expect to access 4K content for a few more years.


Yet it would be interesting to prospective buyers to find out if advertized features such as audio pass-though of 5.1 & 7.1 codec does work, and whether 4K output (listed and real), HDMI-CEC, 3D videos and other features not supported by my current Panasonic can work properly. It would also be fun for me to test these features. That’s why I’ve been thinking of ways to get both an AV receiver and a 4K TV.

One way would be to get an AV receiver donated by companies such as Pioneer, Onkyo, or Yamaha, and a 4K TV by the likes of Sony, Panasonic, Samsung, or others. But even though CNX Software traffic has increased recently, I don’t think it’s a realistic option. So instead I’ve been thinking of raising funds by asking donations and selling some of the devices I used for review.

But first, let’s go through the requirements:

  • 4K TV – HDMI 2.0 for 2160p @ 60 Hz support, HDMI-CEC. Optional, but good to have: 3D video support, MHL, DisplayPort (are these found on TVs?)
  • AV Receiver – HDMI and S/PDIF input. Display showing Codec. 4K pass-through. Codec: Dolby Digital 5.1, Dolby Digital+ 5.1/7.1, TrueHD 5.1/7.1, DTS HD, and DTS MA

This type of devices would allow me to complete my current review process. I’ve also seen AV receivers claiming 9.2 channel and Dolby Atmos support, but I’ve never read anybody ask for these, and the price is even higher. So I’m gone to my local consumer electronics shop (Sahapanich) to check what’s available, and so far the cheapest options I’ve found matching the requirements are:

  • LG UB830T 49″ 4K UHD TV – 54,999 Baht ($1,672). That’s the catalog price, and I’ve been told the actual price would be a bit lower. [Update: It looks like this model can be found for only 35,000 Baht online (~$1065)]
  • Onkyo TX-NR626 AV receiver – 19,999 Baht ($605).

That means I’d need to raise around $2,200, which is quite higher than I initially anticipated. The HDMI 2.0 (2160p 60Hz) requirement somehow increase the price of the TV a lot, as I could get something for around $1,000 with HDMI 1.4, and DTS-HD, 7.1 channel adds about $100 compared to a 5.1 system with speakers. So if anybody, especially people living in Thailand, knows cheaper options that would fulfill the requirements, that would be greatly helpful, and I’d be able to lower the target amount to raise.


The plan is to run the campaign for 10 days (until 19 January 2015), accept payment by Paypal, and if we can’t raise enough money, I’d just click on the refund button in Paypal, since I don’t really need donations to run the blog itself. If you’d like to donate, select the 4K UHD TV or AV receiver options below.

Funded! Thank you!

If rather that just donating, you’d rather buy one of the reviewed sample, at a small discount, you can contact me by email if you are interested. I’ll also wait the end of the campaign before shipping, and if case I can’t raise enough fund, I’ll ask whether you still want it or would like a refund before shipping. I would use EMS within Thailand, and Small Packet registered Airmail to the rest of the word.

I want to keep at least one sample for each processor, especially the 4K capable SoC (Rockchip RK3288, Amlogic S802/S812, and Allwinner A80), so I’ll keep at least three samples for this purpose.

I’ll keep track of the progress daily (net amount) in the table below, splitting the funding for TV and receiver respetively by 2/3 and 1/3 at first, but I may make adjustments as needed at the end of the campaign. The funding does not start from zero, as include 10,000 Baht for the television, and 3,000 Baht for the AV receiver to get started. I’ve also sold 4 device locally since I though about purchasing a 4K TV and AV receiver, bringing in 9079 Baht net, as well as a $10 donation (Thanks Nikolai) which I’ve split between the TV and receiver.

* I’ve re-allocated more funds from sold devices to the AV receiver, since I’ve been able to confirm LG 42UB820T model supports HDMI 2.0, so that’s probably the one I’ll buy for 23,000 Baht or less. The only feature missing is 3D support, but not that many people may be interested in 3D videos, and it adds a lot to the cost. I’ll also need to buy speakers with the AV receiver, and probably choose another model due to HDMI issues with Onkyo TX-NR626. So I think the crowdfunding is already successful, and I’ll buy both a 4K TV and AV Receiver, I just need to decide where, and choose another AV receiver model. *

** The crowdfunding campaign is now complete, and I consider it successful as I could buy an AV receiver (Onkyo TX-NR636 for 25,000 baht) and a 4K TV( LG 42UB820T for 19,610 Baht after getting lucky with a 10% coupon this morning), and I still have to buy some speakers.
Here’s the details of this crowdfunding with Paypal fees and shipping:

So thanks to my readers, I managed to raise 28,035 Baht, and after adding device sales (9,079 Baht) made previously, and 13,000 Baht out of my pocket, I’ve got a ~50,112 Baht budget to purchase the equipment needed. I’ve already spent 44,610 for the largest expenses, and I have 5,500 baht left for the speakers. **

That’s it. I think I covered everything. Whatever happens, everybody wins. If enough money is raised, I’ll be able to purchase a 4K UHD TV and/or an AV Receiver, and my reviews will be more detailed with 4K output, HDMI-CEC, HDMI and S/PDIF pass-through testing, but if not, I’ll have a little less work to do, keep a bit more of my savings, and I’ll organize another giveaway week with some of the devices above.
