DELL E193FP input lag and response time

Measured using the pi lagtester PRO.

19 inch 4:3 screen. 1280x1024 resolution, doesn't support interlaced modes. Only VGA in. 

At 60hz:

Input lag (first response at top of the screen) is always 6ms independent of resolution.

Scanout (top to bottom) takes 16ms.

Response time is awful, about 22ms. 

Thus, to see a pixel respond at the lower edge of the screen takes about 6 + 16 + 22ms = 44ms. Yuck. 

Interestingly this display supports 75hz, which improves things. The response at the bottom of the screen improves from 44ms to 38ms.

Since this is an old obscure LCD I've not bothered to add it to the database or do a full review.

Panasonic TH-42PX75U Plasma TV review: input lag and upscaling tested using the piLagTesterPRO

Image
This 720p Plasma TV from 2008 is very unique and quite nice in many ways. It used to retail for around $1300. If you can find one it's a great choice for retro gaming.  Overview/Image quality This is a plasma TV, which generally means at least the following: nearly infinite viewing angles, and jaw dropping weight. That's true in this case as well. This 42" model weights 75lbs.  At native resolution (720p) this TV crops 20 pixels off the top/bottom and 30 off the sides. 480p/i crops 20 pixels off all sides. Both modes have aliasing, too, though it's not too bad. There's really no excuse for aliasing on a TV this big: you know the panel was designed specifically to be a tv. Why not hit 720p exactly? And as for 480p/i, they could have at least offered a zoomed out mode with black borders and 1:1 pixel mapping. But no such luck. There are zoom/stretch options to crop even more, but none that crop less. While the native resolution supposedly is 1366 x 768 it does accept

piLagTester PRO order page

The piLagTesterPRO measures your monitor's input lag and response time. It is a cheap, full featured add-on to the Raspberry Pi; I provide the sensor and required software, you provide the Pi (a $5 pi Zero is more than sufficient). Although it has a DIY aesthetic, it is quite functional and in fact offers quite a lot more features than the commercial alternatives (Leo Bodnar and the Time Sleuth), and has been tested with over 40 TVs, including 4k models .  Here's what it looks like in action: The pi draws a black background, and then roughly once a second displays a set of target rectangles (top/middle/bottom). You place the sensor over the desired target, and the piLagTester measures the monitor's response starting from the moment the frame of video data is sent over the Pi's HDMI port. This is plotted in the graph, which is sideways for space reasons. The lag tester measures two thresholds. In red it shows how long it takes for the monitor to start displaying t

How to pause animation in PowerPoint

If you have a long animation looping animation that you want to be able to pause and then resume, there's an easy way to do so with the keyboard. Press the 1 key, which puts you in the mode where you can type in a slide number to jump to. In this mode, all animation is paused. To get out of this mode without jumping to another slide press the ~ key. There are lots of keyboard shortcuts in Powerpoint; press F1 to get a list. Note that one of them is listed as "pause" (S key or + key) but this doesn't actually seem to work in all the situations that the trick described above does. Tested an known to work in PPT 2003.
