HDMI vs DVI quality comparison on LG M227WD-PZ TV monitor 1080p filmed with FZ100
part1: @0:00 view angle HDMI&DVI split screen and each alone see how yours looks at
http://www.lagom.nl/lcd-test/viewing_angle.php (btw thanks lagom.nl)
part2: @0:46 desktop
part3: @1:21 DVI & HDMI closeup
part4: @3:59 clips from The Seeker HDMI+DVI split screen
part5: @5:19 only HDMI part
part6: @6:40 only DVI part
part7: @8:00 monitor (menu) settings for DVI
part8: @8:20 monitor (menu) settings for HDMI
(those were the settings used)
- all content recorded with Panasonic DMC-FZ100 (on a tripod and/or handheld) aimed at an LG Flatron M227WD-PZ LCD monitor(distance between camera and monitor: approx. 120-128cm), with DVI and HDMI connectors from a PC video card Sapphire Vapor-X HD 4870 2048 MB (which has 3 outputs: DVI, HDMI, DSUB)
- videos taken in 1920x1080x50i iA mode, except the movies with The Seeker(first episode) clips those were iso 400(I think), F3.4 E1/30, AF-L, AE-L
- video was recorded as interlaced(by FZ100), but it was deinterlaced by Sony Vegas Pro 10 (description too long...)
- cleartype was enabled in windows 7
- monitor and desktop resolution: 1920x1080x60Hz
- there is no audio for this video
- video was rendered as progressive using Sony Vegas Pro 10.0 64bit
- the monitor has 2x HDMI inputs (HDMI1 was tested) and each HDMI has it's own settings (in menu-picture)
- both DVI and HDMI connectors were connected at all times, and ATI was set to duplicate desktop on both outputs (can only duplicate desktop on 2 of the 3 outputs, one must be disabled - ie. can't duplicate or extends desktop on all 3 outputs at the same time, only one 2 of the 3, any 2)
- some images were used from:
http://www.lagom.nl/lcd-test within firefox with F11 key to enter fullscreen also with Full Screen addon to remove top band
- in HDMI, Just Scan makes the desktop look the same size as in DVI's 16:9, but 16:9 in HDMI will zoom in a little, so the edges of desktop are cut out (not shown in video)
own deductions:
- for desktop (ie. text) DVI has better quality than HDMI
- for movies HDMI has better quality
- the monitor is doing extra processing (perhaps the so called XD Engine) when input is from HDMI, and apparently no processing when input is from DVI - hence the text looks perfect with DVI; with HDMI the text has artifacts similar to chromatic aberations (cleartype was enabled; though with cleartype disabled the chromas are not visible near the text though the text seems more pixelated than with DVI - this comparison is not shown in video)
See the original uploaded mp4 file here(approx. 269MB) split in two .rar parts (due to 200MB file limit on mediafire) thus I provide two direct download links:
