Are You Getting All the HDTV Resolution You Expected?
As a follow on to the post I made earlier, Are You Getting All Your Resolution?, I said then I would be surprised if many manufacturers would use the cheap out method of scaling the 1080i signal to 1080p by enlarging each 540p field to 1080 lines.
Home Theater’s Gary Merson did as promised and tested 54 sets to see how they deinterlaced the 1080i signal in the May 2006 report available here: Are You Getting All the HDTV Resolution You Expected? I highly recomment you read the article, especially if you are considering a new HDTV purchase.
Well, it turns out I’m surprised as almost half of the sets tested failed the test! Now there are some notable 1080p sets that were not tested like the new JVC 1080p jobs, but still it points out the need to check out any 1080p set you are thinking of purchasing before buying.
Here are the 1080p sets tested excerpted from the article:
| Make/Model | Technology | Pass/Fail |
| Epson LS65HD1 | 3LCD RP | Pass |
| Mitsubishi WD-62627 | DLP RP | Fail |
| Mitsubishi WD-73927 | DLP RP | Fail |
| Mitsubishi WD-52627 | DLP RP | Fail |
| Mitsubishi LC-3780 | LCD FP | Pass |
| Samsung HL-R5668 | DLP RP | Pass |
| Sharp LC-45GD5U | LCD FP | Fail |
| Sony KDSR60XBR1 | LCOS RP | Pass |
| Sony KDSR50XBR1 | LCOS RP | Pass |
| Westinghouse LVM-37W1 | LCD FP | Pass |
Now most sets tested were either 720p or 768p varities and it would also be undesirable, imo, to scale the 540p fields to their native resolutions rather than build a 1080 line video memory to be scaled to the native resolutions, but the results would not be as extreme as on the 1080p sets.
Bottom line is you should research a potental buy before plunking down big bucks.
Westinghouse has entered the 1080p market with some stellar LCD panels and they are reported to all pass the test. In addition to the above unit they offer the following:
Both of these units offer unusual value with the 42″ available for under $1,400 and the 37″ available for under $1,000.
